A link between hearing loss and dementia?

Researchers in the United States have found a close relationship between losing your hearing and memory loss. The study was carried out at the Johns Hopkins School of Medicine in Baltimore. 693 men and women aged between 36-90 years were studied. All participants underwent initial hearing and cognitive testing at the outset of the study between 1990 and 1994; none of the participants had dementia at that point.
These participants were then followed for the development of Alzheimer’s disease and dementia through to 2008 - an average of 12 years.

The study revealed that the risk of dementia increased among participants with at least a mild 25-decibel reduced hearing ability. Participants with more severe hearing loss were most likely to be diagnosed with dementia – and even Alzheimer's. The relationship between Alzheimer's and hearing loss should come as no surprise - After all, how can you remember what someone said if you didn't hear them say it.

Several symptoms are common to both Alzheimer's and untreated hearing loss. These symptoms include depression, anxiety, feelings of isolation and problems with talking and understanding what is being said. In addition, people with either Alzheimer's or unidentified hearing loss may have inappropriate responses to social cues, lower scores on tests of mental function, attitudes of denial, defensiveness, or negativity, and increased distrust of others' motives, even those of family and friends.

Research has shown that hearing loss damages interpersonal and family relationships and may lead to emotional instability, low self-esteem and even depression. Untreated hearing loss not only reduces one's quality of life, but it can also result in the brain losing its capacity to recognise everyday sounds.

Therefore, it is imperative that a hearing loss is dealt with as quickly as possible and using the most appropriate and up to date technology available will significantly ease everyday communication.
