Researchers have found that even the earliest stage of hearing loss – when hearing is still considered normal (0-25dB) – is linked to cognitive decline. Most people with hearing loss believe they can go about their lives just fine without treatment, and maybe some can, but hearing loss is not benign. It has been linked to social isolation, depression, cognitive decline, diabetes, dementia, and other health problems. Hearing loss should be treated, and the earlier, the better. Studies show hearing aids can slow cognitive decline in older people with age-related hearing loss.
