Journal of Alzheimer’s Report (Journal of Alzheimer’s Disease Reports) found that hearing impairment and visual impairment were independently associated with cognitive impairment.
After accounting for gender, age, and other sociodemographic characteristics,older adults with hearing impairment were more than twice as likely to have cognitive impairment, while those with visual impairment were more than twice as likely to have cognitive impairment. Older adults are more than three times more likely to suffer from cognitive impairment. When an older person experiences both hearing and vision impairments, the odds of cognitive impairment are eight times higher. About half of adults 65 and older have both hearing and visual impairments, as well as cognitive impairments.
In the past decade, several studies have linked hearing loss to dementia and cognitive decline, but less attention has been paid to vision loss and dual Sensory disturbances.
“Given that half of adults with vision and hearing loss experience severe cognitive problems, sensory loss can be used to help identify those with cognitive decline and dementia risk.” Director of the Institute for Life Course and Aging at the University of Toronto, Professor of the Factor-Inwentash School of Social Work (FIFSW) and Department of Family and Community Medicine, and lead author of the study Esme Fuller-Thomson said.

This study is based on a continuous US community 10 surveys (2008-2017), a nationally representative annual survey of approximately 500,000 US respondents age 65 and older. A total of 5.4 million older Americans participated in the study, including hospitalized and community-dwelling older adults.
“Dual sensory disorder prevents a person from making up for one sense lost by using the other sense.” Co-author, recently from Toronto University MSW graduate Aliya Nowczynski said: “Our findings underscore the need to reach older adults with dual sensory impairment to assess opportunities for early intervention.”
The authors highlight the importance of considering treatment options for sensory impairment to support cognitive health in older adults.
“It is important that we take into account the availability of common treatments for sensory impairments, such as hearing aids and cataract surgery.” Study co-author, MSW, University of Toronto Graduate Andie MacNeil said, “Those who have difficulty accessing these treatment options may be more prone to cognitive impairment. More research is needed to determine whether interventions for sensory impairments reduce the risk of subsequent cognitive decline.”
Several possible theories could explain the link between sensory impairment and cognitive impairment, including > Cognitive decline due to reduced auditory and visual input, social disengagement and loneliness due to communication problems, and age-related degeneration of the central nervous system.
“Future research is still needed to determine whether the link between sensory impairment and cognitive decline is causal,” Fuller-Thomson said. “Determining the mechanisms behind this relationship could help guide One step how to support older people.”
