Hearing loss is often viewed as a stand-alone medical issue. However, there are additional health concerns associated with hearing loss that shouldn’t be ignored. Studies are beginning to show that memory and brain function can both be negatively impacted as a result of hearing loss.

When we think of hearing, our first thought is generally our ears, but in reality, it is the brain that hears. Understanding the brain’s role in quality hearing is key to understanding hearing loss.

Oftentimes, the additional effort dedicated to listening when there is a decrease in hearing ability can cause stress, which in turn may result in decreased memory resources. In essence, one’s brain becomes so taxed from the mere effort of listening, that there is no energy left to remember the information that was taken in.

Here is the core issue: we actually hear with our brain, and not our ears. Our brain’s ability to analyze information heard is impacted by the effort the brain must put forth in order to first decode the actual words heard.

The link between hearing and brain function also suggests connections between hearing loss and dementia. According to multiple John Hopkins studies1, the use of help in preventing dementia. In fact, properly fitted hearing aids can hearing loss can have a greater impact on potential dementia than other health conditions or even genetic diseases.

Additionally, studies2 have shown that those who use effective hearing aids are more socially engaged and possess a more positive outlook on life. The relationships one engages in once hearing loss is treated can be yet another preventative measure when it comes to cognitive abilities, memory, and dementia. A recent study by the Journal of the American Geriatric Society3 shows that there is a greater chance of cognitive decline for those with hearing aids. This is largely due to hearing difficulties who do not use the natural tendency to withdraw from social activities when listening becomes difficult.

One of the best things you can do to preserve your memory and cognitive abilities is to get a hearing test. Be proactive about your hearing. Many hearing evaluations are covered by Medicare or insurance and can help identify any hearing difficulties you may be experiencing.

Help Delay and Even Prevent Cognitive Decline

In order to help delay and even prevent cognitive decline, it is important to understand more about your own hearing and determine if interventions are necessary. In fact, a study* conducted at Columbia
University Medical Center (CUMC) found that older adults whose evaluation revealed the need for hearing aids performed significantly better on cognitive tests than those who needed, but did not use, a hearing aid.

What To Do

  • Have your hearing evaluated regularly after the age of 50. The sooner you address the issue, the less likely you are to suffer cognitive disadvantages. Auditory processing can become more difficult with age and/or untreated hearing loss. It is important to identify hearing problems early on in order to keep the brain pathways strong.
  • Protect your ears. Even if you don’t need hearing aids, there are many ways to keep your ears protected from loud sounds.
  • Lead a healthy lifestyle. Be wise about your overall health. According to Weill Cornell Medical School, it is important to prevent low blood flow, which can harm your inner ear. Exercising, eating well, getting a massage, checking the side effects of your medications, and ceasing to smoke are all steps you can take that can increase health and well being.
