Frequent Brain Stimulation Reduces Risk

For the study, more than 700 people in Chicago, IL, with an average age of 80 underwent yearly cognitive testing for up to five years. Participants were part of the Rush Memory and Aging Project, a longitudinal study of more than 1,200 older people. Of the participants, 90 developed Alzheimer’s disease. Researchers also performed a brain autopsy on the 102 participants who died.

The study found a cognitively active person in old age was 2.6 times less likely to develop dementia and Alzheimer’s disease than a cognitively inactive person in old age. This association remained after controlling for past cognitive activity, lifetime socioeconomic status, and current social and physical activity. Researchers say the findings may be used to help prevent Alzheimer’s disease.

“Alzheimer’s disease is among the most feared consequences of old age,” said study author Robert S. Wilson, PhD, with the Rush Alzheimer’s Disease Center at Rush University Medical Center in Chicago. “The enormous public health problems posed by the disease are expected to increase during the coming decades as the proportion of old people in the United States increases. This underscores the urgent need for strategies to prevent the disease or delay its onset.”

Wilson says the study also found frequent cognitive activity during old age, such as visiting a library or attending a play, was associated with reduced risk of mild cognitive impairment, a transitional stage between normal aging and dementia, and less rapid decline in cognitive function.; Source: American Academy of Neurology
