Subjective hearing loss is not associated with significantly different dementia neuropathology, a new study found. Researchers evaluated for differences in dementia neuropathology between subjective normal hearing and hearing loss participants, as well as individuals who wore hearing aids. They found:
- 273 individuals were included in the analysis.
- No significant difference demonstrated in Alzheimer’s disease (AD) neuropathology or pathologic state.
- No significant difference was observed in neuropathology of other major dementia types.
- Individuals with hearing aids had a lower prevalence of clinical dementia with no significant difference in dementia neuropathology.
