Abstract

ABSTRACT: Using an anagram task, we investigated longitudinal syntactic production by individuals with semantic variant primary progressive aphasia (svPPA) and non-fluent variant PPA (nfvPPA), compared to controls. The accuracy of the production of active and passive, and reversible and non-reversible sentences, as well as of wh - questions was compared across the three groups. Results showed a different pattern of syntactic impairment across the two patient groups. The nfvPPA group showed difficulty with wh- questions at Time 1 and impairment with the passive structure approximately one year later, at Time 2. Surprisingly, the svPPA group also showed difficulty with wh- questions from Time 1, but still no difficulty on passive sentences, two years later, at Time 3. Neither group had difficulty with reversibility. The results of the nfvPPA patients were as expected, and the results of the svPPA patients suggest that this group may exhibit a greater syntactic impairment than is typically recognized.
