Hearing and Vision Loss May Speed Development of Cognitive Problems

Journal of the American Geriatrics Society Research Summary

Cognitive decline ranges in severity from mild cognitive impairment (MCI) to Alzheimer’s disease and related dementias (ADRD). It is marked by memory loss and difficulty thinking and making decisions. Cognitive decline is a significant, common challenge to older adults’ well-being and their ability to live independently.

Today, cognitive impairment and ADRD are major global public health and social concerns as the population of older adults rises around the world. By 2050, more than 152 million people will be affected by these conditions. That’s why many countries, including the United States, see the prevention of ADRD as a key public health priority and are studying programs to help stem these diseases.

One way to prevent cognitive impairment and ADRD is to treat the problems that raise the risk for developing them. Two of these risk factors are hearing and vision loss. Currently, about 60 percent of people aged 70 years or older are affected by hearing loss, 40 percent are affected by vision loss, and 23 percent of older adults have both vision and hearing loss. Some studies have suggested that having both hearing and vision loss may be linked to poorer cognitive function or to a faster rate of cognitive decline.

However, more specific studies are needed to obtain more accurate information about these two sensory problems and their relationship to cognitive decline, suggests a  research team that examined the associations between having loss of one sensory function — hearing or vision — and cognitive decline, as well as the associations between having both types of sensory loss and cognitive decline. They published their findings in the Journal of the American Geriatrics Society. Continue reading

Having Poor Vision Can Raise Risk for Falls Among Older Adults

Journal of the American Geriatrics Society Research Summary

Vision impairment and blindness affect one in 11 Americans age 65 and older. Because our population is aging, the number of older adults with vision problems is predicted to rise. Older adults who have impaired vision may be at risk for decreased independence, poorer well-being, and an increased risk of falls. For example, in any given year, approximately 30 percent of adults over age 65 will fall. Having impaired vision more than doubles this risk.

For older adults, falls are a major cause of illness and death. Even having a fear of falling is a challenge that can limit activity and worsen quality of life and independence as you age.

However, we don’t have much information on how often visually impaired older adults experience a fall, and we have even less information about what happens to them after a fall. A team of researchers suggested that we need this information in order to understand the scope of the problem and create ways to prevent falls in visually impaired older adults.

To learn more, the research team examined information from the National Health and Aging Trends Study (NHATS). They published their study in the Journal of the American Geriatrics Society. Continue reading
