Adjust Your Attitude toward “Growing Older”

New studies suggest our attitude toward growing older may affect how well we do with our own aging process. Researchers report findings that show those who negatively view aging may have a higher likelihood of developing changes in the brain associated with Alzheimer’s disease. One such study was published in the American Psychological Association’s journal, Psychology and Aging. Its authors suggest if a person shifts their belief about aging to a more positive view; it may be beneficial in helping to mitigate the ravages of Alzheimer’s.

Associate professor of public health and psychology at the Yale School of Public Health and the study’s leader, Becca Levy said, “We believe it is the stress generated by the negative beliefs about aging that individuals sometimes internalize from society that can result in pathological brain changes.” She says while these findings are concerning, “it is encouraging to realize that these negative beliefs about aging can be mitigated, and positive beliefs about aging can be reinforced, so that the adverse impact is not inevitable.”

The research was part of the Baltimore Longitudinal Study of Aging; a long-term study based out of Baltimore. All participants had been part of the study for decades and were healthy adults free of Alzheimer’s or other forms of dementia. The survey questions focused on individuals' beliefs regarding aging. Negative views included the belief elderly people are sickly, absent-minded, have little to contribute, and are unable to concentrate well. Positive beliefs included thinking older people can lead vibrant lives and be actively engaged in society.

Participants were also given regular MRI brain scans to check for signs of Alzheimer’s. Those who answered questions about aging negatively were discovered to have a “greater decline in the volume of the hippocampus, a part of the brain critical for memory.” Researchers explain this is important as “the hippocampus is one of the first areas of the brain to shrink in the early stages of Alzheimer’s disease.” Brain autopsies were conducted on 74 patients who died during the study. Those who were more negative about aging had more plaques and tangles in their brain, which is associated with Alzheimer’s; than their more positive counterparts.

Becca Levy and other researchers hypothesize that Americans hold a more negative view on aging as compared to countries such as India; it could contribute to Alzheimer’s being five times more prevalent in our country. However, while positive thinking is no guarantee for good brain health, it certainly helps us feel better.
