Cognitive Decline

Research has long pointed to links between common comorbidities such as hearing loss and decreased brain functioning over time, but some of the statistics may surprise you:

  • On average, seniors with hearing loss experience significantly reduced cognitive function 3.2 years before their normal-hearing counterparts.
  • Hearing-impaired seniors experience thinking and memory recall issues 30 to 40 percent faster than their normal-hearing counterparts.
  • Older adults with a hearing disability may lose over a cubic centimeter of brain tissue annually beyond normal shrinkage.
  • Those with hearing loss are two, three, or nearly five times as likely to develop dementia, depending on the severity of their hearing impairment.

The causal relationship between hearing loss and cognitive decline isn’t completely clear, but some research suggests that addressing hearing loss could cut dementia cases by a third.
