It should be common sense that untreated hearing loss and the associated isolation would exacerbate cognitive decline, but a study was completed on behalf of the SENSE‐Cog WP1 group and reported in the Journal of the American Geriatrics Society, Vol. 66, Issue 6, June 2018 provides backup data. The conclusion: “Hearing aids may have a mitigating effect on trajectories of cognitive decline in later life. Providing hearing aids or other rehabilitative services for hearing impairment much earlier in the course of hearing impairment may stem the worldwide rise of dementia.”
Note that it also says that addressing this earlier provides the best effect. Just another reason proper hearing health care is important to your quality of life. Don’t forget that changes in your hearing can also be indicators of other issues. As your Audiologist, I can help with these issues, and if necessary, direct you to other health care professionals with advanced skills in these areas.
