- Simple interventions like hearing aids can improve quality of life.
- Awareness and early intervention are key to prevention.
New Delhi, July 16 (NationPress) A recent study reveals that hearing loss compounded by feelings of loneliness significantly accelerates cognitive decline, ultimately leading to dementia in older adults.
Researchers from the University of Geneva (UNIGE) in Switzerland have highlighted that challenges such as isolation, communication barriers, and diminished awareness due to hearing impairment pose real difficulties in daily living.
Published in the journal Communications Psychology, the findings indicate that cognitive decline progresses more rapidly in individuals experiencing hearing loss, particularly among those who feel lonely, irrespective of their social isolation status.
Matthias Kliegel, a professor at UNIGE's Cognitive Ageing Laboratory, stated, “We discovered that individuals who were socially engaged but felt lonely experienced accelerated cognitive decline when facing hearing impairment.”
The research team analyzed data from 33,000 older adults across 12 European nations to assess the combined effects of hearing loss and loneliness on memory.
Three distinct profiles emerged based on social isolation and perceived loneliness: those who are socially isolated and feel lonely, those who feel lonely but are not isolated, and those who are isolated yet do not feel lonely.
The findings underscore the necessity of addressing both hearing impairment and the emotional and social aspects of individuals to combat cognitive decline effectively.
This is particularly vital for those who may not be socially isolated but still grapple with loneliness; simple interventions like hearing aids could drastically enhance their social engagement, according to the researchers.
“These individuals are already part of a social network, so eliminating a sensory barrier could strengthen their participation and safeguard their cognitive health,” noted Charikleia Lampraki, a postdoctoral researcher at UNIGE.
The World Health Organization (WHO) projects that nearly 2.5 billion people will face hearing loss or impairment by 2050.
Currently, over 25 percent of individuals aged 60 and above experience a disabling hearing impairment. This reduction in hearing ability can increase the risk of cognitive decline by two to three times, emphasizing the urgent need for early and preventive hearing care.
Point of View
It is imperative to highlight the critical intersection of health and emotional well-being in our aging population. This study underscores the urgent need for awareness and intervention regarding hearing loss and loneliness, as they play pivotal roles in cognitive health. Addressing these issues is not just a medical concern but a societal one that demands immediate attention.
