Association Between Anxiety, Depression, and Post-traumatic Stress Disorder and Outcomes After Ischemic Stroke

Non-pharmacological interventions on quality of life in stroke survivors: A systematic review and meta-analysis

BACKGROUND

Non-pharmacological interventions have been used in the rehabilitation of stroke survivors, but their effects on stroke survivors' quality of life (QoL) are unknown.

AIM

This review aimed to summarize the existing evidence regarding non-pharmacological interventions for QoL in stroke survivors and to evaluate the effectiveness of different types of interventions.

METHODS

We systematically searched databases including PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese BioMedical Literature Database, China Science and Technology Journal Database, and Wanfang data from the earliest available records to March 2023. Randomized controlled trials which explored the effects of non-pharmacological interventions on QoL in stroke patients were included. The meta-analysis was conducted to evaluate the effectiveness of different interventions on QoL. The Review Manager 5.3 was used to conduct the meta-analysis and the revised Cochrane risk-of-bias tool was used to assess the methodological quality of trials.

RESULTS

A total of 93,245 records were identified, and 34 articles were reviewed and summarized, of which 20 articles were included in the meta-analysis. The summary of the findings of the included studies revealed fitness training, constraint-induced movement therapy (CIMT), physical exercise, music therapy (MT), and art-based interventions may have positive effects on QoL. The fitness training improved total QoL, especially in physical domains including physical functioning (mean difference [MD] = 10.90; 95% CI [7.20, 14.59]), role physical (MD = 10.63; 95% CI [6.71, 14.55]), and global health (MD = 8.76; 95% CI [5.14, 12.38]). The CIMT had a slight effect on general QoL (standardized mean difference [SMD] = 0.48, 95% CI [0.16, 0.80]), whereas significantly improved strength (MD = 8.84; 95% CI [1.31, 16.38]), activities of daily living/instrumental activities of daily living (ADL/IADL; MD = 10.42; 95% CI [2.98, 17.87]), and mobility (MD = 8.02; 95% CI [1.21, 14.83]). MT had a positive effect on the mental health domain (SMD = 0.54; 95% CI [0.14, 0.94]).

LINKING EVIDENCE TO ACTION

Our findings suggest that fitness training and CIMT have a significant effect on improving physical QoL, while MT has a positive effect on improving psychological QoL. Future studies may use comprehensive and multicomponent interventions to simultaneously improve the patients' physical, psychological, and social QoL.

Association of Posttraumatic Stress Disorder and Race on Readmissions After Stroke

BACKGROUND

There is limited research on outcomes of patients with posttraumatic stress disorder (PTSD) who also develop stroke, particularly regarding racial disparities. Our goal was to determine whether PTSD is associated with the risk of hospital readmission after stroke and whether racial disparities existed.

METHODS

The analytical sample consisted of all veterans receiving care in the Veterans Health Administration who were identified as having a new stroke requiring inpatient admission based on the International Classification of Diseases codes. PTSD and comorbidities were identified using the International Classification of Diseases codes and given the date of first occurrence. The retrospective cohort data were obtained from the Veterans Affairs Corporate Data Warehouse. The main outcome was any readmission to Veterans Health Administration with a stroke diagnosis. The hypothesis that PTSD is associated with readmission after stroke was tested using Cox regression adjusted for patient characteristics including age, sex, race, PTSD, smoking status, alcohol use, and comorbidities treated as time-varying covariates.

RESULTS

Our final cohort consisted of 93 651 patients with inpatient stroke diagnosis and no prior Veterans Health Administration codes for stroke starting from 1999 with follow-up through August 6, 2022. Of these patients, 12 916 (13.8%) had comorbid PTSD. Of the final cohort, 16 896 patients (18.0%) with stroke were readmitted. Our fully adjusted model for readmission found an interaction between African American veterans and PTSD with a hazard ratio of 1.09 ([95% CI, 1.00-1.20] P=0.047). In stratified models, PTSD has a significant hazard ratio of 1.10 ([95% CI, 1.02-1.18] P=0.01) for African American but not White veterans (1.05 [95% CI, 0.99-1.11]; P=0.10).

CONCLUSIONS

Among African American veterans who experienced stroke, preexisting PTSD was associated with increased risk of readmission, which was not significant among White veterans. This study highlights the need to focus on high-risk groups to reduce readmissions after stroke.

The Flow State Scale for Rehabilitation Tasks: A New Flow Experience Questionnaire for Stroke Patients

IMPORTANCE

Flow can be described as a subjective state that people report when they fully engage in an activity and experience pleasure, satisfaction, and enjoyment. Flow experiences are measured to determine the extent to which patients engage in therapy activities. Several flow questionnaires are used in neurorehabilitation. However, none have been validated for patients with (sub)acute stroke.

OBJECTIVE

To develop and validate a new flow questionnaire for patients with (sub)acute stroke.

DESIGN

Single-center prospective cohort study.

SETTING

Neurorehabilitation unit of the Neurocenter of the Luzerner Kantonsspital in Lucerne, Switzerland.

PARTICIPANTS

Fifty patients with (sub)acute stroke.

OUTCOMES AND MEASURES

Development of the Flow State Scale for Rehabilitation Tasks (FSSRT) and determination of the psychometric properties of the FSSRT (internal consistency, test-retest reliability, structural and construct validity) in (sub)acute stroke patients.

RESULTS

The FSSRT showed good internal consistency and excellent test-retest reliability. Composed of four components-concentration, pleasure, movement control, and absorption-the FSSRT correlated significantly negatively with the Hospital Anxiety and Depression Scale, indicating good divergent validity.

CONCLUSIONS AND RELEVANCE

The FSSRT is a reliable and valid questionnaire measuring flow experience in patients with (sub)acute stroke. This questionnaire can be easily used in occupational therapy as well as in physical therapy and gives therapists important information about the flow experience of patients during therapy to adjust the therapy accordingly. Plain-Language Summary: Measuring flow experience, or the extent to which patients engage in therapy activities, in the context of occupational therapy and physical therapy is a new approach. This study confirmed that the Flow State Scale for Rehabilitation Tasks questionnaire is reliable and valid for measuring the flow experience of patients after (sub)acute stroke. Occupational therapists and physical therapists can use the FSSRT to optimally adjust the therapy program and increase patient engagement during therapy.

Psychotic Disorder after Left Posterior Cerebral Artery Stroke-An Atypical Event

INTRODUCTION

Stroke survivors usually present physical and neuropsychiatric complications. Post-stroke psychosis (PSPsy) is a particularly neglected sequel despite its disruptive nature.

OBJECTIVES

To present a case of early emerging neuropsychiatric symptoms following a left posterior cerebral artery (PCA) stroke. To review and discuss PSPsy clinical manifestations, pathophysiology, and clinical outcomes.

CLINICAL CASE

A previously autonomous 68-year-old woman with vascular risk factors and depressive disorder presented to the emergency department with a 5-day history of disorientation, motor aphasia, and right hypoesthesia. Computer tomography revealed a left PCA stroke. She was started on acetylsalicylic acid and rosuvastatin and discharged the next day. Afterward, the patient developed a depressive mood, emotional lability, periods of confusion, delusions of persecution, guilt and unworthiness, auditory hallucinations, and suicide ideation. She was admitted to a psychiatric hospital and started on risperidone with a good response, being discharged after 15 days with the resolution of psychiatric symptoms.

CONCLUSIONS

PSPsy is more common after right hemisphere lesions and usually develops after some months. Nevertheless, our patient presented PSPsy following an ischemic event of the left PCA, with neuropsychiatric symptomatology dominating the clinic since the beginning. The involvement of the retrosplenial cortex or its connections was likely important for this atypical presentation. Due to the lack of guidelines on approaching PSPsy, most patients are treated with the same strategies used for non-stroke patients. A better comprehension of the anatomical basis underlining the symptomatology in these patients could deepen the understanding of psychosis and psychotic disorders.

Is sleep quality a moderated mediator between perceived stress and depression among stroke patients?

Background

Sleep quality can offer new insights into addressing depression among stroke patients. However, the current understanding of the mechanism by which sleep quality reduces depression is not clear in existing research.

Objectives

This study aimed to identify the relationships and mechanisms among perceived stress, sleep quality, social support, and depression in stroke patients.

Methods

A multicenter cross-sectional study was conducted from January to May 2023. Cluster random sampling was used to recruit 500 stroke patients from five hospitals in Henan Province, China. The Chinese Perceived Stress Scale (CPSS), Pittsburgh Sleep Quality Index (PSQI), Social Support Rating Scale (SSRS), and Hamilton Depression Scale (HAMD-24) were employed to assess perceived stress, sleep quality, social support, and depression, respectively. Data were analyzed using descriptive analysis, Pearson's correlation analysis, and moderated mediation analysis. The study adhered to the STROBE checklist for reporting.

Results

Out of 500 participants, 471 completed the survey (94.2%). After controlling for sex and age, mediation analysis revealed that poor sleep quality partially mediated the relationship between perceived stress and depression (β = 0.184, 95% CI: 0.110, 0.359). Additionally, social support played a moderating role in the mediation model.

Conclusion

This study explained the moderated mediation of sleep quality and social support between perceived stress and depression. It provided a theoretical basis for the development of a sleep quality intervention program for reducing depression among stroke patients.

Morroniside improves the symptoms of post-stroke depression in mice through the BDNF signaling pathway mediated by MiR-409-3p

BACKGROUND

Post-stroke depression (PSD) is a common psychiatric symptom after a stroke. Morroniside, an iridoid glycoside found in Cornus officinalis, has garnered significant attention for its potential to alleviate symptoms associated with depression.

PURPOSE

This study aims to highlight the potential use of morroniside in the treatment of PSD and elucidate the underlying molecular mechanisms.

METHODS

To establish a reliable PSD model, male C57BL/6 mice were subjected to brief MCAO in conjunction with CUMS. Post-morroniside administration, neuronal viability, and hippocampal cell apoptosis were evaluated by Nissl staining and TUNEL detection, respectively. Depression-like behaviors were evaluated using SPT, TST, and FST. The Longa score and cylinder test were used to evaluate the effect of morroniside on motor function. Furthermore, to investigate the underlying molecular mechanisms, bioinformatic analysis and the dual luciferase assay were performed to investigate the MiR-409-3p-BDNF interaction. In addition, subsequent to MiR-409-3p overexpression via AAV virus, we assessed mRNA expression and protein levels of key components within the BDNF/TrkB signaling pathway using RT-qPCR, immunohistochemistry, and western blot analysis.

RESULTS

The observed decrease in apoptosis and amelioration of depression-like behaviors strongly indicate the potential of morroniside as a therapeutic agent for PSD. Furthermore, the upregulation of key proteins within the BDNF/TrkB signaling pathway in the cortex suggests that morroniside activates this pathway. Through bioinformatics analysis, MiR-409-3p was identified and found to bind to the BDNF gene, resulting in the inhibition of BDNF expression. Importantly, we demonstrate that morroniside mitigates this inhibitory effect of MiR-409-3p on BDNF, thereby facilitating the activation of the BDNF/TrkB signaling pathway.

CONCLUSION

The findings suggest that morroniside demonstrates the ability to improve PSD symptoms through the BDNF/TrkB signaling pathway mediated by MiR-409-3p. These results emphasize the importance of the BDNF signaling pathway in improving PSD symptoms and provide a possible mechanism for morroniside to treat PSD.

Mechanisms associated with post-stroke depression and pharmacologic therapy

Stroke is one of the most common cerebrovascular diseases, which is the cause of long-term mental illness and physical disability, Post-stroke depression (PSD) is the most common neuropsychiatric complication after stroke, and its mechanisms are characterized by complexity, plurality, and diversity, which seriously affects the quality of survival and prognosis of patients. Studies have focused on and recognized neurotransmitter-based mechanisms and selective serotonin-reuptake inhibitors (SSRIs) can be used to treat PSD. Neuroinflammation, neuroendocrinology, neurotrophic factors, and the site of the stroke lesion may affect neurotransmitters. Thus the mechanisms of PSD have been increasingly studied. Pharmacological treatment mainly includes SSRIs, noradrenergic and specific serotonergic antidepressant (NaSSA), anti-inflammatory drugs, vitamin D, ect, which have been confirmed to have better efficacy by clinical studies. Currently, there is an increasing number of studies related to the mechanisms of PSD. However, the mechanisms and pharmacologic treatment of PSD is still unclear. In the future, in-depth research on the mechanisms and treatment of PSD is needed to provide a reference for the prevention and treatment of clinical PSD.

Delirium and Previous Psychiatric History Independently Predict Poststroke Posttraumatic Stress Disorder

OBJECTIVES

Delirium is an acute brain dysfunction that has been correlated with adverse mental health outcomes, such as depression and posttraumatic stress disorder (PTSD). However, delirium has not been studied in relation to mental health outcomes after cerebrovascular events. This study aimed to examine the incidence of PTSD after nontraumatic intracerebral hemorrhage (ICH) and identify new predictors of poststroke PTSD symptoms.

METHODS

Clinical data were collected from 205 patients diagnosed with nontraumatic ICH. Demographics and hospital course data were examined. Univariate and multivariable correlational analyses were performed to determine predictors of PTSD symptoms. PTSD symptoms were assessed using PTSD checklist-civilian version (PCL-C) scores.

RESULTS

Diagnostic criteria for a positive PTSD screen (PCL-C score ≥44) were met by 13.7%, 20.2%, and 11.6% of nontraumatic patients with ICH at 3, 6, and 12 months, respectively. On univariate analysis, younger age, female sex, unemployed, and in-hospital delirium were correlated with higher PCL-C scores. In multivariable models, younger age, female sex, unemployed, in-hospital delirium, and a previous anxiety or depression diagnosis were associated with higher PCL-C scores at different follow-up times. Modified Rankin Scale scores were also positively correlated with PCL-C scores at each time point.

CONCLUSIONS

Delirium, previous psychiatric history, younger age, female sex, and unemployment status were found to be associated with a greater degree of posthemorrhagic stroke PTSD symptoms. More significant PTSD symptoms were also correlated with greater functional impairment. A better understanding of patient susceptibility to PTSD symptoms may help providers coordinate earlier interventions.

Lifetime and Acute Stress Predict Functional Outcomes Following Stroke: Findings From the Longitudinal STRONG Study

BACKGROUND

Stroke is a sudden-onset, uncontrollable event; stroke-related stress may impede rehabilitation and recovery. Lifetime stress may sensitize patients to experiencing greater stroke-related stress and indirectly affect outcomes. We examine lifetime stress as predictor of poststroke acute stress and examine lifetime and acute stress as predictors of 3- and 12-month functional status. We also compare acute stress and baseline National Institutes of Health Stroke Scale as predictors of poststroke functional status.

METHODS

Between 2016 and 2020 the STRONG Study (Stroke, Stress, Rehabilitation, and Genetics) enrolled adults with new radiologically confirmed stroke 2 to 10 days poststroke onset at 28 acute care US hospitals. Participants were interviewed 3 times: acute admission (acute stress; Acute Stress Disorder Interview), 3 months (Fugl-Meyer Upper Extremity motor impairment [Fugl-Meyer Upper Arm Assessment; N=431], modified Rankin Scale [3 months; N=542], Stroke Impact Scale-Activities of Daily Living [3 months; N=511], Lifetime Stress Exposure Inventory), and 12 months (modified Rankin Scale, N=533; Stroke Impact Scale 3.0 Activities of Daily Living; N=485; Telephone Montreal Cognitive Assessment; N=484) poststroke. Structural equation models examined whether acute stress predicted 3- and 12-month functional outcomes, and mediated an association between lifetime stress and outcomes controlling for demographics and initial National Institutes of Health Stroke Scale. Standardized betas are reported.

RESULTS

Sample (N=763) was 19 to 95 years old (mean=63; SD=14.9); 448 (58.7%) were male. Acute stress scores ranged from 0 to 14 (mean, 3.52 [95% CI, 3.31-3.73]). Controlling for age, gender, baseline National Institutes of Health Stroke Scale, and race and ethnicity, higher lifetime stress predicted higher acute stress (β=0.18, P<0.001), which predicted lower 3-month Fugl-Meyer Upper Arm Assessment scores (β=-0.19, P<0.001), lower Stroke Impact Scale 3.0 Activities of Daily Living scores at 3 months (β=-0.21, P<0.001) and 12 months (β=-0.21, P<0.001), higher modified Rankin Scale scores at 3 months (β=0.23, P<0.001) and 12 months (β=0.22, P<0.001), and lower 12-month Telephone Montreal Cognitive Assessment scores (β=-0.20, P<0.001). Acute stress predicted 12-month tMoCA (χ2[1]=5.29, P=0.022) more strongly, 3-month and 12-month modified Rankin Scale and SIS scores as strongly (all Ps>0.18), but Fugl-Meyer scores (χ2[1]=7.01, P=0.008) less strongly than baseline National Institutes of Health Stroke Scale.

CONCLUSIONS

Lifetime stress/trauma is associated with more poststroke acute stress, which is associated with greater motor and cognitive impairment and disability 3 and 12 months poststroke. Poststroke interventions for acute stress may help mitigate stroke-related disability.

Exploration of eye movement desensitization and reprocessing in treating posttraumatic stress-disorder in patients with acquired brain injury: a retrospective case series

Background: Posttraumatic stress disorder (PTSD) is prevalent in people with acquired brain injury (ABI). Despite the established efficacy of eye movement desensitization and reprocessing (EMDR) for PTSD in general, evaluation studies on EMDR in ABI patients with PTSD are limited.Objective: The aim of this study is to explore clinical features, treatment characteristics, feasibility and first indications of efficacy of EMDR in adult ABI patients with PTSD.Method: This retrospective consecutive case series included ABI patients, who received at least one session of EMDR for PTSD between January 2013 and September 2020. PTSD symptoms were measured using the Impact of Event Scale (IES) pre- and post-treatment. Affective distress was measured using the Subjective Units of Distress (SUD) pre- and post-treatment of the first target.Results: Sixteen ABI patients (median age 46 years, 50% males), with predominantly moderate or severe TBI (50%) or stroke (25%) were included. Treatment duration was a median of seven sessions. Post-treatment IES scores were significantly lower than pre-treatment scores (p < .001). In 81% of the cases there was an individual statistically and clinically relevant change in IES score. Mean SUD scores of the first target were significantly lower at the end of treatment compared to scores at the start of treatment (p < .001). In 88% of the patients full desensitization to a SUD of 0-1 of the first target was accomplished. Only few adjustments to the standard EMDR protocol were necessary.Conclusions: Findings suggest that EMDR is a feasible, well tolerated and potentially effective treatment for PTSD in ABI patients. For clinical practice in working with ABI patients, it is advised to consider EMDR as a treatment option.

Neurologic Injury-Related Predisposing Factors of Post-Traumatic Stress Disorder: A Critical Examination

The present review aimed to identify the means through which neurologic injury can predispose individuals to Post-Traumatic Stress Disorder (PTSD). In recent years, comprehensive studies have helped to clarify which structures in the central nervous system can lead to distinct PTSD symptoms-namely, dissociative reactions or flashbacks-when damaged. Our review narrowed its focus to three common neurologic injuries, traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), and stroke. We found that in each of the three cases, individuals may be at an increased risk of developing PTSD symptoms. Beyond discussing the potential mechanisms by which neurotrauma may lead to PTSD, we summarized our current understanding of the pathophysiology of the disorder and discussed predicted associations between the limbic system and PTSD. In particular, the effect of noradrenergic neuromodulatory signaling on the hypothalamic pituitary adrenal (HPA) axis as it pertains to fear memory recall needs to be further explored to better understand its effects on limbic structures in PTSD patients. At present, altered limbic activity can be found in both neurotrauma and PTSD patients, suggesting a potential causative link. Particularly, changes in the function of the limbic system may be associated with characteristic symptoms of PTSD such as intrusive memories and acute psychological distress. Despite evidence demonstrating the correlation between neurotrauma and PTSD, a lack of PTSD prognosis exists in TBI, SAH, and stroke patients who could benefit from early treatment. It should be noted that PTSD symptoms often compound with pre-existing issues, further deteriorating health outcomes for these patients. It is ultimately our goal to clarify the relationship between neurotrauma and PTSD so that earlier diagnoses and appropriate treatment are observed in clinic.

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.

Psychometric properties of the post-stroke depression scale in the sequelae stage

Aim

To evaluate the psychometric properties of the Post-Stroke Depression Scale in the Sequelae Stage (PSDS-SS).

Background

The incidence of the sequelae stage Post-Stroke Depression (PSD) is high, and the best screening tools are still lacking. Under this circumstances, our research team developed the PSDS-SS by Delphi method, but its psychometric properties need to be further verified.

Method

This was a cross-sectional study. Seven hundred and sixteen stroke patients in the sequelae stage were enrolled by purpose sampling from May 2022 to September 2022. The exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to verify the factor structure of the scale. The reliability of the scale was tested by Cronbach’s α coefficient, test–retest reliability and composite reliability. The validity of the scale was tested by criterion-related validity, convergent and discriminant validity.

Result

Eight items were deleted through item analysis. The EFA ended up with a 5-factor scale including 24 items after removing one item with low factor loading. Finally, a 21-item model was established by confirmatory factor analysis, and all the fit indexes were acceptable. The reliability and validity of the total scale and each factor are acceptable.

Conclusion

The PSDS-SS has a stable factor structure, and demonstrated good reliability and validity. And it would be an effective tool to assess PSD in the sequelae stage.

Stroke survivors' preferences for post-stroke self-management programs: A discrete choice experiment

BACKGROUND AND PURPOSE

Self-management programs enhance survival in stroke patients. However, they require patient-centered designs to be effective. The aim of this study was therefore to investigate the type of post-stroke self-management programs that appeal to stroke survivors, and to estimate their willingness to participate in such programs.

METHODS

A Discrete Choice Experiment was administered to patients who had either a transient ischemic attack (TIA) or stroke within the past 3 years and were cognitively intact (i.e., stroke survivors). Stroke survivors were presented with eight choice tasks and asked to choose between 'No Program' and two hypothetical post-stroke management programs that varied by six attributes: Topics covered by the program; schedule of the program; frequency and duration of the sessions; number of participants; out-of-pocket registration fee for the whole program; and rewards for completing the program.

RESULTS

The analysis involved 146 stroke survivors. Based on the mixed logit model, the predicted willingness to participate ranged from 53% to 76%. The most popular characteristics in a program were topics on health education and risk management, being scheduled during weekends as four sessions that are each 2 hours long and involve four participants, a registration fee of SGD50 (∼USD36), and SGD500 (∼USD359) reward for program completion.

CONCLUSIONS

Interest in post-stroke self-management programs was high, with at least half of the sample showing interest in participating in these programs. Program features such as focusing on health education and risk management, charging a low registration fee, and offering incentives helped to increase the demand.

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.

Patterns of Health-Related Quality of Life among Stroke Survivors: A Longitudinal Study

Six months poststroke is critical for optimizing stroke survivors' recovery and improving their health-related quality of life (HRQoL). Understanding HRQoL profiles in specific domains can provide a more typical plan for stroke survivors. This pilot study aimed to explore the HRQoL patterns among 39 stroke survivors within 6 months following diagnosis. The results revealed that there were four patterns based on HRQoL domains. Pattern 1: energy, family role, mobility, self-care, social role, and work/productivity domains likely to improve; Pattern 2: language and vision domains likely to improve and be stable; Pattern 3: thinking and upper extremity function domains likely to worsen and improve later; and Pattern 4: mood and personality domains likely to worsen and be constant. Health care providers can apply these results by continuing to assess and provide care to stroke survivors focusing on functional status, cognitive status, and depression over time. Further study should explore the factors predicting HRQoL.

Quantitative EEG as a Biomarker in Evaluating Post-Stroke Depression

Introduction: Post-stroke depression (PSD) has complex pathophysiology determined by various biological and psychological factors. Although it is a long-term complication of stroke, PSD is often underdiagnosed. Given the diagnostic role of quantitative electroencephalography (qEEG) in depression, it was investigated whether a possible marker of PSD could be identified by observing the evolution of the (Delta + Theta)/(Alpha + Beta) Ratio (DTABR), respectively the Delta/Alpha Ratio (DAR) values in post-stroke depressed patients (evaluated through the HADS-D subscale). Methods: The current paper analyzed the data of 57 patients initially selected from a randomized control trial (RCT) that assessed the role of N-Pep 12 in stroke rehabilitation. EEG recordings from the original trial database were analyzed using signal processing techniques, respecting the conditions (eyes open, eyes closed), and several cognitive tasks. Results: We observed two significant associations between the DTABR values and the HADS-D scores of post-stroke depressed patients for each of the two visits (V1 and V2) of the N-Pep 12 trial. We recorded the relationships in the Global (V1 = 30 to 120 days after stroke) and Frontal Extended (V2 = 90 days after stroke) regions during cognitive tasks that trained attention and working memory. For the second visit, the association between the analyzed variables was negative. Conclusions: As both our relationships were described during the cognitive condition, we can state that the neural networks involved in processing attention and working memory might go through a reorganization process one to four months after the stroke onset. After a period longer than six months, the process could localize itself at the level of frontal regions, highlighting a possible divergence between the local frontal dynamics and the subjective well-being of stroke survivors. QEEG parameters linked to stroke progression evolution (like DAR or DTABR) can facilitate the identification of the most common neuropsychiatric complication in stroke survivors.

Association of Psychosocial Stress With Risk of Acute Stroke

IMPORTANCE

Psychosocial stress is considered a modifiable risk factor for stroke. Given the prevalence of chronic and acute exposure to stress, it represents a potentially attractive target for population-health interventions.

OBJECTIVES

To determine the association of psychosocial stress with the risk of acute stroke and explore factors that might modify the association of stress with risk of acute stroke in a large international population.

DESIGN, SETTING, AND PARTICIPANTS

INTERSTROKE is an international retrospective case-control study of risk factors for first acute stroke in 32 countries in Asia, North and South America, Europe, Australia, the Middle East, and Africa. A total of 13 462 patients with stroke and 13 488 matched controls were recruited between January 11, 2007, and August 8, 2015. The present analyses were performed from June 1 to 30, 2021, and included 13 350 cases and 13 462 controls with available data on psychosocial stress.

EXPOSURES

Psychosocial stress and occurrence of stressful life events within the preceding year were measured using a standardized questionnaire of self-reported stress at home and work.

MAIN OUTCOMES AND MEASURES

The association of stress with acute stroke and its subtypes was examined using multivariable conditional logistic regression and factors that might modify the association, particularly self-reported locus of control.

RESULTS

Among 26 812 participants included in the analysis, the mean (SD) age of cases was 62.2 (13.6) years; that of controls, 61.3 (13.3) years; 7960 cases (59.6%) and 8017 controls (59.6%) were men. Several periods of stress and permanent stress were reported for 2745 cases (20.5%) and 1933 controls (14.4%), with marked regional variation in prevalence, with the lowest in China (201 of 3981 [5.0%] among controls and 364 of 3980 [9.1%] among cases) and highest in South East Asia (233 of 855 [26.1%] among controls and 241 of 782 [30.8%] among cases). Increased stress at home (odds ratio [OR], 1.95 [95% CI, 1.77-2.15]) and at work (OR, 2.70 [95% CI, 2.25-3.23]) and recent stressful life events (OR, 1.31 [95% CI, 1.19-1.43]) were associated with an increased risk of acute stroke on multivariable analyses (vs no self-reported stress). Higher locus of control at home was associated with a reduced odds of all stroke (OR, 0.73 [95% CI, 0.68-0.79]), and higher locus of control both at work and at home were associated with a lower odds of acute stroke and significantly diminished the association with stress at work (OR, 2.20 [95% CI, 1.88-2.58]; P = .008 for interaction) and home (OR, 1.69 [95% CI, 1.44-1.98]; P < .001 for interaction) for acute stroke.

CONCLUSIONS AND RELEVANCE

Psychosocial stress is a common risk factor for acute stroke. The findings of this case-control study suggest that higher locus of control is associated with lower risk of stroke and may be an important effect modifier of the risk associated with psychosocial stress.

Parental migration status moderates the link between parent-child relationship and children's well-being through psychological distress

The effects of parental migration on the well-being of left-behind children (LBC) are varied. Several studies demonstrated that parental migration reduces children's psychological health but other research showed contradictory results. This study sought to clarify this issue by examining the mediating role of psychological distress and the moderating role of parental migration status in the association between the parent-child relationship and children's psychological distress. A total of 743 LBC and 688 non-LBC self-reported their parent-child relationship, psychological distress, and well-being. Findings showed that psychological distress mediated the association between parent-child relationship and children's well-being. This denotes that greater parent-child relationship results into lowered levels of psychological distress, and in turn, increases children's emotional, psychological, and social well-being. Moreover, the link between parent-child relationship and psychological distress was found to be contingent to parental migration status. Specifically, the negative association between parent-child relationship and psychological distress was especially strong among LBC in contrast to non- LBC. This implies that children with higher quality relationships with their parents tend to exhibit decreased severity of psychological distress symptoms, especially in children whose parents are working overseas. These results underscore the dynamic role of parent-child relationship in the well-being of LBC, and suggest ways to develop intervention programs that include cultivating skills in managing psychological distress and improving the emotional, psychological, and social well-being of LBC.

Contributing Factors and Induced Outcomes of Psychological Stress Response in Stroke Survivors: A Systematic Review

Background

Remarkable evidence indicates that psychological stress is significantly associated with stroke. However, a uniform recommendation to identify and alleviate poststroke psychological stress responses and improve postmorbid outcomes is not currently available. Thus, this systematic review aimed to summarize the types of poststroke psychological stress, measurement tools, contributing factors, and outcomes.

Methods

This systematic review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. A literature search was conducted in PubMed, Web of Science, Embase, CNKI, WanFangData, and CQVIP from database inception to November 2021. Cross-sectional and longitudinal studies were included in this research. Quality assessment was performed based on the National Institutes of Health (NIH) Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies.

Results

Eighteen quantitative, peer-reviewed studies were included for analysis. Selected articles mainly investigated perceived stress and posttraumatic stress disorder after stroke. We classified the contributing factors into four categories: sociodemographic factors, clinical disease factors, psychological factors, and behavioral and lifestyle factors. The postmorbid outcomes were divided into three categories: clinical disease outcomes, psychological outcomes, and behavioral and quality of life outcomes.

Conclusions

Compared to common patients, stroke survivors with the following characteristics suffered an increased psychological stress response: younger age, the presence of caregivers, depression, unsuitable coping strategies, etc. Meanwhile, lower quality of life, worse drug compliance, worse functional independence, and more severe mental disorders were significantly associated with increased psychological stress symptoms. Further studies are required to provide more trustworthy and meaningful references for mitigating the damage caused by psychological stress after stroke.

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

PURPOSE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSIONS

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

Emotional distress in neuro-ICU survivor-caregiver dyads: The recovering together randomized clinical trial

OBJECTIVE

Emotional distress is common in both survivors and their informal caregivers following admission to a neuroscience intensive care unit (Neuro-ICU) and can negatively affect their individual recovery and quality of life. Neuro-ICU survivor-caregiver dyads can influence each other's emotional distress over time, but whether such influence emerges during dyadic treatment remains unknown. The present study involved secondary data analysis of Neuro-ICU dyads enrolled in a randomized clinical trial of a dyadic resiliency intervention, Recovering Together (RT), versus a health education attention placebo control to test dyadic similarities in emotional distress before and after treatment.

METHOD

Data were collected from 58 dyads following Neuro-ICU admission. Emotional distress (depression, anxiety, and posttraumatic stress) was assessed at baseline, 6 weeks (postintervention), and 12 weeks later. Nonindependence within survivor-caregiver dyads was examined (i.e., correlations between cross-sectional symptoms and changes in symptoms over time); mutual influence of emotional functioning over time (i.e., "partner effects") was examined using cross-lagged path analyses.

RESULTS

There were strong, positive cross-sectional correlations between survivor and caregiver distress at postintervention and follow-up and between changes in survivor and caregiver distress from baseline to postintervention and postintervention to follow-up. There were no partner effects.

CONCLUSIONS

Neuro-ICU survivors and their informal caregivers show similar changes in emotional distress after treatment. These findings highlight the potential benefits of intervening on both survivor and caregiver distress following Neuro-ICU admission. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A Person-Centered Approach Understanding Stroke Survivor and Family Caregiver Emotional Health

ABSTRACT

BACKGROUND: The purpose of this study was to incorporate a person-centered approach to understand the emotional health needs and perspectives of stroke survivors (SSs) and their caregivers. METHODS: In collaboration with 4 SSs and caregivers as research partners, quantitative data were collected to assess poststroke emotional health needs, and qualitative data were collected to gain insight into SS and caregiver emotional health perspectives after stroke. RESULTS: Forty surveys (n = 26 SSs, n = 14 caregivers) were collected. The predominate emotional health needs were frustration (65%), anxiety (54%), and stress (50%) for SSs and stress (71%), worry (57%), and frustration (57%) for caregivers. Two group interviews (n = 7 SSs, n = 3 caregivers) were completed. Four emerging themes were identified: receiving support from those in similar situations, poststroke emotional responses, situations experienced in healthcare settings, and a hypervigilance for sudden and unexpected events. CONCLUSION: Emotional healthcare services for SSs and their caregivers may consider providing reoccurring mental health education and multifaceted treatment approaches, including provision of peer support, and addressing the unique emotional stressors SSs and caregivers may be experiencing. The small sample size precludes generalizing the results into the broader stroke population. However, by leveraging the lived experience of SSs and their caregivers, the results may help find ways to support SSs' and caregivers' emotional health.

Functional seizures are associated with cerebrovascular disease and functional stroke is more common in patients with functional seizures than epileptic seizures

PURPOSE

To characterize the relationship between functional seizures (FSe), cerebrovascular disease (CVD), and functional stroke.

METHOD

A retrospective case-control study of 189 patients at a single large tertiary medical center. We performed a manual chart review of medical records of patients with FSe or epileptic seizures (ES), who also had ICD code evidence of CVD. The clinical characteristics of FSe, ES, CVD, and functional stroke were recorded. Logistic regression and Welch's t-tests were used to evaluate the differences between the FSe and ES groups.

RESULTS

Cerebrovascular disease was confirmed in 58.7% and 87.6% of patients with FSe or ES through manual chart review. Stroke was significantly more common in patients with ES (76.29%) than FSe (43.48%) (p = 4.07 × 10^-6). However, compared to nonepileptic controls FSe was associated with both CVD (p < 0.0019) and stroke (p < 6.62 × 10^-10). Functional stroke was significantly more common in patients with FSe (39.13%) than patients with ES (4.12%) (p = 4.47 × 10^-9). Compared to patients with ES, patients with FSe were younger (p = 0.00022), more likely to be female (p = 0.00040), and more likely to have comorbid mental health needs including anxiety (p = 1.06 × 10^-6), PTSD or history of trauma (e.g., sexual abuse) (p = 1.06 × 10^-13), and bipolar disorder (p = 0.0011).

CONCLUSION

Our results confirm the initial observation of increased CVD in patients with FSe and further suggest that patients with FSe may be predisposed to developing another functional neurological disorder (FND) (i.e., functional stroke). We speculate that this may be due to shared risk factors and pathophysiological processes that are common to various manifestations of FND.

A Conceptual Model of the Influence of Mindfulness-Based Interventions on Stress and Quality of Life in Patients With Chronic Conditions

Individuals with chronic conditions are susceptible to stress-related health complications. Left unattended, chronic stress exacerbates inflammation, diminishes quality of life (QOL), and increases all-cause mortality. Here, we suggest a theoretical framework promoting the use of mindfulness-based interventions (MBIs) in patients with chronic conditions and a conceptual model of how MBIs may influence stress and QOL.

The Effect of Psychosocial Factors and Functional Independence on Poststroke Depressive Symptoms: A Cross-Sectional Study

BACKGROUND

Stroke is the second leading cause of death and a major cause of serious, long-term disability worldwide. The approximately 15 million people each year who experience stroke are at risk of developing depression. Poststroke depressive symptoms affect one third of survivors of stroke. Patients who develop poststroke depressive symptoms experience decreased functional independence, poor cognitive recovery, decreased quality of life, and increased mortality. Survivors of stroke use social support to deal with stress and defend against the adverse effects of negative stroke outcomes.

PURPOSE

This study was designed to examine the influence of perceived social support (emotional and informational, tangible, affectionate, and positive social interaction), stress level, and functional independence on depressive symptoms in survivors of stroke.

METHODS

A cross-sectional observational study design in outpatient settings and rehabilitation centers was conducted. A convenience sample of 135 survivors of stroke completed the psychometrically valid instruments.

RESULTS

Most of the sample had mild or moderate depressive symptoms (26% and 29%, respectively). The mean score for perceived social support was 77.53 (SD = 21.44) on the Medical Outcomes Study Social Support Survey. A negative association was found between depressive symptoms and the social support total score (r = -.65, p < .01). All of the social support subcategories were negatively associated with depressive symptoms. Hierarchical multiple linear regression showed that social support, stress level, and literacy were associated with depressive symptoms (β = -.31, p < .001; β = .45, p < .001; and β = .16, p = .01, respectively) and partially mediated the association between depressive symptoms and functional independence.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Poststroke depressive symptoms are common among survivors of stroke. Social support may improve health by protecting these individuals from the negative outcomes of stroke and enhance their recovery. Future research is required to examine how related interventions improve social support in caregivers and reduce depressive symptoms in stroke survivors.

Occurence of Post-Traumatic Stress Symptoms, Anxiety and Depression in the Acute Phase of Transient Ischemic Attack and Stroke

Rates of post-traumatic stress symptoms, anxiety and depression are increased in patients having experienced a transient ischemic attack (TIA) or stroke several months ago. However, data of psychiatric symptoms in the acute phase within the first days after ictus are lacking. In 20 patients with stroke and 33 patients with TIA we assessed disease severity by means of the NIHSS, levels of depression and anxiety by HADS, PTSD-like symptoms by PC-PTSD, quality of life (HrQoL) by SF-12, and coping style by brief COPE Inventory within the first 5 days after ictus. NIHSS on admission was lower in patients with TIA (0 ± 1) than in patients with stroke (3 ± 2, p < 0.001). HADS depression score was significantly higher in patients with stroke (7.0 ± 4.5) than in patients with TIA (4.9 ± 4.0). HADS anxiety score, HrQoL and coping styles were similar between TIA and stroke patients (p > 0.05). 5 and 3 of 33 TIA patients as well as 4 and 3 of 20 stroke patients had at least 11 points in the HADS anxiety and depression score respectively (p = 0.001). 2 of 33 TIA patients and 2 of 20 stroke patients had more than 2 points in the PC-PTSD (p = 0.646). We did not find consistent correlations between the NIHSS and the psychometric parameters. Within the first five days after patients having experienced a TIA or stroke PTSD-like, anxious and depressive symptoms are more common than in the general population. As the acute psychological status after ictus is predictive for psychiatric comorbidity years later physicians should pay attention and adequately treat psychiatric symptoms already in the acute phase of stroke.Trial Registration: German Clinical Trials Register, DRKS00021730, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00021730 , registered 05/19/2020- Retrospectively registered.

Prevalence and influencing factors of chronic post-traumatic stress disorder in patients with myocardial infarction, transient ischemic attack (TIA) and stroke - an exploratory, descriptive study

BACKGROUND

Cardio- and cerebrovascular events such as myocardial infarction (MI), stroke and transient ischemic attack (TIA) are leading causes of death and disability and have also been associated with poor mental outcomes. In addition, cardio- and cerebrovascular events may pose the risk of experiencing a sudden traumatic occurrence of symptoms during ictus and thus contribute to high rates of PTSD as well as high rates of subsequent depression and anxiety. Moreover, MI, TIA and stroke survivors with PTSD, depressive and anxiety symptoms may have poorer health-related quality of life (HRQoL) and poorer disease prognosis than patients who do not develop psychiatric symptoms after ictus. However, data on the prevalence of PTSD, anxiety and depression, as well as the HRQoL, coping strategies and potential risk factors for development of PTSD in these patients, are rare.

METHODS

In an exploratory, descriptive study we interviewed 112 patients (54 MI, 18 TIA, 40 stroke; mean age: 69.5 years, 55.4% males) from three general physician practices and used psychometric self-assessment tools to determine the occurrence of PTSD and psychosomatic comorbidity, anxiety and depression and to assess HRQoL and coping strategies. We evaluated disease severity and compared the patient groups to each other. Moreover, we assessed psychological outcome differences between patients with or without PTSD after ictus.

RESULTS

The prevalence of PTSD after MI, TIA and stroke was 23.2%. The patients who developed PTSD had higher rates of depression, anxiety and maladaptive coping as well as reduced HRQoL. Adaptive coping was positively related to better mental HRQoL and negatively related to anxiety and depression. Disease severity of MI, TIA and stroke was not related to PTSD, depression, anxiety or physical HRQoL.

CONCLUSIONS

Experiencing MI, TIA or stroke means confronting a life-threatening event for those affected and, therefore, these can be regarded as traumatic events. Cerebral and cardiovascular events increase the risk of developing chronic PTSD with subsequent increased depression and anxiety and reduced HRQoL. These findings emphasize the need for early screening and diagnosis of PTSD in somatically ill patients, which should be followed by specialized treatment, as PTSD hampers overall (somatic) disease prognosis.

Posttraumatic stress disorder prevalence in medical populations: A systematic review and meta-analysis

OBJECTIVE

PTSD is increasingly recognized following medical traumas although is highly heterogeneous. It is difficult to judge which medical contexts have the most traumatic potential and where to concentrate further research and clinical attention for prevention, early detection and treatment. The objective of this study was to compare PTSD prevalence in different medical populations.

METHODS

A systematic review of the literature on PTSD following medical traumas was conducted as well as a meta-analysis with final pooled result and 95% confidence intervals presented. A meta-regression was used to investigate the impact of potential effect modifiers (PTSD severity, age, sex, timeline) on study effect size between prevalence studies.

RESULTS

From 3278 abstracts, the authors extracted 292 studies reporting prevalence. Using clinician-administered reports, the highest 24 month or longer PTSD prevalence was found for intraoperative awareness (18.5% [95% CI=5.1%-36.6%]) and the lowest was found for epilepsy (4.5% [95% CI=0.2%-12.6%]). In the overall effect of the meta-regression, only medical events or procedures emerged as significant (p = 0.006) CONCLUSION: This review provides clinicians with greater awareness of medical contexts most associated with PTSD, which may assist them in the decision to engage in more frequent, earlier screening and referral to mental health services.

Myricetin as a Promising Molecule for the Treatment of Post-Ischemic Brain Neurodegeneration

The available drug therapy for post-ischemic neurodegeneration of the brain is symptomatic. This review provides an evaluation of possible dietary therapy for post-ischemic neurodegeneration with myricetin. The purpose of this review was to provide a comprehensive overview of what scientists have done regarding the benefits of myricetin in post-ischemic neurodegeneration. The data in this article contribute to a better understanding of the potential benefits of myricetin in the treatment of post-ischemic brain neurodegeneration, and inform physicians, scientists and patients, as well as their caregivers, about treatment options. Due to the pleiotropic properties of myricetin, including anti-amyloid, anti-phosphorylation of tau protein, anti-inflammatory, anti-oxidant and autophagous, as well as increasing acetylcholine, myricetin is a promising candidate for treatment after ischemia brain neurodegeneration with full-blown dementia. In this way, it may gain interest as a potential substance for the prophylaxis of the development of post-ischemic brain neurodegeneration. It is a safe substance, commercially available, inexpensive and registered as a pro-health product in the US and Europe. Taken together, the evidence available in the review on the therapeutic potential of myricetin provides helpful insight into the potential clinical utility of myricetin in treating neurodegenerative disorders with full-blown dementia. Therefore, myricetin may be a promising complementary agent in the future against the development of post-ischemic brain neurodegeneration. Indeed, there is a scientific rationale for the use of myricetin in the prevention and treatment of brain neurodegeneration caused by ischemia.

Symptom clusters of early-stage poststroke depression: A mixed-methods study

Aim

To identify the symptom clusters of early‐stage poststroke depression (PSD) and provide an in‐depth understanding of the symptoms.

Design

A mixed‐methods study with a convenient sampling method was used.

Methods

A cross‐sectional questionnaire survey in 231 stroke patients and semi‐structured interviews in 14 stroke patients were conducted in the neurological department of a comprehensive hospital in Southeast China. Data from the questionnaire survey were analysed through descriptive and exploratory factor analyses; data from the semi‐structured interview were transcribed verbatim and analysed through inductive content analysis. This study adheres to the GRAMMS checklist.

Results

Exploratory factor analysis revealed six symptom clusters of early‐stage PSD that accounted for an ideal variance in PSD: nervous, wakefulness, emotional, dull, guilt and low mood. Further, inductive content analysis revealed five themes that were like the above symptom clusters, except for the dull symptom cluster.

Relationship between NIH stroke symptoms and post-traumatic stress disorder in patients evaluated for transient ischemic attack/stroke

OBJECTIVE

Post-traumatic stress disorder (PTSD) can develop after a life-threatening medical event. According to the enduring somatic treat (EST) model, internal somatic cues (e.g., rapid heart rate) may contribute to symptoms of stroke/TIA-induced PTSD. To address this possibility, the present study tested the association of stroke-induced disability with PTSD symptoms in patients treated for stroke or transient ischemic attack (TIA).

METHOD

Participants (n = 300) were drawn from an observational cohort study examining PTSD symptoms in patients admitted to the NewYork Presbyterian Hospital between 2015 and 2017 for a stroke/TIA. Patients self-reported acute stress symptoms in-person approximately 3 days post-stroke/TIA and PTSD symptoms via telephone one month later. Severity of stroke symptoms (i.e., stroke disability) was evaluated using the NIH Stroke Scale prior to hospital discharge.

RESULTS

Stroke disability had a significant, positive association with acute stress symptoms early post-stroke/TIA, B = 0.46, se = 0.15, p = .002, and with PTSD symptoms one month later, B = 0.56, se = 0.19, p = .003.

CONCLUSIONS

Stroke disability is positively associated with both acute distress and PTSD symptoms one month later following a stroke/TIA, supporting the hypothesis that internal somatic symptoms contribute to the development stroke/TIA-induced PTSD symptoms.

Neuropsychiatric issues after stroke: Clinical significance and therapeutic implications

A spectrum of neuropsychiatric disorders is a common complication from stroke. Neuropsychiatric disorders after stroke have negative effects on functional recovery, increasing the rate of mortality and disability of stroke survivors. Given the vital significance of maintaining physical and mental health in stroke patients, neuropsychiatric issues after stroke have raised concerns by clinicians and researchers. This mini-review focuses on the most common non-cognitive functional neuropsychiatric disorders seen after stroke, including depressive disorders, anxiety disorders, post-traumatic stress disorder, psychosis, and psychotic disorders. For each condition, the clinical performance, epidemiology, identification of the therapeutic implication, and strategies are reviewed and discussed; the main opinions and perspectives presented here are based on the latest controlled studies, meta-analysis, or updated systematic reviews. In the absence of data from controlled studies, consensus recommendations were provided accordingly.

Percutaneous mastoid electrical stimulator improves Poststroke depression and cognitive function in patients with Ischaemic stroke: a prospective, randomized, double-blind, and sham-controlled study

Background

Poststroke depression can lead to functional dependence, cognitive impairment and reduced quality of life. The aim of this study was to evaluate the effects of a percutaneous mastoid electrical stimulator (PMES) plus antidepressants on poststroke depression and cognitive function.

Methods

This study was a prospective, randomized, double-blind, and sham-controlled study. A total of 258 clinically depressed ischaemic stroke patients within 14 days of index stroke were randomly assigned to the PMES plus antidepressant (PMES group, N = 125) and sham plus antidepressant (sham group, N = 133) groups. All patients underwent the Montreal Cognitive Assessment (MoCA) and Hamilton Rating Scale for Depression (HRSD) test at 2 weeks (baseline), and 6 months(M6) after ischaemic stroke. Primary outcomes were the percentage of patients showing a treatment response (≥50% reduction in HRSD score) and depression remission (HRSD score ≤ 9) at 6 months. The secondary outcome was the percentage of patients with a MoCA score < 26.

Results

The percentages of patients showing a treatment response and depression remission were significantly higher in the PMES group than in the sham group (57.60% vs 41.35%, P = 0.009; 44.00% vs 29.32%, P = 0.014 respectively). The mean value of the HRSD score change [M (month)6-baseline] was significantly higher in the PMES group than in the sham group at 6 months (− 11.93 ± 5.32 vs − 10.48 ± 6.10, P = 0.036, respectively). The percentage of patients with MoCA scores < 26 was lower in the PEMS group than in the sham group (12.0% vs 24.06%, P = 0.012,respectively), and the mean value of the MoCA score change (M6-baseline) was higher in the PMES group than in the sham group (3.50 ± 2.55 vs 2.72 ± 2.52, P = 0.005, respectively).

Conclusion

These findings demonstrate that PMES adjunctive to antidepressant therapy is effective in reducing depression, achieving remission in the short term, and improving cognition.

Post-stroke depression and functional impairments - A 3-year prospective study

BACKGROUND

Post-Stroke Depression (PSD) is a severe condition, affecting about 30% of stroke survivors within a five-year period after stroke. Post-stroke functional impairments (FI) and social support are associated with PSD. It is inconclusive, whether one of the factors, post-stroke FI and PSD, shows a stronger predictive value on the respective other over time. The aims of the present study were to 1) investigate the relationship between PSD, FI, and social support of stroke patients in a 3-year prospective design, and 2) address methodological shortcomings of previous studies.

METHODS

We investigated 174 stroke survivors and assessed PSD with a structured clinical interview and a dimensional symptom rating scale. We conducted regression analyses and applied the approach of multiple imputations (MI) for missing data due to dropout during follow-up.

RESULTS

PSD prevalence was 32.2% in the acute phase after stroke. Individuals with a PSD in this phase revealed a fivefold higher risk for PSD 3 years later. FI in the acute phase did not additionally contribute to the prediction of PSD at follow-up. Compared to individuals without PSD in the acute phase, individuals with PSD had an increased risk for FI at follow-up. Limitations regarding sample characteristics, design, and dropout are discussed.

CONCLUSIONS

Results indicate that PSD rather than FI represents a crucial risk factor for negative long-term consequences regarding physical and psychological health after stroke. Post-stroke treatment might be optimized by a routine assessment of PSD and FI after stroke and considering the results for personalized treatment options.

Construction of a Risk Model Associated with Prognosis of Post-Stroke Depression Based on Magnetic Resonance Spectroscopy

PURPOSE

This study aimed to develop a risk prediction model for post-stroke depression (PSD) based on magnetic resonance (MR) spectroscopy.

PATIENTS AND METHODS

Data of 61 patients hospitalized with stroke (November 2017-March 2019) were retrospectively analyzed. After 61 patients had been admitted to hospital for routine clinical information collection, when the patients were in stable condition, proton MR spectroscopy (¹H-MRS) examinations were performed to measure the ratio of choline to creatine (Cho/Cr) and N-acetylaspartate to creatine (NAA/Cr) in brain regions related to emotion. From the second month to the sixth month after the onset, these 61 patients were assessed by the Hamilton Depression Scale once a month. Based on the scores, patients were divided into PSD and post-stroke non-depression (N-PSD) groups. Twenty-two characteristics were extracted from clinical data and the ¹H-MRS imaging indexes. The least absolute shrinkage and selection operator (LASSO) regression was used for optimal feature selection and the nomogram prediction model was established. The model's predictive ability was validated by a calibration plot and the area under the curve (AUC) of the receiver operating characteristic curve.

RESULTS

Two demographic characteristics (activities of daily living and initial National Institutes of Health Stroke Scale scores) and three ¹H-MRS imaging characteristics (frontal-lobe Cho/Cr, temporal-lobe Cho/Cr, and anterior cingulated-cortex Cho/Cr) were screened out by LASSO regression. The consistency test through the calibration plot found that the predicted probability of the nomogram for PSD correlates well with the actual probability. The AUCs for internal validation and external validation were 0.8635 and 0.8851, respectively.

CONCLUSION

The PSD risk model based on ¹H-MRS may help guide early treatment of stroke and prevent progression to PSD.
