Abstract

I have introduced primary progressive aphasia (PPA) with regard to frontotemporal lobar degeneration (FTLD) and evaluated the following elementary language symptoms for its diagnosis: agrammatism in speech production, apraxia of speech, phonemic paraphasia, naming impairment, impairment of single-word comprehension, and repetition. Furthermore, I have described the clinical symptoms, causative lesions, and pathological findings of three PPA variants —nonfluent/agrammatic, semantic, and logopenic PPA— according to the criteria proposed by Gorno-Tempni et al. (2011).
