Association Between Neurological Disorders and Death by Suicide in Denmark

Prevalence of Suicidality in Adolescents With Newly Diagnosed Focal Epilepsy at Diagnosis and Over the Following 36 Months

BACKGROUND AND OBJECTIVES

Individuals with epilepsy have increased risk of suicidal ideation (SI) and behaviors when compared with the general population. This relationship has remained largely unexplored in adolescents. We investigated the prevalence of suicidality in adolescents with newly diagnosed focal epilepsy within 4 months of treatment initiation and over the following 36 months.

METHODS

This was a post hoc analysis of the enrollment and follow-up data from the Human Epilepsy Project, an international, multi-institutional study that enrolled participants between 2012 and 2017. Participants enrolled were 11-17 years of age within 4 months of treatment initiation for focal epilepsy. We used data from the Columbia Suicide Severity Rating Scale (C-SSRS), administered at enrollment and over the 36-month follow-up period, along with data from medical records.

RESULTS

A total of 66 adolescent participants were enrolled and completed the C-SSRS. At enrollment, 14 (21%) had any lifetime SI and 5 (8%) had any lifetime suicidal behaviors (SBs). Over the following 36 months, 6 adolescents reported new onset SI and 5 adolescents reported new onset SB. Thus, the lifetime prevalence of SI within this population increased from 21% to 30% (14-20 adolescents), and the lifetime prevalence of SB increased from 8% to 15% (5-10).

DISCUSSION

The prevalence of suicidality in adolescents with newly diagnosed focal epilepsy reported in our study is consistent with previous findings of significant suicidality observed in epilepsy. We identify adolescents as an at-risk population at the time of epilepsy diagnosis and in the following years.

Suicide within five years of hospital-treated self-harm: A data linkage cohort study

BACKGROUND

Hospital-treated self-harm is a strong predictor of suicide and hospital contacts may include missed opportunities for suicide prevention. We conducted a data linkage study to identify factors associated with suicide in people treated in hospital for self-harm in Victoria, Australia.

METHOD

We undertook a cohort study following 14,307 people treated in hospital for an episode of self-harm (i.e., either admitted or non-admitted ED presentations) over the period 2011 and 2012 and used data from the Victorian Suicide Register to identify suicides within 5 years. We estimated unadjusted hazard ratios (HRs) for suicide using survival analysis for each exposure variable and then computed adjusted HRs using a multivariate model that included all exposure variables.

RESULTS

Among females, the risk of suicide was higher in those aged 50-74 years (HR 1.78; Cl: 1.02, 3.10), residing in areas of least disadvantage (HR 2.58; Cl: 1.21, 5.50), who used hanging as a method of self-harm (HR 5.17; Cl: 1.86, 14.35) and with organic disorders (HR 6.71; Cl: 2.61, 17.23) or disorders of adult personality and behaviour (HR 2.10; Cl: 1.03, 4.27). In males, the risk of suicide was higher in those who used motor vehicle exhaust gas (MVEG) as a method of self-harm (HR 3.48; Cl: 1.73, 7.01), and with disorders due to psychoactive substance abuse (HR 1.75; Cl: 1.14, 2.67).

CONCLUSION

Although all patients should be routinely assessed for risk and needs following hospital-treated self-harm including appropriate follow-up care, people who use MVEG or hanging as methods of self-harm are obvious candidates for close follow-up.

Suicidal ideation in people with multiple sclerosis and its association with coping self-efficacy

BACKGROUND

Chronic neurological disease such as multiple sclerosis (MS), is a significant risk factor for psychological distress, which can result in suicidal behaviour. Suicidal ideation (SI) is considered a harbinger of suicide-related mortality. However, so far, little is known about the role of protective factors against SI in MS.

OBJECTIVE

This study aims to assess the association between coping self-efficacy and SI when controlled for sociodemographic variables, clinical variables, sleep-related problems, and depression.

METHODS

The study sample consisted of 162 people with MS, was predominantly female (75.9 %), the mean age was 40.9 ± 11.4 years, the mean disease duration was 11.7 ± 7.1 years, and the mean functional disability score was 3.55 ± 1.1. We used the Coping Self-Efficacy scale (CSE), the General Health Questionnaire-28 (GHQ-28), the Expanded Disability Status Scale (EDSS), the Hospital Anxiety and Depression Scale (HADS), the Pittsburgh Sleep Quality Index (PSQI), and the Multidimensional Fatigue Inventory (MFI). Multiple linear regressions were utilized to statistically analyse the data.

RESULTS

All assessed coping self-efficacy dimensions were significantly associated with SI in MS when controlled for sociodemographic variables, clinical variables, sleep-related problems, and depression. Furthermore, all assessed coping self-efficacy dimensions were able to alleviate the negative association between income, depression and SI.

CONCLUSION

People with MS may significantly benefit from psychological support aimed at promoting coping self-efficacy and utilization of various coping strategies. Problem-focused coping, coping focused on getting support, and coping focused on stopping unpleasant thoughts and feelings seem to have comparable associations with SI, and thus interventions aimed at empowering any of these dimensions may be beneficial in diminishing the severity of SI.

Causal relationship between rheumatoid arthritis and epilepsy in a European population: a univariate and multivariate Mendelian randomization study

Background

Several previous studies have reported an association between rheumatoid arthritis (RA) and epilepsy, but the causal relationship is unclear. The aim of this study was to assess the connection between RA and epilepsy in a European population using Mendelian randomization (MR).

Methods

Genome-wide association study summary data on RA and epilepsy from European populations were included. Univariate MR (UVMR) and multivariate MR were used to investigate the causal relationship between the two conditions. Three analysis methods were applied: inverse variance weight (IVW), MR-Egger, and weighted median, with IVW being the primary method. Cochran Q statistics, MR-PRESSO, MR-Egger intercept, leave-one-out test, and MR-Steiger test were combined for the sensitivity analysis.

Results

UVMR showed a positive association between RA and epilepsy risk (OR=1.038, 95% CI=1.007-1.038, p=0.017) that was supported by sensitivity analysis. Further MVMR after harmonizing the three covariates of hypertension, alcohol consumption, and smoking, confirmed the causal relationship between RA and epilepsy (OR=1.049, 95% CI=1.011-1.087, p=0.010).

Conclusion

This study demonstrated that RA is associated with an increased risk of epilepsy. It has emphasized that the monitoring of epilepsy risk in patients diagnosed with RA should be strengthened in clinical practice, and further studies are needed in the future to explore the potential mechanism of action connecting the two conditions.

Clarifying the relationship between physical injuries and risk for suicide attempt in a Swedish national sample

INTRODUCTION

The Interpersonal-Psychological Theory of Suicide proposes that capability for suicide is acquired through exposure to painful and provocative events (PPEs). Although there is robust evidence for a positive association between aggregate measures of PPEs and risk for suicidal behavior, little is known about the contributions of physical injuries. The present study investigated the relationship between injuries and risk of subsequent suicide attempt (SA).

METHODS

Data were from Swedish population-based registers. All individuals born in Sweden between 1970 and 1990 were included (N = 1,011,725 females and 1,067,709 males). We used Cox regression models to test associations between 10 types of injuries (eye injury; fracture; dislocation/sprain/strain; injury to nerves and spinal cord; injury to blood vessels; intracranial injury; crushing injury; internal injury; traumatic amputation; and other or unspecified injuries) and risk for later SA. Analyses were stratified by sex and adjusted for year of birth and parental education. Additional models tested for differences in the pattern of associations based on age group and genetic liability for SA. In co-relative models, we tested the association between each injury type and risk for SA in relative pairs of varying genetic relatedness to control for unmeasured familial confounders.

RESULTS

All 10 injury types were associated with elevated risk for SA (hazard ratios [HRs] = 1.2-7.0). Associations were stronger in the first year following an injury (HRs = 1.8-7.0), but HRs remained above 1 more than 1 year after injury exposure (HRs = 1.2-2.6). The strength of associations varied across injury type, sex, age, and genetic liability for SA. For example, the magnitude of the association between crushing injury and risk for SA was larger in females than males, whereas other injuries showed a similar pattern of associations across sex. Moreover, there was evidence to support positive additive interaction effects between several injury types and aggregate genetic liability for SA (relative excess risk due to interaction [RERI] = 0.1-0.3), but the majority of these interactions became non-significant or changed direction after accounting for comorbid psychiatric and substance use disorders. In co-relative models, the pattern of associations differed by injury type, such that there was evidence to support a potential causal effect of eye injury, fracture, dislocation/sprain/strain, intracranial injury, and other and unspecified injuries on risk for SA. For the remaining injury types, HRs were not significantly different from 1 in monozygotic twins, which is consistent with confounding by familial factors.

CONCLUSIONS

Injuries are associated with increased risk for subsequent SA, particularly in the first year following an injury. While genetic and familial environmental factors may partly explain these associations, there is also evidence to support a potential causal effect of several injury types on future risk for SA.

Is Late-Onset Suicidal Behavior a Distinct Subtype?

This clinical viewpoint article aims to draw attention to a yet unexplored factor influencing suicidal behavior: age of onset of suicidal behavior. To tackle the substantial heterogeneity among depressed older attempters, we suggest consideration of at least two distinct pathways to suicidal behavior in late life based on when the first suicidal crisis occurred. Specifically, we discuss the current state of research and the rationale behind the suggested early-late-onset categorization of late-life suicidal behavior. We summarize available evidence so far on early-onset and late-onset attempters, and the potential heterogeneity in the interplay of risk/precipitating factors. Certain risk factors for suicide, such as impulsivity and borderline traits, decrease with age, while memory and broader cognitive impairments increase with age. Research indicates that familial/social exposure to suicidal behavior, childhood trauma, impulsivity, maladaptive personality traits, longstanding interpersonal difficulties, and legal problems are found predominantly in attempters experiencing their first suicidal crisis between youth and early midlife. In contrast, dementia prodrome is one of the most promising but understudied candidates for late-onset suicide risk, especially in the context of other risk factors. Moreover, personality traits conferring increased vulnerability to late-onset suicidal behavior (such as high conscientiousness) are not the same as ones classically identified in younger attempters and in older suicide attempters who have early-onset suicidal behavior (such as neuroticism and Cluster B traits). We discuss methodological points about studying age of onset of suicidal behavior, outline clinical implications, share ideas for future directions, and call for research on this understudied topic.

"So at least now I know how to deal with things myself, what I can do if it gets really bad again"-experiences with a long-term cross-sectoral advocacy care and case management for severe multiple sclerosis: a qualitative study

BACKGROUND

Persons with severe Multiple Sclerosis (PwsMS) face complex needs and daily limitations that make it challenging to receive optimal care. The implementation and coordination of health care, social services, and support in financial affairs can be particularly time consuming and burdensome for both PwsMS and caregivers. Care and case management (CCM) helps ensure optimal individual care as well as care at a higher-level. The goal of the current qualitative study was to determine the experiences of PwsMS, caregivers and health care specialists (HCSs) with the CCM.

METHODS

In the current qualitative sub study, as part of a larger trial, in-depth semi-structured interviews with PwsMS, caregivers and HCSs who had been in contact with the CCM were conducted between 02/2022 and 01/2023. Data was transcribed, pseudonymized, tested for saturation and analyzed using structuring content analysis according to Kuckartz. Sociodemographic and interview characteristics were analyzed descriptively.

RESULTS

Thirteen PwsMS, 12 caregivers and 10 HCSs completed interviews. Main categories of CCM functions were derived deductively: (1) gatekeeper function, (2) broker function, (3) advocacy function, (4) outlook on CCM in standard care. Subcategories were then derived inductively from the interview material. 852 segments were coded. Participants appreciated the CCM as a continuous and objective contact person, a person of trust (92 codes), a competent source of information and advice (on MS) (68 codes) and comprehensive cross-insurance support (128 codes), relieving and supporting PwsMS, their caregivers and HCSs (67 codes).

CONCLUSIONS

Through the cross-sectoral continuous support in health-related, social, financial and everyday bureaucratic matters, the CCM provides comprehensive and overriding support and relief for PwsMS, caregivers and HCSs. This intervention bears the potential to be fine-tuned and applied to similar complex patient groups.

TRIAL REGISTRATION

The study was approved by the Ethics Committee of the University of Cologne (#20-1436), registered at the German Register for Clinical Studies (DRKS00022771) and in accordance with the Declaration of Helsinki.

Randomized Controlled Comparative Effectiveness Trial of Risk Model-Guided Clinical Decision Support for Suicide Screening

Suicide prevention requires risk identification, appropriate intervention, and follow-up. Traditional risk identification relies on patient self-reporting, support network reporting, or face-to-face screening with validated instruments or history and physical exam. In the last decade, statistical risk models have been studied and more recently deployed to augment clinical judgment. Models have generally been found to be low precision or problematic at scale due to low incidence. Few have been tested in clinical practice, and none have been tested in clinical trials to our knowledge.

Methods

We report the results of a pragmatic randomized controlled trial (RCT) in three outpatient adult Neurology clinic settings. This two-arm trial compared the effectiveness of Interruptive and Non-Interruptive Clinical Decision Support (CDS) to prompt further screening of suicidal ideation for those predicted to be high risk using a real-time, validated statistical risk model of suicide attempt risk, with the decision to screen as the primary end point. Secondary outcomes included rates of suicidal ideation and attempts in both arms. Manual chart review of every trial encounter was used to determine if suicide risk assessment was subsequently documented.

Results

From August 16, 2022, through February 16, 2023, our study randomized 596 patient encounters across 561 patients for providers to receive either Interruptive or Non-Interruptive CDS in a 1:1 ratio. Adjusting for provider cluster effects, Interruptive CDS led to significantly higher numbers of decisions to screen (42%=121/289 encounters) compared to Non-Interruptive CDS (4%=12/307) (odds ratio=17.7, p-value <0.001). Secondarily, no documented episodes of suicidal ideation or attempts occurred in either arm. While the proportion of documented assessments among those noting the decision to screen was higher for providers in the Non-Interruptive arm (92%=11/12) than in the Interruptive arm (52%=63/121), the interruptive CDS was associated with more frequent documentation of suicide risk assessment (63/289 encounters compared to 11/307, p-value<0.001).

Conclusions

In this pragmatic RCT of real-time predictive CDS to guide suicide risk assessment, Interruptive CDS led to higher numbers of decisions to screen and documented suicide risk assessments. Well-powered large-scale trials randomizing this type of CDS compared to standard of care are indicated to measure effectiveness in reducing suicidal self-harm.

Mood disorders in adults with epilepsy: a review of unrecognized facts and common misconceptions

Epilepsy is one of the most common neurologic conditions. Its clinical manifestations are not restricted to seizures but often include cognitive disturbances and psychiatric disorders. Prospective population-based studies have shown that people with epilepsy have an increased risk of developing mood disorders, and people with a primary mood disorder have an increased risk of developing epilepsy. The existence of common pathogenic mechanisms in epilepsy and mood disorders may explain the bidirectional relation between these two conditions. Recognition of a personal and family psychiatric history at the time of evaluation of people for a seizure disorder is critical in the selection of antiseizure medications: those with mood-stabilizing properties (e.g., lamotrigine, oxcarbazepine) should be favoured as a first option in those with a positive history while those with negative psychotropic properties (e.g., levetiracetam, topiramate) avoided. While mood disorders may be clinically identical in people with epilepsy, they often present with atypical manifestations that do not meet ICD or DSM diagnostic criteria. Failure to treat mood disorders in epilepsy may have a negative impact, increasing suicide risk and iatrogenic effects of antiseizure medications and worsening quality of life. Treating mood disorders in epilepsy is identical to those with primary mood disorders. Yet, there is a common misconception that antidepressants have proconvulsant properties. Most antidepressants are safe when prescribed at therapeutic doses. The incidence of seizures is lower in people randomized to antidepressants than placebo in multicenter randomized placebo-controlled trials of people treated for a primary mood disorder. Thus, there is no excuse not to prescribe antidepressant medications to people with epilepsy.

Neurologic morbidity and functional independence in adult survivors of childhood cancer

OBJECTIVE

To examine associations between neurologic late effects and attainment of independence in adult survivors of childhood cancer treated with central nervous system (CNS)-directed therapies.

METHODS

A total of 7881 survivors treated with cranial radiation therapy (n = 4051; CRT) and/or intrathecal methotrexate (n = 4193; IT MTX) ([CNS-treated]; median age [range] = 25.5 years [18-48]; time since diagnosis = 17.7 years [6.8-30.2]) and 8039 without CNS-directed therapy reported neurologic conditions including stroke, seizure, neurosensory deficits, focal neurologic dysfunction, and migraines/severe headaches. Functional independence was assessed using latent class analysis with multiple indicators (independent living, assistance with routine and personal care needs, ability to work/attend school, attainment of driver's license, marital/partner status). Multivariable regression models, adjusted for age, sex, race/ethnicity, and chronic health conditions, estimated odds ratios (OR) or relative risks (RR) for associations between neurologic morbidity, functional independence, and emotional distress.

RESULTS

Among CNS-treated survivors, three classes of independence were identified: (1) moderately independent, never married, and non-independent living (78.7%); (2) moderately independent, unable to drive (15.6%); and (3) non-independent (5.7%). In contrast to 50% of non-CNS-treated survivors and 60% of siblings, a fourth fully independent class of CNS-treated survivors was not identified. History of stroke (OR = 2.50, 95% CI: 1.70-3.68), seizure (OR = 9.70, 95% CI: 7.37-12.8), neurosensory deficits (OR = 2.67, 95% CI: 2.16-3.31), and focal neurologic dysfunction (OR = 3.05, 95% CI: 2.40-3.88) were associated with non-independence among CNS-treated survivors. Non-independence was associated with emotional distress symptoms.

INTERPRETATION

CNS-treated survivors do not attain full independence comparable to non-CNS-treated survivors or siblings. Interventions to promote independence may be beneficial for survivors with treatment-related neurological sequalae.

Suicides in degenerative neurocognitive disorders and traumatic brain injuries

BACKGROUND

Neuropsychiatric symptoms in major neurocognitive disorders have been strongly associated with suicidality.

METHODS

The objectives were to explore suicide rates in degenerative neurocognitive disorders (DNDs), alcohol-related neurocognitive disorders (ARNDs), and traumatic brain injuries (TBIs). Patients who received these diagnoses between 1998 and 2015 (N = 231,817) were identified from nationwide registers, and their mortality was followed up until December 31, 2018. We calculated incidences of suicides per 100,000 person-years, types of suicides, and suicide rates compared with the general population (standardized mortality ratio [SMR]).

RESULTS

During the follow-up, 0.3% (95% confidence interval [95% CI]: 0.2-0.5) of patients with DNDs, 1.1% (0.7-1.8) with ARNDs, and 1.0% (0.7-1.3) with TBIs committed suicide. Suicide mortality rate was higher in men (58.9, 51.3, to 67.4 per 100,000) than in women (9.8, 7.5, to 12.5 per 100,000). The highest suicide rate was in ARNDs (98.8, 65.1, to 143.8 per 100,000), followed by TBIs (82.0, 62.4, to 105.8 per 100,000), and DNDs (21.2, 18.3, to 24.5 per 100,000). The SMRs (95% CI) were 3.69 (2.53-5.38), 2.99 (2.31-3.86), and 1.31 (1.13-1.51), respectively, and no sex difference emerged. The most common cause of death was self-inflicted injury by hanging or drowning (12.4, 10.3, to 14.8 per 100,000).

CONCLUSIONS

Suicide rates were higher in all three patient groups than the general population. Suicide risk remained elevated for more than 10 years after diagnosis. The suicide methods were mostly violent.

Geographical variation in treated psychotic and other mental disorders in Finland by region and urbanicity

PURPOSE

In Finland, prevalence of schizophrenia is higher in the eastern and northern regions and co-occurs with the distribution of schizophrenia polygenic risk scores. Both genetic and environmental factors have been hypothesized to contribute to this variation. We aimed to examine the prevalence of psychotic and other mental disorders by region and degree of urbanicity, and the impacts of socio-economic adjustments on these associations.

METHODS

Nationwide population registers from 2011 to 2017 and healthcare registers from 1975 to 2017. We used 19 administrative and three aggregate regions based on the distribution of schizophrenia polygenic risk scores, and a seven-level urban-rural classification. Prevalence ratios (PRs) were calculated by Poisson regression models and adjusted for gender, age, and calendar year (basic adjustments), and Finnish origin, residential history, urbanicity, household income, economic activity, and physical comorbidity (additional adjustments) on an individual level. Average marginal effects were used to visualize interaction effects between region and urbanicity.

RESULTS

A total of 5,898,180 individuals were observed. All mental disorders were slightly more prevalent (PR 1.03 [95% CI, 1.02-1.03]), and psychotic disorders (1.11 [1.10-1.12]) and schizophrenia (1.19 [1.17-1.21]) considerably more prevalent in eastern and northern than in western coastal regions. After the additional adjustments, however, the PRs were 0.95 (0.95-0.96), 1.00 (0.99-1.01), and 1.03 (1.02-1.04), respectively. Urban residence was associated with increased prevalence of psychotic disorders across all regions (adjusted PR 1.21 [1.20-1.22]).

CONCLUSION

After adjusting for socioeconomic and sociodemographic factors, the within-country distribution of mental disorders no longer followed the traditional east-west gradient. Urban-rural differences, on the other hand, persisted after the adjustments.

Mental health outcomes of encephalitis: An international web-based study

BACKGROUND AND PURPOSE

Acute encephalitis is associated with psychiatric symptoms. Despite this, the extent of mental health problems following encephalitis has not been systematically reported.

METHODS

We recruited adults who had been diagnosed with encephalitis of any aetiology to complete a web-based questionnaire.

RESULTS

In total, 445 respondents from 31 countries (55.1% UK, 23.1% USA) responded. Infectious encephalitis constituted 65.4% of cases, autoimmune 29.7%. Mean age was 50.1 years, 65.8% were female, and median time since encephalitis diagnosis was 7 years. The most common self-reported psychiatric symptoms were anxiety (75.2%), sleep problems (64.4%), mood problems (62.2%), and unexpected crying (35.2%). Self-reported psychiatric diagnoses were common: anxiety (44.0%), depression (38.6%), panic disorder (15.7%), and posttraumatic stress disorder (PTSD; 21.3%). Severe mental illnesses such as psychosis (3.3%) and bipolar affective disorder (3.1%) were reported. Self-reported diagnosis rates were broadly consistent with results from the Psychiatric Diagnostic Screening Questionnaire. Many respondents also reported they had symptoms of anxiety (37.5%), depression (28.1%), PTSD (26.8%), or panic disorder (20.9%) that had not been diagnosed. Rates of psychiatric symptoms did not differ between autoimmune and infectious encephalitis. In total, 37.5% respondents had thought about suicide, and 4.4% had attempted suicide, since their encephalitis diagnosis. More than half of respondents (53.5%) reported they had no, or substandard, access to appropriate mental health care. High rates of sensory hypersensitivities (>75%) suggest a previously unreported association.

CONCLUSIONS

This large international survey indicates that psychiatric symptoms following encephalitis are common and that mental health care provision may be inadequate. We highlight a need for proactive psychiatric input.

Risk of Suicidal Ideation and Behavior in Individuals With Parkinson Disease: A Systematic Review and Meta-Analysis

Importance

Suicide risk may be increased in patients with Parkinson disease (PD), a common neurodegenerative condition. Mood disorders, especially depression, are prevalent in patients with PD who report suicidality.

Objective

To address inconsistent results from studies of suicidal ideation and behavior in patients with PD.

Data Sources

The study team searched MEDLINE and Embase from inception to June 14, 2023, and further screened the bibliographies of relevant studies to ensure a comprehensive search.

Study Selection

Original studies, published in English, discussing either suicidal ideation, behavior, or both in adults with PD were included. Accepted study designs included cross-sectional, case-control, and cohort studies. Studies that only included patients with PD after deep brain stimulation were excluded.

Data Extraction and Synthesis

This meta-analysis was conducted in line with the PRISMA guidelines. Two authors reviewed each study and extracted the data independently, with discrepancies referred to a third independent author.

Main Outcomes and Measures

Outcomes included the prevalence of suicidal ideation and behavior, measured as proportions, and the risk of suicidal behavior in patients with PD relative to controls, measured in both odds ratio (OR) and hazards ratio (HR).

Results

A total of 28 studies comprising 505 950 PD patients were included in the final analysis. The prevalence of suicidal ideation was evaluated in 14 studies (22.2%; 95% CI, 14.6-32.3) and suicidal behavior in 21 studies (1.25%; 95% CI, 0.64-2.41). Excluding 4 outliers, prevalence of suicidal behavior was significantly higher in prospective studies (1.75%; 95% CI, 1.03-2.95) than retrospective studies (0.50%; 95% CI, 0.24-1.01). Excluding 1 outlier, OR of suicidal behavior was pooled across 10 studies and significant (OR, 2.15; 95% CI, 1.22-3.78; P = .01). HR of suicidal behavior was assessed in 9 studies (HR, 1.73; 95% CI, 1.40-2.14; P < .001).

Conclusions and Relevance

This meta-analysis involving more than 500 000 patients with PD found 22.2% and 1.25% of patients with PD to have suicidal ideation and behavior, respectively. Patients with PD had 2 times the risk of suicidal behavior than controls. Early recognition and management of suicidality in PD can help reduce mortality.

Psychiatric Disorders Before and After Dementia Diagnosis

Importance

Little is known about the specific timing and sequence of incident psychiatric comorbidities at different stages of dementia diagnosis.

Objectives

To examine the temporal risk patterns of psychiatric disorders, including depression, anxiety, stress-related disorders, substance use disorders, sleep disorders, somatoform/conversion disorders, and psychotic disorders, among patients with dementia before, at the time of, and after receipt of a diagnosis.

Design, Setting, and Participants

This population-based, nationwide cohort study analyzed data from 796 505 participants obtained from 6 registers between January 1, 2000, and December 31, 2017, including the Swedish registry for cognitive/dementia disorders. Patients with dementia were matched on year of birth (±3 years), sex, and region of residence with up to 4 controls. Data were analyzed between March 1, 2023, and August 31, 2023.

Exposures

Any cause of dementia and dementia subtypes.

Main Outcomes and Measures

Flexible parametric survival models to determine the time-dependent risk of initial diagnosis of psychiatric disorders, from 7 years prior to dementia diagnosis to 10 years after diagnosis. Subgroup analysis was conducted for psychiatric drug use among persons receiving a diagnosis of dementia from January 1, 2011, to December 31, 2012.

Results

Of 796 505 patients included in the study (mean [SD] age at diagnosis, 80.2 [8.3] years; 448 869 (56.4%) female), 209 245 had dementia, whereas 587 260 did not, across 7 824 616 person-years. The relative risk of psychiatric disorders was consistently higher among patients with dementia compared with control participants and began to increase from 3 years before diagnosis (hazard ratio, [HR], 1.72; 95% CI, 1.67-1.76), peaked during the week after diagnosis (HR, 4.74; 95% CI, 4.21-5.34), and decreased rapidly thereafter. Decreased risk relative to controls was observed from 5 years after diagnosis (HR, 0.93; 95% CI, 0.87-0.98). The results were similar for Alzheimer disease, mixed dementia, vascular dementia and unspecified dementia. Among patients with dementia, markedly elevated use of psychiatric medications was observed in the year leading up to the dementia diagnosis and peaked 6 months after diagnosis. For example, antidepressant use was persistently higher among patients with dementia compared with controls, and the difference increased from 2 years before dementia diagnosis (15.9% vs 7.9%, P < .001), peaked approximately 6 months after dementia diagnosis (29.1% vs 9.7%, P < .001), and then decreased slowly from 3 years after diagnosis but remained higher than controls 5 years after diagnosis (16.4% vs 6.9%, P < .001).

Conclusions and Relevance

The findings of this cohort study that patients with dementia had markedly increased risks of psychiatric disorders both before and after dementia diagnosis highlight the significance of incorporating psychiatric preventative and management interventions for individuals with dementia across various diagnostic stages.

Population-attributable risk of psychiatric disorders for suicide among adolescents and young adults in Taiwan

BACKGROUND

Youth suicide rates have increased markedly in some countries. This study aimed to estimate the population-attributable risk of psychiatric disorders associated with suicide among Taiwanese youth aged 10-24 years.

METHODS

Data were obtained from the National Death Registry and National Health Insurance (NHI) claims database between 2007 and 2019. Youth who died by suicide were included, and comparisons, 1:10 matched by age and sex, were randomly selected from the Registry for NHI beneficiaries. We used multivariable logistic regression to estimate suicide odds ratios for psychiatric disorders. The population-attributable fractions (PAF) were calculated for each psychiatric disorder.

RESULTS

A total of 2345 youth suicide and 23 450 comparisons were included. Overall, 44.8% of suicides had a psychiatric disorder, while only 7.9% of the comparisons had a psychiatric disorder. The combined PAF for all psychiatric disorders was 55.9%. The top three psychiatric conditions of the largest PAFs were major depressive disorder, dysthymia, and sleep disorder. In the analysis stratified by sex, the combined PAF was 45.5% for males and 69.2% for females. The PAF among young adults aged 20-24 years (57.0%) was higher than among adolescents aged 10-19 years (48.0%).

CONCLUSIONS

Our findings of high PAF from major depressive disorder, dysthymia, and sleep disorder to youth suicides suggest that youth suicide prevention that focuses on detecting and treating mental illness may usefully target these disorders.

Knowledge and Attitudes towards Epilepsy of Croatian General Student Population and Biomedical Students: A Cross-Sectional Study

Epilepsy causes a significant burden to patients as it is linked with various somatic and psychiatric comorbidities, social issues, impaired quality of life, and increased mortality. Improving the population's knowledge and attitudes about epilepsy patients could be beneficial as it could raise social awareness and lead to more social support for patients. For those reasons, a survey-based cross-sectional study was conducted to determine Croatian students' knowledge and attitudes toward epilepsy. A previously developed survey questionnaire was adapted for the Croatian setting and distributed online to the students (n = 544). Croatian students generally had positive attitudes towards people with epilepsy (median score 28.0, interquartile range 29.0-26.0, with the minimum possible score being 0.0 and the maximum 30.0), with the female gender (B (male) = 0.664 (95% CI -1.158, -0.170), p = 0.009), biomedical education (B (other) = -0.442, (95% CI -0.823, -0.061), p = 0.023), and personal experience in the form of witnessing the seizure (B = 0.519 (95% CI 0,098, 0.940), p = 0.016) as predictors of more favorable attitudes. Overall knowledge was satisfactory concerning most items, with the exception of first aid measures and risk factors. Educational intervention targeting bio-medical students and other students who might, in their future professional lives, be responsible for people suffering from epilepsy is needed to improve the gaps in their knowledge.

Factors related to the severity of obsessive-compulsive symptoms and their impact on suicide risk in epileptic patients

OBJECTIVE

To explore relevant factors for the severity of obsessive-compulsive symptoms (OCSs) in adult epileptic patients and investigate whether the severity of OCSs is a mediator in the relationship between depressive/anxiety symptoms and suicide risk in epileptic patients.

METHODS

This was a cross-sectional study from a hospital in Northeast China. Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Neurological Disorders Depression Inventory for Epilepsy (NDDIE), Generalized Anxiety Disorder (GAD-7), and Nurses' Global Assessment of Suicide Risk (NGASR) were used to assess the severity of OCSs, depressive symptoms, anxiety symptoms, and suicide risk in epileptic patients, respectively. The independent factors of the severity of OCSs and their mediating effects in the relationship between depressive/anxiety symptoms and suicide risk were evaluated by regression analyses and mediator models, respectively.

RESULTS

NDDIE scores (β = 0.404, p < 0.001), GAD-7 scores (β = 0.247, p = 0.009), and polytherapy (β = 0.119, p = 0.032) were the independent factors of Y-BOCS scores. The Y-BOCS scores partially mediated the relationship between GAD-7 scores and NGASR scores (standardized coefficients of indirect effect = 0.109, Bootstrap 95% CI = 0.024 to 0.214). Still, they did not mediate the relationship between NDDIE scores and NGASR scores (standardized coefficients of indirect effect = 0.062, Bootstrap 95% CI = -0.024 to 0.169).

CONCLUSIONS

Depressive symptoms, anxiety symptoms, and polytherapy are independently associated with the severity of OCSs in epileptic patients. Depressive and anxiety symptoms mediate the effect of the severity of OCSs on suicide risk in epileptic patients completely.

Use of Psychoactive Medications and Risk of Suicide in Late Life (75+): A Total Population Study

BACKGROUND

Psychoactive medications play an important role for the mental health and risk of suicidal behaviour in the oldest segment of the population (75+). A better understanding of psychoactive medication use is advocated to prevent suicide in this age group.

PURPOSE

We investigated the risk of suicide associated with the use of psychoactive medications in the total population aged ≥ 75 years, with and without exposure to antidepressants.

METHOD

A national population-based register study, including all Swedish residents aged ≥ 75 years between 2006 and 2014 (N = 1,413,806). A nested case-control design was used to investigate psychoactive medications associated with suicide among users and non-users of antidepressants. Risk estimates were calculated in adjusted conditional logistic regression models for the entire cohort and by gender.

RESULTS

Suicide occurred in 1305 persons (907 men and 398 women). Among them, 555 (42.5%) were on an antidepressant at the time of suicide. Adjusted incidence rate ratio (aIRR) for suicide was increased in those who were on hypnotics in the total cohort (aIRR 2.05, 95% confidence interval 1.74 to 2.41), in both users and non-users of antidepressants and for both genders. Elevated suicide risk was observed in those who concomitantly used anxiolytics with antidepressants (1.51, 1.25 to 1.83). Decreased risk of suicide was observed among those who were on anti-dementia drugs, in the total cohort (0.33, 0.21 to 0.52) and in both users and non-users of antidepressants. Use of antipsychotics and mood stabilisers showed no effect on suicide risk.

CONCLUSION

Use of hypnotics and concomitant use of anxiolytics with antidepressants was associated with increased risk of late-life suicide. Our findings suggest the need for careful evaluation of the benefit-risk balance of psychoactive medications as well as their availability as a possible suicide means. Future research should consider the indication of use of the psychoactive medications and the severity of psychiatric and medical illnesses of the patients.

External Causes of Death From Death Certificates in Patients With Dementia

OBJECTIVES

We aim to analyze the risk of death from specific external causes, including falls, complications of medical and surgical care, unintentional injuries, and suicide, in dementia patients.

DESIGN

Swedish nationwide cohort study integrating 6 registers from May 1, 2007, through December 31, 2018, including the Swedish Registry for Cognitive/Dementia Disorders (SveDem).

SETTING AND PARTICIPANTS

Population-based study. Patients diagnosed with dementia from 2007 to 2018 and up to 4 controls matched on year of birth (±3 years), sex, and region of residence.

METHODS

The exposures of this study were diagnosis of dementia and dementia subtypes. Number of deaths and causes of mortality were obtained from death certificates compiled into the Cause of Death Register. Hazard ratios (HRs) and 95% CIs were estimated using Cox and flexible models, adjusted for sociodemographics, medical and psychiatric disorders.

RESULTS

The study population included 235,085 patients with dementia [96,760 men (41.2%); mean age 81.5 (SD 8.5) years] and 771,019 control participants [341,994 men (44.4%); mean age 79.9 (SD 8.6) years], over 3,721,687 person-years. Compared with control participants, patients with dementia presented increased risk for unintentional injuries (HR 3.30, 95% CI 3.19-3.40) and falls (HR 2.67, 95% CI 2.54-2.80) during old age (≥75 y), and suicide (HR 1.56, 95% CI 1.02-2.39) in middle age (<65 y). Suicide risk was 5.04 times higher (HR 6.04, 95% CI 4.22-8.66) in patients with both dementia and 2 or more psychiatric disorders relative to controls (incidence rate per person-years, 1.6 vs 0.3). For dementia subtypes, frontotemporal dementia had the highest risks of unintentional injuries (HR 4.28, 95% CI 2.80-6.52) and falls (HR 3.83, 95% CI 1.98-7.41), whereas subjects with mixed dementia were less likely to die from suicide (HR 0.11, 95% CI 0.03-0.46) and complications of medical and surgical care (HR 0.53, 95% CI 0.40-0.70) compared to controls.

CONCLUSIONS AND IMPLICATIONS

Suicide risk screening and psychiatric disorders management in early-onset dementia and early interventions for unintentional injuries and falls prevention in older dementia patients should be provided.

Regaining Autonomy in a Holding Environment: Patients' Perspectives on the Existential Communication with Physicians When Suffering from a Severe, Chronic Illness: A Qualitative Nordic Study

Patients experience existential themes as pivotal in their lives, in order to be able to live with a severe, chronic illness; however, physicians report a hesitative approach to existential communication. The current study investigated Nordic patients' experiences of existential communication with their physicians related to the treatment of multiple sclerosis or chronic pain. Semi-structured interviews with 23 patients were analyzed following Interpretative Phenomenological Analysis. Physicians focusing on medical aspects at the expense of psychological and existential aspects of being ill was experienced by patients as challenging their treatment and well-being. For making a shared decision with the physician on their treatment, patients needed a transition from being dependent to being autonomous. A holding environment and existential communication about transitional objects such as relationships with something bigger than themselves, as nature or religion, supported this autonomy. The analysis showed that existential communication not only supported patients in developing and regaining autonomy but also functioned as a moderator for illness-related distress, as a prevention of withdrawal from treatment, and as significant for patients in relation to living with chronic illness. Further education in existential communication is desirable, to support physicians integrating existential dimensions in consultations and shared decision-making with patients suffering from a severe, chronic illness.

Physical injuries as triggers for self-harm: a within-individual study of nearly 250 000 injured people with a major psychiatric disorder

BACKGROUND

Although there is robust evidence for several factors which may precipitate self-harm, the contributions of different physical injuries are largely unknown.

OBJECTIVE

To examine whether specific physical injuries are associated with risks of self-harm in people with psychiatric disorders.

METHODS

By using population and secondary care registers, we identified all people born in Finland (1955-2000) and Sweden (1948-1993) with schizophrenia-spectrum disorder (n=136 182), bipolar disorder (n=68 437) or depression (n=461 071). Falls, transport-related injury, traumatic brain injury and injury from interpersonal assault were identified within these subsamples. We used conditional logistic regression models adjusted for age and calendar month to compare self-harm risk in the week after each injury to earlier weekly control periods, which allowed us to account for unmeasured confounders, including genetics and early environments.

FINDINGS

A total of 249 210 individuals had been diagnosed with a psychiatric disorder and a physical injury during the follow-up. The absolute risk of self-harm after a physical injury ranged between transport-related injury and injury from interpersonal assault (averaging 17.4-37.0 events per 10 000 person-weeks). Risk of self-harm increased by a factor of two to three (adjusted OR: 2.0-2.9) in the week following a physical injury, as compared with earlier, unexposed periods for the same individuals.

CONCLUSIONS

Physical injuries are important proximal risk factors for self-harm in people with psychiatric disorders.

CLINICAL IMPLICATIONS

Mechanisms underlying the associations could provide treatment targets. When treating patients with psychiatric illnesses, emergency and trauma medical services should actively work in liaison with psychiatric services to implement self-harm prevention strategies.

Suicidal Thoughts and Behaviors in Anti-NMDA Receptor Encephalitis: Psychopathological Features and Clinical Outcomes

OBJECTIVE

A wide variety of neuropsychiatric symptoms are described during the acute phase of anti-N-methyl-d-aspartate receptor encephalitis (ANMDARE), including psychosis, mania, depression, and catatonia, but there are few reports on suicidal thought and behaviors in ANMDARE. To address this gap in the literature, the authors measured the presence of suicidal thoughts and behaviors among a large cohort of Mexican patients diagnosed with definite ANMDARE.

METHODS

This observational and longitudinal study included patients with definite ANMDARE hospitalized at the National Institute of Neurology and Neurosurgery of Mexico between 2014 and 2021. Suicidal thoughts and behaviors were assessed before and after treatment by means of a clinical interview with relatives and a direct clinical assessment with each patient. Thoughts of engaging in suicide-related behavior and acts of suicidal and nonsuicidal self-directed violence before and during hospitalization were recorded.

RESULTS

From a total sample of 120 patients who fulfilled the diagnostic criteria for definite ANMDARE, 15 patients (13%) had suicidal thoughts and behaviors during the acute phase of the disease. All 15 of these patients experienced psychosis and had suicidal ideation with intention. Three patients engaged in preparatory behaviors and seven carried out suicidal self-directed violence. Psychotic depression and impulsivity were more frequent among those patients with suicidal thoughts and behaviors than among those without any form of suicidality. Four patients engaged in self-directed violence during hospitalization. Remission was sustained in 14 of 15 patients, with suicidal ideation and self-directed violence persisting during follow-up in only one patient.

CONCLUSIONS

Suicidal thoughts and behaviors are not uncommon during the acute phase of ANMDARE. On the basis of our sample, the persistence of these features after immunotherapy is rare but may be observed. A targeted assessment of suicidal risk should be strongly considered in this population.

Anticipated suicidal and death ideation in response to an imagined dementia diagnosis: A qualitative study

Alzheimer's disease and related dementias are prevalent, highly impactful, and feared diagnoses. A mixed methods study using semi-structured interviews was conducted to clarify causes of dementia-related anxiety. Fifty community-dwelling adults aged 58 to 89 (M = 70.92, SD = 6.08) were recruited from a university participant registry and Memory Clinic; none had dementia diagnoses. Analyses revealed that 42% (n = 21) of participants anticipated suicidal or death ideation if diagnosed with dementia. Among participants endorsing anticipated suicidal or death ideation, responses ranged from active, specific plans, including interest in physician-assisted suicide, to more passive wishes to hasten death rather than continue to live with dementia. Within reports of both anticipated suicidal and death ideation, three subthemes emerged. Participants reported concerns about becoming a burden to others, the devaluation of life/loss of self with dementia, and the desire for (and anticipated thwarting of) personal control as factors contributing to their anticipated responses to a dementia diagnosis. Statements of anticipated suicidal and death ideation were contingent on a dementia diagnosis and may reflect errors in affective forecasting. Nevertheless, given the prevalence of dementias and older adults' elevated rates of suicide, the intersection of these two public health issues warrants greater attention.

Association between SARS-CoV-2 infection and self-harm: Danish nationwide register-based cohort study

BACKGROUND

Case studies have linked SARS-CoV-2 infection to suicidal behaviour. However, conclusive evidence is lacking.

AIMS

To examine whether a history of SARS-CoV-2 infection or SARS-CoV-2-related hospital admission was associated with self-harm in the general population and in high-risk groups.

METHOD

A cohort design was applied to nationwide data on all people aged ≥15 years and living in Denmark between 27 February 2020 and 15 October 2021. Exposure was identified as having had a positive SARS-CoV-2 PCR test, and further assessed as SARS-CoV-2-related hospital admission. Rates of probable self-harm were examined using adjusted incidence rate ratios (aIRRs). The following subgroups were identified: (a) lower educational level, (b) chronic medical conditions, (c) disability pension, (d) mental disorders, (e) substance use disorders, and history of (f) homelessness and (g) imprisonment.

RESULTS

Among 4 412 248 included individuals, 260 663 (5.9%) had tested positive for SARS-CoV-2. Out of 5453 individuals presenting with self-harm, 131 (2.4%) had been infected. Individuals with a history of a positive SARS-CoV-2 test result had an aIRR for self-harm of 0.86 (95% CI 0.72-1.03) compared with those without. High rates were found after a SARS-CoV-2-related hospital admission (aIRR = 7.68; 95% CI 5.61-10.51) or a non-SARS-CoV-2-related admission (aIRR = 10.27; 95% CI 9.65-10.93) versus non-infected and not admitted. In sensitivity analyses with a more restrictive definition of self-harm, a positive PCR test was associated with lower rates of self-harm.

CONCLUSIONS

Individuals with a PCR-confirmed SARS-CoV-2 infection did not have higher rates of self-harm than those without. Hospital admission in general, rather than being SARS-CoV-2 positive. seemed to be linked to elevated rates of self-harm.

Predicting suicide attempts among people with diabetes using a large multicenter electronic health records dataset

OBJECTIVE

People with diabetes have a higher risk of suicidal behaviors than the general population. However, few studies have focused on understanding this relationship. We investigated risk factors and predicted suicide attempts in people with diabetes using the Least Absolute Shrinkage and Selection Operator (LASSO) regression.

METHOD

Data was retrieved from Cerner Real-World Data™ and included over 3 million diabetes patients in the study. Least absolute shrinkage and selection operator regression was applied to identify associated factors. Gender-, diabetes-type-, and depression-specific LASSO regression models were analyzed.

RESULTS

There were 7764 subjects diagnosed with suicide attempts with an average age of 45. We found risk factors for suicide attempts in diabetes patients, such as being an American Indian or Alaska Native (β = 0.637), atypical agents (β = 0.704), benzodiazepines (β = 0.784), and antihistamines (β = 0.528). Amyotrophy had a negative coefficient for suicide attempts in males with diabetes (β = -2.025); in contrast, it had a positive coefficient in females with diabetes (β = 3.339). Using MAOI had a negative coefficient for suicide attempts in T1DM patients (β = -7.304). Aged less than 20 had a positive coefficient for suicide attempts in depressed (β = 2.093) and non-depressed patients with diabetes (β = 1.497). The LASSO model had 94.4% AUC and 87.4% F1 score.

CONCLUSIONS

To our knowledge, this is the first study using LASSO regression to identify risk factors for suicide attempts and diabetes. The shrinkage technique successfully reduced the number of variables in the model to improve overfitting. Further research is needed to study cause-and-effect relationships. The results may help providers identify high-risk groups of suicide attempters among diabetes patients.

Living with dementia: Why I am thinking of 'death'

BACKGROUND AND AIMS

Dementia is recognized globally as a massive burden on public health and wider society. It is a major cause of disability and mortality amongst older people. China has the largest population of people with dementia worldwide, accounting for approximately 25% of the entire global population of people with dementia. The study investigated the perceived experiences of care giving and care receiving in China, with one area identified in the data concerning the extent to which the participants discussed death. The research also explored the meaning of living with dementia in modern China, where the economy, demography and culture are rapidly changing.

METHOD

The qualitative approach of interpretative phenomenological analysis was used for this study. Semi-structured interviews were used for data collection.

FINDING

The paper reports on one specific finding concerning death as a way out of the situation that participants found themselves in.

CONCLUSION

The study described and interpreted one of the specific issues, 'death', in the participants' narratives. This finding reflects how psychological and social factors, such as stress, social support, healthcare cost, caring burden and medical practice have created the participants' thoughts of 'wishing to die' and the reasons why they believe 'death is a way to reduce burden'. It calls for an understanding, supportive social environment and a reconsideration of a culturally and economically appropriate family-based care system.

Depression in Major Neurodegenerative Diseases and Strokes: A Critical Review of Similarities and Differences among Neurological Disorders

Depression and anxiety are highly prevalent in most neurological disorders and can have a major impact on the patient's disability and quality of life. However, mostly due to the heterogeneity of symptoms and the complexity of the underlying comorbidities, depression can be difficult to diagnose, resulting in limited recognition and in undertreatment. The early detection and treatment of depression simultaneously with the neurological disorder is key to avoiding deterioration and further disability. Although the neurologist should be able to identify and treat depression initially, a neuropsychiatry team should be available for severe cases and those who are unresponsive to treatment. Neurologists should be also aware that in neurodegenerative diseases, such as Alzheimer's or Parkinson's, different depression symptoms could develop at different stages of the disease. The treatment options for depression in neurological diseases include drugs, cognitive-behavioral therapy, and somatic interventions, among others, but often, the evidence-based efficacy is limited and the results are highly variable. Here, we review recent research on the diagnosis and treatment of depression in the context of Alzheimer's disease, Parkinson's disease, and strokes, with the aim of identifying common approaches and solutions for its initial management by the neurologist.

Association of intellectual disability with overall and type-specific cardiovascular diseases: a population-based cohort study in Denmark

BACKGROUND

Individuals with mental health problems have been shown to have an increased risk of cardiovascular disorder (CVD), but little is known about the risk of early-onset CVD among those with intellectual disability. We aimed to investigate the association between intellectual disability and subsequent CVD, taking into consideration the severity of intellectual disability and neurodevelopmental and neurologic comorbidity.

METHODS

This population-based cohort study used individual-level linked data from Danish national health registries. Participants were all live-born singletons born in Denmark during 1978-2016 (n = 2,288,393). Follow-up began from birth and continued until the onset of CVD, death, emigration, or December 31, 2018, whichever came first. Clinical diagnosis of any CVD or type-specific CVDs was identified in the Danish National Patient Register. Time-varying Cox regression analyses were used to estimate the hazard ratio (HR) of intellectual disability associated with overall and type-specific CVDs.

RESULTS

A total of 11,954 individuals received a diagnosis of intellectual disability (7434 males and 4520 females). During a median follow-up time of 18.5 years (interquartile range, 18.1 years), 652 individuals with intellectual disability (5.5%) received a diagnosis of CVD (incidence rate, 2.4 per 1000 person-years), compared with 78,088 (3.4%) CVD cases in individuals without intellectual disability (incidence rate, 1.9 per 1000 person-years), corresponding to a HR of 1.24 (95% CI, 1.15-1.34). Increased risks of CVD were similar in both childhood (HR, 1.24; 95% CI, 1.08-1.43) and early adulthood (HR, 1.25; 95% CI, 1.14-1.38). For type-specific CVDs, intellectual disability was significantly associated with cerebrovascular disease (HR, 2.50; 95% CI, 2.02-3.10), stroke (HR, 2.20; 95% CI, 1.69-2.86), heart failure (HR, 3.56; 95% CI, 2.37-5.35), hypertensive disease (HR, 1.30; 95% CI, 1.22-1.39), and deep vein thrombosis (HR, 2.10; 95% CI, 1.60-2.75). Stratified HRs of overall CVD were 1.14 (95% CI, 1.01-1.30) for borderline/mild intellectual disability, 1.25 (95% CI, 1.01-1.54) for moderate intellectual disability, and 1.91 (95% CI, 1.47-2.48) for severe/profound intellectual disability. After the exclusion of individuals with neurodevelopmental and neurologic comorbidity, intellectual disability remained significantly associated with increased risks of CVD.

CONCLUSIONS

Individuals with intellectual disability had increased risks of early-onset CVD, in particular, for cerebrovascular disease, stroke, heart failure, and deep vein thrombosis, and the risks also increased with the severity of intellectual disability. Our findings highlight the awareness of increased risks of CVD in intellectual disability patients.

Risk of suicide after diagnosis of severe physical health conditions: A retrospective cohort study of 47 million people

BACKGROUND

The diagnosis of a severe physical health condition can cause psychological distress and lead to severe depression. The association between severe physical health conditions and the risk of suicide, and how the risk of suicide changes in the months following diagnosis, are not clear.

METHODS

We estimated whether a diagnosis of severe physical health conditions is associated with an increase in the risk of death by suicide using a dataset based on the 2011 Census linked to hospital records and death registration records covering 47,354,696 people alive on 1 January 2017 in England. Patients diagnosed with a low-survival cancer, chronic ischaemic heart disease, chronic obstructive pulmonary disease, or degenerative neurological condition were matched to individuals using socio-demographic characteristics from the Census. Using the Aalen-Johansen estimator, we estimated the cumulative incidence of death by suicide occurring between 1 January 2017 and 31 December 2021 (registered by 31 December 2021) in patients and matched controls, adjusted for other potential confounders using inverse probability weighting.

FINDINGS

Diagnosis of severe conditions was associated with an increased risk of dying by suicide. One year after diagnosis, the rate of suicide was 21.6 (95% confidence intervals: 14.9-28.4, number of events (N): 39) per 100,000 low-survival cancer patients compared to 9.5 (5.6-14.6, N:16) per 100,000 matched controls. For COPD patients, the one-year suicide rate was 22.4 (19.4-25.5, N:208) per 100,000 COPD patients (matched controls: 10.6, 8.3-13.0, N:85), for ischaemic heart disease 16.1 (14.1-18.2, N:225) per 100,000 patients (matched controls: 8.8, 7.1-10.4, N:128), for degenerative neurological conditions 114.5 (49.6-194.7, N:11) per 100,000 patients. The increase in risk was more pronounced in the first six months after diagnosis or first treatment.

INTERPRETATION

A diagnosis of severe physical illness is associated with higher suicide risk. The interaction of physical and mental illness emphasises the importance of collaborative physical and mental health care in these patients.

Suicidal ideation and intentional self-inflicted injury in autism spectrum disorder and intellectual disability: An examination of trends in youth emergency department visits in the United States from 2006 to 2014

LAY ABSTRACT

Youth suicide is a major problem in the United States and globally, but little is known about suicide risk in autistic youth and youth with intellectual disability specifically. Using data from the National Emergency Department Sample, which is the largest database of emergency department visits in the United States, we found that emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis were more common in autistic youth and youth with intellectual disability than in youth without these diagnoses (i.e. the comparison group). This was true when examining both suicidal ideation diagnoses and intentional self-inflicted injury diagnoses at emergency department visits. In addition, the number of emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis increased more from 2006 to 2014 in autistic youth and youth with intellectual disability compared with the comparison group. We also found both similarities and differences when examining factors, such as age, sex, and co-occurring mental health conditions, related to emergency department visits with a suicidal ideation or intentional self-inflicted injury diagnosis across groups that may be helpful for understanding suicide risk. It is urgent that we improve our understanding, assessment, and treatment of suicidality and self-harm in these groups through more research and clinical efforts.

The manifestation of affective symptoms in multiple sclerosis and discussion of the currently available diagnostic assessment tools

INTRODUCTION

In addition to physical and cognitive symptoms, patients with multiple sclerosis (MS) have an increased risk of experiencing mental health problems.

METHODS

This narrative review provides an overview of the appearance and epidemiology of affective symptoms in MS such as depression, anxiety, bipolar disorder, euphoria, and pseudobulbar affect. Furthermore, the association between affective symptoms and quality of life and the currently used diagnostic instruments for assessing these symptoms are considered whereby relevant studies published between 2009 and 2021 were included in the review.

RESULTS

Patients with mild and moderate disability more frequently reported severe problems with depression and anxiety than severe mobility problems. Apart from the occurrence of depression, little is known about the association of other affective symptoms such as anxiety, bipolar disorder, euphoria, and pseudobulbar affect and subsyndromal symptoms, which fail to meet the diagnostic criteria but are nevertheless a significant source of distress. Although there are a few recommendations in the research to perform routine screenings for diagnosable affective disorders, a standardized diagnostic procedure to assess subsyndromal symptoms is still lacking. As the applied measurements are diverse and show low accuracy to detect these symptoms, patients who experience affective symptoms are less likely to be identified.

DISCUSSION

In addition to the consideration of definite psychiatric diagnoses, there is an unmet need for a common definition and assessment of disease-related affective symptoms in MS. Future studies should focus on the improvement and standardization of a common diagnostic procedure for subsyndromal affective symptoms in MS to enable integrated and optimal care for patients.

Suicidality and epilepsy: A systematic review and meta-analysis

Background

We aimed to evaluate the association between epilepsy and suicidality, including suicidal ideation, attempts and completed suicide.

Methods

We systematically searched PubMed, Embase, Cochrane Online Library, and Clinicaltrials.gov from 1946 to June 21, 2021 and assessed the quality of the studies using the Newcastle-Ottawa Scale. We calculated the pooled OR and the crude rate for suicidal ideation, suicide attempts and completed suicide in patients with epilepsy (PWE).

Results

We screened 2,786 studies and included 88 articles with 1,178,401 PWE and 6,900,657 participants as controls. Search terms included epilepsy and suicide. The pooled rates of suicidal ideation, suicide attempts and completed suicide in PWE were 19.73% (95% CI: 17.00-22.62%), 5.96% (95% CI: 4.82-7.20%), and 0.24% (95% CI: 0.11-0.42%), respectively. Compared to the control group, PWE were at a significantly higher risk of total suicidality (pooled OR, 2.60; 95%: 2.13-3.18), including suicidal ideation (pooled OR, 2.70; 95% CI, 2.21-3.30), suicide attempts (pooled OR, 2.74; 95% CI, 2.08-3.61) and completed suicide (pooled OR, 2.36; 95% CI, 1.45-3.83). Subgroup analyses showed significant differences in the subgroups of the measurement of suicidality.

Conclusion

The rate of suicidal ideation, suicide attempts and completed suicide in PWE were about 19.73, 5.96, and 0.24%. And there was an increased risk of suicidality in PWE especially temporal lobe epilepsy and drug-resistant epilepsy. Clinicians need to be aware of this risk in PWE with early identification and prevention at the time of diagnosis.Protocol Registration: PROSPERO CRD42021278220.

Risk of Suicide After Dementia Diagnosis

Importance

Patients with dementia may be at an increased suicide risk. Identifying groups at greatest risk of suicide would support targeted risk reduction efforts by clinical dementia services.

Objectives

To examine the association between a dementia diagnosis and suicide risk in the general population and to identify high-risk subgroups.

Design, Setting, and Participants

This was a population-based case-control study in England conducted from January 1, 2001, through December 31, 2019. Data were obtained from multiple linked electronic records from primary care, secondary care, and the Office for National Statistics. Included participants were all patients 15 years or older and registered in the Office for National Statistics in England with a death coded as suicide or open verdict from 2001 to 2019. Up to 40 live control participants per suicide case were randomly matched on primary care practice and suicide date.

Exposures

Patients with codes referring to a dementia diagnosis were identified in primary care and secondary care databases.

Main Outcomes and Measures

Odds ratios (ORs) were estimated using conditional logistic regression and adjusted for sex and age at suicide/index date.

Results

From the total sample of 594 674 patients, 580 159 (97.6%) were controls (median [IQR] age at death, 81.6[72.0-88.4] years; 289 769 male patients [50.0%]), and 14 515 (2.4%) died by suicide (median [IQR] age at death, 47.4 [36.0-59.7] years; 10 850 male patients [74.8%]). Among those who died by suicide, 95 patients (1.9%) had a recorded dementia diagnosis (median [IQR] age at death, 79.5 [67.1-85.5] years; median [IQR] duration of follow-up, 2.3 [1.0-4.4] years). There was no overall significant association between a dementia diagnosis and suicide risk (adjusted OR, 1.05; 95% CI, 0.85-1.29). However, suicide risk was significantly increased in patients diagnosed with dementia before age 65 years (adjusted OR, 2.82; 95% CI, 1.84-4.33), in the first 3 months after diagnosis (adjusted OR, 2.47; 95% CI, 1.49-4.09), and in patients with dementia and psychiatric comorbidity (adjusted OR, 1.52; 95% CI, 1.21-1.93). In patients younger than 65 years and within 3 months of diagnosis, suicide risk was 6.69 times (95% CI, 1.49-30.12) higher than in patients without dementia.

Conclusions and Relevance

Diagnostic and management services for dementia, in both primary and secondary care settings, should target suicide risk assessment to the identified high-risk groups.

Risk of self-harm in post TIA patients: A population-based cohort study

OBJECTIVE

The purpose of this study was to determine whether individuals who have experienced a transient ischemic attack (TIA) have an increased risk of self-harm behaviors.

METHODS

In this matched cohort study, we reviewed the electronic health records of all patients admitted for any reason to Hong Kong public hospitals between January 1, 1993, and December 31, 2019. We selected a post-TIA cohort consisting of 37,356 patients and a comparison cohort comprising 37,352 subjects. All participants enrolled in this study were followed up until a diagnosis of self-harm, death from other causes, or the end of 2020, whichever occurred first. Univariate Cox proportional hazards regression models were used to calculate the risk of self-harm since the onset of TIA.

RESULTS

Throughout the 27-year study period, the number of individuals exhibiting self-harm behavior in the TIA and comparison groups was 1031 (2.76%) and 512 (1.37%), respectively. The TIA group had a higher proportion of subjects with self-harm (χ² = 178, p < .001). The incidence rates of self-harm were 33.94 and 19.27 per 10,000 person-years in TIA patients and comparators, respectively. Compared with the comparators, the adjusted hazard ratio for self-harm in TIA patients was 1.63 (95% confidence interval, 1.46-1.82).

CONCLUSIONS

TIA is associated with an increased risk of self-harm. Healthcare professionals should help identify patients at heightened risk and provide efficient and targeted prevention strategies for this population.

Suicide and Epilepsy

PURPOSE OF REVIEW

Epilepsy has a bidirectional association with suicidality, and epilepsy patients are at much higher risk for suicide than the general population. This article reviews the recent literature on suicide risk factors, assessments, and management as they pertain specifically to suicidality in people with epilepsy, a population that requires unique considerations.

RECENT FINDINGS

Risk factors for suicidality include younger age (independent of comorbid psychiatric disorders), poor social support, psychiatric comorbidity (depression, anxiety, obsessive-compulsive symptoms, and alcohol use), and epilepsy-related factors (more frequent seizures, temporal lobe epilepsy, and drug-resistant epilepsy). Most clinicians agree with the need for addressing suicidality; however, there is inconsistency in the approach to caring for these patients. An example neurology clinic-based approach is outlined. Although PWE are at risk for suicide and risk factors have been characterized, care gaps remain. Screening strategies may help close these gaps.

Suicidality in Patients With Epilepsy: Why Should Neurologists Care?

Suicidality is a relatively common comorbidity in patients with epilepsy (PWE). Population-based studies have revealed lifetime prevalence rates of 25% of suicidal ideation (SI). In addition, PWE without comorbid psychiatric disorders has two to three higher risk of committing suicide and this risk increases by 12- to 32-fold in the presence of various psychiatric disorders. Risk factors are multiple and include socio-demographic, genetic, age and gender, and psychiatric comorbidities. Among the latter, mood, anxiety, and psychotic disorders have been found to be common risk factors for suicidality in PWE, but iatrogenic causes resulting from pharmacotherapy with antiseizure drugs or epilepsy surgery can also cause SI and behavior. Suicidality and epilepsy have a complex bidirectional relation, whereas PWE are at increased risk of suicidality and vice-versa. Common pathogenic mechanisms operant in both conditions may explain this bidirectional relation. SI can be easily identified in outpatient epilepsy clinics with screening instruments and can be treated and thus prevent its escalation to suicidal attempts and completed suicide. The aim of this manuscript is to review these data in detail.

Association between new-onset Parkinson's disease and suicide risk in South Korea: a nationwide cohort study

BACKGROUND

Parkinson's disease (PD) is an increasingly common neurodegenerative disease in an aging society. Whether PD is associated with an increased suicide risk is unclear. Thus, we investigated the effect of new-onset PD on suicide.

METHODS

Using the National Health Insurance Service Senior Sample Cohort of South Korea, 17,143 incident PD patients and 17,143 risk set controls, matched by propensity score, were selected for follow-up. The incidence rate of suicide and 95% confidence interval (CI) were calculated based on a generalized linear model of the Poisson distribution. Effect sizes were expressed as hazard ratios (HRs) using the Cox proportional hazards model with a robust variance estimator that incorporated clustering within matched pairs.

RESULTS

The incidence rate of suicide was 206.7 cases per 100,000 person-years (95% CI, 172.8-246.9) among the PD cohort. Compared to the matched controls, patients with PD were 2.64 times (HR, 2.64; 95% CI, 1.31-5.30) more likely to commit suicide during the first 180 days of follow-up and 2.47 times (HR, 2.47; 95% CI, 1.42-4.28) within the first 365 days of follow-up. During the entire follow-up period, patients with PD were 2.26 times more likely to commit suicide than were their matched controls (HR, 2.26; 95% CI, 1.67-3.06).

CONCLUSION

Our findings indicated an increased risk of suicide in patients with new-onset PD, regardless of the period after diagnosis. Incorporating mental health care with social and environmental interventions into primary care and PD-specialized care can help reduce suicide risk in people with PD, improving suicide prevention, identification, and risk assessment.

Intra-Cardiac Arrest Transport and Survival from Out-of-Hospital Cardiac Arrest: A Nationwide Observational Study

AIM

To assess whether intra-cardiac arrest transport as compared to continued on-scene resuscitation was associated with improved clinical outcomes among out-of-hospital cardiac arrest patients in Denmark.

METHODS

This was an observational study using data from population-based registries in Denmark. Adults (aged ≥18 to ≤65 years) with an out-of-hospital cardiac arrest attended by Emergency Medical Services (EMS) between 2016 and 2018 were included. The primary outcome was survival to 30 days. Time-dependent propensity score matching was used to match patients transported to the hospital within 20 minutes of EMS arrival to patients with assumed on-scene resuscitation (with or without subsequent intra-cardiac arrest transport) at risk of being transported within the same minute.

RESULTS

The full cohort included 2,873 cardiac arrests. The median age was 56 (quartiles: 48 to 62) years, 1987 (69%) were male, and 104 (4%) were transported within 20 minutes. A total of 87 transported patients were matched to 87 patients at risk of being transported based on the propensity score. Although not reaching statistical significance, in comparison with on-scene resuscitation, intra-cardiac arrest transport was associated with increased survival to 30 days (risk ratio, 1.55; 95%CI, 0.99 to 2.44; P = 0.06). Similar associations were observed for return of spontaneous circulation and survival to one year.

CONCLUSIONS

Among patients aged 18 to 65 years, intra-cardiac arrest transport was associated with a non-significant increase in survival within 20 minutes of EMS on-scene arrival. However, the results did not eliminate the potential for bias and the results should be interpreted carefully.

Risk of mortality from suicide in patients with Huntington's disease is increased compared to the general population in England

Objective

To examine the relative risk of suicide mortality in patients with Huntington’s disease (HD).

Methods

A case–control study design was used. We used linked electronic records from primary care, secondary care and Office for National Statistics from England from 2001 through 2019. Controls were matched to cases by general practice and suicide date. Odds ratios (ORs) were adjusted for gender and age at suicide/index date.

Results

Data were available for 594,674 individuals. Patients with HD who died from suicide were significantly younger at time of death than patients with HD who died from causes other than suicide (p < 0.001). The adjusted OR for HD was 9.2 (95% confidence intervals, CI 4.9–17.4) compared to those without HD. The increase in risk was higher amongst the younger age group who were ≤ 45.8 years at suicide/index date (OR 54.5, 95% CI 10.8–276.1).

Conclusion

The markedly elevated suicide risk in patients with HD suggests that implementation of suicide risk assessment may improve survival in individuals with these diseases, especially in younger patients.

Suicidal ideation in dementia: associations with neuropsychiatric symptoms and subtype diagnosis

OBJECTIVES

To investigate factors associated with suicidal ideation (SI) around the time of dementia diagnosis. We hypothesised relatively preserved cognition, co-occurring physical and psychiatric disorders, functional impairments, and dementia diagnosis subtype would be associated with a higher risk of SI.

DESIGN

Cross-sectional study using routinely collected electronic mental healthcare records.

SETTING

National Health Service secondary mental healthcare services in South London, UK, serving a population of over 1.36 million residents.

PARTICIPANTS

Patients who received a diagnosis of dementia (Alzheimer's, vascular, mixed Alzheimer's/vascular, or dementia with Lewy bodies) between 1 Nov 2007-31 Oct 2021: 18,252 people were identified during the observation period.

MEASUREMENTS

A natural language processing algorithm was used to identify recorded clinician recording of SI around the time of dementia diagnosis. Sociodemographic and clinical characteristics were also measured around the time of diagnosis. We compared people diagnosed with non-Alzheimer's dementia to those with Alzheimer's and used statistical models to adjust for putative confounders.

RESULTS

15.1% of patients had recorded SI, which was more common in dementia with Lewy bodies compared to other dementia diagnoses studied. After adjusting for sociodemographic and clinical factors, SI was more frequent in those with depression and dementia with Lewy bodies and less common in those with impaired activities of daily living and in vascular dementia. Agitated behavior and hallucinations were not associated with SI in the final model.

CONCLUSIONS

Our findings highlight the importance of identifying and treating depressive symptoms in people with dementia and the need for further research into under-researched dementia subtypes.

Suicide risk in first year after dementia diagnosis in older adults

INTRODUCTION

Receiving a diagnosis of Alzheimer's disease or related dementias (ADRD) can be a pivotal and stressful period. We examined the risk of suicide in the first year after ADRD diagnosis relative to the general geriatric population.

METHODS

We identified a national cohort of Medicare fee-for-service beneficiaries aged ≥ 65 years with newly diagnosed ADRD (n = 2,667,987) linked to the National Death Index.

RESULTS

The suicide rate for the ADRD cohort was 26.42 per 100,000 person-years. The overall standardized mortality ratio (SMR) for suicide was 1.53 (95% confidence interval [CI] = 1.42, 1.65) with the highest risk among adults aged 65 to 74 years (SMR = 3.40, 95% CI = 2.94, 3.86) and the first 90 days after ADRD diagnosis. Rural residence and recent mental health, substance use, or chronic pain conditions were associated with increased suicide risk.

DISCUSSION

Results highlight the importance of suicide risk screening and support at the time of newly diagnosed dementia, particularly for patients aged < 75 years.

Spotlight on non-motor symptoms and Covid-19

The Coronavirus Disease 2019 (Covid-19) pandemic has profoundly affected the quality of life (QoL) and health of the general population globally over the past 2 years, with a clear impact on people with Parkinson's Disease (PwP, PD). Non-motor symptoms have been widely acknowledged to hold a vital part in the clinical spectrum of PD, and, although often underrecognized, they significantly contribute to patients' and their caregivers' QoL. Up to now, there have been numerous reports of newly emerging or acutely deteriorating non-motor symptoms in PwP who had been infected by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), while some of these symptoms, like fatigue, pain, depression, anxiety and cognitive impairment, have also been identified as part of the long-COVID syndrome due to their persistent nature. The subjacent mechanisms, mediating the appearance or progression of non-motor symptoms in the context of Covid-19, although probably multifactorial in origin, remain largely unknown. Such mechanisms might be, at least partly, related solely to the viral infection per se or the lifestyle changes imposed during the pandemic, as many of the non-motor symptoms seem to be prevalent even among Covid-19 patients without PD. Here, we summarize the available evidence and implications of Covid-19 in non-motor PD symptoms in the acute and chronic, if applicable, phase of the infection, with a special reference on studies of PwP.

Psychiatric comorbidity and risk of premature mortality and suicide among those with chronic respiratory diseases, cardiovascular diseases, and diabetes in Sweden: A nationwide matched cohort study of over 1 million patients and their unaffected siblings

BACKGROUND

Persons with noncommunicable diseases have elevated rates of premature mortality. The contribution of psychiatric comorbidity to this is uncertain. We aimed to determine the risks of premature mortality and suicide in people with common noncommunicable diseases, with and without psychiatric disorder comorbidity.

METHODS AND FINDINGS

We used nationwide registries to study all individuals born in Sweden between 1932 and 1995 with inpatient and outpatient diagnoses of chronic respiratory diseases (n = 249,825), cardiovascular diseases (n = 568,818), and diabetes (n = 255,579) for risks of premature mortality (≤age 65 years) and suicide until 31 December 2013. Patients diagnosed with either chronic respiratory diseases, cardiovascular diseases, or diabetes were compared with age and sex-matched population controls (n = 10,345,758) and unaffected biological full siblings (n = 1,119,543). Comorbidity with any psychiatric disorder, and by major psychiatric categories, was examined using diagnoses from patient registers. Associations were quantified using stratified Cox regression models that accounted for time at risk, measured sociodemographic factors, and unmeasured familial confounders via sibling comparisons. Within 5 years of diagnosis, at least 7% (range 7.4% to 10.8%; P < 0.001) of patients with respiratory diseases, cardiovascular diseases, or diabetes (median age at diagnosis: 48 to 54 years) had died from any cause, and 0.3% (0.3% to 0.3%; P < 0.001) had died from suicide, 25% to 32% of people with these medical conditions had co-occurring lifetime diagnoses of any psychiatric disorder, most of which antedated the medical diagnosis. Comorbid psychiatric disorders were associated with higher all-cause mortality (15.4% to 21.1%) when compared to those without such conditions (5.5% to 9.1%). Suicide mortality was also elevated (1.2% to 1.6% in comorbid patients versus 0.1% to 0.1% without comorbidity). When we compared relative risks with siblings without noncommunicable diseases and psychiatric disorders, the comorbidity with any psychiatric disorder was associated with substantially increased mortality rates (adjusted HR range: aHRCR = 7.2 [95% CI: 6.8 to 7.7; P < 0.001] to aHRCV = 8.9 [95% CI: 8.5 to 9.4; P < 0.001]). Notably, comorbid substance use disorders were associated with a higher mortality rate (aHR range: aHRCR = 8.3 [95% CI: 7.6 to 9.1; P < 0.001] to aHRCV = 9.9 [95% CI: 9.3 to 10.6; P < 0.001]) than depression (aHR range: aHRCR = 5.3 [95% CI: 4.7 to 5.9; P < 0.001] to aHRCV = 7.4 [95% CI: 7.0 to 7.9; P < 0.001]), but risks of suicide were similar for these 2 psychiatric comorbidities. One limitation is that we relied on secondary care data to assess psychiatric comorbidities, which may have led to missing some patients with less severe comorbidities. Residual genetic confounding is another limitation, given that biological full siblings share an average of half of their cosegregating genes. However, the reported associations remained large even after adjustment for shared and unmeasured familial confounders.

CONCLUSIONS

In this longitudinal study of over 1 million patients with chronic health diseases, we observed increased risks of all-cause and suicide mortality in individuals with psychiatric comorbidities. Improving assessment, treatment, and follow-up of people with comorbid psychiatric disorders may reduce the risk of mortality in people with chronic noncommunicable diseases.

[Why do we require clinical guidelines for suicide prevention?]

Trotz der Relevanz des Themas Suizidalität und gut bekannter Risikofaktoren gibt es bisher keine deutsche Leitlinie zur Suizidalität im Erwachsenenalter. In diesem Beitrag werden zunächst die Geschichte und die Hintergründe der Arbeit mit Leitlinien beschrieben. Der aktuelle Stand der Leitlinien für psychische Erkrankungen in Deutschland wird dargestellt und auf suizidpräventive Inhalte hin untersucht. Die Notwendigkeit evidenzbasierter Suizidprävention und einer spezifischen Leitlinie zur Suizidprävention bei Erwachsenen wird diskutiert.

Nur durch gezielte Suizidpräventionsstrategien und Interventionen für die jeweiligen Risikogruppen und unter Beachtung von Alters- und Geschlechtsspezifität kann für alle Betroffenen eine flächendeckende, gut erreichbare, bedarfs- und versorgungsgerechte, finanzierbare sowie nachhaltige medizinische Versorgung auf einem hohen Niveau sichergestellt werden. Dies gilt für den ambulanten und den stationären Bereich sowie für deren Schnittstellen. Bei Suizidalität handelt es sich um ein diagnoseübergreifendes, in unterschiedlichen Versorgungskontexten auftretendes Syndrom mit komplexem Behandlungsbedarf, weshalb intersektorale und multiprofessionelle Aspekte in einer entsprechenden Leitlinie besonders zu adressieren sind. Wissenschaftliche Evidenz und interdisziplinärer Konsens unter Expertinnen und Experten zum Umgang mit suizidalem Verhalten in der medizinischen Versorgung können dazu beitragen, Morbidität und Mortalität im Zusammenhang mit Suizidalität zu reduzieren. Im August 2021 wurde die Finanzierung einer S3-Leitlinie „Umgang mit Suizidalität“ vom Innovationsfonds des Gemeinsamen Bundesausschusses bewilligt.

Robin's Wish and the Complex Causal Web of Death by Suicide

The documentary film Robin's Wish aims to reclaim the media scrutiny around Robin Williams' death, fixating on causation being solely attributed to a postmortem diagnosis of which Williams was unaware-Lewy Body Dementia. The film and other sources as well defined and animated the view that Williams' death by suicide was fully a result of this medical condition, dismissing any possible role for mental disorders. The need to distance from mental disorders can have a palpable undercurrent of stigmatization of them; the documentary missed the opportunity to make its point and simultaneously build allyship with others who have lost someone to suicide who were clearly battling a mental disorder. In this context, we emphasize the importance of looking at causation mediationally (e.g., a neurological condition triggering a major depressive episode culminating, in turn, in death by suicide). Only through encompassing all elements and complexities of the human spirit and condition can we appropriately pay tribute to those we have lost to suicide and simultaneously de-stigmatize mental disorders.

[Genetic counseling and predictive testing for hereditary neuromuscular diseases]

Recent progress in genetic analysis can provide a precision diagnosis for many hereditary neuromuscular diseases in daily practice. Moreover, disease-modifying therapies such as nucleic acid medicine for patients with several neuromuscular diseases (i.e., hereditary ATTR amyloidosis, spinal muscular atrophy, and Duchenne muscular dystrophy) have been approved in Japan. For all neurologists, knowledge and practical skills of genetic counseling, especially predictive testing, will increase in importance. To promote personalized medicine for patients with neuromuscular diseases and their families, it is necessary to develop of genetic counseling systems, including nurturing genetic professionals.

Wearables for Neurologic Conditions: Considerations for Our Patients and Research Limitations

Purpose of Review

In 2019, over 50 million Americans were expected to use wearables at least monthly. The technologies have varied capabilities, with many designed to monitor health conditions. We present a narrative review to raise awareness of wearable technologies that may be relevant to the field of neurology. We also discuss the implications of these wearables for our patients and briefly discuss issues related to researching new wearable technologies.

Recent Findings

There are a variety of wearables for neurologic conditions, e.g., stroke (for potential arrhythmia capture), epilepsy, Parkinson disease, and sleep. Research is being performed to capture the risk of neuropsychiatric relapse. However, data are limited and adherence to these wearables is often poorly studied.

Summary

The care of neurology patients may ultimately be improved with the use of wearable technologies. More research needs to examine efficacy and implementation strategies.
