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

Home and workforce reintegration one year after thrombectomy in acute stroke patients

INTRODUCTION

Endovascular thrombectomy (EVT) combined with intravenous thrombolysis is the current standard treatment for acute large-vessel occlusion stroke. Beyond clear clinical benefits in the acute and post-acute phases, comprehensive evaluations of long-term outcomes, including home and workforce reintegration, remain limited. This study aimed to assess home and workforce reintegration 1 year post-EVT in a cohort of acute stroke patients and explore their association with health-related quality of life (HRQoL).

PATIENTS AND METHODS

We conducted a prospective observational study of 404 patients undergoing EVT at a tertiary university medical center between October 2019 and December 2021. Patients' functional outcomes were evaluated using the modified Rankin Scale (mRS), and HRQoL was assessed via the European Quality of Life Five Dimension Scale (EQ-5D). Data on occupational and living status were collected through standardized telephone interviews at 3- and 12-months post-treatment.

RESULTS

Of 357 patients with 12-month follow-up data, 33.6% had a favorable outcome (mRS 0-2). Among stroke survivors, the rate of home reintegration without nursing care was 42.1%, and workforce reintegration among previously employed patients was 43.3% at 12 months. Both outcomes were significantly associated with improved HRQoL. Lower neurological deficits and younger age were predictive of successful home and workforce reintegration.

DISCUSSION AND CONCLUSION

One year post-EVT, approximately 40%-50% of acute stroke patients successfully reintegrate into home and work settings. These findings underscore the need for ongoing support tailored to improving long-term reintegration and quality of life for stroke survivors.

Neuronal HIPK2-HDAC3 axis regulates mitochondrial fragmentation to participate in stroke injury and post-stroke anxiety like behavior

Post-stroke anxiety (PSA) seriously affects the prognosis of patients, which is an urgent clinical problem to be addressed. However, the pathological mechanism of PSA is largely unclear. Here, we found that neuronal HIPK2 expression was upregulated in the ischemic lesion after stroke. The upregulation of HIPK2 promotes Drp1 oligomerization through the HDAC3-dependent pathway, leading to excessive mitochondrial damage. This subsequently triggers the release of cellular cytokines such as IL-18 from neurons under ischemic stress. Microglia are capable of responding to IL-18, which promotes their activation and enhances their phagocytosis, ultimately resulting in the loss of synapses and neurons, thereby exacerbating the pathological progression of PSA. HIPK2 knockdown or inhibition suppresses excessive pruning of neuronal synapses by activated microglia in the contralateral vCA1 region to compromise inactivated anxiolytic pBLA-vCA1Calb1+ circuit, relieving anxiety-like behavior after stroke. Furthermore, we discovered that early remimazolam administration can remodel HIPK2-HDAC3 axis, ameliorating the progression of PSA. In conclusion, our study revealed that the neuronal HIPK2-HDAC3 axis in the ischemic focus regulates mitochondrial fragmentation to balance inflammation stress reservoir to participate in anxiety susceptibility after stroke.

"I just kept asking and asking and there was nothing": re-thinking community resources & supports for young adult stroke survivors

PURPOSE

Stroke is often regarded as a disease of the elderly. However, 10-15% of strokes occur in people aged 18 to 50, and rates continue to rise. Young stroke survivors face unique challenges due to their occupational, family and personal commitments, which current stroke rehabilitation services may not fully address. Our qualitative study aimed to identify gaps in patient care and resources for young stroke survivors. We used these findings to develop recommendations to inform clinical care, healthcare system design, and health policy.

METHODS

Using Interpretive Description, we conducted semi-structured interviews with 19 stroke survivors aged 18-55 living in British Columbia, Canada, to explore their experiences during stroke recovery and assess current gaps in support and resources. We applied broad-based coding and thematic analysis to the transcripts.

RESULTS

Key themes included: (1) the need for longitudinal medical follow-up and information provision, (2) the need for psychological/psychiatric care, (3) the need to adapt community supports and resources to young survivors, and (4) the need to centralize and integrate community stroke services and resources.

CONCLUSION

Young stroke survivors experience unique challenges and lack appropriate services and resources. Many of our findings may be representative of remediable gaps that persist nationally and internationally.

Increased risk of depression and associated symptoms in poststroke aphasia

Poststroke aphasia hinders patients' emotional processing and social adaptation. This study estimated the risks of depression and related symptoms in patients developing or not developing aphasia after various types of stroke. Using data from the US Collaborative Network within the TriNetX Diamond Network, we conducted a retrospective cohort study of adults experiencing their first stroke between 2013 and 2022. Diagnoses were confirmed using corresponding International Classification of Diseases, Tenth Revision, Clinical Modification codes. Patients were stratified by poststroke aphasia status and stroke type, with propensity score matching performed to control for confounders. The primary outcome was depression within one year post-stroke; secondary outcomes included anxiety, fatigue, agitation, emotional impact, and insomnia. Each matched group comprised 12,333 patients. The risk of depression was significantly higher in patients with poststroke aphasia (hazard ratio: 1.728; 95% CI 1.464-2.038; p < 0.001), especially those with post-hemorrhagic-stroke aphasia (hazard ratio: 2.321; 95% CI 1.814-2.970; p < 0.001). Patients with poststroke aphasia also had higher risks of fatigue, agitation, and emotional impact. Anxiety and insomnia risks were higher in those with post-hemorrhagic-stroke aphasia. Poststroke aphasia, particularly post-hemorrhagic-stroke aphasia, may increase the risks of depression and associated symptoms, indicating the need for comprehensive psychiatric assessments.

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.

Safety-Seeking Behaviors and Anxiety Maintenance in People With Aphasia: A Viewpoint

PURPOSE

People with aphasia (PWA) often experience higher levels of anxiety and social isolation than people without aphasia. Although the presence of anxiety is appreciated in PWA, literature examining the etiology and persistent nature of anxiety in PWA is underdeveloped. Safety-seeking behaviors, or maladaptive acts used by individuals to decrease anxiety from a feared outcome, have been reported as key facilitators of long-term anxiety toward feared situations across a variety of clinical populations. The purpose of this viewpoint is to explore the concept of safety-seeking behaviors and discuss their potential relevance to the maintenance of anxiety in PWA. We further discuss the distinction between maladaptive (i.e., safety seeking) and adaptive (i.e., coping) behaviors and how this knowledge may improve the quality of clinical services for PWA.

CONCLUSIONS

The present review advocates for further exploration of the safety-seeking behaviors that are used by PWA. Until critical attention is given to this subject, clinicians may remain ill-equipped to identify and depict whether a self-management strategy is facilitative or inhibitive to PWA's communicative participation goals. Critically, a behavior that may be "maladaptive" for one individual may be "adaptive" for another. Future research should seek to identify common behavioral and cognitive strategies that PWA implement to reduce acute perceptions of anxiety. This knowledge may help facilitate holistic aphasia rehabilitation by allowing clinicians to foster conversations around behaviors that inhibit or promote successful communicative participation.

Delirium in acute stroke is associated with increased cognitive and psychiatric symptoms over time: The Nor-COAST study

BACKGROUND

Delirium, an acute and fluctuating mental disturbance of attention, cognition, and consciousness, commonly occurs in acute stroke. Research on long-term outcomes of stroke patients experiencing delirium is limited, especially regarding cognitive and psychiatric symptoms.

METHODS

As part of the Nor-COAST study, 373 patients were screened for delirium using the Confusion Assessment Method (CAM) in the acute phase of stroke. Patients were included in the mixed-model linear regression analyses if they had available data from the follow-ups at three, 18 or 36 months, totaling 334 (44.6 % women, mean (SD) age: 72.1 (12.5) years, 17 (5.1 %) diagnosed with delirium). Global cognition was measured using the Montreal Cognitive Assessment (MoCA). Psychiatric symptoms were measured using the Hospital Anxiety and Depression Scale (HADS) and the Neuropsychiatric Inventory-Questionnaire (NPI-Q).

RESULTS

At three months, delirium was associated with a higher NPI-Q score (Mean (SD) 2.9 (3.6) vs 1.4 (2.2)). At 18 and 36 months, delirium was associated with a lower MoCA score (Mean (SD) 19.7 (6.6) vs 24.3 (5.0), and 20.6 (7.6) vs 24.6 (4.8)), higher HADS anxiety symptoms (5.0 (4.3) vs 3.3 (3.3), and 5.9 (4.1) vs 3.4 (3.6)), higher HADS depression symptoms (7.2 (4.7) vs 3.4 (3.3), and 6.6 (5.1) vs 3.7 (3.7)), and higher NPI-Q score (2.4 (4.4) vs 1.7 (2.3), 2.6 (4.5) vs 1.0 (1.9)). Delirium significantly predicted the psychiatric symptoms hallucinations and agitation.

CONCLUSIONS

Patients with delirium in the acute phase of stroke may be particularly vulnerable to developing cognitive and psychiatric symptoms in the chronic phase.

Depression and anxiety as predictors of performance status and life satisfaction in older adult neurological patients: a cross-sectional cohort study

Neurological disorders are one of the leading causes of disability globally. Studies emphasise that the course and effectiveness of rehabilitation interventions may be influenced by emotional factors. The aim of the present study was to assess the prevalence of depressive and anxiety symptoms in patients with neurological disorders and examine whether depression and tendency to respond with anxiety are predictors of disability in these patients. The study included 229 individuals with neurological disorders aged over 55. Our findings show that stroke patients are more likely to experience depressive symptoms and are more likely to display trait anxiety as compared with patients with other neurological disorders. Advanced age, female sex, low level of education and the presence of trait anxiety are associated with a higher severity of depressive symptoms. Stroke survivors have significantly poorer ECOG performance scores and are more likely to be incapable for work. Both depression and trait anxiety are significant predictors of neurological patients' performance status, and the presence of depressive symptoms is a determinant of these patients' level of satisfaction with life. An understanding of psychological risk factors for poorer performance status in individuals with neurological disorders will make it possible to plan prophylactic interventions in order to minimise negative health impacts and facilitate access to mental health facilities.

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.

Effective evaluations of community nursing on rehabilitation for stroke survivors: A meta-analysis

BACKGROUND

Long-term rehabilitation of stroke survivors is often difficult and new tools to improve quality of life should be proposed. Community nursing can be a cost-effective tool to positively impact the lives of stroke survivors. This meta-analysis aimed to comprehensively evaluate the effects of community nursing on rehabilitation for stroke survivors.

METHODS

The Cochrane Library, PubMed, Web of Science, CINAHL Plus, Embase, PEDro, China Knowledge Resource Integrated Database (CNKI), WANFANG, and WEIPU databases were comprehensively searched from their inception to April 18, 2023. The revised Cochrane risk-of-bias tool for RCTs(RoB 2 tool) was used to assess the quality of the included studies. Meta-analysis was conducted using the Stata 12.0 software package and Review Manager v5.3 software.

RESULTS

A total of 25 randomized controlled trials with 2537 participants were included in the meta-analysis. Compared with the control group, community nursing combined with routine nursing had a significantly superior effect on the Barthel Index(BI), Fugl-Meyer(FMA), National Institutes of Health Stroke Scale(NIHSS), Self-rating Anxiety Scale(SAS), and Self-rating Depression Scale(SDS) scores for stroke survivors (BI: MD: 18.48, 95 % CI [16.87, 20.08], P < 0.00001; FMA: MD: 12.61, 95 % CI [10.44, 14.78], P < 0.00001; NIHSS: MD: -2.94, 95 % CI [-3.50, -2.37], P < 0.00001; SAS: MD: -8.19; 95 % CI: [-9.46, -6.92], P < 0.00001; SDS: MD: -6.46 95 % CI [-7.23, -5.70], P < 0.00001). Subgroup analysis demonstrated that routine nursing, health education, exercise rehabilitation nursing and psychological nursing combined with different community nursing measures were significant in rehabilitation for stroke survivors and there was no heterogeneous in the studies of each subgroup(P > 0.1, I2 < 50 %).

CONCLUSION

This meta-analysis demonstrated that community nursing combined with routine nursing might improve activities of daily living, motor function and nerve function, and relieve anxiety and depression in stroke survivors. Overall, community nursing had a significant effect on rehabilitation of stroke survivors. However, this study still has limitations such as the overestimation effects caused by the sample size and the risk of bias caused by interventions. Future research will attempt to overcome these limitations and comprehensively assess the effect of community nursing on the rehabilitation of stroke survivors.

Using virtual reality to manage pain and anxiety during dental treatments in patients with stroke: A case series

Dental anxiety is common post-stroke, with many patients unable to receive standard anesthetics. Virtual reality has been increasingly used to manage pain and anxiety in dentistry, though its use in individuals with stroke is largely unexplored. A case series of two patients with a history of stroke and dental anxiety was conducted at a specialized dental clinic. Patients watched 360°-virtual reality videos in a dental chair using a head-mounted display. Outcomes (patient: dental anxiety and pain, reactions to virtual reality; dental team: system usability, impact on workflow) were assessed using a standard observation tool, questionnaires, and interviews. Both patients wore virtual reality throughout the procedure and reported that the device was comfortable, provided a distraction, and had potential to reduce anxiety/pain. The dentist reported a positive impact on patient anxiety and time to complete procedures, and intends to continue using virtual reality with other stroke patients and clinical populations.

Development of a patient-centered transition program for stroke survivors and their informal caregivers, combining case-management and access to an online information platform: A user-centered design approach

Background

During the hospital-to-home transition, stroke survivors and their caregivers face a significant lack of support and information which impacts their psychosocial recovery. We aimed to co-design a program combining individual support by a trained case-manager (dedicated professional providing individual support) and an online information platform to address needs of stroke survivors and caregivers.

Methods

A two-step methodology was used. The first step followed a "user-centered design" approach during four workshops with stroke survivors, caregivers, and healthcare professionals to develop the platform and define the case-manager profile. The second step was a usability test of the platform following a Think Aloud method with patients and caregivers. The workshops and interviews were analyzed following a qualitative thematic analysis. The analysis of Think Aloud interviews was based on User Experience Honeycomb framework by Morville.

Results

Eight participants attended the workshops: two patients, two caregivers, three nurses, and a general practitioner. Activities, training, and skills of the case-manager were defined according to stroke survivors and caregivers needs. Name, graphics, navigation, and content of the platform were developed with the participants, a developer and a graphic designer. The usability of the platform was tested with 5 patients and 5 caregivers. The Think Aloud confirmed satisfaction with graphics and content but a need for improvement regarding the navigability. An update of the platform was conducted in order to answer the needs expressed by participants.

Conclusion

We developed, with a participatory approach, a patient-centered transition program, which will be evaluated in a randomized controlled trial.

What are the available online resources targeting psychosocial burden among stroke survivors and their informal caregivers: A scoping review

Background

After discharge home, stroke survivors and their informal caregivers face a significant lack of support and information which accentuates their psychosocial burden. Online resources might provide this support and address psychosocial needs, but existing online stroke programmes mainly target functional rehabilitation. We aimed to map the existing literature on online resources that have been evaluated in stroke rehabilitation and aimed at reducing psychosocial impact in stroke survivors and informal caregivers.

Methods

MEDLINE was searched (2010-2024) to identify studies investigating online resources targeting psychosocial health. Studies were selected and extracted independently by two reviewers. We described the content, use, and psychosocial impact of these interventions using a narrative approach.

Results

Eleven studies were included in the review, reporting 10 online resources (two studies relating to the same resource). Online resources were heterogeneous: eight information/resources websites, one mobile app, and one forum. Five online resources were dedicated to stroke survivors, four to stroke survivors and their informal caregivers, and one to informal caregivers. Two randomized controlled trials reported a significant decrease in depressive symptoms associated with the use of online resources. Stroke survivors and informal caregivers find online resources useful and acceptable to address their psychosocial needs.

Conclusions

Few online stroke resources have been designed and evaluated to support post-stroke psychosocial rehabilitation. Further larger-scale research needs to study the impact of these interventions on psychosocial recovery over time.

Evaluating the feasibility and acceptability of the Mood Assessment Post-Stroke (MAPS) mood screening training

Mood problems are common after stroke, and screening is recommended. Training may support staff knowledge and implementation of screening, but the feasibility of training programmes in the Australian healthcare system has not been formally established. This study aimed to assess the feasibility of a mood screening training for a multidisciplinary team (MDT) of stroke clinicians working in a post-acute inpatient rehabilitation service.Twelve staff from a rehabilitation service at a major hospital in Sydney, Australia participated in a 3-h interactive training session. The feasibility of running the course, assessment of knowledge gained via a consolidation exercise and quiz and acceptability of the training were assessed via focus groups.The in-person modality of the training hindered recruitment and assessment of participants' knowledge, though the actual measures themselves appeared appropriate. Nine participants provided feedback in two focus groups. Thematic analysis identified positive reactions to the training. However, low self-efficacy persisted and organisational/socio-cultural barriers to implementation emerged. Following training, the medical officers of the MDT had successfully implemented routine screening.Overall, the training appeared acceptable and to foster knowledge in staff. However, limitations to recruitment and administering evaluations were identified. The development of flexible online training may improve future evaluations of screening training programmes/pathways.

An observational, cross-sectional and monocentric study assessing psychological and cognitive features as main predictors of psychological well-being in stroke survivors

Well-being is a relevant outcome after stroke, potentially impacted by mental health difficulties. We addressed the psychological and cognitive predictors of psychological well-being in a sample of 122 stroke survivors (75 males, 97 with ischemic stroke; mean age 64.1, mean NIHSS 2.9, mean distance from the acute event 5.1 years) admitted to the 'Carlo Besta' Neurological Institute. Trait anxiety (β = -0.257), state anxiety (β = -0.208) and symptoms of depression (β = -0.484) significantly predicted well-being variation (Adj. R2 = 0.687). These potentially modifiable factors are promising targets for interventions to reduce the burden of illness and enhance the recovery process.

Combined Cognitive and Psychological Interventions Improve Meaningful Outcomes after Acquired Brain Injury: A Systematic Review and Meta-Analysis

Interventions addressing cognitive and emotional difficulties after acquired brain injury (ABI) often focus on specific impairments in cognition or mood. These interventions can be effective at addressing their specific target, but do not routinely translate to improved activity and participation outcomes. Approaches that combine cognitive and psychological rehabilitation are increasingly popular; however, to date, there have been no systematic evaluations of their efficacy. We conducted a systematic review of five databases, searching for randomised controlled trials of adults with diagnoses of non-progressive ABI at least 1-month post injury, in receipt of interventions that combined cognitive and psychological components compared to any control. Screening and data extraction were evaluated by two independent reviewers using a standardised protocol. Effect sizes were calculated using Hedge's g and estimated using a random-effects model. Risk of bias was assessed using the PEDro-P rating system, and quality of evidence evaluated using the grading of recommendation, assessment, development and evaluation (GRADE) approach. Thirteen studies were included in the meta-analysis (n = 684). There was an overall small-to-medium effect (g = 0.42) for combined interventions compared with controls, with gains maintained at 6-month follow-up. Improvements were observed at the level of impairment, activity, participation and quality of life. GRADE ratings and analyses investigating sensitivity, heterogeneity and publication bias indicated that these effects were robust. No a priori variables moderated these effects. Overall, this review provides strong evidence that combined cognitive and psychological interventions create meaningful change in the lives of people with ABI.

The mediating role of anxiety in disease uncertainty and acute stress in acute ischaemic stroke patients in the post-epidemic era

Objective

To analyse the influencing factors of anxiety, disease uncertainty and acute stress response in patients with acute ischaemic stroke, and to verify the mediating role of anxiety in the post-epidemic era.

Methods

240 patients with acute ischaemic stroke were selected from a tertiary hospital in Wuhan City and investigated by questionnaire and convenience sampling methods.

Results

The total anxiety score, disease uncertainty and acute stress reaction were at moderate levels. Anxiety was positively correlated with illness uncertainty, and anxiety and acute stress response were negatively correlated. Multiple linear regression analysis showed that Sickness uncertainty, acute stress response, age, and work status influenced anxiety. Anxiety mediated the prediction of Sickness uncertainty and acute stress response, with the mediating effect accounting for 35.6% of the total effect.

Conclusion

Disease uncertainty in patients with acute ischaemic stroke in the post-epidemic era directly affects the acute stress response and indirectly through anxiety.

A cohort study on anxiety and perceived recovery 3 and 12 months after mild to moderate stroke

Background

Anxiety is a common complication of stroke, affecting one in every three stroke survivors. Stroke recovery is a dynamic process, with most recovery occurring within the first 3 months. However, how anxiety affects this dynamic remains unknown. Therefore, this study aimed to investigate how anxiety affects perceived recovery at 3 and 12 months after stroke. Additionally we also examined the change in perceived stroke recovery from 3 to 12 months and its relationship with anxiety.

Methods

In this longitudinal study patients with stroke were enrolled at Sahlgrenska University Hospital, Gothenburg, Sweden. The Hospital Anxiety and Depression Scale was used to assess anxiety, and the Stroke Impact Scale was used to assess perceived recovery 3 and 12 months after the stroke. The difference in perceived stroke recovery between the anxiety and no-anxiety groups at 3 and 12 months was analyzed. Changes in perceived stroke recovery were calculated and trichotomized from 3 to 12 months based on clinically significant positive changes (+10 points or more), clinically important negative changes (-10 points or less), or no changes (±9). At 3 and 12 months after the stroke, negative and positive recovery was compared to no change in recovery regarding anxiety scores.

Results

This study included 99 patients (44.4% female, median age, 77 years). At 3 and 12 months after the stroke, the median recovery score was 80 out of 100. At 3- and 12-months 17.6 and 15.7% of the patients experienced anxiety, respectively. At both time points, there was a significant association between anxiety and lower perceived stroke recovery (at 3 months: p < 0.001; and 12 months p = 0.002). Among participants with anxiety at 3 or 12 months after stroke, a positive change in recovery from 3 to 12 months was identified (3 months, p = 0.004 and 12 months, p = 0.0014).

Conclusion

Anxiety symptoms following a stroke are associated with lower levels of perceived stroke recovery for at least 1 year after the stroke. Identifying patients with anxiety early after stroke may be beneficial for identifying those at risk of lower recovery.Clinical trial registration:ClinicalTrials.gov, identifier [NCT01622205].

Explainable Risk Prediction of Post-Stroke Adverse Mental Outcomes Using Machine Learning Techniques in a Population of 1780 Patients

Post-stroke depression and anxiety, collectively known as post-stroke adverse mental outcome (PSAMO) are common sequelae of stroke. About 30% of stroke survivors develop depression and about 20% develop anxiety. Stroke survivors with PSAMO have poorer health outcomes with higher mortality and greater functional disability. In this study, we aimed to develop a machine learning (ML) model to predict the risk of PSAMO. We retrospectively studied 1780 patients with stroke who were divided into PSAMO vs. no PSAMO groups based on results of validated depression and anxiety questionnaires. The features collected included demographic and sociological data, quality of life scores, stroke-related information, medical and medication history, and comorbidities. Recursive feature elimination was used to select features to input in parallel to eight ML algorithms to train and test the model. Bayesian optimization was used for hyperparameter tuning. Shapley additive explanations (SHAP), an explainable AI (XAI) method, was applied to interpret the model. The best performing ML algorithm was gradient-boosted tree, which attained 74.7% binary classification accuracy. Feature importance calculated by SHAP produced a list of ranked important features that contributed to the prediction, which were consistent with findings of prior clinical studies. Some of these factors were modifiable, and potentially amenable to intervention at early stages of stroke to reduce the incidence of PSAMO.

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.

Depression and anxiety in acute ischemic stroke involving the anterior but not paramedian or inferolateral thalamus

Background and objectives

Emotional and cognitive deficits are prevalent in strokes involving the thalamus. In contrast to cognitive deficits, emotional deficits have not been studied prospectively in isolated thalamic stroke.

Methods

In 37 ischemic thalamic stroke patients (57.0 [50.0; 69.5] years [median (Q1; Q3)], 21 males, 5 anterior, 12 paramedian, 20 inferolateral vascular territory), and 37 non-stroke control patients matched for age and sex, we prospectively examined depression, anxiety, activities of daily living, and quality of life at 1, 6, 12, and 24 months post-stroke using the Hospital-Anxiety-and-Depression Scale (HADS), Nürnberger-Alters-Alltagsaktivitäten scale (NAA), and Short Form-36 (SF36) questionnaire. Voxel-based lesion-symptom mapping (VLSM) and lesion-subtraction analyzes were performed to determine associations between questionnaire scores and thalamic stroke topography.

Results

At 1 month post-stroke, anterior thalamic stroke patients had higher depression scores [8.0 (7.5; 10.5)] than paramedian [4.5 (1.0; 5.8)] and inferolateral [4.0 (1.0; 7.0)] thalamic stroke patients. Furthermore, anterior thalamic stroke patients had higher anxiety scores [11.0 (8.0; 14.5)] than their matched controls [2.5 (2.0; 2.5)], paramedian [4.5 (1.0; 5.8)] and inferior [4.0 (1.0; 7.0)] thalamic stroke patients. Depression and anxiety scores in anterior thalamic stroke patients remained high across the follow-up [depression: 9.0 (3.5; 13,8); anxiety:10.05 (2.8, 14.5)].Physical health assessed by SF36 was intact in anterior [1 month post-stroke: T-score = 55.9 (37.0; 57.6)] but reduced in inferolateral [44.5(32.4; 53.1)] thalamic stroke, whereas mental health was reduced in anterior thalamic stroke [32.0 (29.8; 47.3)].VLSM confirmed that voxels in the anterior thalamus around Montreal Neurological Institute (MNI) coordinates X = -8, Y = -12, Z = 2 were more often affected by the stroke in depressed (HADS-score ≥ 8) than non-depressed (HADS-score < 8) patients and voxels around coordinates X = -10, Y = -12, Z = 2 were more often affected in anxious (HADS-score ≥ 8) than non-anxious (HADS-score < 8) patients.

Conclusion

Anterior, but not paramedian or inferolateral thalamic stroke was associated with depression and anxiety. Even though our results are mostly significant in the left thalamus, this observation on stroke laterality might be confounded by the fact that the right hemisphere was underrepresented in our study.

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.

The role of the physical environment in stroke recovery: Evidence-based design principles from a mixed-methods multiple case study

Hospital design can impact patient outcomes, but there is very little healthcare design evidence specific to stroke rehabilitation facilities. Our aim was to explore, from the patient perspective, the role of the physical environment in factors crucial to stroke recovery, namely, stroke survivor activity (physical, cognitive, social), sleep, emotional well-being, and safety. We conducted a mixed-methods multiple-case study at two inpatient rehabilitation facilities in Victoria, Australia, (n = 20 at Case 1, n = 16 at Case 2) using "walk-through" semi-structured interviews, behavioural mapping, questionnaires, and retrospective audit. Four interrelated themes emerged: 1) entrapment and escape; 2) power, dependency, and identity in an institutional environment; 3) the rehabilitation facility is a shared space; and 4) the environment should be legible and patient-centred. Quantitative data revealed patterns in patient activity; stroke survivors spent over 75% of their time in bedrooms and were often inactive. Convergent mixed methods analysis was used to generate a new conceptual model of the role of the physical environment in stroke survivors' behaviour and well-being, highlighting the importance of variety and interest, privacy without isolation, and patient-centred design. This model can be used by designers, healthcare providers, and policy makers to inform the design of rehabilitation environments.

Predictive model, miRNA-TF network, related subgroup identification and drug prediction of ischemic stroke complicated with mental disorders based on genes related to gut microbiome

Background

Patients with comorbid schizophrenia, depression, drug use, and multiple psychiatric diagnoses have a greater risk of carotid revascularization following stroke. The gut microbiome (GM) plays a crucial role in the attack of mental illness and IS, which may become an index for the diagnosis of IS. A genomic study of the genetic commonalities between SC and IS, as well as its mediated pathways and immune infiltration, will be conducted to determine how schizophrenia contributes to the high prevalence of IS. According to our study, this could be an indicator of ischemic stroke development.

Methods

We selected two datasets of IS from the Gene Expression Omnibus (GEO), one for training and the other for the verification group. Five genes related to mental disorders and GM were extracted from Gene cards and other databases. Linear models for microarray data (Limma) analysis was utilized to identify differentially expressed genes (DEGs) and perform functional enrichment analysis. It was also used to conduct machine learning exercises such as random forest and regression to identify the best candidate for immune-related central genes. Protein-protein interaction (PPI) network and artificial neural network (ANN) were established for verification. The receiver operating characteristic (ROC) curve was drawn for the diagnosis of IS, and the diagnostic model was verified by qRT-PCR. Further immune cell infiltration analysis was performed to study the IS immune cell imbalance. We also performed consensus clustering (CC) to analyze the expression of candidate models under different subtypes. Finally, miRNA, transcription factors (TFs), and drugs related to candidate genes were collected through the Network analyst online platform.

Results

Through comprehensive analysis, a diagnostic prediction model with good effect was obtained. Both the training group (AUC 0.82, CI 0.93-0.71) and the verification group (AUC 0.81, CI 0.90-0.72) had a good phenotype in the qRT-PCR test. And in verification group 2 we validated between the two groups with and without carotid-related ischemic cerebrovascular events (AUC 0.87, CI 1-0.64). Furthermore, we investigated cytokines in both GSEA and immune infiltration and verified cytokine-related responses by flow cytometry, particularly IL-6, which played an important role in IS occurrence and progression. Therefore, we speculate that mental illness may affect the development of IS in B cells and IL-6 in T cells. MiRNA (hsa-mir-129-2-3p, has-mir-335-5p, and has-mir-16-5p) and TFs (CREB1, FOXL1), which may be related to IS, were obtained.

Conclusion

Through comprehensive analysis, a diagnostic prediction model with good effect was obtained. Both the training group (AUC 0.82, CI 0.93-0.71) and the verification group (AUC 0.81, CI 0.90-0.72) had a good phenotype in the qRT-PCR test. And in verification group 2 we validated between the two groups with and without carotid-related ischemic cerebrovascular events (AUC 0.87, CI 1-0.64). MiRNA (hsa-mir-129-2-3p, has-mir-335-5p, and has-mir-16-5p) and TFs (CREB1, FOXL1), which may be related to IS, were obtained.

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.

Psychedelic-Assisted Therapy and Psychedelic Science: A Review and Perspective on Opportunities in Neurosurgery and Neuro-Oncology

After a decades-long pause, psychedelics are again being intensely investigated for treating a wide range of neuropsychiatric ailments including depression, anxiety, addiction, post-traumatic stress disorder, anorexia, and chronic pain syndromes. The classic serotonergic psychedelics psilocybin and lysergic acid diethylamide and nonclassic psychedelics 3,4-methylenedioxymethamphetamine and ketamine are increasingly appreciated as neuroplastogens given their potential to fundamentally alter mood and behavior well beyond the time window of measurable exposure. Imaging studies with psychedelics are also helping advance our understanding of neural networks and connectomics. This resurgence in psychedelic science and psychedelic-assisted therapy has potential significance for the fields of neurosurgery and neuro-oncology and their diverse and challenging patients, many of whom continue to have mental health issues and poor quality of life despite receiving state-of-the-art care. In this study, we review recent and ongoing clinical trials, the set and setting model of psychedelic-assisted therapy, potential risks and adverse events, proposed mechanisms of action, and provide a perspective on how the safe and evidence-based use of psychedelics could potentially benefit many patients, including those with brain tumors, pain syndromes, ruminative disorders, stroke, SAH, TBI, and movement disorders. By leveraging psychedelics' neuroplastic potential to rehabilitate the mind and brain, novel treatments may be possible for many of these patient populations, in some instances working synergistically with current treatments and in some using subpsychedelic doses that do not require mind-altering effects for efficacy. This review aims to encourage broader multidisciplinary collaboration across the neurosciences to explore and help realize the transdiagnostic healing potential of psychedelics.

Esketamine ameliorates post-stroke anxiety by modulating microglial HDAC3/NF-κB/COX1 inflammatory signaling in ischemic cortex

Post-stroke anxiety (PSA) is a kind of affective disorder occurring after a stroke, with anxiety as the primary clinical manifestation. PSA's mechanism is unclear, and there are few prevention and treatment measures. Our previous study found that HDAC3 could activate NF-κB signaling through mediated p65 deacetylation, which further influenced microglia activation. That implies HDAC3 may be the key mediator in ischemic stroke mice and modulates anxiety susceptibility to stress. This study established a PSA model in male C57BL/6 mice through photothrombotic stroke combined with chronic restrain stress. We focused on exploring whether esketamine administration can alleviate anxiety-like behavior and neuroinflammation, which may be associated with inhibiting HDAC3 expression and NF-κB pathway activation. The results showed that esketamine administration alleviated anxiety-like behavior in PSA mice. And the results showed that esketamine alleviated cortical microglial activation, altered microglial number, and kept morphology features. Furthermore, the results showed that the expression of HDAC3, phosphor-p65/p65, and COX1 significantly decreased in esketamine-treated PSA mice. Besides, we also found that esketamine reduced PGE2 expression, one of the primary regulators of negative emotions. Interestingly, our results indicate that esketamine reduced the perineuronal net (PNN) number in the pathological process of PSA. In conclusion, this study suggests esketamine could alleviate microglial activation, reduces inflammatory cytokine, and inhibits the expression of HDAC3 and NF-κB in the cortex of PSA mice to attenuate anxiety-like behavior. Our results provided a new potential therapeutic target for applying esketamine to PSA.

Modeling the acceptability of BCIs for motor rehabilitation after stroke: A large scale study on the general public

Introduction

Strokes leave around 40% of survivors dependent in their activities of daily living, notably due to severe motor disabilities. Brain-computer interfaces (BCIs) have been shown to be efficiency for improving motor recovery after stroke, but this efficiency is still far from the level required to achieve the clinical breakthrough expected by both clinicians and patients. While technical levers of improvement have been identified (e.g., sensors and signal processing), fully optimized BCIs are pointless if patients and clinicians cannot or do not want to use them. We hypothesize that improving BCI acceptability will reduce patients' anxiety levels, while increasing their motivation and engagement in the procedure, thereby favoring learning, ultimately, and motor recovery. In other terms, acceptability could be used as a lever to improve BCI efficiency. Yet, studies on BCI based on acceptability/acceptance literature are missing. Thus, our goal was to model BCI acceptability in the context of motor rehabilitation after stroke, and to identify its determinants.

Methods

The main outcomes of this paper are the following: i) we designed the first model of acceptability of BCIs for motor rehabilitation after stroke, ii) we created a questionnaire to assess acceptability based on that model and distributed it on a sample representative of the general public in France (N = 753, this high response rate strengthens the reliability of our results), iii) we validated the structure of this model and iv) quantified the impact of the different factors on this population.

Results

Results show that BCIs are associated with high levels of acceptability in the context of motor rehabilitation after stroke and that the intention to use them in that context is mainly driven by the perceived usefulness of the system. In addition, providing people with clear information regarding BCI functioning and scientific relevance had a positive influence on acceptability factors and behavioral intention.

Discussion

With this paper we propose a basis (model) and a methodology that could be adapted in the future in order to study and compare the results obtained with: i) different stakeholders, i.e., patients and caregivers; ii) different populations of different cultures around the world; and iii) different targets, i.e., other clinical and non-clinical BCI applications.

Factors associated with mental health service access among Australian community-dwelling survivors of stroke

PURPOSE

To describe types of mental health treatment accessed by community-based stroke survivors and factors associated with access.

METHODS

A sub-group of registrants from the Australian Stroke Clinical Registry completed a supplementary survey 2.5 years post-stroke. Self-reported information about depression/anxiety and treatment access were collected. Demographic and clinical data were obtained through linkages with registry and government data. Staged multivariable logistic regression was conducted to examine factors associated with treatment access.

RESULTS

Among 623 registrants surveyed (37% female, median age 69 years), 26% self-reported a medical diagnosis of depression/anxiety at 2.5 years post-stroke. Of these, only 30% reported having accessed mental health services, mostly through government-funded Medicare schemes. Younger age (odds ratio (OR) 0.95, 95% CI 0.93, 0.98), history of mental health treatment (OR 3.38, 95% CI 1.35, 8.48), feeling socially isolated (OR 2.32, 95% CI 1.16, 4.66), self-reported medical diagnosis of depression/anxiety (OR 4.85, 95% CI 2.32, 10.14), and government-subsidised team care plan arrangement (OR 4.05, 95% CI 1.96, 8.37) were associated with receiving treatment.

CONCLUSIONS

Many stroke survivors have untreated depression/anxiety. Primary care practitioners should be supported in undertaking effective detection and management. Older and newly diagnosed individuals should be educated about depression/anxiety and available supports.Implications for rehabilitationPrimary care providers play a pivotal role in the pathway to mental health care, and therefore should always screen for depression/anxiety and provide comprehensive assessment and referral to specialist services where necessary.Targeted psychoeducation should be provided to survivors of stroke who are older and newly diagnosed with depression/anxiety, to increase awareness about mood problems following stroke.Primary care providers should collaborate with other health professionals (e.g., through coordinating a team care arrangement plan), to address patients' multiple and complex rehabilitation needs.Rehabilitation professionals should remain informed about current evidence-based treatments for post-stroke depression/anxiety and pathways that enable their patients to access these services.

Psychological distress in pulmonary embolism survivors in a pulmonary embolism response team clinic: Protocol for a prospective observational study

Background

Pulmonary embolism (PE) is a leading cause of cardiovascular death. Psychological distress in PE is understudied and underrecognized.

Objectives

The primary aim of this proposed protocol was to describe the incidence of psychological distress symptoms (anxiety, depression, posttraumatic stress, and fear of recurrence) in the survivors of PE after discharge from hospitalization. The secondary aim was to assess the influence of acute disease, etiology, and treatment of PE on psychological distress.

Methods

This is a prospective observational cohort study in a large tertiary care referral center. The participants are adult patients presenting to the hospital with PE fulfilling objective pulmonary embolism response team (PERT) activation criteria. After discharge, patients complete a series of validated measures of psychological distress (anxiety, depression, posttraumatic stress, and fear of recurrence) and quality of life at follow-ups approximately 1, 3, 6, and 12 months after diagnosis and treatment of their PE. Factors influencing each type of distress are evaluated.

Conclusion

This protocol aims to identify the unmet needs of patients experiencing psychological distress following PE. It will describe anxiety, depression, fear of recurrence, and posttraumatic symptoms in PE survivors during the first year of outpatient follow-up in a PERT clinic.

B-vitamin supplementation on mitigating post-stroke cognition and neuropsychiatric sequelae: A randomized controlled trial

BACKGROUND AND PURPOSE

A third of stroke patients suffer from post-stroke cognitive decline, depressive symptoms, and anxiety symptoms. B-vitamin supplementation provides a possible safe and affordable treatment to mitigate post-stroke neuropsychiatric sequelae via reducing homocysteine levels. Our study aims to examine the effect of B-vitamin supplementation in the prevention of post-stroke cognitive decline, depressive symptoms, and anxiety symptoms. Our secondary aims were to investigate associations between baseline factors and the three outcomes.

METHODS

Patients were recruited as part of a Singaporean substudy of a randomized controlled trial that examined the effect of B-vitamin supplementation on recurrent cardiovascular events. Cognitive decline, depressive symptoms, and anxiety symptoms were assessed with neuropsychological assessments and Hospital Anxiety and Depression Scale 6 monthly. Cox regression analyses were performed to determine treatment efficacy. Logistic regression used to examine factors associated with cognitive decline, depressive symptoms, and anxiety symptoms.

RESULTS

A total of 707 were included in the analyses. Survival and hazards ratio analysis showed no treatment effect of B-vitamins on cognitive decline, depressive symptoms, and anxiety symptoms. Cognitive decline was only associated with age. Depressive symptoms were associated with large anterior cerebral infarcts and hyperlipidemia.

CONCLUSIONS

Our study showed no benefit of supplementation with B-vitamins for post-stroke cognitive decline, depressive symptoms, or anxiety symptoms. Depressive symptoms were associated with larger anterior cerebral infarcts, which may be reflective of the disability associated with larger infarcts.

"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.

Palliative care after stroke survival

Stroke is a leading cause of both death and disability worldwide. While most research has focused on the first hours to days after acute stroke, much less is known about the experience of patients and their families living after a stroke. Stroke survivors have a high burden of physical and psychological symptoms such as pain, fatigue, and depression that are often not addressed in the postacute setting. Similarly, goals-of-care conversations that may have started during the acute hospitalization are often not followed up later. This chapter outlines the prevalence and management of common poststroke symptoms, approaches to postacute goals-of-care conversations, family needs after stroke, and provides an overview of stroke-specific hospice and end-of-life care aspects. We emphasize the need for research in each of these areas.

The efficacy of therapist-supported acceptance and commitment therapy-based bibliotherapy for psychological distress after stroke: a single-case multiple-baseline study

BACKGROUND

Psychological distress is common after stroke, and affects recovery. However, there are few evidence-based psychological treatments. This study evaluates a bibliotherapy-based approach to its amelioration.

AIMS

To investigate a stroke-specific self-management book, based on acceptance and commitment therapy (ACT), as a therapist-supported intervention for psychological distress after stroke.

METHOD

The design was a single case, randomised non-concurrent multiple-baseline design (MBD). Sixteen stroke survivors, eight males and eight females (mean age 60.6 years), participated in an MBD with three phases: A (randomised-duration baseline); B (intervention); and follow-up (at 3 weeks). During the baseline, participants received therapist contact only. In the bibliotherapy intervention, participants received bi-weekly therapist support. The primary measures of psychological distress (General Health Questionaire-12; GHQ-12) and quality of life (Satisfaction with Life Scale; SWLS) were completed weekly. Secondary measures of mood, wellbeing and illness impact were completed pre- and post-intervention.

RESULTS

Omnibus whole-group TAU-U analysis was statistically significant for each primary measure with a moderate effect size on both (0.6 and 0.3 for GHQ-12 and SWLS, respectively). Individual TAU-U analyses demonstrated that the majority of individuals exhibited positive change. All the secondary measures showed significant pre-post improvements. Eighty-one per cent of participants reported the book was helpful and 81% also found the ACT-based sections helpful. Relative risk calculations showed finding the book helpful was associated with improvement in GHQ-12 and SWLS scores.

CONCLUSIONS

ACT-based bibliotherapy, with therapist support, is a promising intervention for psychological difficulties after stroke.

Relationships of Low Serum Levels of Interleukin-10 With Poststroke Anxiety and Cognitive Impairment in Patients With Clinical Acute Stroke

BACKGROUND AND PURPOSE

The relationships among interleukin (IL)-10 levels, anxiety, and cognitive status after stroke remain controversial. We aimed to determine the associations of serum IL-10 levels with poststroke anxiety (PSA) and poststroke cognitive impairment (PSCI).

METHODS

We recruited 350 patients with stroke, of whom only 151 completed a 1-month follow-up assessment. The Mini Mental State Examination (MMSE) and Hamilton Anxiety Scale (HAMA) were used to assess the cognitive status and anxiety, respectively. Serum IL-10 levels were measured within 24 hours of admission.

RESULTS

IL-10 levels were significantly lower in the PSA group than in the non-PSA group, and they were negatively associated with HAMA scores (r=-0.371, p<0.001). After adjusting for all potential confounders, IL-10 levels remained an independent predictor of PSA (odds ratio=0.471, 95% confidence interval=0.237-0.936, p=0.032). IL-10 levels were strongly correlated with behavior during interviews, psychic anxiety, and somatic anxiety. Patients without PSCI had higher IL-10 levels were higher in non-PSCI patients than in PSCI patients, and they were positively associated with MMSE scores in the bivariate correlation analysis (r=0.169, p=0.038), and also with memory capacity, naming ability, and copying capacity. However, IL-10 did not predict PSCI in the univariable or multivariable logistic regression.

CONCLUSIONS

Low IL-10 levels were associated with increased risks of PSA and PSCI at a 1-month follow-up after stroke. Serum IL-10 levels may therefore be helpful in predicting PSA.

Palliative care approaches to acute stroke in the hospital setting

Stroke is a prevalent neurologic condition that portends a high risk of morbidity and mortality such that patients impacted by stroke and their caregivers can benefit from palliative care at the time of diagnosis and throughout the disease trajectory. Clinicians who care for stroke patients should be adept at establishing rapport with patients and caregivers, delivering serious news, responding to emotions, discussing prognosis, and establishing goals of care efficiently in an acute stroke setting. Aggressive stroke care can be integrated with a palliative approach to care that involves aligning the available treatment options with a patient's values and goals of care. Reassessing the goals throughout the hospitalization provides an opportunity for continued shared decision-making about the intensity of poststroke interventions. The palliative needs for stroke patients may increase over time depending on the severity of disease, poststroke complications, stroke-related symptoms, and treatment intensity preferences. If the decision is made to transition the focus of care to comfort, the support of an interdisciplinary palliative care or hospice team can be beneficial to the patient, family members, and surrogate decision makers.

The Associated Factors of Quality of Life among Stroke Survivors: A Study in Indonesia

Background: The prevalence and burden of stroke are still high, especially in low and middle-income countries. Stroke affects the economy and physics related to the Quality of Life (QoL). Various QoL-associated factors, including sociodemographic, functional outcome, emotional, and cognitive function, were studied. However, there was very limited information about the QoL-associated factors among stroke survivors in Semarang, Indonesia.Purpose: This study aimed to identify the QoL-associated factors among stroke survivors in Semarang, Indonesia.Methods: This cross-sectional study was conducted in outpatient services and involved 57 ischemic stroke survivors using convenience sampling. Demographic and clinical information were obtained using medical records and questionnaires. The questionnaires were the Short Version of Specific Stroke Quality of Life (SS-QoL) to measure QoL, GRID-HAMD 17 to measure Post Stroke Depression (PSD), Mini-Mental Status Examination (MMSE) to measure cognitive impairment, Barthel–Index (BI) to measure functional outcome, Hamilton Anxiety Rating Scale (HAM-A) to measure anxiety, and Multidimensional Scale of Perceived Social Support (MSPSS) to measure social support. Linear regression was conducted in the model performance of QoL-associated factors.Results: The stroke duration was 155(18) days, and 50.9% of participants were males. The linear regression showed that age (-.164 95% CI -.412 - .084), marital status (3.937 95% CI 1.010 - 6.864), functional outcome (.127 95% CI .013 - .241), PSD (-1.090 95% CI -2.144 - -.036), cognitive function (.308 95% CI -.482 - 1.098) and anxiety (-.408 95% CI -1.125 - .268) were QoL-predictors (p<.001, adjusted R2=52.1). It is assumed that age, marital status, functional outcome, PSD, cognition, and anxiety significantly predict the QoL among ischemic stroke survivors.Conclusion: The QoL-associated factors were age, marital status, functional outcome, PSD, cognition, and anxiety. These associated factors of QoL should be considered as elements in formulating nursing interventions that aim to improve the good QoL among stroke survivors.

Added value of patient-reported outcome measures (PROMs) after an acute stroke and early predictors of 90 days PROMs

Introduction

Value-based health care represents a patient-centered approach by valuing Patient-Reported Outcome Measures (PROMs). Our aim was to describe the additional value of PROMs after an acute stroke over conventional outcome measures and to identify early predictors of poor PROMs.

Methods

Acute stroke patients discharged from a tertiary care hospital followed by a web/phone-based PROMs collection program in the post hospitalization phase. Main PROMs involve anxiety and depression (HADS) (each defined by HADS ≥ 10) and global physical (PHY-) and mental (M-) health (PROMIS-10). PROMIS cut-off raw values of normality were: PHY-PROMIS ≥ 13 and M-PROMIS ≥ 11. An overall health status (OHS) from 0 to 100 was also determined. PROMs related to the different modified Rankin Scale (mRS) grades were defined. Early predictors of PROMs were evaluated.

Results

We included 1321 stroke patients, mean age 75 (± 8.6) and 55.7% male; 77.7% returned home. Despite a favorable mRS at 3 months (< 3), a relevant rate of patients considered without symptoms or with mild disability showed unfavorable results in the measured PROMs (8% unfavorable OHS, 15% HAD-depression, 12.1% HAD-anxiety, 28.7% unfavorable M-PROMIS and 33.1% unfavorable PHY-PROMIS results). Along follow-up, only PHY-PROMIS and OHS showed significant improvement (p < 0.01 and 0.03, respectively). The multivariate analysis including discharge variables showed that female sex, higher discharge mRS and discharge to socio-rehabilitation-center (SRC) were independent predictors of unfavorable results in PROMs (p < 0.01). When adding 7 days PROMs results, they emerged as the strongest predictors of 3 months PROMs.

Conclusions

A high proportion of stroke patients show unfavorable results in PROMs at 3 months, even those with favorable mRS, and most results obtained by PROMs during follow-up continued to indicate alterations. Female sex, mRS and discharge to SRC predicted unfavorable results in PROMs, but the strongest predictors of 3 months PROMs were the results of the 7 days PROMs.

A Scoping Review on the Effects of Emotional Stimuli on Language Processing in People With Aphasia

PURPOSE

Emotional stimuli have been shown to influence language processing (both language comprehension and production) in people with aphasia (PWA); however, this finding is not universally reported. Effects of emotional stimuli on language performance in PWA could have clinical and theoretical implications, yet the sparsity of studies and variability among them make it difficult to appraise the significance of this effect. The purpose of this scoping review was to (a) determine the extent and range of research examining the effect of emotional stimuli on language processing in PWA, (b) summarize and evaluate research findings, and (c) identify gaps in the literature that may warrant future study.

METHOD

PsycINFO, PubMed, Web of Science, and Cumulative Index to Nursing and Allied Health Literature databases were systematically searched for articles that compared performance in response to emotional and nonemotional stimuli on at least one language measure in one or more adults with aphasia. Data related to methods and results were extracted from each article and charted in Excel.

RESULTS

Five hundred forty unique articles were found, and 18 articles, consisting of 19 studies, met inclusion/exclusion criteria for this review. Of the 19 studies included, 11 studies reported enhanced performance on a language task for emotional compared to nonemotional stimuli, seven reported no difference, and one reported worse performance for emotional compared to nonemotional stimuli. Possible modulating variables such as task type, measurement, stimulus characteristics, and sample characteristics are discussed along with gaps in the literature.

CONCLUSION

The extent of research in this area is sparse; however, there does appear to be some early evidence for better performance in response to emotional over nonemotional stimuli in PWA for some, but not all, language processes investigated.

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.

Effects of dry needling intervention on lower limb dysfunction after stroke: study protocol for a randomised controlled trial

INTRODUCTION

Lower limb dysfunction is among the common sequelae of patients who had a poststroke and often results in the reduction of the quality of life. This study aims to assess the short and interim-term efficacy of dry needling (DN) intervention on lower extremity function, balance and gait in lower limb dysfunction after stroke.

METHODS AND ANALYSIS

This protocol entails an assessor and statistician-blinded, single-centre study with a randomised controlled trial. Forty-four patients who had a poststroke will be randomly allocated (1:1) to either the conventional treatment group (n=22) or the DN group (n=22). The conventional treatment group will receive conventional rehabilitation treatment once a day for 40 min each time. The treatment will be performed five times a week for 2 weeks. In the DN group, participants will be treated with DN on the basis of the conventional treatment. The intervention will be performed thrice a week for 2 weeks. The primary outcome that determines the efficacy of lower limb dysfunction will be the change in the Fugl-Meyer Assessment of Lower Extremity scale. The secondary indicators include the range of motion of knee and ankle joints, limits of stability, modified Clinical Test of Sensory Interaction on Balance, Timed Up and Go test, Modified Ashworth Scale and Barthel Index. Results will be evaluated at baseline, at 24 hours after intervention, at 2 weeks after intervention and at 3-month follow-up. Data will be released after the completion of the study.

Disruption of Sonic Hedgehog Signaling Accelerates Age-Related Neurogenesis Decline and Abolishes Stroke-Induced Neurogenesis and Leads to Increased Anxiety Behavior in Stroke Mice

Sonic Hedgehog (SHH) signaling has a critical role in mediating developmental neurogenesis and has been implicated in adult subventricular (SVZ) neurogenesis. However, the precise role of Smoothened (SMO) receptor-mediated SHH signaling in adult neurogenesis during aging especially in hippocampal subgranular zone (SGZ) neurogenesis remains undefined. Additionally, our previous study showed that stimulation of SHH signaling post-stroke leads to increased neurogenesis and improved behavioral functions after stroke. However, it is not clear whether SHH signaling in neural stem cells (NSCs) is required for stroke-induced neurogenesis and functional recovery post-stroke. In this study, using conditional knockout (cKO) of SHH signaling receptor Smo gene in NSCs, we show a decreased neurogenesis at both SVZ and SGZ in young-adult mice and an accelerated depletion of neurogenic cells in the process of aging suggesting that SHH signaling is critical in maintaining neurogenesis during aging. Behavior studies revealed that compromised neurogenesis in Smo cKO mice leads to increased anxiety/depression-like behaviors without affecting general locomotor function or spatial and fear-related learning. Importantly, we also show that NSCs with a cKO of SHH signaling abolishes stroke-induced neurogenesis in Smo cKO mice. Compared to control mice, Smo cKO mice also show delayed motor function recovery and increased anxiety level after stroke. Our data highlights the essential role of Smo function in regulating adult neurogenesis and emotional behaviors during both aging and CNS injury such as stroke.

The efficacy and safety of Jin's three-needle therapy vs. placebo acupuncture on anxiety symptoms in patients with post-stroke anxiety: A study protocol for a randomized controlled trial

Background

A large number of clinical RCTs have verified that Jin's three-needle therapy (JTNT) has a great contribution to promoting the function of paralyzed limbs and relieving anxiety disorders for patients with post-stroke anxiety (PSA). However, there is still a lack of sham needle control, and its placebo effect cannot be ruled out. This study firstly verifies the real effectiveness of JTNT. Besides, the changes in serum indexes on the hypothalamic-pituitary-adrenal axis (HPA axis) are observed dynamically by the Enzyme-Linked ImmunoSorbent Assay (ELISA). The activation of different brain regions by JTNT is recorded using resting functional magnetic resonance imaging (rs-fMRI). Therefore, we can provide more practical and powerful evidence-based medical evidence for clinical decisions.

Method

This is a 16 week parallel, single-blind, random, controlled trial, including baseline, 4 weeks of treatment, and 12 weeks of follow-up. A total of 114 participants will be randomly divided into three groups in the proportion of 1:1:1. Participants will receive Jin's three-needle therapy in the active acupuncture group and accept sham needle treatment in the sham acupuncture group. In the waitlist control group, patients will not receive any acupuncture treatment. Outcomes cover three types of indicators, including scale indicators, serum indicators, and imaging indicators. The primary outcome is the change in the performance of anxiety symptoms, which is estimated by the 14-item Hamilton Anxiety Rating Scale (HAMA-14) and the 7-item Generalized Anxiety Disorder scale (GAD-7). Secondary outcomes are physical recovery and daily quality of life, which are evaluated by the National Institute of Health stroke scale (NIHSS) and the Modified Barthel Index Score (MBI Scale). Therefore, the assessment of the scale is carried out at baseline, 2nd, 4th, 8, 12, and 16 weeks. Adrenocorticotropin and cortisol will be quantitatively detected by ELISA at baseline and 4 weeks after treatment. In addition, regional homogeneity analysis (ReHo) will be used to record the activity of brain regions at baseline and 4 weeks after intervention.

Discussion

The study aims to provide high-quality clinical evidence on the effectiveness and safety of JTNT for patients with PSA. In addition, this trial explores a possible mechanism of JTNT for patients with PSA.

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.

Mindfulness and Relaxation Techniques for Stroke Survivors with Aphasia: A Feasibility and Acceptability Study

Stroke survivors with aphasia (SsWA) tend to experience high levels of anxiety and stress, leading to an increased risk of recurrent strokes. Mindfulness and/or relaxation that does not require language outputs could reduce psychosocial stress; however, these approaches work best if they consist of a range of techniques and are modified to suit the needs of SsWA. Using a mixed-methods approach, we examined the feasibility and acceptability of a set of tailored mindfulness and relaxation techniques for SsWA. Nine SsWA were recruited (six men and three women, median age = 51 years). Four relaxation and mindfulness techniques which had been tailored for SsWA were filmed into a DVD/YouTube video and were given to participants together with a practice diary for home practice once daily for 5 weeks. The participants joined focus group discussions and completed a feasibility scale 5 weeks later. The participants perceived these techniques as easy, user-friendly and acceptable for SsWA in general. Although practised less often than instructed, many participants reported benefits of regular practice. The perceived relevance of these techniques to the participants' own situations and the intention to continue varied. Future research could encourage the regular practice of self-help interventions by incorporating behavioural change techniques such as using prompts and cues.

The role of enriched environment in neural development and repair

In addition to genetic information, environmental factors play an important role in the structure and function of nervous system and the occurrence and development of some nervous system diseases. Enriched environment (EE) can not only promote normal neural development through enhancing neuroplasticity but also play a nerve repair role in restoring functional activities during CNS injury by morphological and cellular and molecular adaptations in the brain. Different stages of development after birth respond to the environment to varying degrees. Therefore, we systematically review the pro-developmental and anti-stress value of EE during pregnancy, pre-weaning, and “adolescence” and analyze the difference in the effects of EE and its sub-components, especially with physical exercise. In our exploration of potential mechanisms that promote neurodevelopment, we have found that not all sub-components exert maximum value throughout the developmental phase, such as animals that do not respond to physical activity before weaning, and that EE is not superior to its sub-components in all respects. EE affects the developing and adult brain, resulting in some neuroplastic changes in the microscopic and macroscopic anatomy, finally contributing to enhanced learning and memory capacity. These positive promoting influences are particularly prominent regarding neural repair after neurobiological disorders. Taking cerebral ischemia as an example, we analyzed the molecular mediators of EE promoting repair from various dimensions. We found that EE does not always lead to positive effects on nerve repair, such as infarct size. In view of the classic issues such as standardization and relativity of EE have been thoroughly discussed, we finally focus on analyzing the essentiality of the time window of EE action and clinical translation in order to devote to the future research direction of EE and rapid and reasonable clinical application.

Stroke epidemiology in southern Brazil: Investigating the relationship between stroke severity, hospitalization costs, and health-related quality of life

We aimed with the present study to fill the gap on the performance and safety of stroke management and the costs related to hospitalizations, the relevant comorbidities associated with stroke patients, and the stroke patient outcomes health-related quality of life (HRQOL) progress. Our study investigated the clinical, neurological, and social impact of stroke in 220 patients in a tertiary hospital located in the countryside of the state of Santa Catarina, Brazil. Description of clinical and neurological characteristics of stroke patients between 2015 to 2020 was analyzed using electronic medical records. The most affected age group was 61-80 years, being female the most affected sex. Almost 89.5% of the patients had some risk factor, with a higher prevalence of ischemic stroke. This type of stroke was the expensive, in terms of hospitalization, with an average cost of $74.10. Considering the stroke-specific quality of life scale (SSQOL) score, 88.3% of patients who demonstrated some comorbidity and 47.6% of women had lower quality of life levels post-stroke. Our data could be useful to substantiate a data-base with epidemiology statistics characterization of stroke hospitalizations, indicating the severity of stroke for the patient.

Development of the "Kalmer" relaxation intervention: co-design with stroke survivors with aphasia

PURPOSE

Anxiety is common after stroke and more prevalent in survivors with aphasia. Relaxation is an effective first-line therapy. The current study aimed to obtain the perspectives of stroke survivors with aphasia to inform the development of an accessible, technology-based, relaxation intervention.

MATERIALS AND METHODS

Qualitative co-design methods were used with twelve people with aphasia after stroke. The "Kalmer" Relaxation treatment package materials were iteratively based on participants' experiences and preferences; barriers and facilitators to treatment compliance were explored. Participants were also asked to consider how the intervention might be evaluated in a research trial.

RESULTS

A thematic analysis highlighted the importance and need for the development of an appropriate and inclusive relaxation product, to be implemented by health professionals early post-stroke. Several behavioural strategies to improve treatment adherence were recommended. Participants had varying perspectives on clinically meaningful treatment outcomes.

CONCLUSIONS

Overall, a co-designed accessible relaxation product was viewed as a necessary component of usual stroke care. Acceptability and feasibility and preliminary efficacy of the "Kalmer" intervention should be trialled in future studies. IMPLICATIONS FOR REHABILITATIONCo-designing psychological interventions for people with aphasia after stroke is needed to meet the needs of this at-risk population.Technology-based relaxation interventions to manage anxiety after stroke are viewed positively by people with aphasia and deemed acceptable and feasible.Clinical trials of these co-designed relaxation interventions are required before recommending integration into routine practice.
