Depression, Anxiety, and Suicide After Stroke: A Narrative Review of the Best Available Evidence

Investigating the shared genetic architecture between anxiety and stroke

BACKGROUND

An epidemiological association between anxiety and stroke is well-established; however, the role of shared genetic factors remain unclear. This study aimed to investigate the shared genetic architecture between anxiety and stroke.

METHODS

Using public genome-wide association study (GWAS) summary statistics of anxiety and stroke, we performed linkage disequilibrium score regression and super genetic covariance analyzer for global and local genetic correlation studies. Risk single nucleotide polymorphisms (SNPs) were identified through genome-wide association meta-analysis, multi-trait analysis of GWAS and PLINK, followed by functional mapping and annotation. Additionally, we conducted transcriptome-wide association studies to explore the relationship between genes and associated disease risk.

RESULTS

Our analysis revealed a significant genome-wide genetic correlation between anxiety and stroke. We also identified one previously unreported significant SNP (rs62099231), one risk loci, as well as identified three shared risk genes for anxiety and stroke (WDR6, CCDC71, NCKIPSD).

CONCLUSION

Our study demonstrated a shared genetic structure between anxiety and stroke, enhancing our understanding of their pathogenesis and highlighting potential therapeutic targets.

Who am I now? A scoping review on identity changes in post-stroke aphasia

PURPOSE

Provide an overview of existing knowledge on the concept of identity and identity changes and formation of people with language disorders of aphasia. To date, there has been limited exploration of identity changes of people with aphasia as communication difficulties have been perceived as a barrier to participation by researchers.

METHOD

A scoping review was performed utilizing Arksey and O'Malley's methodological framework. The databases PubMed, PsycINFO, CINAHL, and Cochrane Library were searched, and both descriptive and thematic analysis were conducted.

RESULTS

The search yielded 492 records, of which 20 studies were included. The analysis revealed various theories and definitions of identity. There was limited uniformity in defining identity in the publications. A recurrent theme was, that identity is a social construct and storytelling is the vehicle through which it is navigated. Language and communication are essential in this process.

CONCLUSIONS

The model of Narrative Identity might be useful to clarify identity and its dynamic nature, since it integrates various theories of identity referred to in the publications. Different aspects of identity should be considered in future research to add to existing knowledge of identity changes and formation in people with aphasia and to tailor future interventions if necessary.

Exploring Discharge Preparedness of Patients With Stroke: A Qualitative Descriptive Study

Aim: This study aimed to explore the experiences and perceptions of patients in a rehabilitation center who had experienced a stroke, regarding their concerns about discharge and life after stroke. Methods: A qualitative descriptive design was used and unstructured interviews were conducted with 100 patients with stroke. Reflexive thematic analysis was employed to identify recurring patterns and themes in the data, ensuring an in-depth understanding of the participants' experiences. Results: Three themes were generated from the analysis: (a) general post-hospitalization concerns, (b) concerns regarding the ability to handle activities of daily living, and (c) post-discharge aspirations and goals. Conclusions: This study sheds light on the diverse perspectives of patients with stroke regarding discharge from rehabilitation centers. A person-centered approach for patients with stroke is an important step for coordinating discharge planning. Developing a personalized care plan for meeting patients' needs is critical to address fundamental care issues.

Carotid revascularization improves cognition in patients with carotid stenosis

Patients with atherosclerosis in the carotid arteries are at risk of ischemic stroke and cognitive decline due to emboli and chronic hypoperfusion of brain tissue. Revascularization procedures improve cerebral hemodynamics, which has some effect on cognitive function. Some authors suggest that the presence of stenosis in the carotid arteries is an independent factor influencing cognitive decline. The aim of this study was to investigate the relationship between the degree of stenosis of a stented carotid artery and attentional performance in individuals with carotid atherosclerosis. A prospective longitudinal study was conducted at a single center involving patients during cardiology hospitalization (T-1) and 1 year after hospital admission (T-2) for invasive treatment of carotid stenosis. The attention D2 test by R. Brickenkamp was used. The study showed that a critical degree of internal carotid artery stenosis is associated with poorer attentional performance in individuals undergoing carotid artery stenting. However, the ability to concentrate improved one year after the procedure in all groups of patients who underwent carotid artery stenting, regardless of the degree of internal carotid artery stenosis. It was also found that the side of the vasoconstriction (right/left) in patients with atherosclerosis in the carotid arteries has no influence on cognitive functions in relation to attention.

Trial-based economic evaluation of the BrainACT study: acceptance and commitment therapy for anxiety and/or depressive symptoms after acquired brain injury

INTRODUCTION

Following acquired brain injury (ABI), individuals often experience anxiety and/or depressive symptoms. BrainACT is an adapted form of Acceptance and Commitment Therapy (ACT) tailored to this target group. The current study is a trial-based health-economic evaluation comparing BrainACT to a psychoeducation and relaxation control treatment.

METHODS

An economic evaluation from a societal perspective was conducted in the Netherlands alongside a multicenter randomized controlled two-armed parallel trial including 72 participants. A cost-utility and cost-effectiveness analysis was conducted where incremental costs, quality-adjusted life-years (QALYs), and anxiety/depression (Hospital Anxiety and Depression Scale (HADS) score) were collected and presented over a 1-year follow-up period. Bootstrapping, scenario, and subgroup analyses were performed to test the robustness of the results.

RESULTS

The BrainACT arm reported non-significant lower total costs (incremental difference of €-4,881; bootstrap interval €-12,139 to €2,330) combined with significantly decreased anxiety/depression (HADS) (3.2; bootstrap intervals 0.7-5.7). However, the total QALYs were non-significantly lower (-0.008; bootstrap interval -0.060 to 0.042) for BrainACT. The probability of the intervention being cost-effective was 86 percent at a willingness-to-accept threshold of €50,000/QALY. The scenario and subgroup analyses confirmed the robustness of the results.

CONCLUSION

BrainACT may be a more cost-effective alternative to a psychoeducation and relaxation intervention for anxiety and/or depressive symptoms following ABI. Despite limitations, BrainACT appears to be a promising addition to treatment options in the Netherlands. Further research is needed to validate these findings, and consideration should be given to implementing BrainACT in Dutch clinical settings with ongoing monitoring.

Supporting Long-Term Meaningful Outcomes in Stroke Rehabilitation

PURPOSE OF REVIEW

Rehabilitation is the mainstay of recovery after stroke, but key recommendations focused on delivering 'as much therapy as possible' and stroke survivor outcome measures have remained relatively unchanged for decades. Traditional therapy approaches focus on maximum improvement of physical impairments while a stroke survivor is in hospital to ensure that community discharge can be deemed 'safe'. This narrow approach sidelines the outcomes that are meaningful to the stroke survivor in the long term and the challenges they may face within their social context. In this article, we highlight the importance of the whole-person approach and review recent research introducing novel considerations to optimise outcomes after stroke.

RECENT FINDINGS

Psychosocial well-being is a major component of health but is poorly acknowledged and managed for stroke survivors. Evidence supports the use of self-management interventions, peer befriending, and culturally - responsive methods, including deep engagement with Indigenous and cultural knowledge. Cultural safety and involvement of a stroke survivor's important personal connections are also vital for achieving truly person-centred care and equity in rehabilitation outcomes. Outcomes in rehabilitation will be optimised if we shift our mindsets from a sole focus on improving physical impairments to a broader scope of delivering whole-person care.

Three Pillars of Recovery After Aneurysmal Subarachnoid Hemorrhage: A Narrative Review

Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating neurologic disease with high mortality and disability. There have been global improvements in survival, which has contributed to the prevalence of patients living with long-term sequelae related to this disease. The focus of active research has traditionally centered on acute treatment to reduce mortality, but now there is a great need to study the course of short- and long-term recovery in these patients. In this narrative review, we aim to describe the core pillars in the preservation of cerebral function, prevention of complications, the recent literature studying neuroplasticity, and future directions for research to enhance recovery outcomes following aSAH.

Associations Between Elevated Rates of Depression, Anxiety, and PTSD Among ICU Survivors and Increased Mortality and Readmissions

PURPOSE

Intensive care unit (ICU) mortality has decreased, highlighting improved patient outcomes. However, other critical factors affect post-ICU survival, including lasting physical, cognitive, and psychological challenges termed postintensive care syndrome (PICS), encompassing depression, anxiety, and posttraumatic stress disorder (PTSD). The prevalence of these conditions among ICU survivors is high and potentially linked to ICU treatment. This study aims to understand these factors using Taiwan's National Health Insurance Research Database (NHIRD), exploring their impact on mortality and readmission rates post-ICU discharge.

METHODS

The National Health Insurance (NHI) program in Taiwan, implemented in 1995, provides healthcare for nearly all residents. Its research arm, NHIRD, contains comprehensive medical data for nationwide studies. This research focuses on ICU patients with specific conditions from 2010 to 2018, using ICD codes for diagnosis. Statistical analyses include Cox proportional hazard models and logistic regression, aiming to assess the incidence and risks of anxiety/depression/PTSD.

RESULTS

ICU patients showed a higher risk of anxiety/depression/PTSD compared to non-ICU patients (adjusted HR = 1.17), with similar trends for anxiety and depression. Females, younger patients, those with higher CCI scores, on mechanical ventilators, and more extended hospital stays had increased odds of anxiety/depression/PTSD. ICU patients with anxiety/depression/PTSD faced increased risks of death and re-admission, especially among older males with comorbidities.

CONCLUSION

This study discovered higher anxiety and depression rates post-ICU compared to general ward patients, particularly among younger individuals, females, and those with longer hospital stays. Factors such as higher comorbidity scores and mechanical ventilation use were linked to lower odds. Addressing mental health postdischarge is crucial, especially for at-risk groups.

Relationship between physical activity and depressive symptoms in stroke survivors: a cross-sectional study of 1,140 individuals

OBJECTIVES

To investigate the relationship between physical activity and depressive symptoms in stroke survivors.

DESIGN

A cross-sectional study utilizing National Health and Nutrition Examination Survey (NHANES) 2007-2018 data, employing propensity score matching to control for confounders.

PATIENTS

1,140 stroke survivors from NHANES, assessing depressive symptoms through the Patient Health Questionnaire-9 (PHQ-9) conducted via family interview or a mobile examination centre examination.

METHODS

PA was surveyed concurrently with the PHQ-9, categorized into vigorous, moderate, and moderate-to-vigorous intensities. Propensity score matching was used to match participants based on their activity levels, and the relationship between physical activity and depressive symptoms was analysed by logistic regression.

RESULTS

Among all the subjects, 225 individuals had significant depressive symptoms. If vigorous-intensity PA duration is longer than 75 min (odds ratio [OR] = 0.41, 95% CI 0.21-0.75) or longer than 150 min (OR = 0.42, 95% CI 0.19-0.85), and moderate-intensity physical activity duration is longer than 150 min (OR = 0.59, 95% CI 0.38-0.90) or between 150 and 300 min (OR = 0.36, 95% CI 0.15-0.77), and moderate-to-vigorous PA duration is greater than 150 min (OR = 0.61, 95% CI 0.40-0.91) or exceeding 300 min (OR = 0.50, 95% CI 0.31-0.78), this might be associated with lower depressive symptoms.

CONCLUSION

Regular physical activity, particularly of moderate or higher intensity, is associated with milder depressive symptoms in stroke survivors, suggesting the potential for non-pharmacological intervention.

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.

Predictors of affective disturbances and cognitive impairment following small spontaneous supratentorial intracerebral hemorrhage

BACKGROUND AND PURPOSE

Affective disturbances and cognitive impairment are common sequelae of intracerebral hemorrhage (ICH), yet predictive models for these outcomes remain limited, especially for spontaneous supratentorial ICH with small hematomas (<30 mL). The aim of this study was to investigate predictors of affective disturbances and cognitive impairment following small spontaneous supratentorial intracerebral hemorrhage.

METHODS

We retrospectively analyzed 1692 patients with spontaneous supratentorial ICH between January 2018 and December 2020 at the First Affiliated Hospital of Harbin Medical University. Of these, 1563 patients completed a median follow-up of 3.5 years. Cognitive function was evaluated using the modified Telephone Interview for Cognitive Status, and affective disturbances using the Hamilton Depression Scale and the Hamilton Anxiety Scale. Restricted cubic spline analyses were employed to examine the relationships between predictors and outcomes.

RESULTS

In this cohort, 58.5% had cognitive impairment, 52.8% reported depressive symptoms, and 39.4% exhibited anxiety symptoms. Logistic regression models using Boruta's algorithm demonstrated strong predictive capacity, with areas under the curve of 0.82 for cognitive impairment, 0.78 for depressive symptoms, and 0.73 for anxiety symptoms. Hematoma volume was significantly linked to depressive symptoms (odds ratio [OR] 1.56, 95% confidence interval [CI] 1.38-1.76) and inversely to cognitive impairment (OR 0.67, 95% CI 0.59-0.77). Uric acid levels displayed a nonlinear relationship with cognitive impairment (OR 0.70, 95% CI 0.61-0.81). Hospitalization days significantly raised the risk of both depressive (OR 1.16, 95% CI 1.03-1.30) and anxiety symptoms (OR 1.17, 95% CI 1.04-1.31).

CONCLUSIONS

The logistic regression model, enhanced by Boruta's algorithm, provides a valuable tool for predicting affective disturbances and cognitive impairment after ICH. It facilitates early identification and improves risk assessment for these neuropsychiatric outcomes in patients with small hematomas.

How tube feeding modes influence anxiety in patients with dysphagia after ischemic stroke: A propensity score-matched, longitudinal study

BACKGROUND

Although tube feeding modes have been shown to influence psychological status, the specific mechanism of action and differences between intermittent oro-esophageal tube feeding (IOE) and nasogastric tube feeding (NGT) have yet to be uncovered. This study explored the effect of IOE versus NGT on anxiety in patients with dysphagia after ischemic stroke.

METHODS

This longitudinal observational study included patients with dysphagia after ischemic stroke who were treated in the Department of Rehabilitation Medicine between February 2022 and June 2024. Questionnaires, scales, and medical records were used to collect data regarding anxiety symptoms, basic information, treatment details, and self-perception on the 1st and 10th day of hospitalization. Propensity Score Matching (PSM) was used to balance potential confounding factors and analyze the association between IOE versus NGT and anxiety symptoms. Path analysis was conducted to explore the specific mechanisms of action.

RESULTS

Totally, 2459 participants (55.51% IOE users) were recruited. The IOE users had significantly lower moderate-to-severe anxiety rates than the NGT users (25.88% and 44.42%, p < 0.001). PSM analysis revealed an 8.56% difference in moderate-to-severe anxiety rates between IOE and NGT users. Self-perception of comfort, reflux, dietary schedule, social activity, self-esteem, and daily exercise showed significance as intermediate variables between tube feeding modes and anxiety symptoms in path analysis (all p < 0.001).

CONCLUSIONS

Compared to NGT, IOE can alleviate anxiety symptoms in patients with dysphagia after ischemic stroke who were treated in the Department of Rehabilitation Medicine. The relationship between tube feeding modes and anxiety symptoms was mediated by the self-perception of comfort, reflux, dietary schedule, social activity, self-esteem, and daily exercise.

Depression and anxiety at 1- and 12-months post ischemic stroke: methods for examining individual change over time

Background Depression is commonly studied post stroke, while anxiety is less studied. This study presents prevalence of depression and anxiety at 1- and 12-months post ischemic stroke alongside three methods for examining within-subjects change over time. Methods Participants were ischemic stroke patients of the Auckland Regional Community Stroke Study (ARCOS-V) with Hospital Anxiety and Depression Scale data at 1- (n =343) and 12-months (n =307). Change over time was examined using within-subjects repeated measures ANOVA, calculation of the Reliable Change Index, and a Sankey diagram of those meeting cut-off scores (>7) for caseness over time. Results Using repeated measures ANOVA, depression scores didn't change significantly over time, while anxiety symptoms decreased significantly. When reliable change was calculated, 4.2% of individuals had reliable decreases in anxiety symptoms, while 5.7% had reliable decreases in depression symptoms. Those who had a reliable decrease in one tended to have a reliable decrease in the other. In the Sankey, the proportion of those meeting the cut-off score for anxiety did not change over time (12.8 and 12.7% at 1- and 12-months), while those meeting the cut-off for depression increased slightly (3.7-4.5%) and those meeting cut-offs for both decreased from 10.4 to 8.1%. Conclusion The three methods produced very different findings. Use of cut-off scores is common but has limitations. Calculation of clinically reliable change is recommended. Further work is needed to ensure depression and anxiety are monitored over time post-stroke, and both should be the subject of intervention efforts in both acute and late stages post-stroke.

Delivery of Neuropsychological Interventions for Adult and Older Adult Clinical Populations: An Australian Expert Working Group Clinical Guidance Paper

Delivery of neuropsychological interventions addressing the cognitive, psychological, and behavioural consequences of brain conditions is increasingly recognised as an important, if not essential, skill set for clinical neuropsychologists. It has the potential to add substantial value and impact to our role across clinical settings. However, there are numerous approaches to neuropsychological intervention, requiring different sets of skills, and with varying levels of supporting evidence across different diagnostic groups. This clinical guidance paper provides an overview of considerations and recommendations to help guide selection, delivery, and implementation of neuropsychological interventions for adults and older adults. We aimed to provide a useful source of information and guidance for clinicians, health service managers, policy-makers, educators, and researchers regarding the value and impact of such interventions. Considerations and recommendations were developed by an expert working group of neuropsychologists in Australia, based on relevant evidence and consensus opinion in consultation with members of a national clinical neuropsychology body. While the considerations and recommendations sit within the Australian context, many have international relevance. We include (i) principles important for neuropsychological intervention delivery (e.g. being based on biopsychosocial case formulation and person-centred goals); (ii) a description of clinical competencies important for effective intervention delivery; (iii) a summary of relevant evidence in three key cohorts: acquired brain injury, psychiatric disorders, and older adults, focusing on interventions with sound evidence for improving activity and participation outcomes; (iv) an overview of considerations for sustainable implementation of neuropsychological interventions as 'core business'; and finally, (v) a call to action.

Clinical Effectiveness of Multimodal Exercise Combined With Supportive Music and Imagery in the Management of Poststroke Mood Disorders

ABSTRACT

BACKGROUND: The objective of this study is to investigate the clinical effectiveness of the combination of multimodal exercise (MME) with supportive music and imagery in the management of poststroke mood disorders (PSMD). METHODS: A total of 200 PSMD patients treated in the neurology department of a tertiary hospital in Jiangsu Province were enrolled. They were assigned to either a control group or the observation group using a random number table at a 1:1 ratio, with 100 patients in each group. The control group received conventional nursing care, and the observation group received both MME and music and imagery in addition to the conventional nursing interventions. The scores of the 10-item Kessler Psychological Distress Scale (K10), Hospital Anxiety and Depression Scale (HADS), and Well-being Index Scale (WBIS) were recorded before and 3, 6, and 9 months after the interventions and compared between the 2 groups. RESULTS: Changes in K10, HADS, and WBIS scores significantly differed between the 2 groups after interventions (all P < .05) and among different time points (all P < .05). There were interactions between the time points of the K10, HADS, and WBIS assessments and the intervention methods in both groups ( P < .05). The improvements in anxiety or depression and psychological distress in the observation group were significantly superior to those in the control group. CONCLUSION: MME combined with music and imagery can effectively improve anxiety and depression, reduce symptoms of psychological distress, and improve well-being in PSMD patients.

Exploring Music-Based Interventions for Executive Functioning and Emotional Well-Being in Stroke Rehabilitation: A Scoping Review

PURPOSE

Stroke is one of the leading causes of disability with life-long implications requiring assessment and treatment of several functional domains. This review identifies the results from research into music-based interventions (MBIs), including music therapy (MT), for executive functions (EFs) and emotional well-being (EWB) in adults with stroke and highlights opportunities for clinical practice and future research.

METHODS

APA PsycInfo (EBSCOhost), and CINAHL (EBSCOhost) were searched, in addition to grey literature.

RESULTS

A total of 49 studies were included and encompassed experimental, analytic, and descriptive observational studies, and case reports, involving a total of 1663 participants. In total, 32 studies included MT interventions, and 17 were MBIs. EFs were an outcome in 20.41%, and EWB in 61.22% of studies, for which active interventions were the most utilized. Overall, 73.47% of the studies reported positive results.

CONCLUSIONS

This scoping review indicates that music interventions can be beneficial for the improvement of different aspects of EFs and EWB at different stages of stroke recovery. Further research may benefit clinical practice by including standardized protocols, outcome and self-reported measures, and brain imaging data to determine the effects of interventions and support evidence-based decisions for treatment policies for stroke survivors.

Link between post-stroke psychopathology and scope-of-action awareness

Background

Epidemiological research has failed to confirm laterality of lesion site as a neurobiological source of post-stroke psychopathology. However, acquired communication disorders have proved to be a key risk factor for depression, apart from established parameters such as pre-stroke psychopathology and physical immobility.

Objectives

The present work examines a new predictor of post-stroke psychopathology: psychological flexibility. This concept describes an accepting attitude toward irreversible loss following stroke while using remaining agency.

Design

Overall, 70 individuals engaged in a cross-sectional study conducted in the subacute stage after an ischemic or hemorrhagic event, a period with elevated prevalence of mental-health problems (2 weeks to 6 months after stroke).

Methods

Outcomes included standardized self-report and clinician-rated measures of depression, anxiety disorders, and general psychopathology (Beck Depression Inventory; Hospital Anxiety and Depression Scale; ICD-10 Symptom Rating; Hamilton Depression Rating Scale) alongside lack of psychological flexibility (Acceptance and Action Questionnaire II). The study design controlled for pre-stroke psychopathology and physical immobility (Barthel Index).

Results

Partial correlation analyses revealed a significant medium-to-large association between the entire set of clinical outcomes and lack of psychological flexibility (r ⩽ 0.62, p < 0.001). In moderator analyses, the magnitude of this association did not vary significantly with diagnosis of acquired communication disorders (i.e., aphasia, apraxia of speech or dysarthria; separately or combined).

Conclusion

The current results demonstrate a substantial link between post-stroke psychopathology and psychological flexibility. This finding opens new avenues for research on depression and other mental-health problems in stroke survivors with and without acquired communication disorders.

Safety and efficacy of fluoxetine in post-stroke anxiety-A pilot prospective randomized open blinded endpoint (PROBE) study

OBJECTIVE

The prevalence of post-stroke anxiety (PSA) is reported to be 20%-25%. There is insufficient evidence on the efficacy of antidepressants for treating anxiety in such patients. This Prospective Randomized Open Blinded Endpoint (PROBE) study was designed to assess the safety and efficacy of fluoxetine in PSA.

METHODS

In this single-center pilot study conducted in India, post-stroke patients (between 1 to 6 months) were randomized to fluoxetine (intervention group: 20 mg/day for 12 weeks) or standard medical care (control group). The primary outcome was improvement in the Hamilton Anxiety Rating Scale (HAM-A) at 12 weeks. The secondary outcomes were anxiety remission (>50% improvement in HAM-A), modified Rankin Scale (mRS), Barthel Index (BI), quality of life (SF-36), and Hamilton Depression Rating Scale (HAM-D). A linear regression analysis was done for determinants of HAM-A to account for baseline differences in the intervention and control groups.

RESULTS

A total of 60 patients were randomized: (30: intervention, 30: control). The overall prevalence of post-stroke anxiety among participants in the study was 50.8%, and 31.5% experienced both anxiety and depression. The average HAM-A score at baseline was 11, and average follow-up score at study conclusion was 4. There was similar improvement in the HAM-A score at 12 weeks post-randomization in the intervention and control groups [fluoxetine: -8.0 (95% CI = -11.0 to -4.0); control: -7.0 (95% CI = -9.5 to -4.0); P = 0.91]. Likewise, there was no significant difference between intervention and control groups at 12 weeks post-randomization on the mRS, BI, SF-36, or HAM-D. There were no serious adverse events in either group during the study.

CONCLUSION

Fluoxetine and standard medical care had comparable improvement in HAM-A in post-stroke patients with mild anxiety at 12 weeks. Further study of the pharmacological treatment of post-stroke patients with more severe anxiety is needed.

Relationship of subjective and objective cognition with post-stroke mood differs between early and long-term stroke

Objective: Depression and anxiety affects approximately 1 in 3 stroke survivors. Performance on standardized objective cognitive tests and self-reported subjective cognitive symptoms are associated with concurrent depression and anxiety, but longitudinal data on whether and how objective and subjective cognition relate to emotional outcomes are lacking. Method: N = 99 stroke survivors (M age = 68.9, SD = 13.1; Median NIH Stroke Severity = 5) completed measures of depression and anxiety (Hospital Anxiety and Depression Scale; HADS), objective cognition (Oxford Cognitive Screen) and subjective cognitive symptoms (Cognitive Failures Questionnaire) at 6-months, 4.5, and 5.5 years post-stroke. The contribution of objective and subjective cognition to depression and anxiety was determined via mixed-effects models. Results: We found no evidence that age, stroke severity, years of education, and participant sex related to changes in HADS-Depression or HADS-Anxiety scores (Marginal R2=0.03 and 0.05, respectively). Objective cognitive impairments at 6-months and increases in subjective cognitive symptoms at 5.5 years significantly related to increased HADS-Depression scores (Marginal R2=0.22). Only increases in subjective cognitive symptoms at 5.5 years significantly related to increased HADS-Anxiety scores (Marginal R2=0.20). When conducting models in reverse, HADS-Depression and HADS-Anxiety scores did not reciprocally explain changes in subjective cognitive symptoms. Conclusions: Objective cognitive abilities are more strongly associated with depression at 6-months post-stroke, while subjective cognitive symptoms are more relevant to both long-term post-stroke depression and anxiety. There may be a unique unidirectional influence of subjective cognitive symptoms to post-stroke depression and anxiety.

Post-stroke emotionalism: Diagnosis, pathophysiology, and treatment

BACKGROUND

Post-stroke emotionalism affects one in five stroke sufferers 6 months after their stroke, but despite its frequency remains a poorly understood stroke symptom. The literature is limited, especially compared to other frequently observed neurological conditions such as aphasia and visual neglect.

AIM AND METHODS

This narrative review presents a summary of the post-stroke emotionalism literature, to inform clinical practice and future research. We cover discussion of definitions, prevalence, neurobiology, predisposing and precipitating factors, and treatment.

RESULTS

Increasing evidence suggests that damage to specific areas functionally linked to emotion expression or regulation processes, disruption to structural pathways and those related to serotonin production and modulation individually or in concert give rise to emotionalism-type presentations. A range of emotionalism measurement tools have been used in research contexts making between study comparisons difficult. Testing for Emotionalism after Recent Stroke-Questionnaire (TEARS-Q) has recently been developed to allow standardized assessment. Treatment options are limited, and there have been few adequately powered treatment trials. Antidepressants may reduce severity, but more trial data are required. There have been no randomized-controlled trials of non-pharmacological interventions.

CONCLUSIONS

More research is needed to improve recognition and treatment of this common and disabling symptom. We conclude with research priorities and recommendations for the field.

Association of baseline plasma fibrinogen levels with cognitive and affective status at 30 and 90 days in individuals with ischemic stroke: A prospective study from Nigeria

BACKGROUND

The influence of fibrinogen as a risk factor in developing poststroke neuropsychological and cognitive problems is underreported. This study aimed to evaluate the relationship between baseline fibrinogen levels and depression, anxiety, and cognition 30- and 90-day after stroke.

METHODS

This prospective study involved 48 patients with first-ever mild-to-moderate ischemic stroke, whose plasma fibrinogen levels were assessed within 24 h of stroke onset. Clinical depression, anxiety, and cognitive impairment were evaluated by the Hospital Anxiety and Depression Scale and Montreal Cognitive Assessment at 30- and 90-day after stroke.

RESULTS

After adjusting for important covariates, the multiple linear regression models showed that baseline plasma fibrinogen was associated with the symptoms of depression, anxiety, and cognitive decline at both 30- and 90-day follow-up (P < 0.05). The receiver operating characteristic curve showed that baseline fibrinogen threshold > 409.0 mg/dl (82.4% sensitivity and 71.0% specificity), >405.0 mg/dl (80.0% sensitivity and 71.4% specificity), and > 400.0 mg/dl (80.6% sensitivity and 76.5% specificity) could respectively predict the presence of depression, anxiety, and cognitive impairment 90 days after stroke.

CONCLUSIONS

High levels of baseline plasma fibrinogen are associated with the onset and severity of symptoms of depression, anxiety, and cognitive decline at 30 and 90 days after stroke. This study shows that fibrinogen may be a viable target for monitoring and intervention in the management of poststroke neuropsychological and cognitive disorders. Future clinical trials are needed to clarify whether defibrinogenation will prevent or reduce the rate and severity of symptoms of depression, anxiety, and cognitive decline among patients with ischemic stroke.

Nature-Based Design in Stroke Rehabilitation Environments: A Scoping Review

OBJECTIVE

To identify, examine, and map the characteristics of knowledge of nature-based design in stroke rehabilitation facilities, examine how research in this field has been conducted and identify gaps in knowledge.

BACKGROUND

Many stroke survivors have wide ranging impacts, resulting in long hospital stays to undertake rehabilitation. The physical environment can influence brain recovery; however, there is limited evidence to support the design of effective rehabilitation environments. Conversely, the health benefits available from connection with nature are well established. A nature-based design approach may have benefits and implications for the physical environment of inpatient stroke rehabilitation facilities; however, it is unclear what evidence exists in this field.

METHOD

This scoping review followed the JBI methodological guidance for the conduct of scoping reviews, with systematic searches of six databases.

RESULTS

Twenty-eight studies were included in the review. Aims and research methods varied widely. Investigations in 19 studies related to gardens and other designed outdoor nature-based environments. Other studies explored natural analogues, nature inside, inside/outside connections, and the natural environment. Findings from the studies were spread across the fields of design, use, exposure to, and engagement in nature-based environments.

CONCLUSION

The characteristics of knowledge underpinning nature-based design in stroke rehabilitation environments are highly diverse, and significant gaps exist in the evidence base. A framework developed during this review for mapping knowledge on the intentions and impacts for spaces and services in this field assisted to identify these gaps and may be applied to other areas of healthcare design research.

Availability and barriers to access post-stroke rehabilitation in Latin America

OBJECTIVES

To describe the availability and barriers to access post-stroke rehabilitation services in Latin America.

MATERIALS AND METHODS

We conducted a multi-national survey in Latin American countries. The survey consisted of three sections: (1) the national state of post-stroke rehabilitation; (2) the local state of post-stroke rehabilitation; and (3) the coverage and financing of post-stroke services. Stroke leaders from the surveyed countries were involved in developing and disseminating the survey.

RESULTS

261 responses were collected from 17 countries. The mean age of respondents was 42.4 ± 10.1 years, and 139 (54.5 %) of the respondents were male. National clinical guidelines for post-stroke rehabilitation were reported by 67 (25.7 %) of the respondents. However, there were discrepancies between respondents within the same country. Stroke units, physiotherapy, occupational therapy, speech therapy, and neuropsychological therapy services were less common in public than private settings. The main barriers for inpatient and outpatient services included limited rehabilitation facilities, coverage, and rehabilitation personnel. The main source of financing for the inpatient and outpatient services was the national health insurance, followed by out-of-pocket payments. Private and out-of-pocket costs were more frequently reported in outpatient services.

CONCLUSIONS

Post-stroke rehabilitation services in Latin American countries are restricted due to a lack of coverage by the public health system and private insurers, human resources, and financial aid. Public settings offer fewer post-stroke rehabilitation services compared to private settings. Developing consensus guidelines, increasing coverage, and using innovative approaches to deliver post-stroke rehabilitation is paramount to increase access without posing a financial burden.

In-person and online mixed method non-randomised studies exploring feasibility and acceptability of HEADS: UP, an adapted Mindfulness-Based Stress Reduction programme for stroke survivors experiencing symptoms of anxiety and depression

BACKGROUND

Depression and anxiety are prevalent after stroke and associated with poor outcomes. We previously co-developed a stroke-specific self-management intervention, HEADS: UP (Helping Ease Anxiety and Depression after Stroke). The two studies reported here aimed to test the feasibility and acceptability of the HEADS: UP course and supporting materials, and research processes ahead of a definitive trial.

METHODS

We recruited community-dwelling stroke survivors (SS) ≥ 3 months post-stroke, with symptoms of mood disorder (Hospital Anxiety and Depression Scale ≥ 8). Participants could 'enrol' a family member/ 'other' to take part with them, if desired. Study 1 tested HEADS: UP delivered in-person, and informed optimisation of research processes and intervention delivery and materials. In a pragmatic response to Covid-related socialising restrictions, HEADS: UP was then adapted for online delivery, tested in Study 2. The primary outcome (both studies) was the feasibility (acceptability, fidelity) of the intervention and of research processes. Quantitative data (including patient-reported outcome measures (PROMs) assessing mood and quality of life) and qualitative data were collected pre-/post-intervention. Descriptive statistics were used to analyse quantitative data; a thematic framework approach was used to analyse qualitative data. Both studies received ethical approval prior to commencement.

RESULTS

Study 1 Feasibility: 13 (59.1%) of 22 potentially eligible stroke survivors consented; aged 66 (median, interquartile range (IQR) 14); male (n = 9; 69%); 28 (IQR 34) months post-stroke. Of these, n = 10 (76.9%) completed PROMS pre-intervention; n = 6 (46.2%) post-intervention. Acceptability: Nine (69.2%) of the 13 participants attended ≥ 4 core intervention sessions. Aspects of screening and data collection were found to be burdensome. Study 2 Feasibility: SS n = 9 (41%) of 22 potentially eligible stroke survivors consented; aged 58 years (median; IQR 12); male (n = 4; 44.4%); 23 (IQR 34) months post-stroke. Of these, n = 5 (55.6%) completed PROMS pre-intervention; n = 5 (55.6%) post-intervention. Acceptability: Five (55.6%) of the 9 participants attended ≥ 4 core sessions. They found online screening and data collection processes straightforward.

Cognitive behavioral stress management effectively facilitates neurologic recovery, alleviates mental distress, and elevates health status in acute ischemic stroke patients

Cognitive behavioral stress management (CBSM) relieves physical and psychological burdens in patients with some central nervous system diseases, while its utility in acute ischemic stroke (AIS) patients is unclear. This study aimed to explore the effect of CBSM on neurologic recovery and psychosomatic health in AIS patients. Totally, 176 naive AIS patients were randomized into routine care (RC) group (n=88) and CBSM group (n=88) to receive a 3-month corresponding intervention. Modified Rankin scale (mRS) scores at the first month after discharge (M1) (P=0.008) and the third month after discharge (M3) (P=0.016) were lower in the CBSM group than in the RC group. The proportion of AIS patients with mRS score >2 at M3 was reduced in CBSM group vs RC group (P=0.045). Hospital anxiety depression scale (HADS)-anxiety score at M3 (P=0.016), HADS-depression score at M3 (P=0.005), and depression rate at M3 (P=0.021) were decreased in the CBSM group vs the RC group. EuroQol-5 dimension scores at M1 (P=0.024) and M3 (P=0.012) were decreased, while EuroQol-visual analogue scale score at M3 (P=0.026) was increased in the CBSM group vs the RC group. By subgroup analyses, CBSM had favorable outcomes in AIS patients with age ≤65 years. CBSM was beneficial to neurologic recovery and distress relief in AIS patients with an education level of middle school or above, and to health status in those with an education level of primary school or uneducated. In conclusion, CBSM benefitted neurologic recovery and psychosomatic health in AIS patients with minor neurological deficits, however, further studies should verify these results with a larger sample size and longer follow-up.

Improving emotion regulation ability after brain injury: A systematic review of targeted interventions

Emotion dysregulation is a common sequela after a brain injury, and it can have serious negative consequences for individuals, families, and the community. A systematic review of the literature was conducted to identify and evaluate interventions designed to improve emotion regulation ability in adults with acquired brain injury. Studies were identified on ProQuest, PsycInfo, ScienceDirect, Scopus, and Web of Science; last searched on 3 August 2023. A review protocol was prospectively registered on PROSPERO (CRD42020218175). Risk of bias was assessed using the Cochrane Risk-of-Bias tool (version 2). Sixteen studies were included in the review comprising one case series, five pilot studies, four pre-post studies, and six RCTs. There was a total of 652 participants across studies. Fourteen of the sixteen studies reported statistically significant improvements in at least one emotional functioning variable. Ten studies reported medium-large effect sizes. Limitations included inconsistency in the measurement, reporting of intervention outcomes and processes. Future directions are discussed.

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.

Investigating the Relationship Between Clinical Characteristics, Mental Health, and Vascular Function in Minor Ischemic Stroke or Transient Ischemic Attack Patients

Background

Over the past decade, there has been extensive research exploring the relationship between vascular health and mental well-being, encompassing aspects such as mood and cognition. However, there is a notable gap in research focusing on the mental and vascular conditions of minor ischemic stroke or transient ischemic attack (TIA) patients, particularly within the Thai population.

Objectives

To investigate the clinical characteristics and mental issues related to vascular functions in patients who have experienced a minor ischemic stroke or TIA. This study, approved by the Buriram Hospital Ethics Committee (IRB: BR0033.102.1/8), adhered to the guidelines of the Helsinki Declaration and obtained informed consent from all participants.

Methods

A prospective cross-sectional study was conducted at Buriram Hospital, a government regional hospital located in Buriram province, Thailand, involving twenty-three participants diagnosed with minor ischemic stroke or TIA. Measurements included clinical characteristics, Hospital Anxiety and Depression Scale-part Anxiety (HADS-A), Hospital Anxiety and Depression Scale-part Depression (HADS-D), mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), flow-mediated dilation (FMD), and brachial-ankle pulse wave velocity (baPWV). Linear regression analysis was employed to investigate the factors associated with vascular function (FMD and baPWV).

Results

The factor related to FMD was HADS-D (β = -0.5, 95% CI -0.33 to -0.04). Factors associated with baPWV included age (β = 0.51, 95% CI 5.05 to 39.50) and the duration of minor ischemic stroke or TIA (β = 0.48, 95% CI 25.41 to 290.99).

Conclusions

FMD shows a connection with depressive symptoms in patients with minor ischemic stroke or TIA. Therefore, it is important to detect and provide appropriate treatment for depressive symptoms in these patients, as it may lead to improvements in vascular function and better cerebrovascular outcomes.

Impact of Baduanjin exercise combined with rational emotive behavior therapy on sleep and mood in patients with poststroke depression: A randomized controlled trial

BACKGROUND

Poststroke depression (PSD) is one of the most common stroke complications. It not only leads to a decline in patients' quality of life but also increases the mortality of patients. In this study, the method of combining Chinese traditional exercise Baduanjin with psychotherapy was used to intervene in patients with PSD and to explore the improvement of sleep, mood, and serum levels of brain-derived neurotrophic factor (BDNF), 5-hydroxytryptamine (5-HT), and interleukin-6 (IL-6) levels in patients with PSD by combined treatment.

METHODS

A total of 100 patients with PSD who met the inclusion criteria were randomly assigned to Baduanjin group (n = 50) or control group (n = 50). The control group received treatment with escitalopram oxalate and rational emotive behavior therapy, while the experimental group received Baduanjin training in addition to the treatment given to the control group. Changes in sleep efficiency, sleep total time, sleep latency, arousal index, Hamilton Anxiety Rating Scale, Hamilton Depression Scale score, serum BDNF, 5-HT, IL-6 levels, and Modified Barthel Index were measured at baseline, 4 weeks and 8 weeks after intervention, and the results were compared between the 2 groups.

RESULTS

Significantly improvements in the sleep efficiency, sleep total time, serum 5-HT, BDNF levels, and Modified Barthel Index score were detected at week 4 in the Baduanjin group than in the control group (P < .05). Additionally, the sleep latency, arousal index, Hamilton Anxiety Rating Scale, Hamilton Depression Scale scores and IL-6 levels in the Baduanjin group were lower than those in the control group (P < .05). After 8 weeks of treatment, the above indexes in the Baduanjin group were further improved compared with the control group (P < .05), and the above indexes of the 2 groups were significantly improved compared with the baseline (P < .001).

CONCLUSION

Baduanjin exercise combined with rational emotive behavior therapy effectively improves the mood and sleep status of patients with PSD; It increases the serum levels of 5-HT and BDNF while reducing the level of serum proinflammatory factor IL-6; additionally, the intervention alleviates the degree of neurological impairment, upgrades the ability of daily living, and improves the quality of life.

Feasibility and user-experience of a virtual environment for social connection and education after stroke: A pilot study

OBJECTIVES

To evaluate the feasibility and usability of stroke survivor participation in an 8-week virtual environment intervention that provides opportunities for social support exchanges, social network interactions, and recovery education.

MATERIALS AND METHODS

A single-group, pre- and post-test measure design was used. Descriptive statistics were used to examine enrollment and retention rates, proportion of questionnaires completed, and virtual environment process data (e.g., number of log-ins) and usability scores. Changes in pre- and post-intervention questionnaire (e.g., usability, social support, depression, anxiety, loneliness, and self-efficacy) scores were explored using Wilcoxon signed-rank tests and paired t-test.

RESULTS

Fifteen (65 %) of the eligible stroke survivors enrolled (60 % white, 27 % black), 12 (80 %) had an ischemic stroke, ages ranged from 33 to 74 years (mean 44 years), and mean months since stroke was 33 ± 23. Retention and questionnaire completion rates were both 93 % (n = 14). Survivors logged into the virtual environment a total of 122 times, logged an average of 49 min/log-in, and 12 (80 %) attended support groups and social activities. Median usability score indicated lower than average usability. Improvement trends in social support, loneliness, and depressive symptoms were found, but significant changes in mean questionnaire scores were not found.

CONCLUSIONS

Overall, the results suggest that using a virtual environment to foster social support exchanges, social network interactions, and recovery education after stroke is feasible. Similar to other chronic disease populations, stroke survivor adoption of a virtual environment likely requires ongoing technical assistance, repetition of instructions, and opportunities for practice to reinforce engagement.

[Comorbid anxiety disorders in patients with neurological pathology: current state of the problem and the role of etifoxine in treatment strategy]

The article presents theses of the resolution of the Interdisciplinary Council of Experts in Psychiatry and Neurology (Moscow, 2024) on the issue of comorbid anxiety disorders (AD) in patients with neurological pathologies. The authors highlight the high prevalence of comorbid ADs and their significant negative impact on the course of underlying diseases, such as epilepsy, pain syndromes and post-stroke conditions. Modern approaches to the diagnosis and treatment of ADs in this group of patients are discussed. Special attention is given to the role of etifoxine as an effective anxiolytic in the comprehensive therapy of ADs. Etifoxine, due to its dual mechanism of action on GABA receptors, demonstrates high efficacy in reducing anxiety and has neuroprotective, neurotrophic, neuroplastic, analgesic, and anti-inflammatory properties, making it an important tool in the treatment of comorbid ADs in patients with neurological pathologies. The article also reviews recently published data confirming its efficacy and favourable safety profile compared to traditional benzodiazepines and other anxiolytic drugs.

Molecular mechanisms underlying major depressive disorder and post-stroke affective disorders

Two of the most common and incapacitating mental health disorders around the world are major depressive disorder (MDD) and post-stroke depression (PSD). MDD is thought to result from abnormal connectivity between the monoaminergic, glutamatergic, GABAergic, and/or cholinergic pathways. Additional factors include the roles of hormonal, immune, ageing, as well as the influence of cellular, molecular, and epigenetics in the development of mood disorders. This complexity of factors has been anticipated by the Swiss psychiatrists Paul Kielholz and Jules Angst who introduced a multimodal treatment of MDD. Depression is the predominant mood disorder, impacting around one-third of individuals who have experienced a stroke. MDD and PSD share common underlying biological mechanisms related to the disruption of monoaminergic pathways. The major contributor to PSD is the stroke lesion location, which can involve the disruption of the serotoninergic, dopaminergic, glutamatergic, GABAergic, or cholinergic pathways. Additionally, various other disorders such as mania, bipolar disorder, anxiety disorder, and apathy might occur post-stroke, although their prevalence is considerably lower. However, there are differences in the onset of MDD among mood disorders. Some mood disorders develop gradually and can persist for a lifetime, potentially culminating in suicide. In contrast, PSD has a rapid onset because of the severe disruption of neural pathways essential for mood behavior caused by the lesion. However, PSD might also spontaneously resolve several months after a stroke, though it is associated with higher mortality. This review also provides a brief overview of the treatments currently available in medical practice.

Effects of multicomponent exercise on quality of life, depression and anxiety among stroke survivors: A systematic review and meta-analysis

BACKGROUND

Current guidelines stress the importance of exercise, especially multicomponent exercise to older adults with chronic conditions.

AIM

To critically synthesise evidence that evaluates the effects of multicomponent exercise on quality of life, depression and anxiety after stroke.

DESIGN

Systematic review and meta-analysis followed the PRISMA 2020 statement.

METHODS

A systematic search of PubMed, Embase, Web of Science, Cochrane Library, CINAHL and PsycINFO from inception to 12 June 2023 was performed. Risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2). Meta-analyses were conducted using Review Manager 5.4 and narrative syntheses were adopted whenever meta-analysis was inappropriate. The overall certainty of the evidence was rated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

RESULTS

Of 15,351 records identified, nine were eligible and data were available for seven randomised controlled trials, three of which were identified as having a high risk of bias, one as low risk, and five as having some concerns. Subgroup pooled analyses indicated that multicomponent exercise engaged in longer exercise sessions (>60 min) was effective in improving quality of life immediately post-intervention and through 3-6 months post-intervention. However, multicomponent exercise did not significantly affect depression and anxiety.

CONCLUSIONS

Multicomponent exercise with longer duration of exercise sessions has promising effects on both short- to medium-term quality of life among stroke survivors.

PATIENT OR PUBLIC CONTRIBUTION

This does not apply to our work as it is a review paper.

RELEVANCE TO CLINICAL PRACTICE

Healthcare providers could consider encouraging the patients to participate in multicomponent exercise sessions for more than 60 min. It is important to note that stroke survivors should be supervised by trained personnel at the beginning of the training.

REGISTRATION

The protocol was registered on PROSPERO.

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.

Longitudinal change of six common inflammatory cytokines and their relationship to anxiety, depression, and cognitive impairment in acute ischemic stroke patients

Inflammatory cytokines are known to be involved in acute ischemic stroke (AIS), while the relationship of multiple inflammatory cytokines with mental disorders in AIS is less reported. This research intended to explore the longitudinal variation of common inflammatory cytokines and their correlation with anxiety, depression, and cognitive impairment in AIS patients. Six inflammatory cytokines were detected by enzyme-linked immunosorbent assay among 175 AIS patients at admission (baseline) and on the day (D)1, D3, and D7 after admission. Anxiety, depression, and cognition were evaluated using the Hospital Anxiety and Depression Scale and Mini-Mental State Examination at discharge, respectively. Anxiety, depression, and cognitive impairment rates were 32.6, 39.4, and 19.4%, respectively. Tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, IL-8, and IL-17A increased from baseline to D1, then decreased from D1 to D7 (all P<0.001), while IL-10 presented an opposite trend (P<0.001). Interestingly, TNF-α on D1 and D3, IL-6 on D3, IL-8 on D3 and D7, and IL-17A on D1, D3, and D7 correlated with higher anxiety rate (all P<0.05). TNF-α on D1, D3, and D7, IL-8 at baseline, D1, D3, and D7, IL-17A on D1 and D7 correlated with increased depression rate (all P<0.05). In addition, IL-1β on D1 and IL-17 at baseline, D1, D3, and D7 correlated with elevated cognitive-impairment rate (all P<0.05). Inflammatory cytokines were dysregulated after disease onset, and their longitudinal change correlated with psychological issues in AIS patients.

Stroke, depression, and self-harm in later life

PURPOSE OF THE REVIEW

To examine recently published results of randomized placebo-controlled trials investigating the clinical effects of selective serotonin reuptake inhibitors on the prevalence of clinically significant symptoms of depression and suicidal ideation after an acute stroke.

RECENT FINDINGS

The prevalence of poststroke depression varies markedly according to the approach used to define depression, with recently published data suggesting that about one in every three stroke survivors will experience clinically significant symptoms of depression over a period of 12 months. The proportion of stroke survivors with clinically significant symptoms of depression decreases progressively with time, but in 30% of them symptoms persist or recur over 12 months. Routine daily treatment with 20 mg of fluoxetine for 6 months does not affect the prevalence of depression in this population, nor is it effective at treating or preventing poststroke depressive symptoms. Treatment discontinuation, gastrointestinal adverse effects, seizures and bone fractures are more frequent among stroke survivors treated with antidepressants than placebo. Moreover, current data show that thoughts about death or suicide are more frequent among adults who had a stroke than the general population, although recurring suicidal thoughts are uncommon. Routine daily treatment with 20 mg of fluoxetine for 6 months does not change the proportion of people who disclose suicidal thoughts over a period of 12 months after an acute stroke.

SUMMARY

Current evidence raises concerns about the efficacy and safety of antidepressants for the management and prevention of poststroke clinically significant symptoms of depression. It is unclear if these findings can be generalized to people with severe strokes or to stroke survivors with moderate to severe major depressive episodes.

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.

2023 Guideline for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage: A Guideline From the American Heart Association/American Stroke Association

AIM

The "2023 Guideline for the Management of Patients With Aneurysmal Subarachnoid Hemorrhage" replaces the 2012 "Guidelines for the Management of Aneurysmal Subarachnoid Hemorrhage." The 2023 guideline is intended to provide patient-centric recommendations for clinicians to prevent, diagnose, and manage patients with aneurysmal subarachnoid hemorrhage.

METHODS

A comprehensive search for literature published since the 2012 guideline, derived from research principally involving human subjects, published in English, and indexed in MEDLINE, PubMed, Cochrane Library, and other selected databases relevant to this guideline, was conducted between March 2022 and June 2022. In addition, the guideline writing group reviewed documents on related subject matter previously published by the American Heart Association. Newer studies published between July 2022 and November 2022 that affected recommendation content, Class of Recommendation, or Level of Evidence were included if appropriate. Structure: Aneurysmal subarachnoid hemorrhage is a significant global public health threat and a severely morbid and often deadly condition. The 2023 aneurysmal subarachnoid hemorrhage guideline provides recommendations based on current evidence for the treatment of these patients. The recommendations present an evidence-based approach to preventing, diagnosing, and managing patients with aneurysmal subarachnoid hemorrhage, with the intent to improve quality of care and align with patients' and their families' and caregivers' interests. Many recommendations from the previous aneurysmal subarachnoid hemorrhage guidelines have been updated with new evidence, and new recommendations have been created when supported by published data.

Application of vagus nerve stimulation on the rehabilitation of upper limb dysfunction after stroke: a systematic review and meta-analysis

Objective

This study aimed to elucidate the efficacy, safety, and long-term implications of vagus nerve stimulation (VNS) as a viable therapeutic option for patients with upper limb dysfunction following a stroke.

Methods

Data from the following libraries were searched from inception to December 2022: PubMed, Wanfang, Scopus, China Science and Technology Journal Database, Embase, Web of Science, China Biology Medicine Disc, Cochrane Library, and China National Knowledge Infrastructure. Outcomes included indicators of upper limb motor function, indicators of prognosis, and indicators of safety (incidence of adverse events [AEs] and serious AEs [SAEs]). Two of the authors extracted the data independently. A third researcher arbitrated when disputes occurred. The quality of each eligible study was evaluated using the Cochrane Risk of Bias tool. Meta-analysis and bias analysis were performed using Stata (version 16.0) and RevMan (version 5.3).

Results

Ten trials (VNS combined with rehabilitation group vs. no or sham VNS combined with rehabilitation group) with 335 patients were included in the meta-analysis. Regarding upper extremity motor function, based on Fugl-Meyer assessment scores, VNS combined with other treatment options had immediate (mean difference [MD] = 2.82, 95% confidence interval [CI] = 1.78-3.91, I² = 62%, p < 0.00001) and long-term (day-30 MD = 4.20, 95% CI = 2.90-5.50, p < 0.00001; day-90 MD = 3.27, 95% CI = 1.67-4.87, p < 0.00001) beneficial effects compared with that of the control treatment. Subgroup analyses showed that transcutaneous VNS (MD = 2.87, 95% CI = 1.78-3.91, I² = 62%, p < 0.00001) may be superior to invasive VNS (MD = 3.56, 95% CI = 1.99-5.13, I² = 77%, p < 0.0001) and that VNS combined with integrated treatment (MD = 2.87, 95% CI = 1.78-3.91, I² = 62%, p < 0.00001) is superior to VNS combined with upper extremity training alone (MD = 2.24, 95% CI = 0.55-3.93, I² = 48%, p = 0.009). Moreover, lower frequency VNS (20 Hz) (MD = 3.39, 95% CI = 2.06-4.73, I² = 65%, p < 0.00001) may be superior to higher frequency VNS (25 Hz or 30 Hz) (MD = 2.29, 95% CI = 0.27-4.32, I² = 58%, p = 0,03). Regarding prognosis, the VNS group outperformed the control group in the activities of daily living (standardized MD = 1.50, 95% CI = 1.10-1.90, I² = 0%, p < 0.00001) and depression reduction. In contrast, quality of life did not improve (p = 0.51). Safety was not significantly different between the experimental and control groups (AE p = 0.25; SAE p = 0.26).

Conclusion

VNS is an effective and safe treatment for upper extremity motor dysfunction after a stroke. For the functional restoration of the upper extremities, noninvasive integrated therapy and lower-frequency VNS may be more effective. In the future, further high-quality studies with larger study populations, more comprehensive indicators, and thorough data are required to advance the clinical application of VNS.

Associations Between Vascular Risk Factor Levels and Cognitive Decline Among Stroke Survivors

Importance

Incident stroke is associated with accelerated cognitive decline. Whether poststroke vascular risk factor levels are associated with faster cognitive decline is uncertain.

Objective

To evaluate associations of poststroke systolic blood pressure (SBP), glucose, and low-density lipoprotein (LDL) cholesterol levels with cognitive decline.

Design, Setting, and Participants

Individual participant data meta-analysis of 4 US cohort studies (conducted 1971-2019). Linear mixed-effects models estimated changes in cognition after incident stroke. Median (IQR) follow-up was 4.7 (2.6-7.9) years. Analysis began August 2021 and was completed March 2023.

Exposures

Time-dependent cumulative mean poststroke SBP, glucose, and LDL cholesterol levels.

Main Outcomes and Measures

The primary outcome was change in global cognition. Secondary outcomes were change in executive function and memory. Outcomes were standardized as t scores (mean [SD], 50 [10]); a 1-point difference represents a 0.1-SD difference in cognition.

Results

A total of 1120 eligible dementia-free individuals with incident stroke were identified; 982 (87.7%) had available covariate data and 138 (12.3%) were excluded for missing covariate data. Of the 982, 480 (48.9%) were female individuals, and 289 (29.4%) were Black individuals. The median age at incident stroke was 74.6 (IQR, 69.1-79.8; range, 44.1-96.4) years. Cumulative mean poststroke SBP and LDL cholesterol levels were not associated with any cognitive outcome. However, after accounting for cumulative mean poststroke SBP and LDL cholesterol levels, higher cumulative mean poststroke glucose level was associated with faster decline in global cognition (-0.04 points/y faster per each 10-mg/dL increase [95% CI, -0.08 to -0.001 points/y]; P = .046) but not executive function or memory. After restricting to 798 participants with apolipoprotein E4 (APOE4) data and controlling for APOE4 and APOE4 × time, higher cumulative mean poststroke glucose level was associated with a faster decline in global cognition in models without and with adjustment for cumulative mean poststroke SBP and LDL cholesterol levels (-0.05 points/y faster per 10-mg/dL increase [95% CI, -0.09 to -0.01 points/y]; P = .01; -0.07 points/y faster per 10-mg/dL increase [95% CI, -0.11 to -0.03 points/y]; P = .002) but not executive function or memory declines.

Conclusions and Relevance

In this cohort study, higher poststroke glucose levels were associated with faster global cognitive decline. We found no evidence that poststroke LDL cholesterol and SBP levels were associated with cognitive decline.

Biological, Psychiatric, Psychosocial, and Cognitive Factors of Poststroke Depression

BACKGROUND

Depression is the most common psychiatric condition that occurs after cerebrovascular accident, especially within the first year after stroke. Poststroke depression (PSD) may occur due to environmental factors such as functional limitations in daily activities, lower quality of life, or biological factors such as damage to areas in the brain involved in emotion regulation. Although many factors are hypothesized to increase the risk of PSD, the relative contribution of these factors is not well understood.

PURPOSE

We evaluated which cross-sectional variables were associated with increased odds of PSD in our adult outpatient stroke neuropsychology clinic population.

METHODS

The sample included 325 patients (49.2% female; mean age of 59-years old) evaluated at an average of 8.1 months after an ischemic or hemorrhagic stroke. Variables included in logistic regression were stroke characteristics, demographics, psychosocial factors, comorbid medical problems, comorbid psychiatric conditions, and cognitive status. The Mini International Neuropsychiatric Inventory was used to determine DSM-defined PSD and anxiety disorders. A standard neuropsychological test battery was administered.

RESULTS

PSD occurred in 30.8% of the sample. Logistic regression indicated that increased odds of PSD were associated with a comorbid anxiety disorder (5.9 times more likely to suffer from PSD, p < 0.001). Further, increased odds of PSD were associated with a history of depression treatment before stroke (3.0 times more likely to suffer from PSD), fatigue (2.8 times more likely), memory impairment (2.4 times more likely), and younger age at stroke (all p values < 0.006).

DISCUSSION

Results suggest that PSD is likely multifactorial and extends the literature by demonstrating that a comorbid anxiety disorder correlated strongest with PSD. Poststroke screening and treatment plans should address not only depression but comorbid anxiety.

Nomogram including indirect bilirubin for the prediction of post-stroke depression at 3 months after mild acute ischemic stroke onset

Background

Post-stroke depression (PSD) has been proven to be associated with stroke severity. Thus, we hypothesized that the prevalence of PSD would be lower in patients with mild stroke. We aim to explore predictors of depression at 3 months after mild acute ischemic stroke (MAIS) onset and to develop a practical and convenient prediction model for the early identification of patients at high risk.

Methods

A total of 519 patients with MAIS were consecutively recruited from three hospitals in Wuhan city, Hubei province. MAIS was defined as a National Institute of Health Stroke Scale (NIHSS) score of ≤5 at admission. Meeting the DSM-V diagnostic criteria and a 17-item Hamilton Rating Scale for Depression (HAMD-17) score of >7 at their 3-month follow-up were considered the primary outcomes. A multivariable logistic regression model was used to determine the factors adjusted for potential confounders, and all independent predictors were brought into the construction of a nomogram to predict PSD.

Results

The prevalence of PSD is up to 32% at 3 months after MAIS onset. After adjusting for potential confounders, indirect bilirubin (p = 0.029), physical activity (p = 0.001), smoking (p = 0.025), hospitalization days (p = 0.014), neuroticism (p < 0.001), and MMSE (p < 0.001) remained independently and significantly related with PSD. The concordance index (C-index) of the nomogram jointly constructed by the aforementioned six factors was 0.723 (95% CI: 0.678-0.768).

Conclusion

The prevalence of PSD seems equally high even if the ischemic stroke is mild, which calls for great concern from clinicians. In addition, our study found that a higher level of indirect bilirubin can lower the risk of PSD. This finding may provide a potential new approach to PSD treatment. Furthermore, the nomogram including bilirubin is convenient and practical to predict PSD after MAIS onset.

Psychopathological network for early-onset post-stroke depression symptoms

BACKGROUND

Post-stroke depression (PSD) can be conceptualized as a complex network where PSD symptoms (PSDS) interact with each other. The neural mechanism of PSD and interactions among PSDS remain to be elucidated. This study aimed to investigate the neuroanatomical substrates of, as well as the interactions between, individual PSDS to better understand the pathogenesis of early-onset PSD.

METHODS

A total of 861 first-ever stroke patients admitted within 7 days poststroke were consecutively recruited from three independent hospitals in China. Sociodemographic, clinical and neuroimaging data were collected upon admission. PSDS assessment with Hamilton Depression Rating Scale was performed at 2 weeks after stroke. Thirteen PSDS were included to develop a psychopathological network in which central symptoms (i.e. symptoms most strongly correlated with other PSDS) were identified. Voxel-based lesion-symptom mapping (VLSM) was performed to uncover the lesion locations associated with overall PSDS severity and severities of individual PSDS, in order to test the hypothesis that strategic lesion locations for central symptoms could significantly contribute to higher overall PSDS severity.

RESULTS

Depressed mood, Psychiatric anxiety and Loss of interest in work and activities were identified as central PSDS at the early stage of stroke in our relatively stable PSDS network. Lesions in bilateral (especially the right) basal ganglia and capsular regions were found significantly associated with higher overall PSDS severity. Most of the above regions were also correlated with higher severities of 3 central PSDS. The other 10 PSDS could not be mapped to any certain brain region.

CONCLUSIONS

There are stable interactions among early-onset PSDS with Depressed mood, Psychiatric anxiety and Loss of interest as central symptoms. The strategic lesion locations for central symptoms may indirectly induce other PSDS via the symptom network, resulting in higher overall PSDS severity.

Feasibility of a meditation intervention for stroke survivors and informal caregivers: a randomized controlled trial

BACKGROUND

Depressive symptoms are a significant psychological complication of stroke, impacting both survivors and informal caregivers of survivors. Randomized controlled trials are needed to determine optimal non-pharmacological strategies to prevent or ameliorate depressive symptoms in stroke survivors and their informal caregivers.

METHODS

A prospective, randomized, parallel-group, single-center, feasibility study. Participants were assigned to a 4-week meditation intervention or expressive writing control group. The intervention comprised four facilitator-led group meditation sessions, one session per week and building upon prior session(s). Descriptive statistics were used to examine the proportion of eligible individuals who enrolled, retention and adherence rates, and the proportion of questionnaires completed. Data were collected at baseline, immediately after the 4-week intervention period, and 4 and 8 weeks after the intervention period. Secondary analysis tested for changes in symptoms of depression (Center for Epidemiologic Studies-Depression [CES-D]), anxiety [State-Trait Anxiety Inventory for Adults (STAI)], and pain (Brief Pain Inventory-Short Form) in the intervention group via paired t tests. Linear mixed models were used to compare longitudinal changes in the measures between the groups. Intervention and trial design acceptability were preliminary explored.

RESULTS

Seventy-one (77%) individuals enrolled and 26 (37%) completed the study (baseline and 8-week post-intervention visits completed). Forty-two (66%) participants completed baseline and immediate post-intervention visits. Mean questionnaire completion rate was 95%. The median meditation group session attendance rate for the intervention group was 75.0%, and the mean attendance rate was 55%. Non-significant reductions in CES-D scores were found. Paired t tests for stroke survivors indicated a significant reduction from baseline through week 8 in BPI-sf severity scores (p = 0.0270). Repeated measures analysis with linear mixed models for informal caregivers indicated a significant reduction in in STAI-Trait scores (F [3,16.2] = 3.28, p = 0.0479) and paired t test showed a significant reduction from baseline to week 4 in STAI-Trait scores (mean = - 9.1250, 95% CI [- 16.8060 to 1.4440], p = 0.0262). No between-group differences were found.

CONCLUSIONS

Future trials will require strategies to optimize retention and adherence before definitive efficacy testing of the meditation intervention.

Effectiveness Evaluation of Repetitive Transcranial Magnetic Stimulation Therapy Combined with Mindfulness-Based Stress Reduction for People with Post-Stroke Depression: A Randomized Controlled Trial

Background: Post-stroke depression (PSD) is most prevalent during the rehabilitative period following a stroke. Recent studies verified the effects of repetitive transcranial magnetic stimulation therapy (rTMS) and mindfulness-based stress reduction (MBSR) in patients with depression. However, the effectiveness and prospect of application in PSD patients remain unclear. This study sought to evaluate the effectiveness of a combined intervention based on rTMS and MBSR for the physical and mental state of PSD patients. Methods: A randomized, double-blind, sham-controlled study design was employed. Participants were recruited from the Rehabilitation Medicine Centre and randomly assigned to receive either MBSR combined with active or sham rTMS or sham rTMS combined with general psychological care. We used a 17-item Hamilton Depression Rating Scale (HAMD-17), a mini-mental state examination (MMSE), the Modified Barthel Index (MBI), and the Pittsburgh Sleep Quality Index (PSQI) to evaluate depressed symptoms, cognitive function, activities of daily living (ADL), and sleep quality at baseline, post-intervention, and the 8-week follow-up. A two-factor analysis of variance was used to compare differences between groups, and Pearson’s linear correlation was used to analyze the possible relationship between variables and potential predictors of depression improvement. Results: Seventy-two participants were randomized to rTMS−MBSR (n = 24), sham rTMS−MBSR (n = 24), or sham rTMS−general psychological care (n = 24). A total of 71 patients completed the questionnaire, a 99% response rate. There were significant time and group interaction effects in HAMD-17, MMSE, MBI, and PSQI scores (p < 0.001). The repeated-measure ANOVA showed a significant improvement of all variables in rTMS−MBSR compared to sham rTMS−MBSR and sham rTMS combined with general psychological care (p < 0.05). Additional results demonstrated that cognitive function, sleep quality, and activities of daily living are associated with depressive symptoms, and cognitive function is a potential variable for improved depression. Conclusion: Depressive symptoms can be identified early by assessing cognitive function, and rTMS−MBSR might be considered a potentially helpful treatment for PSD.

[Emotional disorders after stroke]

Emotional disorders are common among patients after stroke. They include anger, fear, emotional expression control (uncontrollable crying, laughing), emotional indifference (apathy), disorders of emotion recognition and emotional empathy. They might develop independently or as a presentation of depression, anxiety, catastrophic reaction, posttraumatic stress disorder etc. Treatment of post-stroke emotional disorders include pharmacotherapy, psychotherapy, neuromodulation.

Effectiveness of mindfulness-based stress reduction and mindfulness-based cognitive therapy on depression in poststroke patients-A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

To evaluate the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) on depressive symptoms in people with stroke.

METHODS

The PubMed, CINAL, Web of Science, Embase, The Cochrane Library, CNKI, and Wangfang databases were searched for relevant articles from inception to September 1st, 2022. Only randomized controlled trials (RCTs) examining the effect of MBSR and MBCT on depressive symptoms in poststroke patients were included. Data extraction and critical appraisal were conducted independently by two investigators.

RESULTS

Seven trials with 502 participants were included. Using standardized mean differences, the meta-analysis showed evidence of a significant effect in depression (SMD = -0.93, 95% CI (-1.34 to -0.53), Z = 4.48, p < 0.001). MBSR and MBCT both affected depressive emotions in poststroke participants with depression (SMD = -1.27, 95% CI (-1.71 to -0.84), p < 0.001) and poststroke participants without clinically defined depression (SMD = -0.46, 95% CI (-0.75 to -0.17), p = 0.002).

CONCLUSION

Although populations with stroke seem to potentially improve moods from MBSR/MBCT intervention, the impact on the physiological parameters of the disease has not been determined. Further studies with long-term follow-up and higher qualities are warranted for such interventions to determine the full effectiveness.

Structural disconnection-based prediction of poststroke depression

Poststroke depression (PSD) is a common complication of stroke. Brain network disruptions caused by stroke are potential biological determinants of PSD but their conclusive roles are unavailable. Our study aimed to identify the strategic structural disconnection (SDC) pattern for PSD at three months poststroke and assess the predictive value of SDC information. Our prospective cohort of 697 first-ever acute ischemic stroke patients were recruited from three hospitals in central China. Sociodemographic, clinical, psychological and neuroimaging data were collected at baseline and depression status was assessed at three months poststroke. Voxel-based disconnection-symptom mapping found that SDCs involving bilateral temporal white matter and posterior corpus callosum, as well as white matter next to bilateral prefrontal cortex and posterior parietal cortex, were associated with PSD. This PSD-specific SDC pattern was used to derive SDC scores for all participants. SDC score was an independent predictor of PSD after adjusting for all imaging and clinical-sociodemographic-psychological covariates (odds ratio, 1.25; 95% confidence interval, 1.07, 1.48; P = 0.006). Split-half replication showed the stability and generalizability of above results. When added to the clinical-sociodemographic-psychological prediction model, SDC score significantly improved the model performance and ranked the highest in terms of predictor importance. In conclusion, a strategic SDC pattern involving multiple lobes bilaterally is identified for PSD at 3 months poststroke. The SDC score is an independent predictor of PSD and may improve the predictive performance of the clinical-sociodemographic-psychological prediction model, providing new evidence for the brain-behavior mechanism and biopsychosocial theory of PSD.

Telestroke’s Role Through the COVID-19 Pandemic and Beyond

Purpose of review

The goal of this paper is to discuss the role and utilization of telestroke services through the COVID-19 pandemic and to suggest future directions to sustain and increase patients’ access to stroke expertise.

Recent findings

Telestroke is an innovative and effective tool that has been shown to improve access, quality of care, and outcomes of patients with acute stroke syndromes in resource-limited areas for the last two decades. The COVID-19 pandemic posed a significant challenge and strained healthcare systems worldwide, but it created novel and unique opportunities to expand and increase the utilization of telehealth and telestroke services to deliver personalized healthcare across the continuum of stroke care outside of traditional settings. This rapid and widespread increase in telestroke use was facilitated by the removal of many legislative and regulatory barriers which have limited patients’ access to stroke expertise for many years.

Summary

As the public health emergency ends, there exists a unique opportunity to optimize and expand upon the pandemic-related rapid growth of telestroke care. Optimal utilization of telehealth and telestroke services will depend on maintaining and improving required infrastructure, laws, and regulations, particularly those governing reimbursement and licensing.
