Abstract
Abstract Objective The semantic, logopenic, and nonfluent/aggramatic variants of primary progressive aphasia (PPA) have distinct clinical profiles. However, much overlap exists and many questions remain regarding the nature of language impairments in each variant. This case study seeks to contribute to our understanding of the neuropsychological profile, syntactic, and phonological processes involved in logopenic variant PPA (lvPPA). Method The current case study was of a 66-year old female who gradually developed symptoms consistent with lvPPA during the prior four-year period, with marked worsening in the last few months. A collateral informant indicated that she was independent for basic and advanced activities of daily living. Brain/head imaging had not been conducted; medical history was unremarkable. Results Speech was notable for frequent pauses due to word-finding difficulty, circumlocution, and impaired naming, repetition, and verbal abstraction; fluency and comprehension were intact. Test data revealed significant impairments in tasks mediated by language including verbal processing speed, semantic knowledge, phonemic and semantic fluency, verbal learning and memory, verbal set-shifting, and judgment. Comprehension, non-verbal attention and processing speed, recognition for visual information, and performance on tasks of non-verbal executive functioning were intact. Depression and anxiety were denied. Conclusions Findings were notable for prominent language deficits, with preserved articulation, basic comprehension, and no evidence of visual agnosia. Her progression of symptoms, medical history, and test data were not consistent with a typical Alzheimer’s or vascular process, but were most consistent with lvPPA. Neurology consultation, MRI brain with volumetric analysis, and speech therapy were recommended.
