Immune-Inflammatory Biomarkers in Predicting Early Cognitive Impairment in Adults With Acute Basal Ganglionic Stroke

Sponsor: Assiut University

Summary

Post-stroke cognitive impairment (PSCI) is a common and disabling complication that affects memory, thinking, and daily functioning after a stroke. The immune-inflammatory response triggered during an acute stroke is believed to contribute to secondary brain injury and cognitive decline. Routine, low-cost blood tests that assess systemic inflammation, specifically the neutrophil-to-lymphocyte ratio (NLR), globulin-to-lymphocyte ratio (GLR), C-reactive protein-to-lymphocyte ratio (CLR), and lymphocyte-to-monocyte ratio (LMR), may serve as useful early indicators of cognitive risk. The purpose of this observational study is to evaluate whether these inflammatory blood markers, measured during the acute hospital phase, can independently predict early-onset cognitive impairment in adult patients aged 18 to 59 years with acute basal ganglionic stroke (ischemic or primary hemorrhagic). Participants admitted within 72 hours of symptom onset will undergo standard clinical assessments, stroke severity evaluation using the National Institutes of Health Stroke Scale (NIHSS), brain neuroimaging (CT or MRI), and routine blood testing between 24 and 72 hours post-admission. At 3 months post-stroke, participants will complete a cognitive evaluation using the Arabic-validated Montreal Cognitive Assessment (MoCA). Identifying accessible admission biomarkers could help healthcare providers recognize patients at high risk of cognitive impairment early, enabling timely monitoring and early referral for cognitive rehabilitation.
