Study uncovers link between hearing loss and dementia

A direct causal relationship between hearing loss and the development of dementia has not been proven, despite widespread beliefs that deafness is a major risk factor. This was reported on March 12 by Medical Xpress magazine.

The researchers note that cognitive decline and hearing impairment often occur simultaneously, but the mechanisms of their interaction are not fully understood. Common risk assessments show the scale of the problem at the societal level, but do not mean that a particular person with hearing loss will necessarily experience dementia. The main contribution to the risk is made by age, genetics and the state of the cardiovascular system.

According to experts, it is extremely important to pay attention to clear communication, since such misconceptions can arise due to the way the risk of developing dementia is calculated and presented, as well as due to a specific description of the research results. According to the publication, exaggerating the link between hearing loss and dementia can create unrealistic expectations and discourage some from contacting a specialist.

Researchers have suggested several ways that hearing loss may affect cognitive decline, including the ability to alter the brain's information processing pathways, as well as social activity.,

Often, hearing loss does accompany dementia. If left untreated, it can also reduce the effectiveness of other forms of support, and hearing difficulties themselves can make it difficult to participate in group classes or therapy sessions. It is also emphasized that about 80% of people with hearing impairments live in low- and middle-income countries.

Although the relationship between hearing loss and dementia continues to be studied, it is known that deafness plays a role not only for cognitive functions. Supporting people to improve their hearing can help them stay connected, as well as be involved and independent.

On March 9, Medical Xpress reported on brain training methods and reducing the risk of dementia. According to researchers, the physical condition of the body is directly related to the work of the brain. It was clarified that, in addition to mental exercises, regular physical activity, blood pressure control, adequate sleep and vaccination in old age are recommended.
