Primary progressive aphasia
MONDO:0019806Primary progressive aphasia (PPA) is a neurodegenerative disorder, characterized by a primary dissolution of language, with relative sparing of other mental faculties for at least the first 2 years of illness. PPA is recognized as the language variant in the frontotemporal dementia (FTD) spectrum of disorders. PPA can be classified into 3 subtypes based on specific speech and language features: semantic dementia (SD), progressive non-fluent aphasia (PNFA) and logopenic progressive aphasia (lv-PPA).
Also known as: Mesulam syndrome, PPA, primary progressive aphasia syndrome
