We assessed phoneme discrimination in patients with PPA (semantic, nonfluent\/agrammatic, and logopenic variants) and typical Alzheimer\u2019s disease, relative to healthy age\u2010matched participants. The lvPPA group performed significantly worse than all other groups apart from tAD, after adjusting for auditory verbal working memory. In the combined PPA cohort, voxel\u2010based morphometry correlated phonemic discrimination score with grey matter in left angular gyrus. Our findings suggest that impaired phonemic discrimination may help differentiate lvPPA from other PPA subtypes, with important diagnostic and management implications.<\/jats:p>","DOI":"10.1002\/acn3.51101","type":"journal-article","created":{"date-parts":[[2020,6,18]],"date-time":"2020-06-18T18:08:12Z","timestamp":1592503692000},"page":"1252-1257","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Impaired phonemic discrimination in logopenic variant primary progressive aphasia"],"prefix":"10.1002","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4265-7997","authenticated-orcid":false,"given":"Jeremy C.
