Abstract

Two studies explored whether sentence comprehension impairments in Alzheimer's disease (AD) are due to deficits in syntactic processing or memory. Study 1 used a picture-pointing sentence comprehension task tomeasure the final outcome of comprehension in an off-line fashion. Itshowed the comprehension of 30 patients with AD to be impaired, but suggested that the deficits could not be attributed solely to syntacticimpairments. Study 2 investigated the effects of memory on sentence comprehension by comparing off-line (grammaticality judgment) with on-line (cross-modal naming) language processing in 11 AD and 9 control subjects. The results revealed impaired performance in the off-line taskbut normal performance in the on-line task using the same sentences. Performance on the off-line task correlated with independent measures of verbal working memory. These data are used to argue that sentence comprehension impairments are related to verbal working memory deficitsin AD. (C) 1998 Academic Press.
