Abstract

In non-fluent aphasia, oral expression is often agrammatic, i.e. grammatically incomplete and/or incorrect. By contrast, expression in fluent aphasia usually appears grammatical, albeit with disruptions in content. Despite this persistent impression, errors of sentence structure and morphology do occur in fluent aphasia, although they take the form of substitutions rather than omissions. This has been called ‘paragrammatism’. The underlying deficit giving rise to paragrammatism remains poorly understood, however. In this study, the lexical and grammatical abilities of an individual with paragrammatism and an individual with agrammatism are compared. The relationship between the two disorders, and their possible underpinnings, are discussed.
