Primary progressive aphasia (PPA) is a group of syndromes due to different neuropathological substates, providing a window into language neurobiology that is complementary to the traditional investigation of language disorders due to stroke and to neuroimaging studies in healthy subjects. The psycholinguistic and neuropsychological analysis of errors in production tasks and of performance in language comprehension in PPA and in other neurodegenerative disorders has provided important insights into the mechanisms of progressive language dysfunction and its neurobiological underpinning. The different syndromes of PPA can be considered as system disorders, reflecting the progressive, graded  involvement of the main brain networks subserving language function: the non-fluent/agrammatic variant mainly affecting the motor speech /morphosyntactic aspects of linguistic organization; the semantic variant the dysfunction of lexical/semantic processing; and the logopenic/phonological variant the lexical/phonological network.
