This cross-sectional study of 100 acute ischemic stroke patients examined whether signal intensity in normal-appearing white matter on FLAIR MRI correlates with leukoaraiosis burden. Results showed that white matter signal intensity increased near leukoaraiosis borders and was independently associated with leukoaraiosis volume, suggesting structural abnormalities extend into apparently normal brain tissue.
This retrospective study of 970 stroke/TIA patients found that elevated sST2 levels independently predicted atrial fibrillation detection after stroke (AFDAS), with sST2 showing superior predictive value (AUC 0.815) compared to conventional risk factors. Adding sST2 to a conventional risk model significantly improved prediction accuracy for AFDAS in acute stroke patients.
A clinical trial compared the effectiveness of the Bimanual Arm Trainer device with standard occupational therapy in 27 stroke patients with upper extremity dysfunction. Both treatment groups showed significant improvements in arm function, with no statistically significant difference between the intervention and control groups, suggesting device-assisted therapy may provide comparable benefits to traditional therapy.
This systematic review synthesizes evidence from four studies to estimate the prevalence of familial hypercholesterolemia (FH) in stroke and TIA patients, finding a pooled prevalence of 0.96% overall and 2.89% in large artery atherosclerosis strokes. The authors acknowledge significant heterogeneity between studies and conclude that while evidence suggests FH may be relevant to cerebrovascular disease beyond cardiology, more research is needed for firm quantitative conclusions.
Patients with autoimmune rheumatic diseases (such as lupus and vasculitis) have significantly elevated stroke risk 1.3-2.5 times higher than the general population, often occurring at younger ages due to systemic inflammation and immune-mediated vascular injury. This review synthesizes evidence on stroke pathophysiology, prevention strategies, and post-stroke rehabilitation outcomes specific to rheumatologic populations.
