Extreme behavioural and psychological symptoms of dementia: a case study

BACKGROUND

The seven tiered behavioural and psychological symptoms of dementia (BPSD) model of service delivery has been used by inpatient units. The classification of each tier is broadly defined and not always agreed upon by clinicians. The case study uses novel approach by combining the BPSD classification criteria with clinical presentation to identify the clinical characteristics of the case and match these characteristics against the BPSD classification. This process was enhanced by using case specific measures such as the Neuropsychiatric Inventory (NPI) and Cohen Mansfield Agitation Inventory (CMAI) scales and key clinical data.

CASE PRESENTATION

A case study of 76 year old male diagnosed with mixed Alzheimer's and Vascular dementia. The clinical presentation of the symptomatology was deemed to be extreme, thus fitting into the seventh tier (Extreme) of the BPSD model of service delivery. The case is considered to fit into the Extreme BPSD category given the high levels of aggression, which were consistently reflected in high scores on NPI and CMAI, as well as long length of inpatient stay (over 3 years). The average number of Pro re nata (PRN) psychotropics medications per month was 56 and seclusion episodes of 6 times per month, with each episode lasting on average 132 min shows severity of behaviours. His level of aggression had resulted in environmental damage and staff injuries.

CONCLUSION

We recommend patient clinical characteristics, relevant hospital data and specific measures should be used to develop consensus around defining and classifying cases into Extreme BPSD.

Clusterization of Behavioral and Psychological Symptoms of Dementia as Assessed by Neuropsychiatric Inventory: A Case Against the Use of Principal Component Analysis

Background

The term Behavioral and Psychological Symptoms of Dementia (BPSD) covers a group of phenomenologically and medically distinct symptoms that rarely occur in isolation. Their therapy represents a major unmet medical need across dementias of different types, including Alzheimer's disease. Understanding of the symptom occurrence and their clusterization can inform clinical drug development and use of existing and future BPSD treatments.

Objective

The primary aim of the present study was to investigate the ability of a commonly used principal component analysis to identify BPSD patterns as assessed by Neuropsychiatric Inventory (NPI).

Methods

NPI scores from the Aging, Demographics, and Memory Study (ADAMS) were used to characterize reported occurrence of individual symptoms and their combinations. Based on this information, we have designed and conducted a simulation experiment to compare Principal Component analysis (PCA) and zero-inflated PCA (ZI PCA) by their ability to reveal true symptom associations.

Results

Exploratory analysis of the ADAMS database revealed overlapping multivariate distributions of NPI symptom scores. Simulation experiments have indicated that PCA and ZI PCA cannot handle data with multiple overlapping patterns. Although the principal component analysis approach is commonly applied to NPI scores, it is at risk to reveal BPSD clusters that are a statistical phenomenon rather than symptom associations occurring in clinical practice.

Conclusions

We recommend the thorough characterization of multivariate distributions before subjecting any dataset to Principal Component Analysis.

Behavioral or neuropsychiatric symptoms of Alzheimer's disease: from psychopathology to pharmacological management

Neuropsychiatric or behavioral symptoms of dementia encompass a series of disorders, such as anxiety, depression, apathy, psychosis, and agitation, all commonly present in individuals living with dementia. While they are not required for the diagnosis of Alzheimer's disease (AD), they are ubiquitously present in all stages of the disease, contributing to negative clinical outcomes, including cognitive decline, functional disability, and caregiver burden. Neuropsychiatric symptoms have been conceptualized not only as risk factors but as clinical markers of decline along the AD spectrum. The concept of "mild behavioral impairment", the behavioral correlate of mild cognitive impairment, has been proposed within this framework. The first steps in the management of behavioral symptoms in AD involve defining the target and investigating potential causes and/or aggravating factors. Once these factors are addressed, non-pharmacological approaches are preferred as first-line interventions. Following the optimization of anticholinesterase treatments, specific pharmacological approaches (e.g., antidepressants, antipsychotics) can be considered weighing potential side effects.

Frequency and imaging correlates of neuropsychiatric symptoms in Progressive Supranuclear Palsy

Neuropsychiatric symptoms are intrinsic to Progressive Supranuclear Palsy (PSP) and a spoonful of studies investigated their imaging correlates. Describe (I) the frequency and severity of neuropsychiatric symptoms in PSP and (II) their structural imaging correlates. Twenty-six PSP patients underwent Neuropsychiatric Inventory (NPI) and brain 3D T1-weighted MRI. Spearman's rho with Bonferroni correction was used to investigate correlations between NPI scores and volumes of gray matter regions. More than 80% of patients presented at least one behavioral symptom of any severity. The most frequent and severe were depression/dysphoria, apathy, and irritability/lability. Significant relationships were found between the severity of irritability and right pars opercularis volume (p < 0.001) as well as between the frequency of agitation/aggression and left lateral occipital volume (p < 0.001). Depression, apathy, and irritability are the most common neuropsychiatric symptoms in PSP. Moreover, we found a relationship between specific positive symptoms as irritability and agitation/aggression and greater volume of the right pars opercularis cortex and lower volume of the left occipital cortex, respectively, which deserve further investigations.

Purinergic signaling in cognitive impairment and neuropsychiatric symptoms of Alzheimer's disease

About 10 million new cases of dementia develop worldwide each year, of which up to 70% are attributable to Alzheimer's disease (AD). In addition to the widely known symptoms of memory loss and cognitive impairment, AD patients frequently develop non-cognitive symptoms, referred to as behavioral and psychological symptoms of dementia (BPSDs). Sleep disorders are often associated with AD, but mood alterations, notably depression and apathy, comprise the most frequent class of BPSDs. BPSDs negatively affect the lives of AD patients and their caregivers, and have a significant impact on public health systems and the economy. Because treatments currently available for AD are not disease-modifying and mainly aim to ameliorate some of the cognitive symptoms, elucidating the mechanisms underlying mood alterations and other BPSDs in AD may reveal novel avenues for progress in AD therapy. Purinergic signaling is implicated in the pathophysiology of several central nervous system (CNS) disorders, such as AD, depression and sleep disorders. Here, we review recent findings indicating that purinergic receptors, mainly the A₁, A_2A, and P2X7 subtypes, are associated with the development/progression of AD. Current evidence suggests that targeting purinergic signaling may represent a promising therapeutic approach in AD and related conditions. This article is part of the Special Issue on "Purinergic Signaling: 50 years".

Effect of Nordic Sensi® Chair on Behavioral and Psychological Symptoms of Dementia in Nursing Homes Residents: A Randomized Controlled Trial

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are present in most people with dementia (PwD), including Alzheimer's disease. There is consensus that non-pharmacological therapies represent the first line of treatment to address BPSD.

OBJECTIVE

We explore the efficacy of the use of a rocking chair (Nordic Sensi® Chair, NSC) in the treatment of BPSD in nursing home residents with moderate and severe dementia.

METHODS

We carried out a 16-week randomized, single-blind, controlled, clinical trial with PwD admitted to nursing homes. Participants were assigned to a treatment group (n = 40) that received three times a week one session per day of 20 minutes in the NSC and a control group (n = 37). The Neuropsychiatric Inventory-Nursing Home (NPI-NH) was used as primary efficacy outcome. Occupational distress for the staff was evaluated using the NPI-NH Occupational Disruptiveness subscale (NPI-NH-OD). Statistical analyses were conducted by means of a Mixed Effects Model Analysis.

RESULTS

Treatment with the NSC was associated with a beneficial effect in most of BPSD, as reflected by differences between the treatment and control group on the NPI-NH total score (mean change score -18.87±5.56 versus -1.74±0.67, p = 0.004), agitation (mean change score -2.32±2.02 versus -0.78±1.44, p = 0.003) and irritability (mean change score -3.35±2.93 versus -1.42±1.31, p = 0.004). The NPI-NH-OD total score also improved the most in the treatment group (mean change score -9.67±7.67 versus -7.66±6.08, p = 0.003).

CONCLUSIONS

The reduction in overall BPSD along with decreased caregiver occupational disruptiveness represent encouraging findings, adding to the potential of nonpharmacological interventions for nursing home residents living with dementia.

Hospital practices and clinical outcomes associated with behavioral symptoms in persons with dementia

BACKGROUND

Hospitalized persons living with dementia (PLWD) often experience behavioral symptoms that challenge medical care.

OBJECTIVE

This study aimed to identify clinical practices and outcomes associated with behavioral symptoms in hospitalized PLWD.

DESIGN

A retrospective cross-sectional study.

SETTINGS AND PARTICIPANTS

The study included PLWD (65+) admitted to one of severe health system hospitals in 2019.

INTERVENTION

Behavioral symptoms were defined as the presence of (1) a psychoactive medication for behavioral symptoms; (2) an order for physical restraints or constant observation; and/or (3) physician documentation of delirium, encephalopathy, or behavioral symptoms.

MAIN OUTCOME AND MEASURES

Associations between behavioral symptoms and patient characteristics and hospital practices (e.g., bladder catheter) were examined. Multivariable logistic/linear regression was used to evaluate the association between behavioral symptoms and clinical outcomes (e.g., mortality).

RESULTS

Of hospitalized PLWD (N = 8637), the average age was 84.5 years (IQR = 79-90), 61.7% were female, 60.1% were white, and 9.4% (n = 833) were Hispanic. Behavioral symptoms were identified in 40.6% (N = 3606) of individuals. Behavioral symptoms were significantly associated with male gender (40.3% vs. 36.9%, p = .001), white race (62.7% vs. 58.3%, p < .001), and residence in a facility prior to admission (26.6% vs. 23.7%, p < .001). Regarding hospital practices, indwelling bladder catheters (11.2% vs. 6.0%, p < .001) and dietary restriction (41.9% vs. 33.8%, p < .001) were associated with behavioral symptoms. In multivariable models, behavioral symptoms were associated with increased hospital mortality (odds ratio [OR]: 1.90, CI95%: 1.57-2.29), length of stay (parameter estimate: 2.10, p < .001), 30-day readmissions (OR: 1.14, CI95%: 1.014-1.289), and decreased discharge home (OR: 0.59, CI95%: 0.53-0.65, p < .001).

CONCLUSIONS

Given the association between behavioral symptoms and poor clinical outcomes, there is an urgent need to improve the provision of care for hospitalized PLWD.

Recent-Onset Altered Mental Status: Evaluation and Management

Potential precipitating factors for the recent onset of altered mental status (AMS) include primary central nervous system insults, systemic infections, metabolic disturbances, toxin exposure, medications, chronic systemic diseases, and psychiatric conditions. Delirium is also an important manifestation of AMS, especially in older people who are hospitalized. Clinicians should identify and treat reversible causes of the AMS, some of which require urgent intervention to minimize morbidity and mortality. A history and physical examination guide diagnostic testing. Laboratory testing, chest radiography, and electrocardiography help diagnose infections, metabolic disturbances, toxins, and systemic conditions. Neuroimaging with computed tomography or magnetic resonance imaging should be performed when the initial evaluation does not identify a cause or raises concern for intracranial pathology. Lumbar puncture and electroencephalography are also important diagnostic tests in the evaluation of AMS. Patients at increased risk of AMS benefit from preventive measures. The underlying etiology determines the definitive treatment. When intervention is needed to control patient behaviors that threaten themselves or others, nonpharmacologic interventions are preferred to medications. Physical restraints should rarely be used and only for the shortest time possible. Medications should be used only when nonpharmacologic treatments are ineffective.

Increased prevalence of impulse control disorder symptoms in endocrine diseases treated with dopamine agonists: a cross-sectional study

INTRODUCTION

Impulse control disorders (ICDs) have been described as a side effect of dopamine agonists (DAs) in neurological as well as endocrine conditions. Few studies have evaluated the neuropsychological effect of DAs in hyperprolactinemic patients, and these have reported a relationship between DAs and ICDs. Our objective was to screen for ICD symptoms in individuals with DA-treated endocrine conditions.

MATERIALS AND METHODS

A cross-sectional analysis was conducted on 132 patients with pituitary disorders treated with DAs (DA exposed), as well as 58 patients with pituitary disorders and no history of DA exposure (non-DA exposed). Participants responded to the full version of the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's disease (QUIP).

RESULTS

Compared with the non-DA-exposed group, a higher prevalence of DA-exposed patients tested positive for symptoms of any ICD or related behavior (52% vs. 31%, p < 0.01), any ICD (46% vs. 24%, p < 0.01), any related behavior (31% vs. 17%, p < 0.05), compulsive sexual behavior (27% vs. 14%, p < 0.04), and punding (20% vs. 7%, p < 0.02) by QUIP. On univariate analysis, DA treatment was associated with a two- to threefold increased risk of any ICD or related behavior [odds ratio (OR) 2.43] and any ICD (OR 2.70). In a multivariate analysis, independent risk factors for any ICD or related behavior were DA use (adjusted OR 2.22) and age (adjusted OR 6.76). Male gender was predictive of the risk of hypersexuality (adjusted OR 3.82).

DISCUSSION

Despite the QUIP limitations, a clear sign of increased risk of ICDs emerges in individuals with DA-treated pituitary disorders. Our data contribute to the growing evidence of DA-induced ICDs in endocrine conditions.

Assessment of children in the autistic spectrum disorder that carry the Thr92Ala-DIO2 polymorphism

INTRODUCTION

A polymorphism in the type 2 deiodinase (Thr92Ala-DIO2) gene has been associated with behavioral and cognitive dysfunction as well as neurodegeneration and oxidative stress in the central nervous system.

OBJECTIVE

To test whether the minor allele (Ala92) frequency (MAF) is increased in children in the autism spectrum disorder (ASD), and whether carriers of the minor allele exhibit more severe symptoms and/or worse adaptive behavior.

STUDY DESIGN

ASD children were evaluated at baseline and yearly throughout the study by psychologists using the following tools: autism behavior checklist, Vineland Adaptative Behaviour Scales II, non-verbal intelligence test SON-R 21/2-7, SON-R 6-40, Weschler scale for intelligence, and autism treatment evaluation checklist.

SETTINGS

Academic outpatient mental health facility in Sao Paulo, Brazil.

PARTICIPANTS

ASD boys and girls younger than 18 years of age. 132 consecutive ASD children, mostly boys (~ 80%); ~ 50% was classified as verbal. Exclusion criteria were coexistence of sensory and/or physical impairment, or any associated genetic syndromes.

RESULTS

Median follow-up was for an uninterrupted period of 937 days (139-1375 days), which did not vary significantly among the genotypes. The MAF was 47% in ASD patients vs. 51% in a local reference population with similar ethnic background; the clinical severity and progression were not affected by the minor allele. Carriers of the minor allele exhibited higher adaptive behavior in the domains "daily living skills" and "communication", which correlated positively with the dose of the minor allele.

CONCLUSION

The MAF is not different in ASD children, but carriers of the Thr92Ala-DIO2 polymorphism exhibited higher adaptive behavior.

Behavioural change in Prader-Willi syndrome during COVID-19 pandemic

BACKGROUND

Prader-Willi syndrome (PWS) is a rare genetic disorder that in many cases is associated with mental health disorders, in addition to characteristic symptoms such as hyperphagia. The current Sars-CoV-2 coronavirus pandemic has led to massive restrictions in health care and social life worldwide. People with PWS represent a particularly vulnerable population group to these restrictions, with unknown impact on their mental health.

METHODS

We conducted an online questionnaire to assess the impact of the restrictions associated with the COVID-19 pandemic on the mental health of people with PWS.

RESULTS

One hundred and eight caregivers completed the survey about individuals with PWS. Individuals with PWS > 6 years (n = 89) were included for evaluation with regard to psychopathological change. Respondents frequently reported an increase in psychopathological symptoms associated with PWS during the lockdown, with 51.7% reporting increased temper outbursts, 43.8% showing signs of sadness, 38.2% being anxious, 55.0% more irritable, and 39.3% showing more food seeking behaviour. Adjusted for the type of accommodation food seeking behaviour and irritability is increased to a significantly lesser extent in people with PWS accommodated in specialised care facilities compared with those living in their family home. No significant difference could be found between the sexes.

CONCLUSION

The COVID-19 pandemic has had a significant effect on the mental health of individuals with PWS, evidenced by an increase in behaviours associated with PWS, including temper outbursts, food-seeking, and irritability, which again underlines their need for specialised care. Individuals living with their families were particularly vulnerable, indicating that they and their families are in special need of support.

Brain mechanisms underlying neuropsychiatric symptoms in Alzheimer's disease: a systematic review of symptom-general and -specific lesion patterns

Neuropsychiatric symptoms (NPSs) are common in patients with Alzheimer's disease (AD) and are associated with accelerated cognitive impairment and earlier deaths. This review aims to explore the neural pathogenesis of NPSs in AD and its association with the progression of AD. We first provide a literature overview on the onset times of NPSs. Different NPSs occur in different disease stages of AD, but most symptoms appear in the preclinical AD or mild cognitive impairment stage and develop progressively. Next, we describe symptom-general and -specific patterns of brain lesions. Generally, the anterior cingulate cortex is a commonly damaged region across all symptoms, and the prefrontal cortex, especially the orbitofrontal cortex, is also a critical region associated with most NPSs. In contrast, the anterior cingulate-subcortical circuit is specifically related to apathy in AD, the frontal-limbic circuit is related to depression, and the amygdala circuit is related to anxiety. Finally, we elucidate the associations between the NPSs and AD by combining the onset time with the neural basis of NPSs.

Clinical Features and Outcomes of Anti-N-Methyl-d-Aspartate Receptor Encephalitis in Infants and Toddlers

OBJECTIVE

We describe the clinical features and outcomes of anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis in infants and toddlers.

METHODS

This was a single-center retrospective study. Infants and toddlers who met the diagnostic criteria for anti-NMDAR encephalitis were recruited for the study. Data on clinical features, treatment, and long-term outcomes were collected retrospectively.

RESULTS

A total of 41 patients (age range: six to 34 months; median age: 23 months; female: 19) were enrolled in this study. Nineteen (46%) patients exhibited classical anti-NMDAR encephalitis, whereas 22 (54%) patients exhibited anti-NMDAR encephalitis after viral encephalitis. There was a high presentation of movement disorders (100%), developmental regression (90%), abnormal behaviors (90%). All patients were administered first-line therapy, with only 17% of them being administered second-line immunotherapy. Two patients succumbed to the disease, whereas none of them relapsed. At the long-term follow-up (more than one year), 20 of 35 (57%) exhibited satisfactory outcomes (modified Rankin Scale ≤2). Compared with patients with classical anti-NMDAR encephalitis (n = 18), patients after viral encephalitis (n = 17) were more likely to have worse clinical outcomes. They exhibited a higher modified Rankin Scale/Pediatric Cerebral Performance Category score and more frequent seizures. A predictor of poor outcome was presentation after viral encephalitis (odds ratio 35.7, 95% confidence interval 4.64 to 275.03, P = 0.001).

CONCLUSION

Anti-NMDAR encephalitis in infants and toddlers clinically presents with movement disorders, developmental regression, and abnormal behaviors. Interestingly, this group had a higher proportion of patients after viral encephalitis, which is regarded as the only risk factor for poor outcomes.

Mental health and clinical psychological science in the time of COVID-19: Challenges, opportunities, and a call to action

COVID-19 presents significant social, economic, and medical challenges. Because COVID-19 has already begun to precipitate huge increases in mental health problems, clinical psychological science must assert a leadership role in guiding a national response to this secondary crisis. In this article, COVID-19 is conceptualized as a unique, compounding, multidimensional stressor that will create a vast need for intervention and necessitate new paradigms for mental health service delivery and training. Urgent challenge areas across developmental periods are discussed, followed by a review of psychological symptoms that likely will increase in prevalence and require innovative solutions in both science and practice. Implications for new research directions, clinical approaches, and policy issues are discussed to highlight the opportunities for clinical psychological science to emerge as an updated, contemporary field capable of addressing the burden of mental illness and distress in the wake of COVID-19 and beyond.

The impact of lockdown during SARS-CoV-2 outbreak on behavioral and psychological symptoms of dementia

Background

During Covid-19 pandemic, the Italian government adopted restrictive limitations and declared a national lockdown on March 9, which lasted until May 4 and produced dramatic consequences on people’s lives. The aim of our study was to assess the impact of prolonged lockdown on behavioral and psychological symptoms of dementia (BPSD).

Methods

Between April 30 and June 8, 2020, we interviewed with a telephone-based questionnaire the caregivers of the community-dwelling patients with dementia who had their follow-up visit scheduled from March 9 to May 15 and canceled due to lockdown. Among the information collected, patients’ BPSDs were assessed by the Neuropsychiatric Inventory (NPI). Non-parametric tests to compare differences between NPI scores over time and logistic regression models to explore the impact of different factors on BPSD worsening were performed.

Results

A total of 109 visits were canceled and 94/109 caregivers completed the interview. Apathy, irritability, agitation and aggression, and depression were the most common neuropsychiatric symptoms experienced by patients both at baseline and during Covid-19 pandemic. Changes in total NPI and caregiver distress scores between baseline and during lockdown, although statistically significant, were overall modest. The logistic regression model failed to determine predictors of BPSD worsening during lockdown.

Conclusion

This is one of the first studies to investigate the presence of BPSD during SARS-CoV-2 outbreak and related nationwide lockdown, showing only slight, likely not clinically relevant, differences in BPSD burden, concerning mostly agitation and aggression, anxiety, apathy and indifference, and irritability.

G-protein coupled receptor 88 knockdown in the associative striatum reduces psychiatric symptoms in a translational male rat model of Parkinson disease

BACKGROUND

In addition to motor disability, another characteristic feature of Parkinson disease is the early appearance of psychiatric symptoms, including apathy, depression, anxiety and cognitive deficits; treatments for these symptoms are limited by the development of adverse effects such as impulse-control disorders. In this context, we investigated the orphan G protein-coupled receptor 88 (GPR88) as a novel therapeutic target.

METHODS

We used lentiviral-mediated expression of specifically designed microRNA to knock down Gpr88 in a translational male rat model of early Parkinson disease obtained by dopamine loss in the dorsolateral striatum as a result of 6-hydroxydopamine lesions. We evaluated the impact of Gpr88 knockdown on the Parkinson disease model using behavioural, immunohistochemical and in situ hybridization studies.

RESULTS

Knockdown of Gpr88 in associative territories of the dorsal striatum efficiently reduced alterations in mood, motivation and cognition through modulation of the regulator of the G-protein signalling 4 and of the truncated splice variant of the FosB transcription factor. Knockdown of Gpr88 also reduced allostatic changes in striatal activity markers that may be related to patterns observed in patients and that provide support for an "overload" hypothesis for the etiology of the psychiatric symptoms of Parkinson disease.

LIMITATIONS

Behavioural tests assessing specific cognitive and motivational parameters are needed to further characterize the effects of the lesion and of Gpr88 knockdown in early-stage and advanced Parkinson disease models, presenting more extensive dopamine loss. Additional studies focusing on the direct and indirect striatal output pathways are also required, because little is known about the signalling pathways regulated by GPR88 in different striatal cell types.

CONCLUSION

GPR88 may constitute a highly relevant target for the treatment of the psychiatric symptoms of Parkinson disease.

Caffeine Consumption and Behavioral Symptoms in Nursing Home Residents: A Cross-Sectional Analysis

OBJECTIVE

Although behavioral changes are common in nursing home residents with dementia and caffeine is known to influence behavior in healthy adults, the effects of caffeine on the behavior of persons with dementia has received little attention. In this study we assessed the relationship of caffeine and behavioral symptoms in older persons with dementia.

DESIGN

A multicenter sub-cohort study embedded in the Elderly Care Physicians (ECP) training program.

SETTING

Dutch nursing homes associated with the ECP training program.

PARTICIPANTS

A total of 206 individuals with both diabetes and dementia resident in Dutch nursing homes.

MEASUREMENTS

Trainee ECPs collected data on caffeine consumption, cognition and behavioral symptoms using the NPI-NH, MDS-DRS and AES-C. Data on factors known to influence behavior in persons with dementia (e.g. marital status, kidney function, urinary tract infection and medication) were also collected.

RESULTS

Of the 206 participants, 70% showed behavioral symptoms. An increase in caffeine consumption was associated with a decrease in the presence of behavioral symptoms in the NPI-NH cluster affect and NPI-NH item agitation. Caffeine consumption groups also differed on the presence of disinhibition and depression. In addition, the severity of dementia influenced agitation, anxiety and the clusters affect and psychomotor.

CONCLUSION

In a large group of older persons with dementia resident in nursing homes, a low daily consumption of caffeine was associated with greater behavioral symptoms.

Parent-Reported Symptoms and Medications Used Among Children With Severe Neurological Impairment

IMPORTANCE

Children with severe neurological impairment (SNI) often take multiple medications to treat problematic symptoms. However, for children who cannot self-report symptoms, no system exists to assess multiple symptoms and their association with medication use.

OBJECTIVES

To assess the prevalence of 28 distinct symptoms, test whether higher global symptom scores (GSS) were associated with use of more medications, and assess the associations between specific symptoms and medications.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study was conducted between April 1, 2019, and December 31, 2019, using structured parent-reported symptom data paired with clinical and pharmacy data, at a single-center, large, hospital-based special health care needs clinic. Participants included children aged 1 to 18 years with SNI and 5 or more prescribed medications. Data analysis was performed from April to June 2020.

EXPOSURE

During routine clinical visits, parent-reported symptoms were collected using the validated 28-symptom Memorial Symptom Assessment Scale (MSAS) and merged with clinical and pharmacy data.

MAIN OUTCOMES AND MEASURES

Symptom prevalence, counts, and GSS (scored 0-100, with 100 being the worst) were calculated, and the association of GSS with medications was examined. To evaluate associations between symptom-medication pairs, the proportion of patients with a symptom who used a medication class or specific medication was calculated.

RESULTS

Of 100 patients, 55.0% were boys, the median (interquartile range [IQR]) age was 9 (5-12) years, 62.0% had 3 or more complex chronic conditions, 76.0% took 10 or more medications, and none were able to complete the MSAS themselves. Parents reported a median (IQR) of 7 (4-10) concurrent active symptoms. The median (IQR) GSS was 12.1 (5.4-20.8) (range, 0.0-41.2) and the GSS was 9.8 points (95% CI, 5.5-14.1 points) higher for those with worse recent health than usual. Irritability (65.0%), insomnia (55.0%), and pain (54.0%) were the most prevalent symptoms. Each 10-point GSS increase was associated with 12% (95% CI, 4%-19%) higher medication counts, adjusted for age and complex chronic condition count. Among the 54.0% of children with reported pain, 61.0% were prescribed an analgesic.

CONCLUSIONS AND RELEVANCE

These findings suggest that children with SNI reportedly experience substantial symptom burdens and that higher symptom scores are associated with increased medication use. Paired symptom-medication data may help clinicians identify targets for personalized symptom management, including underrecognized or undertreated symptoms.

Noradrenergic Signaling and Neuroinflammation Crosstalk Regulate Toxoplasma gondii-Induced Behavioral Changes

Infections of the nervous system elicit neuroimmune responses and alter neurotransmission, affecting host neurological functions. Chronic infection with the apicomplexan parasite Toxoplasma correlates with certain neurological disorders in humans and alters behavior in rodents. Here, we propose that the crosstalk between neurotransmission and neuroinflammation may underlie some of these cognitive changes. We discuss how T. gondii infection suppresses noradrenergic signaling and how the restoration of this pathway improves behavioral aberrations, suggesting that altered neurotransmission and neuroimmune responses may act in concert to perturb behavior. This interaction might apply to other infectious agents, such as viruses, that elicit cognitive changes. We hypothesize that neurotransmitter signaling in immune cells can contribute to behavioral changes associated with brain infection, offering opportunities for potential therapeutic targeting.

"Hey, we also have something to say": A qualitative study of Portuguese adolescents' and young people's experiences under COVID-19

OBJECTIVE

(1) To give adolescents and youth a voice and listen to the impact of coronavirus disease 2019 (COVID-19) in their lives; (2) to identify their coping strategies; (3) present lessons learned to be better prepared for future pandemics.

METHODS

Six hundred and seventeen participants from 16 to 24 years old (M = 19.2 years; F = 19.1 years) answered the online questionnaire during the pandemic lockdown. Sociodemographic data were analyzed with SPSS version 26 and qualitative data with MAXQDA 2020. Engel's Biopsychosocial model supported the analysis and data presentation.

RESULTS

in terms of impacts, stands out: biological-headaches and muscle pain; psychological-more time to perform pleasant and personal development activities, but more symptoms of depression, anxiety, and loneliness, longer screen time, and more substance use; social-increase of family conflicts and disagreements, loss of important life moments, contacts, and social skills, but it allows a greater selection of friendships. Regarding coping strategies, the importance of facing these times with a positive perspective, carrying out pleasurable activities, keeping in touch with family and friends, and establishing routines are emphasized. As lessons for future pandemics, the importance of respecting the norms of the Directorate-General for Health, the need for the National Health System to be prepared, as well as teachers and students for online learning, and studying the possibility of establishing routines with the support of television.

CONCLUSIONS

This study illustrates adolescents and young people's perception of the impacts of the pandemic upon them, as well as their competence to participate in the issues that directly affect them. Priorities to mitigate the impact of future pandemics are presented.

How specific are non-motor symptoms in the prodrome of Parkinson's disease compared to other movement disorders?

The clinical diagnosis of Parkinson's disease (PD) based on motor signs is often preceded by several non-motor symptoms that can indicate early prodromal neurodegenerative processes. Such prodromal symptoms can aid the early detection of PD, but their specificity for prodromal PD in comparison to prodromes of other movement disorders is still largely unclear. We here aim to give a first insight into the published evidence of prodromal non-motor symptoms in PD, dementia with Lewy bodies (DLB), multiple system atrophy (MSA), Huntington's disease (HD), progressive supranuclear palsy (PSP) and spinocerebellar ataxia (SCA). REM-sleep behavior disorder (RBD) and autonomic dysfunction have been observed in the prodromes of PD, MSA, DLB and SCA. Depression and cognitive decline have been reported for prodromal PD, DLB, HD, SCA, and PSP. Olfactory loss has only been described in prodromal PD/DLB. However, estimating the specificity of prodromal non-motor symptoms in PD is so far complicated by scarce prospective evidence and study limitations. Information on marker specificity is a prerequisite for an accurate early (differential) diagnosis of prodromal diseases, as well as specific recruitment for targeted neuroprotective interventions. We here would like to raise awareness of these issues and encourage further prospective research of prodromal non-motor symptoms in neurodegenerative movement disorders and other diseases.

Incarceration and pandemic-related restrictions during COVID-19: An empathic understanding of two worlds

This paper explores parallels between experiences of confinement due to pandemic-related restrictions and confinement as a result of legal incarceration. We compare experiences of social isolation, lack of choice, and reduced access to resources while also acknowledging the existence of significant differences between the two situations. We describe the ways in which experiences of confinement as part of COVID-19 regulations can provide the general public with insight into difficulties associated with incarceration and the negative effect it can have on psychological health.

Differences in Staff-Assessed Pain Behaviors among Newly Admitted Nursing Home Residents by Level of Cognitive Impairment

OBJECTIVE

Pain is common among nursing home residents with cognitive impairment and dementia. Pain is often underdiagnosed and undertreated, which may lead to adverse health outcomes. Nonverbal behaviors are valid indicators of pain, but the extent to which these behavioral expressions vary across levels of cognitive impairment is unknown. This study sought to examine differences in the prevalence of pain behaviors among nursing home residents with varying levels of cognitive impairment.

METHODS

The Minimum Data Set, version 3.0, was used to identify newly admitted nursing home residents with staff-assessed pain (2010-2016, n = 1,036,806). Staff-assessed pain behaviors included nonverbal sounds, vocal complaints, facial expressions, and protective body movements or postures over a 5-day look-back period for residents unable or unwilling to self-report pain. The Cognitive Function Scale was used to categorize residents as having no/mild, moderate, or severe cognitive impairment. Modified Poisson models provided adjusted prevalence ratios (aPR) and 95% CIs.

RESULTS

Compared to residents with no/mild cognitive impairments (any pain: 48.1%), residents with moderate cognitive impairment (any pain: 42.4%; aPR: 0.94 [95% CI 0.93-0.95]) and severe cognitive impairment (any pain: 38.4%; aPR: 0.86 [95% CI 0.85-0.88]) were less likely to have any pain behavior documented. Vocal pain behaviors were common (43.5% in residents with no/mild cognitive impairment), but less so in those with severe cognitive impairment (20.1%). Documentation of facial expressions and nonverbal pain behaviors was more frequent for residents with moderate and severe cognitive impairment than those with no/mild cognitive impairment.

CONCLUSIONS

The prevalence of behaviors indicative of pain differs by level of cognitive impairment. Pain evaluation and management plays an important role in treatment and care outcomes. Future work should examine how practitioners' perceptions of pain behaviors influence their ratings of pain intensity and treatment choices.

Impact of COVID-19 pandemic on mental health of young people and adults: a systematic review protocol of observational studies

INTRODUCTION

Since the WHO declared COVID-19 as a pandemic, the spread of the new coronavirus has been the focus of attention of scientists, governments and populations. One of the main concerns is the impact of this pandemic on health outcomes, mainly on mental health. Even though there are a few empirical studies on COVID-19 and mental health, so far, there is no systematic review about the impact of COVID-19 on mental health of young people and adults yet. We aim to critically synthesise the scientific evidence about the impact of the COVID-19 pandemic on the mental health of young people and adults.

METHODS AND ANALYSIS

A systematic review will be performed through eight databases: MEDLINE (Medical Literature Analysis and Retrieval System Online), ISI-of-Knowledge, CENTRAL (Cochrane Central Register of Controlled Trials), EMBASE (Excerpta Medica Database), SCOPUS, LILACS (Latin American and Caribbean Health Sciences Literature), PsycINFO (Psychology Information) and CNKI (Chinese National Knowledge Infrastructure), from inception until 30 June 2020. No restriction regarding the publication date, setting or languages will be considered. Preliminary search strategies were carried out on 29 March 2020 and will be updated in June 2020. The primary outcomes will be the prevalence and the severity of psychological symptoms in young people and adults (>18 years old) resulting from the impact of COVID-19 pandemic. Study selection will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Pooled standardised mean differences and 95% CIs will be calculated. The risk of bias of the observational studies will be assessed through the Methodological Index for Non-Randomised Studies (MINORS). Additionally, if sufficient data are available, a meta-analysis will be conducted. Heterogeneity between the studies will be determined by the I² statistics. Subgroup analyses will also be performed. Publication bias will be checked with funnel plots and Egger's test. Heterogeneity will be explored by random-effects analysis.

ETHICS AND DISSEMINATION

Ethical assessment was not required. Findings will be disseminated through peer-reviewed publication and will be presented at conferences related to this field.

Rasch analysis of the PANSS negative subscale and exploration of negative symptom trajectories in first-episode schizophrenia - data from the OPTiMiSE trial

The observed heterogeneity in negative symptom treatment response may be partly attributable to inadequate measurement tools or limitations in methods of analysis. Previous Item Response Theory models of the Positive and Negative Syndrome Scale (PANSS) have only examined samples of chronic patients and with mixed results. We examined the scalability of the negative subscale embedded in the PANSS and subsequently explored negative symptom trajectories across four weeks of amisulpride treatment. Data were derived from the OPTiMiSE trial comprising 446 patients with first-episode schizophrenia or schizophreniform disorder. Using the Rasch Model to examine psychometric properties of the PANSS negative subscale, we found that the composite score across items was not an adequate measure of negative symptom severity. Consequently, we chose an exploratory statistical approach involving Principal Component Analysis which yielded one significant component clustering into two significant symptom trajectories: 1) Subtle but constant decrease in negative symptom severity (N = 323; 72%), and 2) symptom instability across visits (N = 19; 4%). Explorative analytic methods as presented here may pave the way for more efficient and sensitive methods of analyzing negative symptom response in research and in clinical practice.

Effects of Overweight and Obesity in Pregnancy on Health of the Offspring

Overweight and obesity in pregnancy confer a wide range of risks on mother, fetus, and offspring throughout their lives. In addition to compounding many common pregnancy complications, including both iatrogenic preterm delivery and cesarean delivery, obesity is associated with multiple fetal anomalies, metabolic sequelae including diabetes and obesity, allergy and asthma, attention-deficit disorder, and likely many other challenges for the offspring. As targeted interventions are being developed, encouraging solid nutrition and exercise in women of childbearing age may stave off risks and mitigate obesity in the next generation.

Bilateral basal ganglia infarcts presenting as rapid onset cognitive and behavioral disturbance

We describe a rare case of a patient with rapid onset, prominent cognitive and behavioral changes who presented to our rapidly progressive dementia program with symptoms ultimately attributed to bilateral basal ganglia infarcts involving the caudate heads. We review the longitudinal clinical presentation and neuropsychological testing for this patient, and discuss the implicated basal ganglia and frontal lobe neuroanatomy.

Neuropsychiatric symptoms and cognitive abilities over the initial quinquennium of Parkinson disease

OBJECTIVE

To determine the evolution of numerous neuropsychiatric symptoms and cognitive abilities in Parkinson disease from disease onset.

METHODS

Prospectively collected, longitudinal (untreated, disease onset to year 5), observational data from Parkinson's Progression Markers Initiative annual visits was used to evaluate prevalence, correlates, and treatment of 10 neuropsychiatric symptoms and cognitive impairment in Parkinson disease participants and matched healthy controls.

RESULTS

Of 423 Parkinson disease participants evaluated at baseline, 315 (74.5%) were assessed at year 5. Eight neuropsychiatric symptoms studied increased in absolute prevalence by 6.2-20.9% at year 5 relative to baseline, and cognitive impairment increased by 2.7-6.2%. In comparison, the frequency of neuropsychiatric symptoms in healthy controls remained stable or declined over time. Antidepressant and anxiolytic/hypnotic use in Parkinson disease were common at baseline and increased over time (18% to 27% for the former; 13% to 24% for the latter); antipsychotic and cognitive-enhancing medication use was uncommon throughout (2% and 5% of patients at year 5); and potentially harmful anticholinergic medication use was common and increased over time. At year 5 the cross-sectional prevalence for having three or more neuropsychiatric disorders/cognitive impairment was 56% for Parkinson disease participants versus 13% for healthy controls, and by then seven of the examined disorders had either occurred or been treated at some time point in the majority of Parkinson disease patients. Principal component analysis suggested an affective disorder subtype only.

INTERPRETATION

Neuropsychiatric features in Parkinson disease are common from the onset, increase over time, are frequently comorbid, and fluctuate in severity.

Development of externalizing symptoms across the toddler period: The critical role of older siblings

We examined child and family risk factors that were associated with the development of individual differences in externalizing problems across the toddler years. Our central hypothesis was that toddlers with more aggressive and disruptive older siblings would be at elevated risk for heightened levels of externalizing behavior. We tested this hypothesis in the context of other theoretically relevant risk factors: toddlers' inhibitory and internalized control, experiences of coercive parental discipline, and gender. Participants were 167 toddlers, their older siblings, and parents in a longitudinal study following younger siblings across the first 3 years of life. Mothers and fathers contributed ratings of externalizing symptoms between 1 and 18 months across the transition to siblinghood for older siblings and 18 to 36 months for younger siblings. Toddlers' inhibitory and internalized control were assessed using behavioral and parent report measures, and parents completed questionnaires concerning their use of coercive discipline. Individual differences in toddler externalizing symptoms were highly stable between 18 and 36 months of age for a sample of second-born children with older siblings, even though there was evidence of significant decline in externalizing symptoms from 18 to 36 months. As predicted, toddlers with elevated levels of externalizing symptoms tended to have older siblings with higher externalizing difficulties across the first 18 months of the younger sibling's life. Thus, these findings highlighted the need for further research on older siblings' contributions to the behavioral development of their toddler-age younger siblings.

A profile of mental health and behaviour in Prader-Willi syndrome

BACKGROUND

Prader-Willi syndrome (PWS) is a neurogenetic syndrome with an associated behavioural phenotype and a high incidence of behaviours of concern and psychiatric co-morbidity. These associated behaviours and co-morbidities are not well addressed by existing interventions, and they impact significantly on affected individuals and their caregivers.

METHODS

We undertook a national survey of the needs of individuals with PWS and their families in Ireland. In this paper, we report on the parent/caregiver-reported mental health, behavioural and access to services.

RESULTS

Over 50% of individuals with PWS in this survey had at least one reported psychiatric diagnosis, the most common diagnosis was anxiety. The most commonly reported behaviours in children were skin picking, repetitive questioning, difficulty transitioning and non-compliance. The same four behaviours were reported by caregivers as being the most commonly occurring in adolescents and adults in addition to food-seeking behaviours. Increased needs for mental health services were also reported by caregivers. Individuals with PWS had an average wait of 22 months for an appointment with a psychologist and 4 months for an appointment with a psychiatrist.

CONCLUSION

This study highlighted high levels of psychiatric co-morbidities and behavioural concerns in individuals with PWS in Ireland. The findings of this study suggest that there is an urgent need to provide specialist psychiatric and behavioural interventions to manage complex mental health and behavioural needs to better support individuals with PWS and reduce caregiver burden.

Health-related quality of life amongst primary caregivers of children with intellectual disability

BACKGROUND

Children with intellectual disability (ID) frequently have significant educational, social and health care needs, resulting in caregivers often experiencing a wide range of negative effects. This paper aims to determine the impact of childhood ID on caregivers' health-related quality of life (HRQoL) across co-morbid diagnostic groups. The second aim of this study is to determine the risk factors associated with lower HRQoL in this population.

METHODS

Caregivers of a child with ID aged between 2 and 12 years old completed an online survey to determine their HRQoL using the EQ-5D-5L measure. They were also asked demographic questions and about their dependent child's level of behavioural and emotional difficulties.

RESULTS

Of the total sample of 634 caregivers, 604 caregivers completed all five questions of the EQ-5D-5L. The mean age of caregivers was 39.1 years and 91% were women. Caregivers spent on average 66.6 h per week caring for their child related to their child's disability. The mean EQ-5D-5L score of caregivers was 0.80 (95% confidence interval: 0.79, 0.82), which is below the estimated Australian population norms (mean utility score of 0.92) for the age-equivalent population. Caregivers of children with autism spectrum disorders reported the lowest HRQoL (0.77, 95% confidence interval: 0.74, 0.79) of the five included co-morbid diagnostic groups. Caregivers with a lower income, a perceived low level of social support and children with higher degree of behavioural and emotional problems were likely to have a statistically lower HRQoL.

CONCLUSIONS

This is the first study to produce utility values for caregivers of children with ID. The utility values can be used to compare health states and can be used to inform comparative cost-effectiveness analyses. Demonstrating that caregivers of children with ID have reduced HRQoL and that this is associated with the degree of behavioural and emotional problems has important policy implications, highlighting the potential for policy interventions that target behavioural and emotional problems to improve outcomes for caregivers.

Associations Between Sexual Function and Disordered Eating Among Undergraduate Women: An Emphasis on Sexual Pain and Distress

The limited body of research on sexuality in eating disorders supports the occurrence of considerable sexual concerns. The aim of the present study was to examine eating disorder symptoms in relation to sexual function, and sexual pain in particular. Female undergraduate students completed a series of online questionnaires. All domains of sexual function were predicted by aspects of disordered eating, with disordered eating generally being associated with more sexual difficulties. Psychological characteristics common to those with eating pathology were also associated with sexuality variables, such that psychological maladjustment was associated with poorer sexual function. Psychological maladjustment was found to mediate the association between eating disorder risk and sexual function. The results of this study suggest that sexual function should be addressed during eating disorder care.

Association of brain amyloidosis with the incidence and frequency of neuropsychiatric symptoms in ADNI: a multisite observational cohort study

OBJECTIVE

To investigate the relationship between amyloid burden and frequency of existing and incidence of new neuropsychiatric symptoms (NPS) in elderly with and without cognitive decline.

METHODS

275 cognitively normal controls (NC), 100 subjective memory complaint (SMC), 559 mild cognitive impairment (MCI) and 143 Alzheimer's disease dementia subjects from the Alzheimer's Disease Neuroimaging Initiative received (¹⁸F)-florbetapir positron emission tomography (PET) scans. Yearly neuropsychiatric inventory (Neuropsychiatric Inventory (NPI)/NPI-Questionnaire) data were collected from the study partners at each visit. Mean standard uptake volume ratios (SUVR) normalised to whole cerebellum were obtained. Positive amyloid PET scan was defined as mean SUVR ≥1.17. Fisher's exact test was used to compare frequency and incidence between amyloid positive and amyloid negative subjects. Survival analyses were used to estimate of neuropsychiatric symptoms (NPS) between amyloid positive and amyloid negative subjects. Survival analyses were used to estimate hazard ratios for developing the most common NPS by amyloid status.

RESULTS

No differences in NPS frequency were seen between amyloid positive and amyloid negative NC, SMC, MCI or dementia groups. MCI subjects with amyloid pathology however tended to have greater frequency x severity (FxS) of anxiety, hallucinations, delusions, apathy, disinhibition, irritability, aberrant motor behavior, and appetite, but not agitation, depression, night-time disturbances, or elation. MCI subjects with amyloid pathology were at greater risk for developing apathy, anxiety and agitation over time. Baseline presence of agitation and apathy and new onset agitation, irritability and apathy predicted faster conversion to dementia among MCI subjects.

CONCLUSIONS

Amyloid pathology is associated with greater rate of development of new NPS in MCI. Anxiety and delusions are significant predictors of amyloid pathology. Agitation, irritability and apathy are significant predictors for conversion from MCI to dementia.

ALS Cognitive Behavioral Screen (ALS-CBS): normative values for the Italian population and clinical usability

Amyotrophic lateral sclerosis (ALS) patients often express cognitive and behavioral dysfunctions within the so-called "frontotemporal spectrum disorders." Guidelines recommend screening of such dysfunctions, albeit only ALS dedicated tools are eventually suitable, due to the profound motor limitations induced by the disease. ALS Cognitive Behavioral Screen (ALS-CBS) is such a screening tool but normative data are not available, limiting its widespread implementation. Our aim consisted in producing normative data for the Italian version of the ALS-CBS. The scale was administered to n = 458 healthy controls with different age and education. Following translation and back translation of the original version of the test, normative data and correction scores for the ALS-CBS cognitive subtest (ALS-CBSci) were generated. Furthermore, n = 100 ALS consecutive outpatients with a wide range of cognitive and motor severity underwent to the ALS-CBS, besides FAB and Weigl sorting test (WST), in order to check its usability. Completion rate was 100% for ALS-CBS and WST, and 68% for the FAB. Corrected ALS-CBS scores showed 12% detection rate of significant cognitive dysfunction with a moderate kappa with FAB and WST. For the ALS-CBS behavioral subtest (ALS-CBSbi), a caregiver was available for n = 81 ALS patients and asked to complete the subset. The detection rate for behavioral dysfunction was 55.5%, and a mild correlation between with the Caregiver Burden Inventory was present (r = - 0.26, p = 0.04). In conclusion, we offer here normative data for the ALS-CBS, a handy tool for screening frontotemporal spectrum dysfunctions in ALS patients, and confirm its usability and validity in an outpatient setting.

Reduced Amygdala-Prefrontal Functional Connectivity in Children With Autism Spectrum Disorder and Co-occurring Disruptive Behavior

BACKGROUND

Disruptive behaviors are prevalent in children with autism spectrum disorder (ASD) and often cause substantial impairments. However, the underlying neural mechanisms of disruptive behaviors remain poorly understood in ASD. In children without ASD, disruptive behavior is associated with amygdala hyperactivity and reduced connectivity with the ventrolateral prefrontal cortex (vlPFC). This study examined amygdala reactivity and connectivity in children with ASD with and without co-occurring disruptive behavior disorders. We also investigated differential contributions of externalizing behaviors and callous-unemotional traits to variance in amygdala connectivity and reactivity.

METHODS

This cross-sectional study involved behavioral assessments and neuroimaging in three groups of children 8 to 16 years of age: 18 children had ASD and disruptive behavior, 20 children had ASD without disruptive behavior, and 19 children were typically developing control participants matched for age, gender, and IQ. During functional magnetic resonance imaging, participants completed an emotion perception task of fearful versus calm faces. Task-specific changes in amygdala reactivity and connectivity were examined using whole-brain, psychophysiological interaction, and multiple regression analyses.

RESULTS

Children with ASD and disruptive behavior showed reduced amygdala-vlPFC connectivity compared with children with ASD without disruptive behavior. Externalizing behaviors and callous-unemotional traits were associated with amygdala reactivity to fearful faces in children with ASD after controlling for suppressor effects.

CONCLUSIONS

Reduced amygdala-vlPFC connectivity during fear processing may differentiate children with ASD and disruptive behavior from children with ASD without disruptive behavior. The presence of callous-unemotional traits may have implications for identifying differential patterns of amygdala activity associated with increased risk of aggression in ASD. These findings suggest a neural mechanism of emotion dysregulation associated with disruptive behavior in children with ASD.

Assessing apathy in multiple sclerosis: Validation of the dimensional apathy scale and comparison with apathy evaluation scale

BACKGROUND

Apathy is a predictor of cognitive decline in the course of multiple sclerosis (MS). Early identification of apathetic patients is relevant in clinical settings.

OBJECTIVE

To assess applicability and psychometric properties of the self-rated version of the Dimensional Apathy Scale (DAS) in a large cohort of patients with MS and to compare its diagnosing accuracy with that of the Apathy Evaluation Scale (AES).

METHODS

One hundred and twenty-four patients underwent clinical interview based on diagnostic criteria for apathy, DAS, AES, and assessment of depression, global cognitive functioning, and non-verbal intelligence.

RESULTS

According to diagnostic criteria, apathy occurred in 33.4% of the patients. The DAS showed high consistency, and good convergent, discriminant and criterion validity. Factor analysis indicated a three-factor structure: executive, behavioural and emotional apathy. Unlike AES, no significant association between DAS score and severity of neurological disability (expressed by EDSS total score) was found, suggesting that the DAS might be less related to levels of disability. Receiver operating characteristics analyses, with clinical diagnostic criteria for apathy as the gold standard, revealed that a DAS score of 28/29 and an AES score of 35/36 were optimal cut-off values for identifying clinically relevant apathy. The two scales had similar diagnostic accuracy in the present sample.

CONCLUSIONS

The DAS is a valid and reliable multidimensional tool to assess apathy in MS, with diagnostic accuracy similar to that of the AES. However, the DAS score appears to be less strongly related to neurological disability.

Can Anything Good Ever Come From Bearing Migraine Attacks? Suggestions for a Comprehensive Concept of Gain in Migraine

PURPOSE OF REVIEW

The purpose of this review is to summarise the current state of knowledge concerning known types of gain, the reasons why patients might seek it, as well as implications for headache disorders.

RECENT FINDINGS

Even though the subject has been studied in the past, it received less attention in recent years. There is no doubt that migraine is a highly disabling disorder. However, attacks sometimes may be beneficial for the migraine brain as a time-out from the daily routine. On the other hand, patients are often stigmatised as trying to satisfy other needs through their disease. These "other needs" may be the exaggerated seeking for attention and affection or an undue official sickness certificate and were named secondary gain. Striving for secondary gain denotes a behaviour that aims at benefiting from a disease in a way that is seen as inappropriate by others. The fact that the term has persisted in doctors' vocabulary for decades probably indicates that it designates a concept considered relevant by many. However, its usage is complicated by its usually imprecise definition. We found in a literature search that the strive for secondary gain is not limited to neurosis, might both occur consciously and unconsciously, sometimes may aim at financial gain and sometimes at social gain, and can either be potentially expected or readily obtained. This behaviour mainly seems to aim at shaping one's interactions with the environment. Its causes have not been elucidated completely, though, but "unrequited demands for love, attention and affection" have been postulated. The desire for social gain can be influenced by approaches based upon behavioural psychology. Broaching the issue of secondary gain may be beneficial in the daily clinical routine.

Prevalence and Severity of Neuropsychiatric Symptoms in Early- Versus Late-Onset Alzheimer's Disease

BACKGROUND

The study aimed to compare neuropsychiatric symptoms (NPS) in people with early-onset Alzheimer's disease (EOAD) and late-onset AD (LOAD).

METHODS

Fifty-six participants with LOAD and 24 participants with EOAD having mild dementia were assessed for NPS for their frequency, severity, and caregiver distress as measured by Neuropsychiatry Inventory (NPI) along with assessments of cognition and functional dependence.

RESULTS

Participants with EOAD and LOAD were not significantly different for total NPI score (P = .057). Early-onset Alzheimer disease had greater prevalence of all the NPS except apathy. Participants with EOAD were significantly worse on anxiety (P = .03), irritability (P = .01), and sleep (P < .01) subscales and their carers significantly more distressed by their irritability (P = .002) and sleeping patterns (P = .005). Regression analysis showed that higher NPI score was associated with longer duration of illness in EOAD and higher functional dependence in LOAD.

CONCLUSIONS

The NPS severity was similar between EOAD and LOAD although EOAD had higher symptom prevalence and carer distress.

Quasi-experimental evidence on short- and long-term consequences of bullying victimization: A meta-analysis

Exposure to bullying victimization is associated with a wide-range of short and long-term adverse outcomes. However, the extent to which these associations reflect a causal influence of bullying victimization remains disputed. Here, we aimed to provide the most stringent evidence regarding the consequences of bullying victimization by meta-analyzing all relevant quasi-experimental (QE) studies. Multilevel random effects models and metaregression were employed to (a) estimate the pooled QE-adjusted effect size (Cohen d) for bullying victimization on outcomes and to (b) evaluate potential sources of heterogeneity. A total of 16 studies were included. We derived 101 QE-estimates from three different methods (twin design, fixed effects analysis, and propensity score matching) for three pools of outcomes (internalizing symptoms, externalizing symptoms, academic difficulties). QE-adjusted effects were small for internalizing symptoms (dadjusted = 0.27, 95% CI [0.05, 0.49]), and smaller for externalizing symptoms (dadjusted = 0.15, 95% CI [0.10, 0.21]) and academic difficulties (dadjusted = 0.10, 95% CI [0.06, 0.13]). Accounting for a shared rater effect between the exposure and the outcome further reduced the effect for internalizing (dnonshared rater = 0.14, 95% CI [0.05, 0.23]) and externalizing symptoms (dnonshared rater = 0.06, 95% CI [0.01, 0.11]). Finally, the adverse effects declined in the long-term, most markedly for internalizing symptoms (dlong-term = 0.06, 95% CI [-0.01, 0.13]). Based on the most stringent evidence available to date, findings indicate that bullying victimization may causally impact children's wellbeing in the short-term, especially anxiety and depression levels. The reduction of adverse effects over time highlights the potential for resilience in individuals who have experienced bullying. Secondary preventive interventions in bullied children should therefore focus on resilience and address children's preexisting vulnerabilities.

Lifelong consequences of brain injuries during development: From risk to resilience

Traumatic brain injuries in children represent a major public health issue and even relatively mild injuries can have lifelong consequences. However, the outcomes from these injuries are highly heterogeneous, with most individuals recovering fully, but a substantial subset experiencing prolonged or permanent disabilities across a number of domains. Moreover, brain injuries predispose individuals to other kinds of neuropsychiatric and somatic illnesses. Critically, the severity of the injury only partially predicts subsequent outcomes, thus other factors must be involved. In this review, we discuss the psychological, social, neuroendocrine, and autonomic processes that are disrupted following traumatic brain injury during development, and consider the mechanisms the mediate risk or resilience after traumatic brain injury in this vulnerable population.

[Social Behavioral Problems after Brain Injury]

Various types of aberrant social behaviors may occur after brain injury. Some of these behaviors might be understood as direct consequences of brain injury; apathy, disinhibition, and executive dysfunction are the three major domains of aberrant social behaviors after injury of the prefrontal cortex. In addition, psychosis, pseudobulbar affect, depression, and fatigue are common symptoms that affect social behavior after brain injury. To evaluate behavioral symptoms, it is important to obtain information based on the context of patient's daily life. Individualized interventions such as pharmacotherapy, disease education and environmental control would improve the patient's social function.

Participatory Peer Research in the Treatment of Young Adults With Mild Intellectual Disabilities and Severe Behavioral Problems

This study provides an illustration of a research design complementary to randomized controlled trial to evaluate program effects, namely, participatory peer research (PPR). The PPR described in current study was carried out in a small sample (N = 10) of young adults with mild intellectual disabilities (MID) and severe behavioral problems. During the PPR intervention, control and feedback to individuals is restored by training them to become participant-researchers, who collaborate in a small group of people with MID. Their research is aimed at the problems the young adults perceive and/or specific subjects of their interest. The study was designed as a multiple case study with an experimental and comparison group. Questionnaires and a semistructured interview were administered before and after the PPR project. Results of Reliable Change Index (RCI) analyses showed a decrease in self-serving cognitive distortions in the PPR group, but not in the comparison group. These results indicate that PPR helps to compensate for a lack of adequate feedback and control, and in turn may decrease distorted thinking and thereby possibly later challenging behavior.

The Neuropsychiatry of Parkinson Disease: A Perfect Storm

Affective disorders, cognitive decline, and psychosis have long been recognized as common in Parkinson disease (PD), and other psychiatric disorders include impulse control disorders, anxiety symptoms, disorders of sleep and wakefulness, and apathy. Psychiatric aspects of PD are associated with numerous adverse outcomes, yet in spite of this and their frequent occurrence, there is incomplete understanding of epidemiology, presentation, risk factors, neural substrate, and management strategies. Psychiatric features are typically multimorbid, and there is great intra- and interindividual variability in presentation. The hallmark neuropathophysiological changes that occur in PD, plus the association between exposure to dopaminergic medications and certain psychiatric disorders, suggest a neurobiological basis for many psychiatric symptoms, although psychological factors are involved as well. There is evidence that psychiatric disorders in PD are still under-recognized and undertreated and although psychotropic medication use is common, controlled studies demonstrating efficacy and tolerability are largely lacking. Future research on neuropsychiatric complications in PD should be oriented toward determining modifiable correlates or risk factors and establishing efficacious and well-tolerated treatment strategies.

Adults with Down syndrome: a comprehensive approach to manage complexity

BACKGROUND

Down syndrome (DS) is characterised by premature ageing that affects selected organ systems, and persons with this condition can present patterns of co-morbidities and deficits often observed in the older population without DS. However, information on the characteristics of adult persons with DS is limited. The objective of the study is to describe characteristics of adults with DS collected with a standardised, comprehensive assessment instrument.

METHODS

Cross-sectional study. Four hundred thirty adults with DS (age range 18/75 years) from three countries (Italy, n = 95; USA, n = 175; and Canada, n = 160). A standardised assessment instrument (interRAI intellectual disability) was used to assess sample characteristics.

RESULTS

Mean age ranged from 35.2 (standard deviation 12.0) years in the US sample to 48.8 (standard deviation 9.0) years in the Canadian sample. Most participants in the Italian and US sample were living in private homes, while more than half of those in the Canadian sample were institutionalised. Prevalences of geriatric conditions, including cognitive deficits, disability in the common activities of daily living, symptoms of withdrawal or anhedonia, aggressive behaviour, communication problems, falls and hearing problems were high in the study sample. Gastrointestinal symptoms, skin and dental problems and obesity were also frequently observed.

CONCLUSIONS

Adults with DS present with a high level of complexity, which may suggest the need for an approach based on a comprehensive assessment and management that can provide adequate care. Further research is needed to understand better the effectiveness of such an approach in the DS population.

Early recognition and treatment of neuropsychiatric symptoms to improve quality of life in early Alzheimer's disease: protocol of the BEAT-IT study

BACKGROUND

Neuropsychiatric symptoms (NPS) are very common in patients with mild cognitive impairment (MCI) and Alzheimer's disease (AD) dementia and are associated with various disadvantageous clinical outcomes including a negative impact on quality of life, caregiver burden, and accelerated disease progression. Despite growing evidence of the efficacy of (non)pharmacological interventions to reduce these symptoms, NPS remain underrecognized and undertreated in memory clinics. The BEhavioural symptoms in Alzheimer's disease Towards early Identification and Treatment (BEAT-IT) study is developed to (1) investigate the neurobiological etiology of NPS in AD and (2) study the effectiveness of the Describe, Investigate, Create, Evaluate (DICE) approach to structure and standardize the current care of NPS in AD. By means of the DICE method, we aim to improve the quality of life of AD patients with NPS and their caregivers who visit the memory clinic. This paper describes the protocol for the intervention study that incorporates the latter aim.

METHODS

We aim to enroll a total of 150 community-dwelling patients with MCI or AD and their caregivers in two waves. First, we will recruit a control group who will receive care as usual. Next, the second wave of participants will undergo the DICE method. This approach consists of the following steps: (1) describe the context in which NPS occur, (2) investigate the possible causes, (3) create and implement a treatment plan, and (4) evaluate whether these interventions are effective. Primary outcomes are the quality of life of patients and their caregivers. Secondary outcomes include NPS change, caregiver burden, caregivers' confidence managing NPS, psychotropic medication use, the experiences of patients and caregivers who underwent the DICE method, and the cost-effectiveness of the intervention.

CONCLUSIONS

This paper describes the protocol of an intervention study that is part of the BEAT-IT study and aims to improve current recognition and treatment of NPS in AD by structuring and standardizing the detection and treatment of NPS in AD using the DICE approach.

TRIAL REGISTRATION

The trial was registered on the Netherlands Trial Registry ( NTR7459 ); registered 6 September 2018.

Movement disorders and nonmotor neuropsychological symptoms in children and adults with classical galactosemia

Although movement disorders (MDs) are known complications, the exact frequency and severity remains uncertain in patients with classical galactosemia, especially in children. We determined the frequency, classification and severity of MDs in a cohort of pediatric and adult galactosemia patients, and assessed the association with nonmotor neuropsychological symptoms and daily functioning. Patients from seven centers in the United Kingdom and the Netherlands with a confirmed galactosemia diagnosis were invited to participate. A videotaped neurological examination was performed and an expert panel scored the presence, classification and severity of MDs. Disease characteristics, nonmotor neuropsychological symptoms, and daily functioning were evaluated with structured interviews and validated questionnaires (Achenbach, Vineland, Health Assessment Questionnaire, SIP68). We recruited 37 patients; 19 adults (mean age 32.6 years) and 18 children (mean age 10.7 years). Subjective self-reports revealed motor symptoms in 19/37 (51.4%), similar to the objective (video) assessment, with MDs in 18/37 patients (48.6%). The objective severity scores were moderate to severe in one third (6/37). Dystonia was the overall major feature, with additional tremor in adults, and myoclonus in children. Behavioral or psychiatric problems were present in 47.2%, mostly internalizing problems, and associated with MDs. Daily functioning was significantly impaired in the majority of patients. Only one patient received symptomatic treatment for MDs. We show that MDs and nonmotor neuropsychological symptoms are frequent in both children and adults with classical galactosemia.
