Brain shrinkage — When the “hearing” section of the brain grows inactive, it results in tissue loss and changes in brain structure—creating the first link between hearing loss and Alzheimer's disease.What type of hearing loss is associated with aging?
Presbycusis, or age-related hearing loss, comes on gradually as a person gets older. It seems to run in families and may occur because of changes in the inner ear and auditory nerve.

What happens if hearing loss is not treated?
Untreated hearing loss and cognitive declineWhen your ability to hear declines, your brain receives less stimulation than it typically would because it's not working to identify different sounds and nuances. Over time, this lack of exercise for your brain can lead to memory loss or even dementia.
Does hearing loss cause cognitive decline?
As we age, connections between cells in the brain are damaged, or some cells are lost—a process that has scarily been called “brain atrophy” or simply “cognitive decline.” And it's quite clear that hearing loss, at the very least, puts you at increased risk of cognitive impairment as you get older.Can hearing loss cause confusion?
