A recent study has identified that a combination of hearing loss and feelings of loneliness can significantly accelerate cognitive decline in older adults. Researchers from the University of Geneva reached this conclusion after analyzing data from over 33,000 Europeans aged 50 and above. The findings have been published in the journal Communications Psychology.
The scientists utilized data from the extensive SHARE project, which biennially assesses the health, social connections, and cognitive abilities of participants across 12 European countries. Their analysis revealed that the most rapid memory deterioration occurred in individuals with hearing impairments who, despite not being socially isolated, reported feeling lonely.
According to the authors, it is this subjective feeling of loneliness that acts as an `accelerator` for cognitive decline, even if a person actively engages with others. Hearing loss further exacerbates the issue by limiting opportunities for full participation in conversations and social activities.
The researchers emphasize that preventive care for hearing impairments—such as the timely use of hearing aids—could help mitigate the risk of memory fade and protect the cognitive health of older individuals.
Earlier studies have also shown that music can improve mood and memory, which is why it is often used in therapies for Alzheimer`s disease and dementia.
