AD/PD 2023 | Hearing loss and dementia

The two most recent iterations of the Lancet Commission on dementia prevention, intervention, and care have flagged hearing loss as a key modifying factor for dementia prevention. M. Florencia Iulita, PhD, Altoida, Inc., describes the research looking into the epidemiological and biological associations between hearing loss and cognitive impairment, and potential explanations for these links. Studies done with MRI have found that those with hearing loss have reduced volumes of the hippocampus and entorhinal cortex, which are key areas for memory and are also affected in Alzheimer’s disease. Increased social isolation resulting from hearing loss may also contribute to its impact of cognition. There is still more research needed to understand these associations and how to tackle them. This interview took place at the AD/PD™ 2023 congress in Gothenburg, Sweden.
