Hardy CJD, et al. - In this cross-sectional single-center study, researchers evaluated peripheral hearing function in nonfluent/agrammatic variant primary progressive aphasia (nfvPPA) [characterized as a disorder of language production] individuals vs healthy older people and Alzheimer's disease (AD) patients. For this investigation, they studied 19 patients with nfvPPA, 20 patients with AD and 34 control participants. Investigators found that nfvPPA patients performed worse on pure-tone audiometry than healthy older patients or AD patients and the difference was not due to age or general disease factors. Additionally, nfvPPA cases were linked to increased functional interaural audiometric asymmetry. These outcomes suggest conjoint peripheral afferent and more central regulatory auditory dysfunction in nfvPPA people.
