Hear Well – Be Well
By Catherine M Marino, AuD

A decline in hearing has often been considered an inevitable part of the aging process. However, we now have sufficient evidence to know that hearing loss should no longer be considered a benign condition to be passively dealt with. In fact, the consequences of untreated hearing loss can have a far reaching devastating impact on health. Consider the following correlations:
The Heart and Hearing Connection
Studies have shown that a healthy cardiovascular system has a positive effect on hearing. A higher level of physical activity is associated with a lower risk of hearing loss in women as determined by a recent study out of Brigham and Women’s Hospital. In contrast, impaired cardiovascular health negatively impacts hearing since the inner ear is very sensitive to reduced blood flow and blood vessel trauma. A low frequency hearing loss may, in fact, be an early warning sign of cardiovascular disease.
Diabetes and Hearing
Adults with Type 2 diabetes have twice the risk factor for developing hearing loss due to the damage caused by the disease to the inner ear. This correlation highlights the need for regular hearing checks. The earlier a hearing loss is diagnosed, the more effective hearing treatment options are likely to be.
Hearing loss is also related to an increased risk of falling if left untreated. People who do not hear well may lack good awareness of their overall environment, thus increasing the potential to trip and fall. Reduced sensory input also increases the cognitive demands on the person who is trying to maintain balance and gait. In addition, hearing disorders may include vestibular dysfunction leading to poor balance.
Hearing Loss and Dementia
Multiple studies have indicated that untreated hearing loss can affect cognitive brain function and is associated with early onset of dementia in older people. A 2011 study at the University of Pennsylvania concluded that a decline “in hearing abilities may accelerate gray matter atrophy and increase the listening effort necessary to comprehend speech.” Could improved hearing then decrease the chance of developing dementia? The conclusion of the study was that “Hearing aids may not only improve hearing but preserve the brain.” Several recent studies have concluded that early diagnosis and treatment of hearing loss slows the progression of dementia and Alzheimer’s disease.
Hearing in the Workplace
The Better Hearing Institute evaluated the impact of untreated hearing loss on family income. Their study linked untreated hearing loss with “reduced earnings, increased workplace absenteeism, and lower workplace productivity, as well as depression, anxiety, and cognitive decline.”
Cancer Treatments and Hearing
Certain chemotherapy medications or radiation therapy can cause damage to the ears and therefore result in temporary or permanent hearing loss, tinnitus and/or balance disorders. This is something that patient and physician should discuss so that the patient can be aware of the potential risks. A hearing-monitoring program could then be put into place as part of the treatment process and thus relieve potential anxiety and prompt timely treatment.
The Importance of Audiological Evaluation
Hearing and good health go together. If someone suspects hearing loss, an audiological evaluation can help the physician determine other health conditions. Prompt treatment of hearing loss can also help prevent other undesirable complications; such as falling, dementia and depression.
