How the Brain is Affected by Hearing Loss

How the Brain is Affected by Hearing Loss

March is Brain Health Awareness Month!

The human brain is made up of approximately one hundred billion neurons. Communication between these neurons is essential to understanding everything we see, think and do. So, what happens to our brain as we age and our senses start to fail? 

When our hearing starts to fail

When hearing loss occurs, the part of the brain devoted to hearing can become reorganized, or reassigned to other functions.
A study done at the University of Colorado’s Department of Speech Language and Hearing Science, assessed adults and children with varying degrees of hearing loss to measure how the brain responded to sound stimulation.
What they found is that when hearing loss occurs, the areas of the brain that manage other senses, like vision and touch, take over the areas of the brain that normally process hearing. Essentially the brain compensates for the loss and adapts by rewiring itself. The brain is a “use it or lose it” organ, and hearing loss should be addressed as soon as it’s identified.

Early intervention

Early diagnosis and intervention to aid in hearing loss can help maintain cognitive function. Hearing loss can impact the brain’s ability to process sound, which can affect a person’s ability to understand speech. Even mild hearing loss can cause changes in the brain, so hearing screenings for all ages are important to protect against reorganization of the brain.

The Link Between Hearing Loss, Cardiovascular Disease and Diabetes

The Link Between Hearing Loss, Cardiovascular Disease and Diabetes

The Link Between Hearing Loss, Cardiovascular Disease and Diabetes


A healthy heart not only helps you live longer but can help you hear longer too. Did you know that hearing loss is directly linked to your overall health, especially your cardiovascular health?


Research has recently proved that hearing loss is linked to cardiovascular disease and diabetes.


Here’s what you need to know…


The link between the heart and ears

New research reveals that a healthy heart is the key to healthy hearing. The inner ear is sensitive to changes in blood flow and compromised cardiovascular health can harm the peripheral and central auditory systems. Inadequate blood flow and trauma to the blood vessels of the inner ear can cause hearing loss.


On the flipside, a healthy cardiovascular system can have a positive impact on hearing.


Diabetes and hearing loss

Hearing loss is twice as common in people with diabetes compared to those who do not have diabetes. This is because hearing depends on small blood vessels and nerves in the inner ear. Researchers believe that over time, high blood glucose levels can damage these vessels and nerves, diminishing the ability to hear.


Other stats:


  • Women with a history of heart attack are 2.7 times more likely to have impaired cochlear function
  • Higher BMI and larger waist circumference in women is associated with an increased risk of hearing loss, and higher physical activity is associated with reduced risk of hearing loss in women
  • An individual’s risk of hearing loss increases by 15.1% if he or she is a persistent smoker

The best method of treatment for all disease, including heart disease, diabetes and hearing loss is prevention. All adults over the age of 55 years should be referred for a baseline diagnostic audiological evaluation.
