Frequency of domain-specific cognitive impairment in sub-acute and chronic stroke

摘要: BACKGROUND Functional contributions of cognitive impairment may vary by domain and severity. OBJECTIVE (1) To characterize frequency after stroke severity (mild: -1.5 ≤ z-score < -2; severe: Z -2) time (sub-acute: 90d; chronic: 90d-2yrs); (2) assess the association with function in chronic stroke. METHODS Cognitive was characterized among 215 people sub-acute or (66.8 years, 43.3% female). Z-scores were determined from normative data. Function defined as number IADLs minimally independent. RESULTS 76.3% 67.3% participants had ≥ 1 (p-for-difference = 0.09). Severe most common psychomotor speed 53.5%; 33.7%). Impairment executive 39.5%; 30.7%) but usually mild. speed, visuospatial function, language any memory associated IADL (p 0.03). CONCLUSIONS Mild is not functional disability. so should be a focus screening rehabilitation post-stroke.
