Abstract
This study aims to identify WAIS-IV profiles in unilateral ischemic stroke patients in rehabilitation (n = 107) compared to matched controls, to determine if patients demonstrate lateralized cognitive impairment, and to investigate whether aphasia has an additional effect on language and working memory subtests. Analyses revealed impairment in performance of stroke patients relative to controls, while effect of left-hemisphere stroke were large on subtests with language and processing speed demands, and of right-hemisphere stroke on subtests with visuo-spatial and processing speed demands. Aphasia had an additional effect on language, working memory and processing speed subtests. Findings confirm the pattern of cognitive deficits found with older versions of the WAIS and suggest that the WAIS-IV detects cognitive deficits in stroke patients.
Diese Studie analysiert an einer Stichprobe von N = 107 Rehabilitanten mit unilateralen, ischämischen Schlaganfall die Effekte von Lateralisierung und Aphasie auf kognitive Beeinträchtigungen, gemessen mit der WAIS-IV. Im Vergleich zu einer gematchten Kontrollgruppe zeigen die Patienten signifikante Beeinträchtigungen. Hohe Effektstärken ergeben sich bei linkshemisphärischen Schädigungen in Untertests mit Sprach- und Gedächtnisanforderungen und bei rechtshemisphärischen Läsionen in Untertests mit Anforderung an räumlich-visuelle Leistungen und die Verarbeitungsgeschwindigkeit. Eine Aphasie weist einen zusätzlichen Effekt auf Sprach-, Gedächtnis- und Verarbeitungsgeschwindigkeitsleistungen auf. Die Studie bestätigt damit Ergebnisse, die bereits mit vorhergingen Versionen der WAIS gefunden wurden, und zeigt, dass die WAIS-IV zwischen Schlaganfall und Kontrollgruppe trennen kann.
