Untreated hearing loss can increase the risk for dementia by as much as 50%, according to a 2019 study published in the Journal of the American Medical Association. Adults with mild hearing loss are twice as likely to develop dementia compared to those with normal hearing. Those with moderate hearing loss are three times more likely, and individuals with severe hearing loss face a fivefold increase in risk.
So, how does hearing loss impact brain function?
Four Key Ways Hearing Loss Can Lead to Cognitive Decline
According to neurologists and experts in cognitive hearing science, undiagnosed or untreated hearing loss may contribute to dementia through several mechanisms:
- Physiological Stressors
Conditions like high blood pressure, anxiety, and increased stress can accompany hearing difficulties and contribute to cognitive strain. - Cognitive Overload
Constantly straining to hear and understand speech causes listening fatigue and places a heavy burden on the brain. Many individuals unconsciously compensate by reading lips, asking for repetition, or turning on closed captions—a sign that hearing loss may be affecting daily life. - Brain Structure Changes
Lack of auditory stimulation can lead to brain atrophy in areas responsible for processing sound and speech. Over time, these changes may weaken memory, attention, and comprehension skills. - Social Isolation
Avoiding group conversations or noisy environments is common among the hearing impaired, but this isolation is also a known risk factor for cognitive decline. Hearing loss treatment can help individuals stay socially connected and mentally engaged.
