Hearing Loss Linked to Dementia and Mental Health Issues

Hearing loss can be frustrating but it can also cause significant mental health issues such as depression, anxiety, and anger. Research has revealed that there is also an increased risk for cognitive decline and dementia. According to the National Institute on Deafness and Other Communication Disorders, by ages 65 to 74, 25% of the population will suffer hearing loss. By the age of 75 and above, 50% will have a hearing deficit, including tinnitus, or ringing in the ears

Years of study have resulted in scientific evidence that confirms the connection between hearing loss, cognitive decline, and brain function. A 2011 study performed by hearing experts at Johns Hopkins University followed 639 people for 12 years. The results showed that those with severe hearing loss were five times more likely to develop dementia than those with normal hearing. For those with moderate hearing loss, the risk was three times greater, while those with mild impairment were twice as likely. Researchers also determined that cognitive decline occurs 30-40% faster in those with hearing loss. A 2014 study in Neuroimage found that hearing impairment shrinks the brain.

There is also an increased risk for emotional and mental health issues among those with hearing problems. Family gatherings and day-to-day conversations may leave the hearing impaired feeling left out, resulting in depression. A 2014 study found that 19% of adults with hearing loss experience mild symptoms of depression while more than 11% struggle with moderate-to-severe depressive symptoms.

Hearing loss can be the source of insecurities, causing stress and anxiety. Many worry that they will lose their hearing completely, lose their job, or wonder if they will be able to function safely in life if, for instance, they can’t hear a smoke alarm. This can cause irritability, frustration, and feelings of loneliness as the hearing impaired retreat from family and friends because of the embarrassment of having to constantly ask people to repeat themselves.

It’s important to address hearing loss as soon as it’s noticed. Since the condition is progressive, if left untreated it may lead to an increased risk for mental health problems and cognitive decline.
