Feeling lonely can do more than dampen your mood\u2014it may speed up how quickly your memory fades, especially if you\u2019re also struggling with hearing loss.<\/p>\n
A study analyzing data from 33,000 older Europeans found that emotional loneliness\u2014not just social isolation\u2014dramatically increased the risk of cognitive decline in people with hearing impairments.<\/p>\n
Hearing Loss and Loneliness: A Cognitive Threat
\nHearing loss can lead to more than just communication struggles and reduced awareness. It often contributes to a sense of isolation, and over time, it may also raise the risk of cognitive decline.<\/p>\n
Researchers at the University of Geneva (UNIGE) analyzed data from 33,000 older adults across Europe to explore how hearing impairment and feelings of loneliness might work together to affect memory. Their analysis revealed three key patterns based on levels of social isolation and perceived loneliness. The results showed that memory decline progressed more quickly in individuals who felt lonely, regardless of whether they were socially isolated, especially if they also experienced hearing loss.<\/p>\n
These findings, published in Communications Psychology, highlight the importance of early hearing care as a preventive measure.<\/p>\n
Global Impact of Hearing Impairment
\nThe World Health Organization (WHO) projects that by 2050, nearly 2.5 billion people will have some form of hearing impairment. Currently, over one-quarter of individuals aged 60 and older are affected by disabling hearing loss. Beyond the difficulties this causes in daily interactions, hearing loss has also been linked to a much higher chance of cognitive decline\u2014possibly two to three times greater than in those without hearing issues.<\/p>\n
A New Approach to Understanding Memory Loss
\nA joint team from the Lifespan Developmental Psychology Lab and the Cognitive Ageing Lab at the University of Geneva (UNIGE) set out to investigate whether the combination of hearing difficulties and feelings of loneliness \u2014 whether objectively measured or subjectively perceived \u2014 could be associated with accelerated memory decline in older age. \u201cThis is a relatively new approach,\u201d explains Charikleia Lampraki, postdoctoral researcher in the Lifespan Lab at UNIGE\u2019s Faculty of Psychology and Educational Sciences and first author of the study. \u201cWhile some studies have suggested that this might be a promising avenue, very few research teams have actually explored it.\u201d<\/p>\n
Massive European Dataset Powers Analysis
\nTo conduct their analyses, the researchers drew on data from the large-scale SHARE study (Survey of Health, Ageing and Retirement in Europe) \u2014 a longitudinal survey launched in 2002 that examines the health and ageing of Europeans aged 50 and over.<\/p>\n
\u201cWe used data from twelve countries, including Switzerland, representing a sample of 33,000 people,\u201d explains Andreas Ihle, assistant professor at the Lifespan Lab and director of the study. Participants are surveyed every two years on various aspects of their daily lives \u2014 such as activities, social connections, and perceptions \u2014 and undergo tests on cognitive functions like episodic memory, using standardised exercises.<\/p>\n
When Loneliness and Deafness Combine
\nThe scientists then examined whether these different profiles had different trajectories of cognitive decline, depending on the type of perceived isolation and the degree of hearing loss. \u201cWe found that people who were not socially isolated but who felt lonely saw their cognitive decline accelerate when they were deaf,\u201d says Matthias Kliegel, a full professor in the Cognitive Ageing Laboratory in the UNIGE\u2019s Faculty of Psychology and Educational Sciences, and co-author of the study.<\/p>\n
Boosting Cognitive Health with Simple Interventions
\nThese findings support the importance of addressing both hearing loss and the social and emotional dimensions of individuals in efforts to prevent cognitive decline. This is particularly crucial for people who are not socially isolated but still feel lonely \u2014 in such cases, simple hearing interventions, like using a hearing aid, may be enough to help them engage more fully in social life. \u201cThese individuals are already socially integrated, so it\u2019s a matter of removing a sensory barrier in order to reinforce their engagement and protect their cognitive health,\u201d concludes Charikleia Lampraki.<\/p>\n","protected":false},"excerpt":{"rendered":"
