Primary progressive aphasia (PPA) is a rare neurological condition that affects an individual’s ability to communicate. PPA is a syndrome characterized by a ‘progressive worsening of language with preservation of the activities of daily living and evidence of relatively normal non-verbal abilities on neuropsychological testing’. It commonly appears initially as a disorder of speaking (an articulatory problem) progressing to nearly total inability to speak in its most severe stage, while comprehension remains relatively preserved. This chapter provides an overview of the characteristic features of PPA, its classification, assessment, and rehabilitation options.
