Hemispheric Features of Cognitive and Emotional Disorders in Patients in the Early Recovery Period of Ischemic Stroke

V.R. Herasymchuk, V.A. Hryb

Abstract


The dependence of the nature and degree of poststroke cognitive and emotional disorders on the process localization was studied. In left-hemispheric stroke (LHS), higher incidence of cognitive impairment was observed (80.5 % according to MMSE, the average score 23.88 ± 0.22) compared to right-hemispheric stroke (RHS) (70.3 % by MMSE, the average score 24.65 ± 0.31) (р < 0.05). Impairments of speech functions, attention and memory were characteristic of left-hemispheric lesions, and mainly memory and attention disorders — of right-hemispheric ones. In the emotional sphere of patients with RHS, manifestations of both depressive (56.8 % according to HADS, the average score of 12.23 ± 0.28) and anxiety syndrome (37.8 %, the average 9.68 ± 0.16) were detected more often. In case of LHS, depression was manifested in 34.1 % cases (the average 8.64 ± 0.20). The combination of anxiety and depressive syndromes was observed in 14.6 % cases with LHS and in 35.1 % — with RHS. Also significantly higher levels of personal and situational anxiety were detected in patients with RHS (р < 0.05). Early diagnosis of these disorders and consideration of stroke lateralization when choosing drug therapy could increase the efficacy of rehabilitation in the early recovery period of ischemic stroke and improve patients’ quality of life.
