The Link between Dementia and Hearing Loss

Did you know there is a link between hearing loss and dementia? A study by Dr. Frank Lin from Johns Hopkins University revealed some startling conclusions. It was found that in adults over 60 years, the more severe the hearing loss, the greater the risk of dementia, including Alzheimer’s disease. The threshold for increased risk of dementia, including Alzheimer’s is a loss of 25 dB, with each additional 10 dB loss of hearing, increasing the risk further. This analysis of data was from a long running study of over 600 people; other studies have shown similar results. Although the data highlights this link, further research is needed to look at the possible causes. There are a number of theories, one of which is that hearing loss impacts on the sufferer’s self-confidence and can lead to a less frequent participation in social activities. A slow withdrawal from clubs and social events leads to isolation and loneliness, which in turn means less mental stimulation. Understanding these factors is of vital importance because it could provide a possible means to decrease the incidence of devastating conditions such as dementia. Interestingly, once hearing loss is suspected, there is a positive benefit in helping the sufferer overcome the problem with the use of hearing devices. This enables the wearer to stay connected with friends and family and continue to participate in social events. They provide vital mental stimulation, which is just one many positive reasons to use a hearing aid.  Others include a lessened risk of depression and better mood. No one likes to think they are at risk for dementia. However, you can fight back and take steps to reduce the odds by keeping fit and healthy. A balanced diet and staying physically active is an important aspect, because it reduces your risk of cardiovascular disease. The latter can cause hearing loss if the tiny blood vessels to the ear that supply the organ of hearing become furred up. This is a “chicken and egg” situation, because doctors now look for certain changes in the audiogram’s pattern of hearing loss as a warning sign of cardiovascular disease. Consider having your hearing tested regularly. Early detection of a problem enables you to be fitted with a hearing device, which in turn protects your hearing health and slows deterioration of your listening skills. The opposite, not addressing a hearing loss problem, is associated with an increased risk of dementia, trips or falls, and when treatment is required, longer stays in hospital. All things considered, it pays to take care of your hearing health. If you suspect your hearing is not what it should be, come to grips with the issue and protect your overall well-being by booking a hearing test.
