Cognitive Function Differences based on Hemispheric Lesions of First-Ever Ischemic Stroke Patients

Abstract

Ischemic stroke is one of stroke subtype often correlated with disturbance of cognitive function. We conduct an observational study with cross-sectional design of 70 ischemic stroke patients. Objective of this study is to evaluate cognitive differences based on hemispheric lateralization lesions. We used Montreal Cognitive Assessment – Indonesian version (MoCA-Ina) to assess cognitive function resulting on 70 patients, consist of 48 subjects (68.57 %) of left hemispheric stroke and 22 subjects (31.43%) of right hemispheric stroke. As much as 68 subjects (97.14 %) are categorized as having cognitive disturbance. Mean differences of MoCA-Ina was assessed using Mann-Whitney test resulting no significant differences between left vs right hemisphere groups (18.94 + 3.26 vs 19.82 + 3.13; p= 0.320). Further study would warrant lesions lateralizations could affects cognitive performance of ischemic stroke patients.
