Progressive non-fluent aphasia (PNFA) is a form of frontotemporal dementia (FTD) characterized by agrammatism, laborious speech, alexia, and agraphia, often accompanied by apraxia of speech (AOS). Language comprehension remains relatively preserved. PNFA is one of three clinical syndromes associated with frontotemporal lobar degeneration, with an insidious onset of language deficits over time. The disorder primarily affects the left hemisphere, leading to expressive language deficits and potential disruptions in comprehending complex language.
