Frequency of anxiety after stroke: An updated systematic review and meta-analysis of observational studies

Dorsal dentate gyrus mediated enriched environment-induced anxiolytic and antidepressant effects in cortical infarcted mice

Anxiety and depression are the most common mental health disorders worldwide, each affecting around 30% stroke survivors. These complications not only affect the functional recovery and quality of life in stroke patients, but also are distressing for caregivers. However, effective treatments are still lacking. Enriched environment (EE), characterized with novel and multi-dimensional stimulation, has been reported to exert therapeutic effects on physical and cognitive function. In addition, EE also had potential positive effects on emotional disorders after ischemic stroke; however, the underling mechanisms have not been well elucidated. This study aimed to explore the effectiveness of EE on emotional disorders after cerebral ischemia and its underling mechanism. Sensorimotor cortical infarction was induced by photothrombosis with stable infarct location and volume, resulting in motor dysfunction, anxiety and depression-like behaviors in mice, with decreased ALFF and ReHo values and decreased c-fos expression in the infarction area and adjacent regions. Seven days' EE treatment significantly improved motor function of contralateral forelimb and exhibited anxiolytic and antidepressant effects in infarcted mice. Compared to the mice housing in a standard environment, those subjected to acute EE stimulation had significantly increased ALFF and ReHo values in the bilateral somatosensory cortex (S1, S2), dorsal dentate gyrus (dDG), dorsal CA1 of hippocampus (dCA1), lateral habenular nucleus (LHb), periaqueductal gray (PAG), ipsilateral primary motor cortex (M1), retrosplenial cortex (RSC), parietal association cortex (PtA), dorsal CA3 of hippocampus (dCA3), claustrum (Cl), ventral pallidum (VP), amygdala (Amy), and contralateral auditory cortex (Au). Some of, but not all, the ipsilateral brain regions mentioned above showed accompanying increases in c-fos expression with the most significant changes in the dDG. The number of FosB positive cells in the dDG, decreased in infarcted mice, was significantly increased after chronic EE treatment. Chemogenetic activation of dDG neurons reduced anxiety and depressive-like behaviors in infarcted mice, while neuronal inhibition resulted in void of the anxiolytic and antidepressant effects of EE. Altogether, these findings indicated that dDG neurons may mediate EE-triggered anxiolytic and antidepressant effects in cortical infarcted mice.

Psychological interventions for mood and cognition after stroke and transient ischaemic attack: A protocol for an umbrella review

Background

People who have had a stroke or a Transient Ischaemic Attack (TIA) can experience psychological and/or cognitive difficulties. The body of research for psychological and neuropsychological interventions after stroke is growing, however, published systematic reviews vary in scope and methodology, with different types and severity of strokes included, and at times, diverse conclusions drawn about the effectiveness of the interventions evaluated. In this umbrella review, we aim to systematically summarise the existing systematic reviews evaluating psychological interventions for mood and cognition post-stroke/TIA.

Methods

We will conduct this umbrella review according to the JBI Manual for Evidence Synthesis. The following databases will be searched from inception: Cochrane Database of Systematic Reviews, Database of Reviews of Effects (DARE), MEDLINE, Embase, CINAHL, PsycINFO, and Epistemonikos. Systematic reviews with or without meta-analysis published until the search date will be included. Reviews including psychological interventions addressing mood and/or cognition outcomes for any stroke type or severity will be screened for eligibility. A narrative synthesis, including content analysis, will be used. Each stage of the review will be processed by two independent reviewers and a third reviewer will be considered to resolve disagreements. The methodological quality of the included reviews will be assessed using AMSTAR 2.

Discussion

Existing systematic reviews provide varied evidence on the effectiveness of psychological interventions post-stroke/TIA. This umbrella review aims to summarise knowledge and evidence on different types of psychological and neuropsychological interventions targeting mood and cognition. Findings will highlight important knowledge gaps and help prioritise future research questions.

Systematic Review Registration

This protocol was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO) on November 15, 2022; PROSPERO CRD42022375947.

Psychosocial well-being after stroke in Aotearoa New Zealand: a qualitative metasynthesis

PURPOSE

Psychosocial well-being is key to living well after stroke, but often significantly affected by stroke. Existing understandings consider well-being comes from positive mood, social relationships, self-identity and engagement in meaningful activities. However, these understandings are socioculturally located and not necessarily universally applicable. This qualitative metasynthesis examined how people experience well-being after a stroke in Aotearoa New Zealand.

MATERIAL AND METHODS

This metasynthesis was underpinned by He Awa Whiria (Braided Rivers), a model which prompts researchers to uniquely engage with Māori and non-Māori knowledges. A systematic search identified 18 articles exploring experiences of people with stroke in Aotearoa. Articles were analysed using reflexive thematic analysis.

RESULTS

We constructed three themes which reflect experiences of well-being: connection within a constellation of relationships, being grounded in one's enduring and evolving identities, and being at-home in the present whilst (re)visioning the future.

CONCLUSION

Well-being is multi-faceted. In Aotearoa, it is inherently collective while also deeply personal. Well-being is collectively achieved through connections with self, others, community and culture, and embedded within personal and collective temporal worlds. These rich understandings of well-being can open up different considerations of how well-being is supported by and within stroke services.

Prevalence of depression and anxiety symptoms after stroke in young adults: A systematic review and meta-analysis

BACKGROUND

Young adults with stroke have distinct professional and social roles making them vulnerable to symptoms of post-stroke depression (PSD) and post-stroke anxiety (PSA). Prior reviews have examined the prevalence of anxiety and depression in stroke populations. However, there are a lack of studies that have focused on these conditions in young adults.

OBJECTIVE

We performed a systematic review and meta-analysis of observational studies that reported on symptoms of PSD, PSA and comorbid PSD/PSA in young adults aged 18 to 55 years of age.

METHODS

MEDLINE, EMBASE, SCOPUS and PsycINFO were searched for studies reporting the prevalence of symptoms of PSD and/or PSA in young adults with stroke from inception until June 23, 2023. We included studies that evaluated depression and/or anxiety symptoms with screening tools or interviews following ischemic or hemorrhagic stroke. Validated methods were employed to evaluate risk of bias.

RESULTS

4748 patients from twenty eligible studies were included. Among them, 2420 were also evaluated for symptoms of PSA while 847 participants were evaluated for both PSD and PSA symptoms. Sixteen studies were included in the random effects meta-analysis for PSD symptoms, with a pooled prevalence of 31 % (95 % CI 24-38 %). Pooled PSA symptom prevalence was 39 % (95 % CI 30-48 %) and comorbid PSD with PSA symptom prevalence was 25 % (95 % CI 12-39 %). Varying definitions of 'young adult', combinations of stroke subtypes, and methods to assess PSD and PSA contributed to high heterogeneity amongst studies.

CONCLUSIONS

We identified high heterogeneity in studies investigating the prevalence of symptoms of PSD and PSA in young adults, emphasizing the importance of standardized approaches in future research to gain insight into the outcomes and prognosis of PSD and PSA symptoms following stroke in young adults. Larger longitudinal epidemiological studies as well as studies on tailored interventions are required to address the mental health needs of this important population.

Domain-specific cognitive impairments, mood and quality of life 6 months after stroke

PURPOSE

To identify which acute and 6-month domain-specific cognitive impairments impact mood, participation, and stroke-related quality of life 6 months post-stroke.

MATERIALS AND METHODS

A prospective cohort of 430 stroke survivors completed the Oxford Cognitive Screen (OCS) acutely and 6 months post-stroke. Participants completed the Stroke Impact Scale (SIS) and Hospital Depression and Anxiety Scale (HADS) at 6 months. Multivariable regression analyses assessed whether severity of, and domain-specific, cognitive impairment acutely and at 6 months was associated with composite 6-month SIS scores, each SIS subscale, and HADS scores.

RESULTS

Increased severity of acute and 6-month cognitive impairment was associated with lower 6-month SIS composite scores independent of age, sex, education years, and stroke severity (both p < 0.001). Domain-specific impairments in memory (p < 0.001) and attention (p = 0.002) acutely, and language (p < 0.001), memory (p = 0.001) and number processing (p = 0.006) at 6 months showed the strongest associations with worse SIS composite scores. Severity of acute and 6-month cognitive impairment was associated with poorer functioning in each SIS subscale, and greater levels of depression (acute p = 0.021, 6-months p < 0.001), but not anxiety (p = 0.174, p = 0.129).

CONCLUSIONS

Both acute and 6-month domain-specific cognitive impairments, particularly in memory, were found to negatively impact overall functional and mood outcomes 6 months post-stroke.

'Physical well-being is our top priority': Healthcare professionals' challenges in supporting psychosocial well-being in stroke services

BACKGROUND

Following stroke, a sense of well-being is critical for quality of life. However, people living with stroke, and health professionals, suggest that well-being is not sufficiently addressed within stroke services, contributing to persistent unmet needs. Knowing that systems and structures shape clinical practice, this study sought to understand how health professionals address well-being, and to examine how the practice context influences care practice.

METHODS

Underpinned by Interpretive Description methodology, we interviewed 28 health professionals across multiple disciplines working in stroke services (acute and rehabilitation) throughout New Zealand. Data were analysed using applied tension analysis.

RESULTS

Health professionals are managing multiple lines of work in stroke care: biomedical work of investigation, intervention and prevention; clinical work of assessment, monitoring and treatment; and moving people through service. While participants reported working to support well-being, this could be deprioritised amidst the time-oriented pressures of the other lines of work that were privileged within services, rendering it unsupported and invisible.

CONCLUSION

Stroke care is shaped by biomedical and organisational imperatives that privilege physical recovery and patient throughput. Health professionals are not provided with the knowledge, skills, time or culture of care that enable them to privilege well-being within their work. This has implications for the well-being of people with stroke, and the well-being of health professionals. In making these discourses and culture visible, and tracing how these impact on clinical practice, we hope to provide insight into why well-being work remains other to the 'core' work of stroke, and what needs to be considered if stroke services are to better support people's well-being.

PATIENT OR PUBLIC CONTRIBUTIONS

People with stroke, family members and people who provide support to people with stroke, and health professionals set priorities for this research. They advised on study conduct and have provided feedback on wider findings from the research.

The mediating effect of anxiety on the association between residual neurological impairment and post-stroke participation among persons with and without post-stroke depression

Previous research has reported that residual neurological impairment and emotional factors play a role in regaining successful participation post-stroke. The objective of this study was to investigate the mediating impact of anxiety on the association between residual neurological impairment and participation in survivors with and without post-stroke depressive symptoms. Participants (N = 79) were classified into 2 categories, those with post-stroke depressive symptoms (N = 40) and those without post-stroke depressive symptoms (N = 39). Variables measured in this study: residual neurological impairment (NIH Stroke Scale Score), participation (Reintegration to Normal Living Index), depressive symptoms (Patient Health Questionnaire-9), and trait anxiety (State-Trait Anxiety Inventory). A regression-based mediation analysis was conducted for each group of participants. The majority of participants had some level of anxiety. Residual neurological impairment predicted participation in stroke survivors both with (β = -.45, p = .003) and without (β = -.45, p = .004) post-stroke depressive symptoms. Anxiety mediated this relationship in participants with depressive symptoms (β = -.19, 95% CI = -.361 ∼ -.049), but not in participants without depressive symptoms (β = -.18, 95% CI = -.014 ∼ .378). Depressive and anxious symptoms should both be addressed to best facilitate participation by stroke survivors.

Health risk factors in Australian Stroke Survivors: A latent class analysis

ISSUES ADDRESSED

To (i) determine the prevalence of health risk factors (physical activity, diet, alcohol, smoking, blood pressure medication use and mental health) in community-dwelling stroke survivors; and (ii) examine how these health risk factors cluster, and identify associations with physical functioning, independent living, or sociodemographic factors.

METHODS

A secondary analysis of data obtained during a national randomised controlled trial. Participants had experienced stroke and completed a baseline telephone survey on demographic and stroke characteristics, health risk factors, physical functioning and independence in activities of daily living. A latent class analysis was performed to determine health risk profiles. Univariate logistic regressions were performed to identify if participant characteristics were associated with resulting classes.

RESULTS

Data analysed from 399 participants. Two classes of health risk factors were identified: Low Mood, Food & Moves Risk (16% of participants) and Alcohol Use Risk (84% of participants). The Low Mood, Food & Moves Risk group had poorer diet quality, lower physical activity levels and higher levels of depression and anxiety. Lower levels of independence and physical functioning were predictor variables for this group. In contrast, the Alcohol Use Risk group had better physical activity and diet scores, significantly lower probability of depression and anxiety, but a higher probability of risky drinking.

CONCLUSIONS

We identified two distinct health risk factor groups in our population. SO WHAT?: Future interventions may benefit from targeting the specific needs and requirements of people who have experienced stroke based on their distinct risk group. Alcohol consumption in poststroke populations requires further attention.

Effectiveness of group acceptance and commitment therapy in treating depression for acute stroke patients

OBJECTIVES

To date, the effectiveness of acceptance and commitment therapy (ACT) for acute stroke patients has not been well recognized. The study aimed to discover the effectiveness of group-based ACT in treating depression for acute stroke patients.

METHODS

We conducted a randomized controlled trial with 140 acute stroke patients with depression. The ACT intervention comprised seven sessions, of 45-60 min over 4 weeks. Data were collected pre- and post-intervention and at 3-month follow-up, assessing depression, health-related quality of life (HRQoL), psychological flexibility, cognitive fusion, sleep quality, and confidence.

RESULTS

Overall, 99.3% of the included patients were assessed as having mild depression. The ACT intervention significantly reduced depression in acute stroke patients in comparison with the control group post-intervention and at 3 months (partialη 2 = . 306 $\eta^{2}=.306$ ). Additionally ACT significantly improved HRQoL-mental component summary, sleep quality, psychological flexibility, cognitive fusion, and confidence compared with control group.

CONCLUSIONS

ACT is effective in treating acute stroke patients with depression, and the efficacy was maintained at 3-month follow-up.

Long-term psychological outcomes following stroke: the OX-CHRONIC study

BACKGROUND

Stroke survivors rate longer-term (> 2 years) psychological recovery as their top priority, but data on how frequently psychological consequences occur is lacking. Prevalence of cognitive impairment, depression/anxiety, fatigue, apathy and related psychological outcomes, and whether rates are stable in long-term stroke, is unknown.

METHODS

N = 105 long-term stroke survivors (M [SD] age = 72.92 [13.01]; M [SD] acute NIH Stroke Severity Score = 7.39 [6.25]; 59.0% Male; M [SD] years post-stroke = 4.57 [2.12]) were recruited (potential N = 208). Participants completed 3 remote assessments, including a comprehensive set of standardized cognitive neuropsychological tests comprising domains of memory, attention, language, and executive function, and questionnaires on emotional distress, fatigue, apathy and other psychological outcomes. Ninety participants were re-assessed one year later. Stability of outcomes was assessed by Cohen's d effect size estimates and percent Minimal Clinically Important Difference changes between time points.

RESULTS

On the Montreal Cognitive Assessment 65.3% scored < 26. On the Oxford Cognitive Screen 45.9% had at least one cognitive impairment. Attention (27.1%) and executive function (40%) were most frequently impaired. 23.5% and 22.5% had elevated depression/anxiety respectively. Fatigue (51.4%) and apathy (40.5%) rates remained high, comparable to estimates in the first-year post-stroke. Attention (d = -0.12; 85.8% stable) and depression (d = 0.09, 77.1% stable) were the most stable outcomes. Following alpha-adjustments, only perceptuomotor abilities (d = 0.69; 40.4% decline) and fatigue (d = -0.33; 45.3% decline) worsened over one year. Cognitive impairment, depression/anxiety, fatigue and apathy all correlated with worse quality of life.

CONCLUSION

Nearly half of participants > 2 years post-event exhibited psychological difficulties including domains of cognition, mood, and fatigue, which impact long-term quality of life. Stroke is a chronic condition with highly prevalent psychological needs, which require monitoring and intervention development.

Long-term neurological dysfunction associated with COVID-19: Lessons from influenza and inflammatory diseases?

As the COVID-19 pandemic persists, SARS-CoV-2 infection is increasingly associated with long-term neurological side effects including cognitive impairment, fatigue, depression, and anxiety, colloquially known as "long-COVID." While the full extent of long-COVID neuropathology across years or even decades is not yet known, we can perhaps take direction from long-standing research into other respiratory diseases, such as influenza, that can present with similar long-term neurological consequences. In this review, we highlight commonalities in the neurological impacts of influenza and COVID-19. We first focus on the common potential mechanisms underlying neurological sequelae of long-COVID and influenza, namely (1) viral neurotropism and (2) dysregulated peripheral inflammation. The latter, namely heightened peripheral inflammation leading to central nervous system dysfunction, is emerging as a shared mechanism in various peripheral inflammatory or inflammation-associated diseases and conditions. We then discuss historical and modern examples of influenza- and COVID-19-associated cognitive impairment, depression, anxiety, and fatigue, revealing key similarities in their neurological sequelae. Although we are learning that the effects of influenza and COVID differ somewhat in terms of their influence on the brain, as the impacts of long-COVID grow, such comparisons will likely prove valuable in guiding ongoing research into long-COVID, and perhaps foreshadow what could be in store for individuals with COVID-19 and their brain health.

Accelerometer-measured physical activity at 3 months as a predictor of symptoms of depression and anxiety 1 year after stroke: a multicentre prospective cohort study in central Norway

OBJECTIVES

To study sedentary behaviour and physical activity at 3 months as predictors for symptoms of depression and anxiety at 1-year post-stroke.

DESIGN

A prospective cohort study.

PATIENTS

Patients with first-ever ischaemic stroke.

METHODS

Mood was assessed 3- and 12-months post-stroke using the Hospital Anxiety and Depression Scale. Sedentary behaviour and physical activity were measured using accelerometry 3 months post-stroke.

RESULTS

A total of 292 participants (116 (39.7%) females; mean age 71.7 (standard deviation 11.3) years) were included. At 12 months, 16.7% experienced depression and 19.5% anxiety, respectively. Adjusting for age and sex, regression analysis showed that comorbidity burden (β 0.26; 95% confidence interval (95% CI) 0.02, 0.51; p = 0.038), stroke severity (β 0.22; 95% CI 0.10, 0.35; p = 0.001), functional disability (β 0.89, 95% CI 0.49, 1.30; p = 0.000), and global cognition (β-0.15; 95% CI -0.25, -0.05; p = 0.004) predicted depression. Multi-adjusted analysis showed sedentary behaviour and physical activity did not significantly predict depression or anxiety (p > 0.05).

CONCLUSION

Sedentary behaviour and physical activity did not significantly predict mood after stroke. Comorbidity burden, stroke severity, functional disability, and global cognition were identified as possible predictors of depression. More research is needed to determine the impact of physical activity on depression and anxiety symptoms.

Psychological support after stroke: unmet needs and workforce requirements of clinical neuropsychological provision for optimal rehabilitation outcomes

Stroke services must detect and manage psychological and neuropsychological problems that occur after stroke, such as cognitive and language impairments, post-stroke apathy, post-stroke emotionalism, depression, anxiety, post-traumatic stress disorder, personality changes and suicidality. Stroke neuropsychology plays a key role in the assessment, understanding and management of these consequences of stroke, as well as contributing to complex case management, staff supervision and training. Where these provisions are absent from the stroke rehabilitation pathway, this significantly limits potential rehabilitation outcomes. To manage the scale of psychological and neuropsychological needs post stroke, clinical guidance recommends the use of a matched care system, in which these needs are triaged and matched with corresponding levels of support. Recent workforce guidelines provide clear professional recommendations for psychological staffing skill mix and threshold requirements for clinical oversight and clinical governance assurances.

Predicting the relationship between anxiety and health-related quality of life in post-stroke patients: The role of sleep duration

OBJECTIVES

Sleep and psychological disorders are common complaints in stroke survivors. The effectiveness of sleep duration in post-stroke on mental well-being and health outcomes has been reported recently. This study aimed to investigate the mediating effect of sleep duration on the relationship between anxiety and health-related quality of life in Chinese post-stroke; MATERIALS AND METHODS: We conducted a quantitative, cross-sectional study with participants recruited through a multistage, stratified, probability proportional to size sampling method. Anxiety, health-related quality of life, and sleep duration were measured by Zung Self-rating Anxiety Scale, World Health Organization Quality of Life Questionnaire, and a self-administered, structured questionnaire. A multiple linear regression analysis was conducted to identify the association between anxiety, sleep duration, and quality of life. The direct and indirect effects of sleep duration on health-related quality of life was assessed using the bootstrap method via Model 4 (parallel mediation) of SPSS PROCESS macro; RESULTS: A total of 856 post-stroke patients participated in the study, and incidence of anxiety symptom amongst post-stroke was 33.53%. Sleep duration mainly plays partial mediating roles in the relationship between mild-to-moderate anxiety and quality of life in physical, psychological, and environment domains, with sleep duration of 7-8h playing a major role; CONCLUSIONS: A significant relationship among anxiety, sleep duration, and quality of life in post-stroke was found in this study. The sleep duration partially mediated the association between anxiety and quality of life. Suitable prevention methods and early interventions for sleep duration may improve the quality of life for post-stroke anxiety.

Acute stress symptoms 1-2 weeks after stroke predict the subsequent development of post-traumatic stress symptoms: A prospective cohort study

OBJECTIVE

To date no research has examined the potential influence of acute stress symptoms (ASD) on subsequent development of post-traumatic stress disorder (PTSD) symptoms in stroke survivors. Our objective was to examine whether acute stress symptoms measured 1-2 weeks post-stroke predicted the presence of post-traumatic stress symptoms measured 6-12 weeks later.

DESIGN

Prospective within-groups study.

METHODS

Fifty four participants who completed a measure of acute stress disorder at 1-2 weeks following stroke (time 1) and 31 of these participants completed a measure of posttraumatic stress disorder 6-12 weeks later (time 2). Participants also completed measures of stroke severity, functional impairment, cognitive impairment, depression, anxiety, pre-morbid intelligence and pain across both time points.

RESULTS

Some 22% met the criteria for ASD at baseline and of those, 62.5% went on to meet the criteria for PTSD at follow-up. Meanwhile two of the seven participants (28.6%) who met the criteria for PTSD at Time 2, did not meet the ASD criteria at Time 1 (so that PTSD developed subsequently). A hierarchical multiple regression analysis indicated that the presence of acute stress symptoms at baseline was predictive of post-traumatic stress symptoms at follow-up (R2 = .26, p < .01). Less severe stroke was correlated with higher levels of post-traumatic stress symptoms at Time 2 (rho = .42, p < .01).

CONCLUSIONS

The results highlight the importance of early assessment and identification of acute stress symptoms in stroke survivors as a risk factor for subsequent PTSD. Both ASD and PTSD were prevalent and the presence of both disorders should be assessed.

Factors Associated With Anxiety After Hemorrhagic Stroke

OBJECTIVE

A significant number of patients develop anxiety after stroke. The objective of this study was to identify risk factors for anxiety after hemorrhagic stroke that may facilitate diagnosis and treatment.

METHODS

Patients admitted between January 2015 and February 2021 with nontraumatic hemorrhagic stroke (intracerebral [ICH] or subarachnoid [SAH] hemorrhage) were assessed telephonically 3 and 12 months after stroke with the Quality of Life in Neurological Disorders Anxiety Short Form to evaluate the relationships between poststroke anxiety (T score >50) and preclinical social and neuropsychiatric history, systemic and neurological illness severity, and in-hospital complications.

RESULTS

Of 71 patients who completed the 3-month assessment, 28 (39%) had anxiety. There was a difference in Glasgow Coma Scale (GCS) scores on admission between patients with anxiety (median=14, interquartile range [IQR]=12-15) and those without anxiety (median=15, IQR=14-15) (p=0.034), and the incidence of anxiety was higher among patients with ICH (50%) than among those with SAH (20%) (p=0.021). Among patients with ICH, anxiety was associated with larger median ICH volume (25 cc [IQR=8-46] versus 8 cc [IQR=3-13], p=0.021) and higher median ICH score (2 [IQR=1-3] versus 1 [IQR=0-1], p=0.037). On multivariable analysis with GCS score, hemorrhage type, and neuropsychiatric history, only hemorrhage type remained significant (odds ratio=3.77, 95% CI=1.19-12.05, p=0.024). Of the 39 patients who completed the 12-month assessment, 12 (31%) had anxiety, and there was a difference in mean National Institutes of Health Stroke Scale scores between patients with (5 [IQR=3-12]) and without (2 [IQR=0-4]) anxiety (p=0.045). There was fair agreement (κ=0.38) between the presence of anxiety at 3 and 12 months.

CONCLUSIONS

Hemorrhage characteristics and factors assessed with neurological examination on admission are associated with the development of poststroke anxiety.

Disagreement about perceptions of patient disability between the stroke patient and caregiver: a cross sectional study exploring the association to patient and caregiver quality of life

OBJECTIVES

This study explored the association of disagreement in the perception of patient disability between patients and family caregivers with physical and psychological quality of life (QOL) in both parties.

METHODS

A cross-sectional analysis of data collected from male stroke patients and family caregivers was conducted. Physical and psychological QOL in patients and caregivers were measured using the WHOQOL BREF. Perceptions of patient disability were measured using the 12-item WHO Disability Assessment Schedule 2.0 (DAS). Using DAS scores reported independently by patients and caregivers, dyads were categorized into one of four groups representing agreement or disagreement about patient disability. Generalized estimating equations were used to examine the associations between WHOQOL scores in patients and caregivers and these four groups.

RESULTS

Among 56 dyads enrolled, approximately 52% were categorized into 'agreement' groups and 48% were categorized into 'disagreement' groups. The disagreement in perception about patient disability were significantly associated with poor patient physical QOL. However, the disagreement in perception were not significantly associated with caregiver QOL.

CONCLUSION

Findings suggest the association of disagreement with QOL differs between patients and caregivers. Further research is needed to carefully appraise the relationship and interaction between patient and caregiver.

Evaluation & Treatment of Psychological Effects of Stroke

Strokes are a common medical condition in the United States, including in Delaware. An under-recognized effect of stroke is the impact on mood that often occurs. Many individuals develop depression, anxiety, PTSD, and other psychological sequelae. These disorders can significantly affect their lives and their relationships. The emotional effects of stroke pose a public health problem for our residents, leading to devastating decreases in the quality of life for the patient and the family. These challenges negatively impact the community due to the associated healthcare and economic burdens. The population of the State of Delaware is growing, and the proportion of senior residents, who are also at greater risk for strokes, is also increasing. Strokes will remain an ongoing important clinical concern for our healthcare providers. Emotional changes after a stroke will occur in many Delaware residents who suffer a stroke. The emotional sequelae of stroke are under-treated. It is critical for healthcare professionals to be trained to recognize, assess, and treat the psychological disorders that can result from having a stroke. This article provides an overview of the major psychological effects of stroke, recommended assessment tools, promising treatment trends, and directions for further research. Improving our ability to detect and treat these difficult emotional challenges can facilitate effective treatment and prevention strategies and increase quality of life for stroke survivors, their loved ones, and their communities.

Interventions for improving psychosocial well-being after stroke: A systematic review

BACKGROUND

Up to one third of all stroke patients suffer from one or more psychosocial impairments. Recognition and treatment of these impairments are essential in improving psychosocial well-being after stroke. Although nurses are ideally positioned to address psychosocial well-being, they often feel insecure about providing the needed psychosocial care. Therefore, we expect that providing nurses with better knowledge to deliver this care could lead to an improvement in psychosocial well-being after stroke. Currently it is not known which interventions are effective and what aspects of these interventions are most effective to improve psychosocial well-being after stroke.

OBJECTIVE

To identify potentially effective interventions - and intervention components - which can be delivered by nurses to improve patients' psychosocial well-being after stroke.

METHODS

A systematic review and data synthesis of randomized controlled trials and quasi experimental studies was conducted. Papers were included according to the following criteria: 1) before-after design, 2) all types of stroke patients, 3) interventions that can be delivered by nurses, 4) the primary outcome(s) were psychosocial. PubMed, Embase, PsychInfo, CINAHL and Cochrane library were searched (August 2019-April 2022). Articles were selected based on title, abstract, full text and quality. Quality was assessed by using Joanna Briggs Institute checklists and a standardized data extraction form developed by Joanna Brigss Institute was used to extract the data.

RESULTS

In total 60 studies were included, of which 52 randomized controlled trials, three non-randomized controlled trials, four quasi-experimental studies, and one randomized cross-over study. Nineteen studies had a clear psychosocial content, twenty-nine a partly psychosocial content, and twelve no psychosocial content. Thirty-nine interventions that showed positive effects on psychosocial well-being after stroke were identified. Effective intervention topics were found to be mood, recovery, coping, emotions, consequences/problems after stroke, values and needs, risk factors and secondary prevention, self-management, and medication management. Active information and physical exercise were identified as effective methods of delivery.

DISCUSSION

The results suggest that interventions to improve psychosocial well-being should include the intervention topics and methods of delivery that were identified as effective. Since effectiveness of the intervention can depend on the interaction of intervention components, these interactions should be studied. Nurses and patients should be involved in the development of such interventions to ensure it can be used by nurses and will help improve patients' psychosocial well-being.

Rehabilitation in Animal Models of Stroke

OBJECTIVE

The purpose of this review was to evaluate the efficacy of rehabilitation strategies in animal models of stroke and their correlation with human stroke studies.

METHODS

General description of a stroke, functional recovery, and rehabilitation modalities were included from published studies in the field of animal models of cerebral ischemia and ischemia-reperfusion.

RESULTS

In stroke survivors, rehabilitation plays a significant role to improve motor function, cognition, and other subtle behaviors. Targeted pharmacological agents, including neuroprotective drugs, are helpful in animal models of stroke. However, no drug has yet been found that meets the criteria that would make it the Food and Drug Administration-approved treatment for human stroke. Instead, the rehabilitation of stroke in humans is limited to physical and occupational therapy, speech therapy, environmental enrichment, and social activities, as well as spiritual and family support.

CONCLUSION

Studies on stroke injury and the significance of stroke animals' rehabilitation, including physical and pharmacological, approaches are highlighted.

Association between obstructive sleep apnea and risk for post-stroke anxiety: A Chinese hospital-based study in noncardiogenic ischemic stroke patients

OBJECTIVE

This study explored the role of obstructive sleep apnea (OSA) in post stroke anxiety (PSA) in noncardiogenic ischemic stroke patients.

METHODS

180 patients with noncardiogenic ischemic stroke were consecutively enrolled from January 2019 to December 2019. All patients underwent polysomnography (PSG) to assess for OSA. OSA severity was identified based on the apnea hypopnea index (AHI), i.e., no OSA (AHI <5), mild OSA (5 = AHI <15), and moderate to severe OSA (AHI ≥15). Neuropsychological assessments were performed at acute phase and 6 months later to evaluate anxiety (Chinese version of the Zung self-rating anxiety scale [SAS], and Beck Anxiety Inventory [BAI]), depression (Patient Health Questionnaire-9, [PHQ-9]), and cognition (Mini-mental state examination, [MMSE], and Montreal Cognitive Assessment, [MOCA]). Clinical diagnoses of PSA were made based on interviews and the anxiety scales. The correlations between PSA and OSA were investigated in Logistic regression analysis.

RESULTS

The prevalence of acute-phase and 6-month PSA were 27 (15%) and 52 (28.9%) respectively. Moderate to severe OSA and post-stroke depression (PSD) were the influencing factors of acute-phase PSA. 6-Month PSA was not associated with OSA but was associated with acute-phase anxiety, education status and MOCA. Logistic regression analysis including respiratory and sleeping parameters showed that AHI and micro-arousal index contributed to acute-phase PSA.

CONCLUSIONS

Acute-phase PSA was associated with OSA severity, potentially through OSA-caused sleep discontinuity. While 6-month PSA was associated with acute-phase anxiety, highlighting the need for integration of screening for and management of OSA and PSA at acute phase.

Activation of CREB-BDNF Pathway in Pyramidal Neurons in the Hippocampus Improves the Neurological Outcome of Mice with Ischemic Stroke

Cerebral ischemia is characterized by several pathological reaction evolving over time. Hyperactivation of glutamatergic neurons is the main factor leading to excitotoxicity which potentiates oxidative stress and triggers the mechanisms of neural apoptosis after cerebral ischemia. However, it is unclear whether glutamate in the ventral hippocampal Cornus Ammonis 1 (vCA1) acts a part in neurological deficits, pain perception, anxiety, and depression induced by ischemic stroke. We investigated the effects of chemogenetic inhibition or activation of vCA1 pyramidal neurons which are mainly glutamatergic neurons on sequelae induced by cerebral ischemia. Our results revealed that inhibition of vCA1 pyramidal neurons by chemogenetics alleviated neurological deficits, pain perception, anxiety, and depression caused by cerebral ischemia in mice, but activation of vCA1 pyramidal neurons had limited effects. Moreover, we found that stroke was accompanied by decreased levels of cAMP-response element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF) in vCA1, which are modulated by glutamate. In this study, overexpression of CREB protein in pyramidal neurons in vCA1 by AAV virus significantly upregulated the content of BDNF and ameliorated the dysfunction induced by ischemic stroke. Our results demonstrated activation of the CREB-BDNF pathway in vCA1 pyramidal neurons significantly improved neurological deficits, pain perception, anxiety, and depression induced by ischemic stroke.

Identifying emotional contributors to participation post-stroke

BACKGROUND

Participation in daily activities is the ultimate goal of stroke rehabilitation. Emotional factors have been considered as contributors to participation, but associations between emotional factors and participation post-stroke have not been fully explored.

OBJECTIVE

To investigate the extent to which emotional factors contribute to participation post-stroke.

METHODS

73 participants were included. Three participation outcomes were used as dependent variables in three models: (1) Stroke Impact Scale (SIS) Participation/Role Function, (2) Activity Card Sort (ACS), and (3) Reintegration to Normal Living (RNL). Main independent variables were six emotional factors: SIS Emotion Function (General emotion), Visual Analog Mood Scale energetic and happy subscales, Patient Health Questionnaire-9 (Depression), State-Trait Anxiety Inventory-Trait Anxiety Scale, and Apathy Evaluation Scale. Covariates of stroke severity and social support were included.

RESULTS

Model 1 showed stroke severity (β = -0.300) and depression (β = -0.268) were significant contributors to SIS Participation/Role Function (R² = 0.368, p < .05). Model 2 indicated that happiness (β = 0.284) and apathy (β = -0.330) significantly contributed to ACS total activity retention (R² = 0.247, p < .05). Model 3 revealed that anxiety (β = -0.348), apathy (β = -0.303), stroke severity (β = -0.184), and social support (β = 0.185) were significant contributors to RNL total score (R² = 0.583, p < .05).

CONCLUSIONS

Results suggested that emotional measures of apathy, depression, anxiety, and happiness, but not general emotion, were important contributors to participation post-stroke. These findings suggest that rehabilitation professionals should address individual emotional contributors to facilitate participation post-stroke.

Personalized Biomarkers and Neuropsychological Status Can Predict Post-Stroke Fatigue

Post-stroke fatigue (PSF) is a common complication of stroke that has a negative impact on prognosis and recovery. We aimed to investigate the relationship between PSF and demographics, mood disorders, sleep disorders, and other clinical characteristics of patients with stroke. In this exploratory cross-sectional study, we collected data on sociodemographic characteristics, biological indicators, and imaging features and evaluated patients using neuropsychological scales. Patients were assessed using the Fatigue Severity Scale, Hamilton Depression Rating Scale, Hamilton Anxiety Scale, and Pittsburgh Sleep Quality Index. Magnetic resonance imaging scans were primarily used to evaluate infarctions and white matter lesions. The correlation between the PSF of patients with stroke and clinical indicators was obtained by logistic regression analysis and power analysis. We observed an independent association between fatigue severity and female sex (odds ratio [OR], 2.12; 95% confidence interval [CI], 1.14-3.94), depressive state (OR, 1.50; 95% CI, 1.01-1.73), and sleep disorders (OR, 1.58; 95% CI, 1.01-1.98). High levels of blood glucose, serum uric acid, and homocysteine and low levels of serum triiodothyronine were strongly associated with poor functional outcomes in patients with stroke. Further studies are needed to elucidate how specific structural lesions and anxiety symptoms are related to early PSF.

"I Assumed It Would Be Somebody Who Had a Stroke That Was Doing This": Views of Stroke Survivors, Caregivers, and Health Professionals on Tailoring a Relaxation and Mindfulness Intervention

Stroke survivors and informal caregivers experience high levels of stress and anxiety, linked to heightened risk of secondary stroke in survivors. Relaxation and mindfulness could reduce stress and anxiety; being most effective when tailored to the target populations. Aims of the PPI include to: (1) consult on possible alterations to an existing relaxation and mindfulness intervention, delivered via YouTube/DVD and (2) discuss relevance and preference of prompts and cues designed to facilitate the daily practice of the intervention. Eleven UK PPI contributors were consulted during 2020: four stroke survivors (F = 2, M = 2), three caregivers (F = 1, M = 2), and four HCPs (F = 4) (range = 23-63 years). Contributors watched the existing intervention and provided feedback via online discussions. Transcripts were analysed using thematic analysis. Five themes were identified, highlighting several necessary alterations to the intervention: "Who represents the stroke population?"; "The paradox of age"; "Specifically selected language"; "Visual presentation of the intervention"; and the "Audio qualities". Contributors ranked the prompts and cues in order of preference with setting alarms and email alerts as the most popular. The PPI consultations resulted in several alterations enabling a revised version of the intervention. Including a PPI consultation at an early stage of the research improves the relevance and appropriateness of the research. The revised intervention is more representative of the stroke population thus more likely to be practised by survivors and caregivers, which will enhance the extent of effectiveness, reducing the risk of a secondary stroke.

The HEADS: UP Development Study: Working with Key Stakeholders to Adapt a Mindfulness-Based Stress Reduction Course for People with Anxiety and Depression after Stroke

BACKGROUND

Following stroke, rates of mood disorder are and remain high at five years (anxiety 34.4%; depression 23%). Structured mindfulness-based stress reduction (MBSR) courses are effective in a range of health conditions, but stroke survivors find adherence challenging. We aimed to adapt a standard MBSR course specifically for people affected by stroke.

METHODS

We recruited stroke survivors and family members with symptoms of anxiety and/or depression to take part in a co-development study comprising two rounds of MBSR 'taster' sessions, followed by focus groups in which views were sought on the practices sampled. Data were collected in October 2017 and May 2018 and were analysed using framework analysis, informed adaptations to mindfulness materials and delivery.

RESULTS

Twenty-eight stroke survivors and seven family members participated. Nineteen (76%) stroke survivors had anxiety; 15 (60%) had depression. Five (71.4%) family members reported anxiety; n = 4 (57.1%) depression. Thirty participants attended the first round of taster sessions and focus groups; twenty (66%) the second and three (10%) were unable to attend either round. Framework analysis informed adaptations to course delivery, practices, and materials, ultimately resulting in a stroke-specific MBSR course, HEADS: UP (Helping Ease Anxiety and Depression after Stroke).

CONCLUSIONS

HEADS: UP may provide a feasible, appropriate, and meaningful self-management intervention to help alleviate symptoms of mood disorder.

Prevalence of anxiety and depression symptoms in a sample of outpatients with ATTR cardiac amyloidosis

Patients with ATTR cardiac amyloidosis (ATTR-CA) face rare disease that could negatively influence psychological well-being with consequences on the course of the disease and quality of life. However, to date, no study analyzed the prevalence of anxiety and depression in patients with ATTR-CA and which clinical and sociodemographic characteristics are linked with these psychopathological conditions. A total of 109 consecutive patients (83% males) aged 62-90 years with ATTR-CA were recruited. In order to better understand the prevalence of anxiety and depression in ATTR-CA, a control group composed by 33 individuals equaling gender, education, and age were recruited. The level of anxiety and depression was measured using the Italian version of the Hospital Anxiety and Depression Scale (HADS). Sociodemographic and clinic characteristics were registered. Almost half of patients (49%) reported a clinical level of depression or anxiety, or both. ATTR-CA patients reported higher levels of anxiety and depression than control group. Results showed that older patients with ATTR-CA, especially females, with more advanced disease could be more at risk to develop an anxious disorder. Furthermore, being a woman, and presenting with a greater severity of symptoms, would appear to be a risk factor for developing a depressive disorder. Overall, these results highlighted the high presence of anxiety and depression in ATTR-CA patients, suggesting to physicians to pay attention to the psychological well-being of ATTR-CA patients. In fact, a psychological support for patients with high level of psychopathological disease could reduce disease burden and improve quality of life in ATTR-CA population.

Determinants of post-stroke depression among stroke survivors at University of Gondar Hospital, Northwest Ethiopia: a case-control study

BACKGROUND

Stroke is one of the most common causes of disability among adults. Post-stroke depression (PSD) is a frequent neuropsychiatric complication in stroke patients. Despite the increasing prevalence of stroke, there is a paucity of data on PSD and its determinants among stroke survivors in developing countries like Ethiopia. We aim to assess the factors associated with PSD in survivors of stroke.

METHOD

A hospital-based unmatched case-control study was conducted during the period of February to July 2020 at University of Gondar Hospital among stroke survivors. Study subjects were recruited consecutively. Socio-demographic and clinical data were obtained from patients' interviews and medical record reviews. A diagnosis of PSD was made using the Patient Health Questionnaire (PHQ-9). EpiData version 3.1 was used to enter data, and SPSS version 26 was used to analyze it. Bivariate and multivariate logistic regressions were fitted to identify associated variables. The adjusted odds ratio (AOR) with 95% confidence interval (CI) and p-value 0.05 were used to determine the significance of the association.

RESULT

A total of 240 stroke survivors were included in the study (80 cases and 160 controls). The mean age was 60.8 years (SD ± 14.3) with an equal sex distribution. Variables statistically associated with PSD were male gender (AOR = 3.5, 95% CI: 1.64-7.46 C, P-value = 0.001), subcortical location of the largest lesion (AOR = 2.42, 95% CI: 1.06-5.56, p-value = 0.036), severity of the stroke (AOR = 52.34, 95% CI:10.64-256.87, p-value = 0.000), physical disability (AOR = 5.85. 95% CI:1.94-17.65, p-value = 0.002), previous history of stroke or transient ischemic attack (AOR = 5.90, 95% CI:2.04-17.10, p-value = 0.001) and ischemic heart disease (AOR = 9.97, 95% CI:3.4-29.22, p-value = 0.000).

CONCLUSION

Important factors in the occurrence of PSD in this study include prior history of stroke, physical disability, severity of the stroke, subcortical location of the lesion, male gender, and ischemic heart disease. Stroke patients with such factors need routine screening for PSD, particularly in LMICs where there is uncoordinated post-stroke care, a shortage of neurologists and mental health practitioners.

Post-stroke emotionalism (PSE): a qualitative longitudinal study exploring individuals' experience with PSE

PURPOSE

Post-stroke emotionalism (PSE) is a common consequence of stroke characterised by episodes of crying or laughing. There is only one published qualitative study exploring the experience of emotionalism to date. This study aimed to explore individual's experience of PSE and develop a theoretical client-derived framework to shape future psychological interventions.

MATERIALS AND METHODS

A primary analysis of the qualitative pseudonymised pre-collected semi-structured interview data of the TEARS study was completed. Participants were recruited from nine acute stroke units in Scotland with participants commencing the study at baseline (two-weeks) and they either continued or dropped out. Interviews were completed at two-weeks, six-months and 12-months post-stroke.

RESULTS

Data was analysed from 52 participants at two-weeks, 25 participants at six-months and 23 participants at 12-months. Three major themes were identified: "In the moment," describing characteristics and triggers, "Ways of coping," highlighted a variation of coping strategies including avoidance or acceptance and "Impact," outlining the longer-term effects of PSE such as individuals' beliefs.

CONCLUSION

The results indicate specific psychological aspects of PSE which could be viable targets in psychological interventions such as increasing adaptive coping strategies and challenging negatively held beliefs.IMPLICATIONS FOR REHABILITATIONEmotionalism can cause emotional consequences such as distress, embarrassment and fear.Helping individuals to develop insight into triggers for emotionalism could be beneficial to help gain understanding and awareness whereby post-stroke emotionalism (PSE) has the potential to be anticipated and adapted to psychologically.Potential adaptive responses such as acceptance or control and better anticipation of episodes of emotionalism could help to reduce the emotional consequences of PSE.

Self-reported cognitive and psychiatric symptoms at 3 months predict single-item measures of fatigue and daytime sleep 12 months after ischemic stroke

Introduction

Post-stroke fatigue and increased need for daytime sleep are multidimensional and insufficiently understood sequelae. Our aim was to study the relationships of self-reported cognitive and psychiatric symptoms at 3 months with fatigue and daytime sleep at 12 months post-stroke.

Methods

Ischemic stroke patients without reported history of dementia or depression completed postal surveys 3- and 12-months post-stroke. At 3 months, psychiatric symptoms were assessed with the Hospital Anxiety and Depression Scale (HADS), and self-reported changes in cognitive symptoms (concentration and memory) compared to pre-stroke were assessed using single-item measures. At 12 months, single-item questions about changes in self-reported difficulties sleeping at night, fatigue and daytime sleep were included. First, we studied whether self-reported cognitive and/or psychiatric symptoms at 3 months were associated with daytime sleep and fatigue at 12 months using multiple logistic regression. Second, we fitted 2 structural equation models (SEMs) predicting fatigue and 2 models predicting daytime sleep. We compared a model where only age, sex, stroke severity (National Institutes of Health Stroke Scale; NIHSS), and difficulties sleeping at night predicted fatigue and daytime sleep at 12 months to a model where mental distress (i.e., a latent variable built of cognitive and psychiatric symptoms) was included as an additional predictor of fatigue and daytime sleep at 12 months.

Results

Of 156 patients (NIHSS within 24 hours after admission (mean ± SD) = 3.6 ± 4.3, age = 73.0 ± 10.8, 41% female) 37.9% reported increased daytime sleep and 50.0% fatigue at 12 months. Increased psychiatric symptoms and worsened cognitive symptoms were associated with fatigue and daytime sleep at 12 months, after controlling for NIHSS, age, sex, and difficulties sleeping at night. SEM models including mental distress as predictor showed adequate model fit across 3 fit measures (highest RMSEA = 0.063, lowest CFI and TLI, both 0.975). Models without mental distress were not supported.

Conclusion

Self-reported cognitive and psychiatric symptoms at 3 months predict increased daytime sleep and fatigue at 12 months. This highlights the relevance of monitoring cognitive and psychiatric symptoms in the subacute phase post-stroke. However, future research using validated measures of self-reported symptoms are needed to further explore these relationships.

Online Mindfulness with Care Partnerships Experiencing Anxiety and Depression Symptoms after Stroke: Mixed Methods Case Study Research

Purpose: To investigate the experience and outcomes for care partnerships (e.g., spouses, caregivers) who have post-stroke anxiety and/or depression symptoms and used an online mindfulness-based intervention (MBI) together. Design: Explanatory sequential mixed methods case study research. Methods: 5 care partnerships (10 participants) received online MBI, and data was collected in weeks 0, 4, and 8. Data collection involved the Hospital Anxiety Depression Scale, the Mutuality Scale, the Mindful Attention Awareness Scale, and post-intervention interviews. Clinical effectiveness was evaluated using minimal clinically important difference (MCID). Findings: Participants improved mindfulness (80%) and mutuality (30%). MCID was achieved for anxiety symptoms (50%) and depression symptoms (20%). IPA found evidence of conflicting and contradictory experiences so dialectical tension was used to articulate the continuum of perspectives and themes produced in the analysis. Conclusion: Care partnerships using online MBIs can experience improvements in mindfulness, mutuality, anxiety symptoms, and depression symptoms. The findings are complex but show the potential value of online MBI for some care partnerships living with stroke.

The longitudinal course of anxiety, depression and apathy through two years after stroke

OBJECTIVE

Estimate the prevalence of anxiety disorders, depressive disorders and apathy two years after stroke, examine their longitudinal course, describe the course of psychological distress through two years after stroke, and evaluate Hospital Anxiety and Depression Scale HADS-A and HADS-D cut-off scores of ≥4 and ≥ 8 for detection of anxiety and depressive disorders two years after stroke.

METHODS

In a longitudinal cohort study of 150 consecutive stroke patients in a stroke unit, 103 were assessed four months and 75 two years after stroke. Anxiety and depression disorders and symptoms were assessed by the Structured Clinical Interview for DSM-IV and HADS, apathy by the Apathy Evaluation Scale.

RESULTS

Prevalence of at least one anxiety disorder or one depressive disorder decreased from four months to two years (23% vs 9%, P = 0.026, 19% vs 10%, P = 0.17). Apathy remained stable at 48% vs 50%. After two years, 80%, 79% and 19% of those with anxiety, depression or apathy at four months had recovered. Recovery-rates among patients with anxiety were 83% for panic disorder, 60% for generalized anxiety disorder (GAD), and 50% for social phobia.

CONCLUSIONS

In contrast to apathy, recovery from anxiety and depression was high. About half of the patients with GAD, social phobia or agoraphobia did not recover. Co-morbid depression and apathy at four months implied a high risk for not recovering at two years. HADS-A and HADS-D cut-off scores of ≥8 were feasible for detection of anxiety and depression disorders two years after stroke.

Prevalence of depression and its associated factors among stroke survivors in Saudi Arabia

AIM

The purpose of this study was to investigate the prevalence of poststroke depression (PSD) in Saudi Arabia and its association with socio-demographic and clinical factors.

DESIGN

A predictive correlational cross-sectional study.

METHODS

The study adopted a non-probability convenience sampling method to recruit 211 stroke survivors between April and October 2021 from the neurology outpatient departments of two main governmental hospitals in Saudi Arabia. PSD was measured using a self-assessment reliable and valid scale (The Hospital Anxiety and Depression Scale [HADS]).

RESULTS

More than two-thirds (70.6%) of the study sample (Mean age = 53 years, SD = 8.5, 51.2% were males) experienced some degree of depression (Score ≥8); of these, approximately half (48.8%) were in severe depression. The final prediction model was statistically significant (χ₂ [15] = 31.39, p ˂ .01). PSD is a statistically significant health issue and requires immediate attention by healthcare providers to improve the health outcomes of stroke survivors.

State of the Science: The Relevance of Symptoms in Cardiovascular Disease and Research: A Scientific Statement From the American Heart Association

Symptoms of cardiovascular disease drive health care use and are a major contributor to quality of life. Symptoms are of fundamental significance not only to the diagnosis of cardiovascular disease and appraisal of response to medical therapy but also directly to patients' daily lives. The primary purpose of this scientific statement is to present the state of the science and relevance of symptoms associated with cardiovascular disease. Symptoms as patient-reported outcomes are reviewed in terms of the genesis, manifestation, and similarities or differences between diagnoses. Specifically, symptoms associated with acute coronary syndrome, heart failure, valvular disorders, stroke, rhythm disorders, and peripheral vascular disease are reviewed. Secondary aims include (1) describing symptom measurement methods in research and application in clinical practice and (2) describing the importance of cardiovascular disease symptoms in terms of clinical events and other patient-reported outcomes as applicable.

Post-stroke Anxiety Among Patients in Jordan: A Multihospital Study

This study aimed to assess the prevalence, correlates, and significant associated factors of anxiety among patients with stroke. A cross-sectional, correlation design was utilized. The Hospital Anxiety and Depression scale was used to detect and assess the severity of anxiety and depression among mentally well patients at general hospital settings. Among the 226 patients with stroke, 45.6% had clinically significant levels of anxiety to be considered as a definite case. Having a short duration since the stroke onset, being a definite case of depression, being unable to perform self-care activities, having an insufficient monthly income, and having visual problems due to stroke were the significantly associated factors. The high prevalence of anxiety among patients with stroke highlights the need for interventions of early detection and management to enhance recovery. Patients who have any of the significant traits predicted post-stroke anxiety required special attention.

Effectiveness of interventions to support the transition home after acute stroke: a systematic review and meta-analysis

Background

Effective support interventions to manage the transition to home after stroke are still mostly unknown.

Aim

The purpose of this systematic review was to investigate the effectiveness of support interventions at transition from organised stroke services to independent living at home.

Methods

The Cochrane Central Register of Controlled Trials, six databases including MEDLINE and Embase, trial registries, grey literature, and Google Scholar were all searched, up to June 2021.

We included randomised controlled trials enrolling people with stroke to receive either standard care or any type of support intervention from organised stroke services to home. The primary outcome was functional status.

Two authors determined eligibility, extracted data, evaluated risk of bias (ROB2), and verified the evidence (GRADE). Where possible we performed meta-analyses using Risk Ratios (RR) or Mean Differences (MD).

Results

We included 17 studies. Support interventions led to important improvements in functional status, as determined by the Barthel Index up, to 3-months (MD 7.87 points, 95%CI:6.84 to 19.16; 620 participants; five studies; I2 = 77%). Results showed modest but significant functional gains in the medium to long-term (6–12 month follow up, MD 2.91 points, 95%CI:0.03 to 5.81; 1207 participants; six studies; I2 = 84%). Certainty of evidence was low.

Support interventions may enhance quality of life for up to 3-months (MD 1.3,95% CI:0.84 to 1.76), and reduce depression (SMD -0.1,95% CI:-0.29 to − 0.05) and anxiety (MD -1.18,95% CI:-1.84 to − 0.52) at 6–12 months. Effects on further secondary outcomes are still unclear.

Conclusions

Incorporating support interventions as people who have experienced a stroke transition from hospital to home can improve functional status and other outcomes. Due to study heterogeneity, the essential components of effective transition of care interventions are still unknown. Adoption of core outcome sets in stroke research would allow for greater comparison across studies. Application of a development and evaluation framework engaging stakeholders would increase understanding of priorities for stroke survivors, and inform the key components of an intervention at transition from hospital-to-home.

Systematic Review of Existing Stroke Guidelines: Case for a Change

Methods

We systematically searched for guideline recommendation on the day-to-day use of peripheral inflammatory markers such as NLR published in the English language between January 1, 2005, and October 2020. Any other evidence of system biology-based approach or recommendation was explored within the selected guidelines for this scoping review. Only the latest guideline per writing group was selected. Each guideline was analyzed independently by 2 to 4 authors to determine clinical scenarios explained/given, scientific evidence used, and recommendations presented in the context of system biology.

Results

The scoping review found 2,911 titles at the beginning of the search. Final review included with 15 guidelines. Stroke-related organizations wrote sixty-five percent of the guidelines while national ministries wrote a fewer number of guidelines. We were primarily interested in recommendations for acute management in AIS published in the English language. Fifteen eligible guidelines were identified from 15 different countries/regions. None of the guidelines recommended the routine use of peripheral markers of inflammation, such as NLR, among their acute assessment and management recommendations. None of the existing guidelines explored the system biology approach to one of the most complex diseases affecting the human brain, stroke.

Conclusions

This systematic review has identified a significant evidence-practice gap in all existing national stroke guidelines published in English medium as of October 2020. These guidelines included the only current “living stroke guidelines,” stroke guidelines from Australia with a real opportunity to modernize the living stroke guidelines with systems biology approach, and provide 2020 vision towards better stroke care globally. Investigation of complex disease such as stroke is best served through a systems biology approach. One of the easiest places to start is simple blood tests such as total white cell count and NLR. Systems biology approach point us towards simple tools such immune-inflammatory index (SII) and serial systemic immune inflammatory indices (SSIIi) which should pave the way for the stroke physician community address the challenges in systems biology approach in stroke care. These challenges include translating bench research to the bedside, managing big data (continuous pulse, blood pressure, sleep, oxygen saturation, progressive changes in NLR, SII, SSIIi, etc.). Working with an interdisciplinary team also provides a distinct advantage. Recent adoption of historic WHO-IGAP calls for immediate action. The 2022 World Brain Day campaign on Brain Health for All is the perfect opportunity to raise awareness and start the process.

Association between post-stroke psychological disorders, activity limitations and health-related quality of life in chronic stroke survivors in Benin

PURPOSE

To evaluate the association between depression/anxiety and activity limitations and health-related quality of life (HRQoL) in chronic stroke survivors in Benin.

MATERIALS AND METHODS

One hundred and seventy-six chronic stroke survivors (113 males; mean age (±SD): 56.5 (±10.5) years old) were included. We used the Barthel index (BI) to assess activity limitations. Participants were screened for depression and anxiety symptoms using Hamilton Depression Rating Scale (HDRS) and Hamilton Anxiety Rating Scale (HARS). Euroqol-5 Dimensions-3 Levels (EQ-5D-3L) including a Visual Analog Scale (EQ-VAS) was used to assess HRQoL. Multivariate linear regressions were performed to determine the impact of psychological disorders on activity limitations and HRQoL.

RESULTS

Depression (β=-0.54; p < 0.0001) and anxiety (β=-0.35; p < 0.0001) were negatively associated with activity limitations (R²=0.60). Similar patterns of association were observed with HRQoL (β≤-0.28; p < 0.0001; R² ≥0.40). Inversely, occupational status showed positive association with EQ-5D-3L summary index scores (β = 0.21; p = 0.015).

CONCLUSIONS

Depression and anxiety had a negative impact on activity limitations and HRQoL in Beninese chronic stroke survivors. This call for action to integrate psychological interventions as part of rehabilitation programs in low and middle-income countries.Implications for rehabilitationPost-stroke depression and anxiety are quite common among stroke survivors in sub-Saharan Africa.Post-stroke depression and anxiety negatively impact activities and health-related quality of life in chronic stroke survivors in sub-Saharan Africa.Managing these post-stroke psychological disorders is necessary to promote the functional recovery and social reintegration of stroke survivors in their communities.

Effects of a nurse-led peer support intervention for stroke survivors: protocol for a randomised controlled trial

INTRODUCTION

Many stroke survivors have unmet psychosocial needs during the recovery phase following a stroke. There is emerging evidence that peer support interventions may play a valuable role in managing stroke. However, evidence regarding the effectiveness of peer support interventions on the psychosocial outcomes of stroke survivors is uncertain. This study aims to develop a nurse-led peer support intervention for stroke survivors based on the Person-Environment-Occupation-Performance Model and evaluate its effects on the psychosocial outcomes of stroke survivors.

METHODS AND ANALYSIS

This is an assessor-blinded two-arm randomised controlled trial. A convenience sample of 120 stroke survivors will be recruited from two community centres and one rehabilitation unit in Yangzhou, a medium-sized city in eastern China, with 60 participants each in the intervention and control groups. The participants allocated to the intervention group will receive the nurse-led peer support intervention, which includes 6 weekly peer support sessions facilitated by a nurse and at least one peer facilitator. Participants randomised to the control group will receive the same dose of interpersonal interaction as intervention participants, including weekly individual face-to-face session for 6 weeks. The primary outcomes are social participation and participation self-efficacy. The secondary outcomes are psychosocial distress, social support, stigma towards disease, self-efficacy in managing chronic conditions and quality of life. Data will be collected at baseline, immediately after the intervention and 3 months after the intervention. A process evaluation will be conducted qualitatively and quantitively to examine the mechanism by which the intervention impacts the psychosocial outcomes of stroke survivors. All outcomes will be analysed following the intention to treat principle. Generalised Estimation Equation models will be used to assess the intervention effect.

ETHICS AND DISSEMINATION

This protocol was approved by the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (CREC Ref. No.: 2021.196-T). All participants will be required to provide written informed consent. Results of the study will be disseminated through publication in peer-reviewed journals and presentation at local or international conferences.

TEARS: a longitudinal investigation of the prevalence, psychological associations and trajectory of poststroke emotionalism

OBJECTIVE

There are few longitudinal studies of poststroke emotionalism (PSE) and our understanding of the psychological associations of PSE is limited, constraining assessment of existing interventions and the development of new therapies. This study aimed to assess the prevalence and course of PSE over the first year poststroke, and its psychological associations.

METHODS

Consenting stroke survivors who were physically and cognitively able to participate were assessed within 2 weeks, 6 and 12 months of stroke to determine PSE point prevalence using a diagnostic, semistructured PSE interview (Testing Emotionalism After Recent Stroke-Diagnostic Interview). At the same assessments, neuropsychological and disability status were determined using Hospital Anxiety and Depression Scale, Abbreviated Mental Test, National Institute of Health Stroke Scale, Barthel Index and Euro-Qol.

RESULTS

Two hundred and seventy seven stroke survivors were recruited between 1 October 2015 and 30 September 2018. Diagnostic data were available at baseline for 228 of 277 cohort participants. Point prevalence for PSE was 27.2% at 2 weeks; estimated prevalence at 6 months adjusted for baseline was 19.9% and at 12 months 22.3%. PSE was associated with symptoms of anxiety and event-related distress.

INTERPRETATION

PSE affects at least one in five stroke patients acutely following their stroke, and continues to affect one in eight longer term. PSE is associated with anxiety and event-related distress but is not simply a manifestation of mood disorder over time. Such psychological correlates may have implications for longer term social rehabilitation.

Evaluation of an online intervention for improving stroke survivors' health-related quality of life: A randomised controlled trial

BACKGROUND

The aim of this trial was to evaluate the effectiveness of an online health behaviour change intervention-Prevent 2nd Stroke (P2S)-at improving health-related quality of life (HRQoL) amongst stroke survivors at 6 months of follow-up.

METHODS AND FINDINGS

A prospective, blinded-endpoint randomised controlled trial, with stroke survivors as the unit of randomisation, was conducted between March 2018 and November 2019. Adult stroke survivors between 6 and 36 months post-stroke with capacity to use the intervention (determined by a score of ≥4 on the Modified Rankin Scale) and who had access and willingness to use the internet were recruited via mail-out invitations from 1 national and 1 regional stroke registry. Participants completed baseline (n = 399) and 6-month follow-up (n = 356; 89%) outcome assessments via computer-assisted telephone interviewing (CATI). At baseline the sample had an average age of 66 years (SD 12), and 65% were male. Randomisation occurred at the end of the baseline survey; CATI assessors and independent statisticians were blind to group allocation. The intervention group received remote access for a 12-week period to the online-only P2S program (n = 199; n = 28 lost at follow-up). The control group were emailed and posted a list of internet addresses of generic health websites (n = 200; n = 15 lost at follow-up). The primary outcome was HRQoL as measured by the EuroQol Visual Analogue Scale (EQ-VAS; self-rated global health); the outcome was assessed for differences between treatment groups at follow-up, adjusting for baseline measures. Secondary outcomes were HRQoL as measured by the EQ-5D (descriptive health state), diet quality, physical activity, alcohol consumption, smoking status, mood, physical functioning, and independent living. All outcomes included the variable 'stroke event (stroke/transient ischaemic attack/other)' as a covariate, and analysis was intention-to-treat. At 6 months, median EQ-VAS HRQoL score was significantly higher in the intervention group than the control group (85 vs 80, difference 5, 95% CI 0.79-9.21, p = 0.020). The results were robust to the assumption the data were missing at random; however, the results were not robust to the assumption that the difference in HRQoL between those with complete versus missing data was at least 3 points. Significantly higher proportions of people in the intervention group reported no problems with personal care (OR 2.17, 95% CI 1.05-4.48, p = 0.0359) and usual activities (OR 1.66, 95% CI 1.06-2.60, p = 0.0256) than in the control group. There were no significant differences between groups on all other secondary outcomes. The main limitation of the study is that the sample comprises mostly 'well' stroke survivors with limited to no disability.

CONCLUSIONS

The P2S online healthy lifestyle program improved stroke survivors' self-reported global ratings of HRQoL (as measured by EQ-VAS) at 6-month follow-up. Online platforms represent a promising tool to engage and support some stroke survivors.

Acceptance and commitment therapy for individuals with depressive and anxiety symptoms following acquired brain injury: A non-concurrent multiple baseline design across four cases

Patients with acquired brain injury (ABI) often experience symptoms of anxiety and depression. Until now, evidence-based treatment is scarce. This study aimed to investigate the effectiveness of Acceptance and Commitment Therapy (ACT) for patients with ABI. To evaluate the effect of ACT for people with ABI, a non-concurrent multiple baseline design across four cases was used. Participants were randomly assigned to a baseline period, followed by treatment and then follow-up phases. Anxiety and depressive symptoms were repeatedly measured. During six measurement moments over a year, participants filled in questionnaires measuring anxiety, depression, stress, participation, quality of life, and ACT-related processes. Randomization tests and NAP scores were used to calculate the level of change across phases. Clinically significant change was defined with the Reliable Change Index. Three out of four participants showed medium to large decreases in anxiety and depressive symptoms (NAP = 0.85 till 0.99). Furthermore, participants showed improvements regarding stress, cognitive fusion, and quality of life. There were no improvements regarding psychological flexibility, value-driven behaviour, or social participation. This study shows that ACT is possibly an effective treatment option for people experiencing ABI-related anxiety and depression symptoms. Replication with single case or large scale group studies is needed to confirm these findings.

Predictors and correlates of emotionalism across acquired and progressive neurological conditions: A systematic review

Emotionalism can develop following a range of neurological disorders; however the aetiology of emotionalism is still unclear. To identify anatomical, neuropsychological and psychological predictors and correlates of emotionalism across neurological disorders: stroke, Parkinson's disease, multiple sclerosis, traumatic brain injury, Alzheimer's disease, vascular dementia and amyotrophic lateral sclerosis. To explore if these predictors and correlates of emotionalism differ across neurological disorders. A comprehensive systematic search was completed of four databases: MEDLINE, CINAHL Complete, PsycINFO and EMBASE. Methodological quality was assessed using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and each study was graded according to the level of evidence using the Scottish Intercollegiate Guidelines Network. Fifty papers (participants N = 1922) were included. 25 studies were rated as "Fair," 21 "Good" and 4 "Poor." The review identified predictors and correlates found in several neurological disorder such as bulbar networks, serotonergic pathways, genetics and female gender. Multiple studies across diseases (stroke, MS, ALS) indicate emotionalism is associated with cognitive impairment, especially frontal deficits. Due to the disproportionate number of studies identified across neurological disorders, it is difficult to draw definitive answers. Further research is required across neurological disorders to explore similarities and differences in anatomical, neuropsychological and psychological predictors and correlates.

Stroke and Risk of Mental Disorders Compared With Matched General Population and Myocardial Infarction Comparators

BACKGROUND

Accurate estimates of risks of poststroke outcomes from large population-based studies can provide a basis for public health policy decisions. We examined the absolute and relative risks of a spectrum of incident mental disorders following ischemic stroke and intracerebral hemorrhage.

METHODS

During 2004 to 2018, we used Danish registries to identify patients (≥18 years and with no hospital history of mental disorders), with a first-time ischemic stroke (n=76767) or intracerebral hemorrhage (n=9344), as well as age-,sex-, and calendar year-matched general population (n=464 840) and myocardial infarction (n=92 968) comparators. We computed risk differences, considering death a competing event, and hazard ratios adjusted for income, occupation, education, and history of cardiovascular and noncardiovascular comorbidity.

RESULTS

Compared with the general population, following ischemic stroke, the 1-year risk difference was 7.3% (95% CI, 7.0-7.5) for mood disorders (driven by depression), 1.4% (95% CI, 1.3-1.5) for organic brain disorders (driven by dementia and delirium), 0.8% (95% CI, 0.7-0.8) for substance abuse disorders (driven by alcohol and tobacco abuse), and 0.5% (95% CI, 0.4-0.5) for neurotic disorders (driven by anxiety and stress disorders). For suicide, risk differences were near null. Hazard ratios were particularly elevated in the first year of follow-up, ranging from a 2- to a 4-fold increased hazard, decreasing thereafter. Compared with myocardial infarction patients, the 1-year risk difference was 4.9% (95% CI, 4.6 to 5.3) for mood disorders, 1.0% (95% CI, 0.8 to 1.1) for organic brain disorders, 0.1% (95% CI, 0.0 to 0.2) for substance abuse disorders, but -0.2% (95% CI, -0.2 to -0.1) for neurotic disorders. Hazard ratios during the first year of follow-up were elevated 1.1- to 1.8-fold for mood, organic brain, and neurotic disorders, while decreased 0.8-fold for neurotic disorders.

CONCLUSIONS

The considerably greater risks of mental disorders following a stroke, particularly mood disorders, underline the importance of mental health evaluation after stroke.

Spectrum of neuropsychiatric symptoms in chronic post-stroke aphasia

BACKGROUND

Neuropsychiatric symptoms (NPS) have been insufficiently examined in persons with aphasia (PWA) because most previous studies exclude participants with language and communication disorders.

AIM

To report a two-part study consisting of a literature review and an observational study on NPS in post-stroke aphasia.

METHODS

Study 1 reviewed articles obtained from PubMed, PsycINFO, Google Scholar and Cochrane databases after cross-referencing key words of post-stroke aphasia to NPS and disorders. Study 2 examined language deficits and activities of daily living in 20 PWA (median age: 58, range: 28-65 years; 13 men) with the Western Aphasia Battery-Revised and the Barthel Index, respectively. Informants of these 20 PWA were proxy-evaluated with the Neuropsychiatric Inventory and domain-specific scales, including the Stroke Aphasia Depression Questionnaire-10 item version and the Starkstein Apathy Scale. In addition, an adapted version of the Hospital Anxiety and Depression Scale was directly administered to the PWA themselves. This observational study is based on the baseline assessment of an intervention clinical trial (EudraCT: 2017-002858-36; ClinicalTrials.gov identifier: NCT04134416).

RESULTS

The literature review revealed a broad spectrum of NPS in PWA, including depression, anxiety, apathy, agitation/aggression, eating and sleep disorders, psychosis, and hypomania/mania. These findings alert to the need for improving assessment and treatment approaches of NPS taking into consideration their frequent occurrence in PWA. Study 2 showed that the 20 participants had mild- to-moderate aphasia severity and were functionally independent. A wide range of comorbid NPS was found in the post-stroke aphasic population (median number of NPS: 5, range: 1-8). The majority of PWA (75%) had depressive symptoms, followed by agitation/aggression (70%), irritability (70%), anxiety (65%) and appetite/eating symptoms (65%). Half of them also presented symptoms of apathy, whereas euphoria and psychotic symptoms were rare (5%). Domain-specific scales revealed that 45% of participants had apathy and 30% were diagnosed with depression and anxiety.

CONCLUSION

Concurrent NPS are frequent in the chronic period of post-stroke aphasia. Therefore, further research on reliable and valid assessment tools and treatment for this aphasic population is strongly warranted.

Intra- and interpersonal effects of coping style and self-efficacy on anxiety, depression and life satisfaction in patient-partner couples after stroke

Many stroke patients and partners suffer from anxiety, depression, and low life satisfaction. Psychological factors such as coping style and self-efficacy can be protective factors within individuals. The close relationship between stroke patients and partners suggests that there may be interdependence in psychological functioning. The aim of this study was to examine intra- and interpersonal effects of coping style and self-efficacy on anxiety, depression, and life satisfaction in patient-partners couples. In this prospective cohort study, pro-active coping (UPCC), general self-efficacy (GSES), anxiety (HADS-A), depression (HADS-D), and life satisfaction (1-6 scale) were assessed in 215 couples at 2 and 12 months post-stroke. Effects within couples were assessed using structural equation modelling. Several intra- and interpersonal effects of coping style and self-efficacy at 2 months post-stroke were related to emotional health at 12 months post-stroke. Most effects were intrapersonal effects. The interpersonal effects were small but showed that pro-active coping by the patient was associated with lower anxiety of the partner. Higher self-efficacy of the partner was associated with lower depression scores and higher life satisfaction of the patient. This study underscores the importance of a dyadic approach to post-stroke functioning. It supports a family-based approach for treating post-stroke emotional problems.
