Syntactic and semantic abilities were compared in 12 patients with mild to moderate dementia of the Alzheimer-Type (DAT) and matched controls. In Experiment 1A, performance on naming, word-picture matching, probe verification, and syntactic comprehension was assessed. Experiment 1B tested subjects' ability to use syntactic, semantic, and sentence contexts to choose the correct pronunciation of homographs and the correct spelling of homophones. Group data and individual patterns were reported. The main results revealed that: (1) all patients showed syntactic and semantic deficits; (2) patients were better able to use sentence contexts than syntactic or semantic contexts in isolation; syntax was not significantly different from semantics. The discussion addressed the concept of dissociation between language components, as well as the heterogeneous clinical presentation of DAT.
