Auditory deprivation occurs
when your brain is deprived of sound
, such as from untreated hearing loss. Over time, your brain loses the ability to process sound. If left untreated, the parts of the brain normally responsible for hearing get “reassigned” to other tasks. Those parts also tend to shrink or atrophy.

Conclusions.
Nonverbal intelligence is adversely affected by bilateral hearing loss
, even at mild hearing loss levels. Social and economic well being appear compromised in individuals with lower nonverbal intelligence test scores.
What part of the brain is affected by hearing?
Auditory information is analyzed by multiple brain centers as it flows to
the superior temporal gyrus, or auditory cortex
, the part of the brain involved in perceiving sound. In the auditory cortex, adjacent neurons tend to respond to tones of similar frequency.
How does hearing affect cognitive function?
Additionally, a 2021 study published by the Journal of Neurology found that hearing loss in the general population is associated with lower baseline levels of cognitive function and
decreased performance on memory tests over time
—although more research is needed before scientists can definitively name hearing loss as a …
Can poor hearing affect memory?
Even relatively mild hearing loss can cause
cognitive overload
, which means people can experience hearing-related memory loss without having moderate or severe hearing problems. In fact, you may notice your memory loss before you’re aware of any reduction in your hearing function.
What organs are responsible for hearing?
The inner ear consists of a spiral shaped structure known as the
cochlea
(means snail-shell). Within the cochlea sits the organ of hearing where we have thousands of tiny cells, known as hair cells. The hair cells are stimulated and send messages to the auditory nerve.
What happens if you ignore hearing loss?

cognitive dysfunction
, particularly dementia, control of attention, and working memory.
Does hearing loss cause Alzheimer’s?
Individuals with moderate to severe hearing loss are up to 5 times as likely to develop dementia. According to several major studies, older adults with hearing loss—especially men—
are more likely to develop Alzheimer’s disease
and dementia, compared to those with normal hearing.
Can loss of hearing lead to dementia?
In a study that tracked 639 adults for nearly 12 years, Johns Hopkins expert Frank Lin, M.D., Ph. D, and his colleagues found that
mild hearing loss doubled dementia risk
. Moderate loss tripled risk, and people with a severe hearing impairment were five times more likely to develop dementia.
Can deafness lead to dementia?
In a study that tracked 639 adults for nearly 12 years, Johns Hopkins expert Frank Lin, M.D., Ph. D, and his colleagues found that
mild hearing loss doubled dementia risk
. Moderate loss tripled risk, and people with a severe hearing impairment were five times more likely to develop dementia.
Why is hearing loss a risk factor for dementia?
Hearing loss increases the cognitive load, diverting cognitive resources to auditory processing at the expense of other cognitive processes such as working memory.
