ABSTRACT NUMBER: ESOC2026OT194 COGNITIVE IMPAIRMENT AFTER PEDIATRIC STROKE: LEFT AND RIGHT HEMISPHERE

Abstract Background and aims Background Cognitive deficits after pediatric stroke are frequently underrecognized. Differences between left- and right-hemispheric lesions require detailed analysis. Methods Objective To compare the frequency and structure of cognitive impairment in ischemic and hemorrhagic stroke involving the left and right hemispheres. Results Materials and Methods Twenty-three children aged 1–17 years were examined: 12 with left-hemispheric and 11 with right-hemispheric lesions. Ischemic stroke occurred in 15 cases (65%), hemorrhagic in 8 (35%). MRI, EEG, and neuropsychological testing were performed. Conclusions Results Cognitive impairment was identified in 17 children (74%): mild in 5 (22%), moderate in 8 (35%), and severe in 4 (17%). Deficits were more frequent after hemorrhagic stroke (87%) than ischemic stroke (67%). Conflict of interest
