Hearing loss is linked to an increased risk of depression

(Reuters Health) – Older adults with hearing loss may have the possibility of developing depression properties, pending a research review.

Currently, more than 1.3 billion people are currently living with some form of hearing loss, and their degrees are expected to rise with the aging population, the study team notes in the Gerontologist. Approximately 13 per cent of adults aged 40 to 49 years of age have hearing loss, as 45% of people aged 60 to 69 years old and 90 percent of adults aged 80 and over , the authors write.

To assess the link between hearing loss and depression, researchers analyzed data from 35 previous studies and a total of 147,148 participants aged at least 60 years.

Compared to people without hearing loss, older adults with some hearing loss were 47 per cent more likely to have depressive symptoms, who had received the study.

“We often know that older adults with hearing loss withdraw from social events, such as family events, because they find it difficult to understand others in bleak situations, which can lead to emotional and social isolation. said, ”said Blake Lawrence, author of the leading study, Science Science Institute, Subiaco, and the University of Western Australia in Crawley.

“We also know that older adults with hearing loss are more likely to experience mild cognitive decline and will have difficulty completing daily activities, which could have a further negative impact on their quality of life and t increase the risk of depression, ”Lawrence said by email.

“Changes in old age often described as a“ normal age ”may, therefore, contribute to the development of depression symptoms among older adults with hearing loss,” he said. Lawrence.

The relationship between hearing loss and depression did not appear to have affected whether or not people used hearing aids.

One limitation of the analysis was that it included studies with a wide range of methods to assess hearing loss and depression properties.

However, the results of the analysis add to the evidence suggesting that there is a link between hearing loss and depression. Nicholas Reed from the Cochlear Center for Public Health Listening and Health at Johns Hopkins University Medical School in Baltimore.

Firstly, the loss of hearing affects communication and affects balance, which could lead to social isolation and reduced physical activity, leading to depression, said Reed.

Hearing loss can be caused by tinnitus, or a ring to remember or ear in the ear, which may be debilitating especially in some cases and contributes to depression, Reed, who were not involved in the study, said by email.

In addition, hearing loss may trigger changes in the brain that contribute to depression.

“When we hear loss, it also means that we are sending a weaker hearing signal to our brain for processing,” Reed said. “This weak sign could mean that our brain must go over each other to understand the sound (ie speech) that might come from other process costs (eg working memory). ). Also, the weak sign may cause certain neural areas to be reorganized, which could change the way our brain functions, including features that regulate depression, t . "

While the study does not examine whether hearing loss can prevent depression or other health problems, people should still get help for hearing difficulties, said David Loughrey, a researcher at Global Health Brain Institute in Trinity College, Dublin. Dublin did not participate in the study.

“Hearing loss is associated with difficulties in everyday life, including difficulty with socialization and fatigue due to the increased mental effort required to understand the speech, particularly in toxic environments,” said Loughcrew by email. “If a person has difficulties with hearing loss or has any concerns about their mental well-being, they should consult a medical professional who can help them.” T
