Abstract
Adverse non-motor outcomes are common after stroke, yet their true prevalence and prognosis remain uncertain, partly due to substantial methodological heterogeneity across studies. We aim to undertake a comprehensive synthesis of the available evidence on adverse non-motor outcomes after stroke. First, we aim to examine prevalence across study settings (hospital-based versus population-based cohorts) and to evaluate the influence of outcome definitions, measurement instruments (validated versus non-validated), stroke type (ischaemic stroke, intracerebral haemorrhage, or mixed), and duration of follow-up. Second, we aim to identify study-level characteristics associated with adverse outcomes.
We searched PubMed, MEDLINE, EMBASE, Scopus, Web of Science, and PsycINFO via Ovid (1st January 1999 - 30th November 2025) for prospective cohorts reporting 11 non-motor outcomes: anxiety, depression, apathy, fatigue, sleep disturbance, social participation, pain, bladder, bowel, and sexual dysfunction. Pooled prevalence according to study setting (hospital versus population) was estimated using random-effects models; outcome definitions and measures were synthesised using descriptive statistics, and meta-regression analysis was used to identify associated factors. The quality of all included studies was assessed with the Newcastle-Ottawa Scale.
A total of 357 prospective cohort studies, (247 541 participants; mean age 64 years; 247 male-predominant studies) were included, with a follow-up between 30 days to 10 years after stroke with median follow-up 6 months [IQR 3-12]. Half of the studies were hospital based 181/352 (51%). Of the included studies, 195 (55%) included participants with ischaemic stroke, 148 (42%) included participants with ischaemic stroke or intracerebral haemorrhage, while only 10 (3%) included participants with intracerebral haemorrhage. Across all analysis heterogeneity ranged I2 41%-99%. We found no significant differences in the prevalence of adverse non-motor outcomes between hospital versus population settings, except, bowel dysfunction was more frequently reported in population-based studies (61%, 95% Cl 54%-67% vs 47%, 95% Cl 37%-58%, p=0.005). Non-validated outcome measures were used in 156/352 studies (44.3%). Studies using non-validated outcome measures showed higher pooled prevalence of anxiety (34%, 95% Cl 29%-40%, vs 25%, 95% Cl 20%-33%, p<0.001), apathy (32%, 95% Cl 27%-36, vs 22%, 95% 13%-41%, p=0.005), sleep disturbance (62%, 95% Cl 54%-73%, vs 51%, 95% Cl 44%-58%, p<0.001), and bowel dysfunction (56%, 95% Cl 43%-69% vs. 49%, 95% Cl 38%-60%, p=0.027). Majority of studies 207/352 (59%), were conducted within 30 days to 6 months after stroke, whereas only 41/352 (12%) examined non-motor outcomes beyond 2 years post-stroke. Older age (>60 years), stroke due to ICH, and use of non-validated outcome measures were significantly associated with a higher prevalence of adverse non-motor outcomes across multiple domains.
Non-motor outcomes are highly prevalent after stroke in hospital and population settings. However, we found methodological limitations across included studies, including limited evidence on non-motor outcomes after ICH, poor characterisation of stroke type, frequent use of non-validated outcome measures, and few studies assessing outcomes beyond two years after stroke. Our findings indicate an urgent need for long-term, methodologically rigorous studies of non-motor outcomes after stroke to enable consistent assessment, inform life after stroke pathways, and improve clinical care.
