Using data from the COMPASS-ND study we investigated associations between hearing loss and hippocampal volume as well as cortical thickness in older adults us polo assn mens sweaters with subjective cognitive decline (SCD), mild cognitive impairment (MCI), and Alzheimer’s dementia (AD).SCD participants with greater pure-tone hearing loss exhibited lower hippocampal volume, but more cortical thickness in the left read more superior temporal gyrus and right pars opercularis.Greater speech-in-noise reception thresholds were associated with lower cortical thickness bilaterally across much of the cortex in AD.The AD group also showed a trend towards worse speech-in-noise thresholds compared to the SCD group.
