Language training for oral and written naming impairment in primary progressive aphasia: a review
Abstract Background Primary progressive aphasia (PPA) is a neurodegenerative disorder characterized by a gradual, insidious and progressive loss of language abilities, with naming difficulties being an early and persistent impairment common to all three variants. In the absence of effective pharmaco...
