RESUMO
BACKGROUND: Due to the rapid growth of the world´s oldest population, the number of older persons with stroke is expected to rise. Knowledge of stroke etiology is essential to offer personalized and equal health care across age groups. The present systematic review aimed to investigate the prevalence of etiological subtypes of ischemic and hemorrhagic stroke in older compared to younger people. METHODS: MEDLINE, Embase, Cochrane, Epistemonikos, and Cinahl were systematically searched for studies regarding etiological classification in people ≥80 years compared to those <80 years with ischemic or hemorrhagic stroke. RESULTS: Out of 28 441 identified articles, eight met the inclusion criteria. In total, 8223 individuals were included in meta-analyses, of whom 2997 were 80 years or older. We demonstrated a higher prevalence of cardioembolic stroke in people ≥80 years OR 1.68 (95% CI, 1.12-2.53). Small vessel disease was significantly less common in older people OR .64 (95% CI, .50-.81). Regarding large vessel disease, no statistically significant difference between the two groups was shown OR 1.05 (95% CI, .77-1.43). CONCLUSION: In people ≥80 years, cardioembolic stroke is more common, and small vessel disease less common compared to people <80 years. Overall, the results have to be interpreted with caution due to few studies. Large studies using validated classification systems are needed.

INTRODUCTION: Transcranial Doppler (TCD) sonography is a noninvasive tool for measuring cerebrovascular hemodynamics. Studies have reported alterations in cerebrovascular hemodynamics in normal aging, mild cognitive impairment (MCI), and dementia, as well as in different etiologies of dementia. This systematic review and meta-analysis was designed to investigate the relationship between cerebral blood velocity (CBv) and pulsatility index (PI) in the middle cerebral artery (MCA) in persons with MCI and dementia. METHODS: A systematic literature search was conducted in Pubmed, Embase, Cochrane Library, Epistemonikos, PsychINFO, and CINAHL. The search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. After screening of 33,439 articles, 86 were reviewed in full-text, and 35 fulfilled the inclusion criteria. RESULTS: CBv was significantly lower and PI significantly higher in MCA in vascular dementia (VaD) and Alzheimer's disease (AD) compared to cognitively normal (CN) older persons. Also, CBv was lower in MCI compared to CN. There were no significant differences in CBv in MCA in AD compared with VaD, although PI was higher in VaD compared to AD. CONCLUSION: Alterations in cerebrovascular hemodynamics are seen in AD, VaD, and MCI. While PI was slightly higher in VaD compared to AD, the reduction in CBv appears to be equally pronounced across neurodegenerative and vascular etiologies of dementia.

BACKGROUND: Apathy is one of the most prevalent neurobehavioral manifestations in mild cognitive impairment (MCI) and is included among the behavioral and psychological symptoms of dementia (BPSD). Studies suggest that the presence of apathy could be associated with increased dementia risk. The role of apathy in conversion from MCI to dementia, and whether apathy could be a relevant predictor for dementia progression, are still matters of investigation. AIM: To study the relationship between apathy and progression to dementia in individuals with MCI. METHODS: A systematic literature search in Medline, Embase, Cochrane Library, Epistemonikos, PsychINFO, and CINAHL was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search included longitudinal studies reporting on the association between apathy and dementia. RESULTS: The main outcome was pooled unadjusted hazard ratios (HR) of apathy in dementia conversion and included 11 studies with 9504 individuals. There was a significant association between apathy and dementia conversion, HR = 1.54; 95% CI, 1.29, 1.84. Subgroup analysis showed a significant association between apathy and progression to AD. CONCLUSION: Apathy was associated with an increased risk of conversion to AD and all-cause dementia in patients with MCI. The role of apathy as a marker for incident dementia needs to be investigated in large, high-quality studies.

Even mild strokes may affect the patients' everyday life by impairing cognitive and emotional functions. Our aim was to study predictors of such impairments one year after first-ever mild stroke. We included cognitively healthy patients ≤ 70 years with acute mild stroke. Vascular risk factors, sociodemographic factors and stroke classifications were recorded. At one-year post-stroke, different domains related to cognitive and emotional function were assessed with validated instruments. Logistic regression analyses were performed to identify predictors of cognitive and emotional outcome. Of 117 patient assessed at follow-up, only 21 patients (18%) scored within the reference range on all cognitive and emotional assessments. Younger age, multiple infarcts, and being outside working life at stroke onset were independent predictors of cognitive impairments (psychomotor speed, attention, executive and visuospatial function, memory). Female gender and a higher National Institutes of Health Stroke Scale (NIHSS) score at discharge were significantly associated with emotional impairments (anxiety, depressive symptoms, fatigue, apathy, emotional lability) after one year, but these associations were only seen in the unadjusted models. In conclusion, patients in working age may profit from a follow-up during the post-stroke period, with extra focus on cognitive and emotional functions.

OBJECTIVE: We performed a systematic review and meta-analysis to study the relationship between cognitive functioning and phenotypic frailty status. METHODS: We searched Pubmed, Cochrane Library and Epistemonikos from 2000 until March 2022, and used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Samples included both sexes, age ≥55 years, assessed with standardized measures of the different cognitive domains and the frailty phenotype model and analyzing the relationship between the frailty subtypes pre-frail, frail and robust and specific cognitive function. RESULTS: Eleven studies published from 2008 until March 2022 fulfilled the inclusion criteria, and 10 were included in our meta-analyses. Sample sizes varied from 104 to 4649 individuals. Mean Mini-Mental State Examination (MMSE) scores ranged from 17.0 to 27.6, with mean difference (MD) of -2.55 (95% confidence interval [CI] -3.32, -1.78) in frail compared to robust, MD -1.64 (95% CI -2.21, -1.06) in frail compared to prefrail and MD -0.68 (95% CI -0.94, -0.43) in prefrail compared to robust. In subgroup analyses, frail persons had lower scores in the memory domain with standardized mean difference (SMD) -1.01 (95% CI -1.42, -0.59). CONCLUSION: MMSE scores were significantly lower in frail compared to robust and prefrail persons and in prefrail compared to robust persons. Subgroup analysis of memory revealed significantly poorer scores in frail compared to robust. The results indicate a strong relationship between physical frailty and cognitive impairment suggesting incorporation of cognitive function in frailty assessments.

BACKGROUND: Emerging evidence suggests that cognitive impairment (CI) and different etiologies of dementia, including Alzheimer's disease (AD), are associated with vascular risk factors and atherosclerosis. In clinical practice, carotid intima-media thickness (CIMT) measured by ultrasonography may be a marker of atherosclerosis. Many studies report increased CIMT in patients with dementia and CI although a firm association has not yet been established. AIM: This systematic review and meta-analysis were conducted to study the relationship between CIMT, dementia, and CI. METHODS: The literature search was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and included the following databases: Medline, Embase, Cochrane Library, and Epistemonikos. The search spanned from 2000 to 2020 and was limited to English and Scandinavian languages. RESULTS: The main analysis of CIMT in subjects with CI compared to subjects with no cognitive impairment (NCI) included 12 studies; 1,089 subjects with CI and 5,223 with NCI. There was no significant difference in CIMT between the CI and NCI groups. However, subgroup analyses revealed significantly higher CIMT in the mild cognitive impairment (MCI) and dementia groups than the NCI group. In addition, patients with dementia had increased CIMT compared to patients with MCI, and patients with AD demonstrated higher CIMT than those with vascular cognitive impairment (VCI). CONCLUSION: CIMT may be higher in subjects with CI than in cognitively healthy subjects although no significant difference was observed in our main analysis. CIMT was higher in the dementia group than the MCI group and in the AD group compared to the VCI group.

BACKGROUND: Stroke survivors are known to have poorer health-related quality of life (HRQoL) than the general population, but less is known about characteristics associated with HRQoL decreasing through time following a stroke. This study aims to examine how in-hospital frailty is related to HRQoL from 3 to 18 months post stroke. METHOD: Six hundred twenty-five participants hospitalised with stroke were included and followed up at 3 and/or 18 months post stroke. Stroke severity was assessed the day after admission with the National Institutes of Health Stroke Scale (NIHSS). A modified Fried phenotype was used to assess in-hospital frailty; measures of exhaustion, physical activity, and weight loss were based on pre-stroke status, while gait speed and grip strength were measured during hospital stay. HRQoL at 3- and 18-months follow-up were assessed using the five-level version of the EuroQol five-dimensional descriptive system (EQ-5D-5L) and the EuroQol visual analogue scale (EQ-5D VAS). We conducted linear mixed effect regression analyses unadjusted and adjusted for sex, age, and stroke severity to investigate the association between in-hospital frailty and post-stroke HRQoL. RESULTS: Mean (SD) age was 71.7 years (11.6); mean NIHSS score was 2.8 (4.0), and 263 (42.1%) were female. Frailty prevalence was 10.4%, while 58.6% were pre-frail. The robust group had EQ-5D-5L index and EQ-5D VAS scores at 3 and 18 months comparable to the general population. Also at 3 and 18 months, the pre-frail and frail groups had significantly lower EQ-5D-5L indices than the robust group (p < 0.001), and the frail group showed a larger decrease from 3 to 18 months in the EQ-5D-5L index score compared to the robust group (- 0.056; 95% CI - 0.104 to - 0.009; p = 0.021). There were no significant differences in change in EQ-5D VAS scores between the groups. CONCLUSION: This study on participants mainly diagnosed with mild strokes suggests that robust stroke patients have fairly good and stable post-stroke HRQoL, while post-stroke HRQoL is impaired and continues to deteriorate among patients with in-hospital frailty. This emphasises the importance of a greater focus on frailty in stroke units. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT02650531 ).

OBJECTIVES: To explore factors from the acute phase, and after three and 12 months, associated with level of self-reported physical activity 12 months after a minor ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) score ≤ 3 in persons 70 years or younger. MATERIALS AND METHOD: In this longitudinal cohort study patients were recruited consecutively from two stroke units. Activity level were measured with three sets of questions addressing the average number of frequency (times exercising each week), the average intensity, and duration (the average time), and a sum score was constructed. The association between physical activity 12 months after stroke and sociodemographic factors, NIHSS, body mass index, balance, and neuropsychiatric symptoms were explored using multiple linear regression. RESULTS: This study included 101 patients, with mean age (SD) 55.5 (11.4) years, NIHSS median (Q1, Q3) 0.0 (0.0, 1.0), and 20 % were female. Multiple linear regression analyses showed sick leave status at stroke onset, balance at three and 12 months, and anxiety, depression, apathy, and fatigue at 12 months to be factors associated with physical activity at 12 months after stroke. CONCLUSION: We found that pre-stroke sick leave, post-stroke balance, and neuropsychiatric symptoms were associated with the level of physical activity one year after minor stroke. This might be of importance when giving information about physical activity and deciding about post-stroke follow-up.

OBJECTIVES: We aimed to assess longitudinal changes in MRI measures of brain atrophy and white matter lesions in stroke and transient ischemic attack (TIA) survivors, and explore whether carotid stenosis predicts progression of these changes, assessed by visual rating scales. MATERIALS AND METHODS: All patients with a first-ever stroke or TIA admitted to Bærum Hospital, Norway, in 2007/2008, were invited in the acute phase and followed for seven years. Carotid ultrasound was performed during the hospital stay. Carotid stenosis was defined as ≥50% narrowing of lumen. MRI was performed one and seven years after the index event and analyzed according to the visual rating scales Fazekas scale (0-3), Medial Temporal Lobe Atrophy (MTLA) (0-4) score, and Global Cortical Atrophy (GCA) scale (0-3). Patients with MRI scans at both time points were included in this sub-study. RESULTS: Of 227 patients recruited, 76 had both MRI examinations. Mean age 73.9±10.6, 41% women, and 9% had ≥50% carotid stenosis. Mean Fazekas scale was 1.7±0.9 and 1.8±1.0, mean MTLA score 1.0 ±1.0 and 1.7±1.0, and mean GCA scale score 1.4±0.7 and 1.4±0.6 after one and seven years, respectively. 71% retained the same Fazekas scale score, while 21% showed progression. Deterioration in GCA scale was seen in 20% and increasing MTLA score in 57%. Carotid stenosis was not associated with progression on Fazekas score, MTLA score or GCA scale. CONCLUSIONS: Three out of five showed progression on the MTLA score. Carotid stenosis was not associated with longitudinal change of visual rating scales.

BACKGROUND: Cognitive impairment (CI) with mixed vascular and neurodegenerative pathologies after stroke is common. The role of amyloid pathology in post-stroke CI is unclear. We hypothesize that amyloid deposition, measured with Flutemetamol (18F-Flut) positron emission tomography (PET), is common in seven-year stroke survivors diagnosed with CI and, further, that quantitatively assessed 18F-Flut-PET uptake after 7 years correlates with amyloid-ß peptide (Aß42) levels in cerebrospinal fluid (CSF) at 1 year, and with measures of neurodegeneration and cognition at 7 years post-stroke. METHODS: 208 patients with first-ever stroke or transient Ischemic Attack (TIA) without pre-existing CI were included during 2007 and 2008. At one- and seven-years post-stroke, cognitive status was assessed, and categorized into dementia, mild cognitive impairment or normal. Etiologic sub-classification was based on magnetic resonance imaging (MRI) findings, CSF biomarkers and clinical cognitive profile. At 7 years, patients were offered 18F-Flut-PET, and amyloid-positivity was assessed visually and semi-quantitatively. The associations between 18F-Flut-PET standardized uptake value ratios (SUVr) and measures of neurodegeneration (medial temporal lobe atrophy (MTLA), global cortical atrophy (GCA)) and cognition (Mini-Mental State Exam (MMSE), Trail-making test A (TMT-A)) and CSF Aß42 levels were assessed using linear regression. RESULTS: In total, 111 patients completed 7-year follow-up, and 26 patients agreed to PET imaging, of whom 13 had CSF biomarkers from 1 year. Thirteen out of 26 patients were diagnosed with CI 7 years post-stroke, but only one had visually assessed amyloid positivity. CSF Aß42 levels at 1 year, MTA grade, GCA scale, MMSE score or TMT-A at 7 years did not correlate with 18F-Flut-PET SUVr in this cohort. CONCLUSIONS: Amyloid binding was not common in 7-year stroke survivors diagnosed with CI. Quantitatively assessed, cortical amyloid deposition did not correlate with other measures related to neurodegeneration or cognition. Therefore, amyloid pathology may not be a key mediator of neurodegeneration 7 years post-stroke. TRIAL REGISTRATION: Clinicaltrials.gov (NCT00506818). July 23, 2007.

BACKGROUND AND PURPOSE: Knowledge of the burden and development of post-stroke cognitive impairments (CIs) in the long-term after the first event is limited. We aimed to assess the prevalence of mild CI (MCI) and dementia 7 years after first-ever stroke or transient ischemic attack (TIA), to subclassify the impairments, and to identify predictors for a favorable cognitive outcome. MATERIALS AND METHODS: During 2007 and 2008, 208 patients with first-ever stroke or TIA without preexisting CI were included. After 1 and 7 years, survivors were invited to a follow-up. Transitions of cognitive status from 1 to 7 years were recorded based on the 3 categories dementia, MCI, or none. Etiologic subclassification was based on clinical cognitive profile, magnetic resonance imaging (MRI) findings, and biomarkers at both time points. Favorable outcome was defined as normal cognitive function or MCI after 7 years with exclusion of those who had progression from normal to MCI. RESULTS: Eighty patients died during follow-up, 12 patients refused further participation. After 7 years, 109 completed follow-up of whom 40 (37%) were diagnosed with MCI and 24 (22%) with dementia. Of the 64 patients diagnosed with CI, 9 were subclassified with degenerative cognitive disease, 13 with vascular disease, and 42 had mixed cognitive disease. In all, 65 patients (60%) had a favorable outcome. In multivariable logistic regression analysis, lower age and lower medial temporal lobe atrophy (MTLA) grade on MRI at 12 months were independently associated with a favorable outcome, adjusted OR (95% CI), 0.94 (0.86-0.92), and 0.55 (0.35-0.85), respectively. CONCLUSIONS: Sixty percent of stroke survivors have a favorable cognitive outcome. Lower age and lower MTLA grade on MRI were associated with favorable outcome.

BACKGROUND: Many home-dwelling elderly use medical compression stockings to prevent venous insufficiency, deep venous thrombosis, painful legs and leg ulcers. Assisting users with applying and removing compression stockings demands resources from the home based health services, but the effects are uncertain. This systematic review aims to summarize the effects of preventive use of medical compression stockings for patients with chronic venous insufficiency and swollen legs. METHODS: We conducted a search in six databases (Epistemonikos, Cochrane Database of Systematic Reviews, MEDLINE, Embase, CENTRAL and CINAHL) in March 2018. Randomized controlled trials evaluating the preventive effects of European standard compression stockings class 3 or 2 for elderly with chronic venous insufficiency and swollen legs were included. Primary outcomes were thrombosis, leg ulcers and mobility. Secondary outcomes were other health related outcomes, e.g. pain, compliance. We assessed risk of bias in the included studies and used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool for evaluating the overall quality of evidence. RESULTS: Five randomized controlled trials met the inclusion criteria. Comparing compression stockings class 2 to class 1, meta-analysis showed a reduction in leg ulcer recurrence at 12 months (RR 0.52; 95% CI 0.30 to 0.88). The quality of evidence was assessed as moderate by GRADE. One study (100 participants) did not detect a difference between compression stockings class 3 versus class 2 on ulcer recurrence after six months (RR 0.64; 95% CI 0.20 to 2.03). In another study, patients wearing class 3 compression stockings had lower recurrence risk compared with patients without stockings (RR 0.46; 95% CI 0.27 to 0.76) at six months and (RR 0.43; 95% CI 0.27 to 0.69) at 12 months. We found no difference between class 2 and class 1 stockings on subjective symptoms of chronic venous insufficiency or outcomes of vein thrombosis or mobility. CONCLUSION: Compression stockings class 2 probably reduce the risk of leg ulcer recurrence compared to compression stockings class 1. It is uncertain whether the use of stockings with higher compression grades is associated with a further risk reduction. More randomized controlled trials on vein thrombosis and mobility are needed.

BACKGROUND: Since the first stroke units were established in the 1990s, early mobilisation has formed a key part of the acute treatment. In the context of an updating of national clinical guidelines for stroke, the Norwegian Directorate of Health commissioned the Institute of Public Health to prepare a systematic review of the efficacy and safety of very early mobilisation (within 24 hours) after stroke, compared with current practice, which is early mobilisation (within 48 hours). MATERIAL AND METHOD: We have written a systematic review based on a previous review from the Cochrane Collaboration published in 2009. We performed literature searches for randomised controlled studies in MEDLINE, EMBASE and CENTRAL. RESULTS: Three randomised controlled studies were included. Very early mobilisation showed no statistically significant difference in mortality or functional level compared with early mobilisation. We have very little confidence in the results and are therefore uncertain of the efficacy of the intervention. Very early mobilisation, when prolonged and given regularly, can most likely result in increased mortality and poorer functional level. INTERPRETATION: Early mobilisation is useful for many patients, but very early mobilisation, when frequent and prolonged, may also cause injury. Based on current research, we are uncertain of the optimal time to initiate mobilisation after stroke.

BACKGROUND: Although the most serious consequence of neuronal ischemia is acute neuronal death, mounting evidence suggests similarities between stroke and neurodegenerative disease. Brain atrophy visualized on structural MRI and pathological cerebrospinal fluid (CSF) concentrations of microtubule-associated protein tau (T-tau) and phosphorylated microtubule-associated protein tau indicate neurofibrillary degeneration. We aimed to explore the association between CSF T-tau and brain atrophy 1 year post-stroke. METHODS: We included 210 patients with first-ever ischemic stroke or transitory ischemic attack without pre-existing cognitive impairment. After 12 months, subjects underwent MRI, and CSF biomarkers were assessed. Using SIENAX (part of FSL), ventricular CSF volume and total brain volume were estimated and normalized for subject head size. The association between T-tau as explanatory variable and ventricular and total brain volume as outcome variables were studied using linear regression. RESULTS: One hundred eighty-two patients completed the follow-up. Forty-four had a lumbar puncture. Of these, 31 had their MRI with identical scan parameters. Mean age was 70.2 years (SD 11.7). Ventricular volume on MRI was significantly associated with age, but not with gender. In the multiple regression model, there was a significant association between T-tau and both ventricular (beta 0.44, 95% CI 376.3, 394.9, p = 0.021) and global brain volume (beta -0.50, 95% CI -565.9, -78.3, p = 0.011). There was no significant association between CSF T-tau 1 year post-stroke and baseline volumes. CONCLUSION: T-tau measured 1 year post-stroke is associated with measures of brain atrophy. The findings indicate that acute stroke may enhance or trigger tau-linked neurodegeneration with loss of neurons. TRIAL REGISTRATION: Clinicaltrials.gov NCT00506818 , July 23, 2007.

OBJECTIVES: Depression and anxiety related to stroke are caused by vascular lesions and psychological reactions. Treatment of vascular and modifiable behavioral risk factors reduces the risk of stroke and may also reduce the risk of emotional changes after stroke. We aimed to investigate whether a multifactorial risk factor intervention program in patients with first-ever stroke or transient ischemic attack (TIA) can influence post-stroke anxiety and depressive symptoms in patients one year post-stroke. METHOD: The study population consisted of first-ever stroke and TIA patients allocated in a randomized, evaluator-blinded, controlled trial to care as usual or a structured and multidisciplinary follow-up including intensive treatment of vascular risk. The primary endpoint (cognition) has previously been reported. The secondary endpoint, reported here, was changes in the Hospital Anxiety and Depression Scale (HADS) from baseline to 12-month follow-up. RESULTS: One hundred and ninety-five patients were randomized. The estimated difference between treatment groups, in changes in HADS, from baseline to 12 months was -1.32 (95% confidence interval: -2.61, -0.04; P = 0.044) in favor of the intervention group. One year post-stroke, 4/85 (4.7%) patients in the intervention group and 12/89 (13.5%) in the control group suffered from depression (P = 0.045), while 7/85 (8.2%) patients in the intervention group and 13/89 (14.6%) patients in the control group suffered from anxiety (P = 0.19). CONCLUSION: A structured, multidisciplinary, multifactorial risk factor program including vascular risk factor management may be associated with reduced HADS scores and a lower prevalence of depressive symptoms one year after stroke.

BACKGROUND: The lacunar syndrome is characterized by pure motor, pure sensory, or sensorimotor hemisymptoms without cortical deficits. It may be less predictable for a lacunar infarct (LI) than previously believed. The aims of the present study were to evaluate the diagnostic accuracy of the different lacunar syndromes and investigate factors associated with acute LI on diffusion-weighted imaging (DWI). METHODS: Consecutive patients presenting with an acute lacunar syndrome who were admitted to the stroke unit were enrolled. The patients were examined clinically and underwent magnetic resonance imaging. The sensitivity and specificity of the different lacunar syndromes were assessed using DWI as reference test, and we estimated positive and negative predictive values. Patients were divided into a LI group and a group without LI. Between-group differences were analyzed by χ(2) test, t test, and Mann-Whitney U test, as appropriate. Logistic regression was performed to analyze predictors of LI. Candidate variables were pure motor syndrome, age, gender, hypertension, precerebral or intracerebral stenosis, atrial fibrillation, diabetes, coronary heart disease, and smoking. RESULTS: Eighty-six patients with lacunar syndrome underwent DWI. The positive predictive value of the lacunar syndrome was 65.1% and 75% for the pure motor syndrome. Of the candidate variables, only pure motor syndrome and male gender had significant associations with LI on imaging. CONCLUSIONS: The clinical diagnosis of patients with lacunar syndromes is inaccurate, especially among patients with sensorimotor syndrome.

Introduction: Social anxiety is common and can have far-reaching implications for affected individuals, both on social life and working performance. Usage of virtual reality exposure therapy (VRET) has gained traction. The aim of the present systematic review was to evaluate the effect of stand-alone VRET on social anxiety symptoms. Method: We searched systematically in PubMed, Embase, PSYCinfo, and ERIC in May 2022 for studies with participants with social anxiety symptoms receiving stand-alone VRET. Two reviewers independently selected relevant studies in a two-step procedure, and the risk of bias was assessed. Results: Of 158 hits, 7 studies were selected for full-text reading, 6 were chosen for evaluation, and 5 were included in meta-analyses. VRET resulted in a significantly lower anxiety score in treated individuals with a standard mean difference of -0.82, 95% confidence interval -1.52 to -0.13, compared to controls. Conclusion: Stand-alone VRET may reduce social anxiety symptoms. However, despite promising results, there is still uncertainty as the effect estimate is based on few studies with few participants each and a high risk of bias.

Objective: To evaluate prevalence and factors determining not returning to full-time work 1 year after first-ever mild ischemic stroke. Design: Prospective, observational cohort study with 12-month follow-up. Setting: Stroke units and outpatient clinics at 2 Norwegian hospitals. Participants: We included 84 (N=84) full-time working, cognitively healthy patients aged 70 years or younger who suffered an acute first-ever mild ischemic stroke, defined as National Institutes of Health Stroke Scale (NIHSS) score ≤3 points. Interventions: Not applicable. Main Outcome Measures: Vascular risk factors, sociodemographic factors, stroke localization, and etiology were recorded at inclusion. Cognitive impairment, anxiety, depression, fatigue, and apathy 12 months after stroke were assessed with validated instruments. Logistic regression analyses were performed to find correlates of not returning to full-time employment. Results: Of 78 patients assessed 1 year after stroke, 63 (81%) had returned to work, 47 (60%) to full-time employment status. Modified Rankin scale score >1 (adjusted odds ratio, 12.44 [95% confidence interval, 2.37-65.43], P=.003) at follow-up was significantly associated, and diabetes (adjusted odds ratio, 10.56 [95% confidence interval, 0.98-113.47], P=.052) was borderline significantly associated with not returning to full-time work. Female sex, NIHSS at discharge, anxiety per point on the anxiety scale, depression per point on the depression scale, and fatigue per point on the fatigue scale were significantly associated with not returning to full-time work after 1 year, but these associations were only seen in the unadjusted models. Conclusions: Low functional level that persists 12 months after stroke is related to not returning to full-time work. Patients with diabetes mellitus, female patients, and patients with a higher score on fatigue, anxiety, and depression scales may also be at risk of not returning to full-time work post stroke. Working patients should be followed up with a particular focus on factors determining participation in work and social life.
