Post‐stroke dementia and its determinant factors among Ethiopian stroke survivors: A cross‐sectional study

Abstract

AbstractBackgroundStroke and dementia convene risks for each other and share some of the same, largely modifiable, risk factors.MethodAdult stroke survivors, who visited the outpatient stroke clinic in Tikur Anbessa Specialized Teaching Hospital in Addis Ababa University, Ethiopia was assessed for cognitive decline. Beside Montreal Cognitive Assessment‐Basic (MOCA‐B) tool, functional recovery and depression were measured using modified Rankin Scale (mRS) and Patient Health Questionnaire (PHQ‐9).ResultFrom 67 stroke survivors (mean age: 52.1 ± 12.7 years, 40.3 % female, 25.3% illiterate, rural dwellers 32.8%, 37.3% stoke onset < 45‐year), 68.7% had cognitive impairment in at least one domain and 25.3% had dementia. Hospitalization [OR = 0.22 (0.06 ‐0.74)], right hemisphere stroke location [OR = 0.21 (0.06‐0.77)] and poor function recovery with mRS ³3 [OR = 1.4 (1.06‐1.74)] were independently associated with post stroke cognitive impairment and dementia.ConclusionThe frequency of post stroke dementia was high in Ethiopia and poor functional recovery negatively impact cognitive outcome.
