People who participate in arts and craft activities and who socialize in middle and old age may delay the development in very old age of the thinking and memory problems that often lead to dementia, according to a new study.
Findings were published April 8 on the website of Neurology, the medical journal of the American Academy of Neurology.
People ages 85 and older make up the fastest growing age group in the United States, according to the U.S. Census Bureau. The World Health Organization projects the number of people ages 80 and older worldwide will quadruple from 2000 to 2050.
“As millions of older U.S. adults are reaching the age where they may experience these memory and thinking problems called mild cognitive impairment, it is important we look to find lifestyle changes that may stave off the condition,” study author Rosebud Roberts, MB, ChB, MS, of Mayo Clinic in Rochester, Minn., said in a news release. “Our study supports the idea that engaging the mind may protect neurons, or the building blocks of the brain, from dying, stimulate growth of new neurons, or may help recruit new neurons to maintain cognitive activities in old age.”
The study involved 256 people with an average age of 87 who were free of memory and thinking problems at the start of the study. The participants reported their participation in arts, such as painting, drawing and sculpting; crafts, such as woodworking, pottery ceramics, quilting, quilling and sewing; social activities, such as going to the theater, movies, concerts, socializing with friends, book clubs, Bible study and travel; and computer activities such as using the Internet, computer games, conducting web searches and online purchases.
After an average of four years, 121 people developed mild cognitive impairment. Participants who engaged in arts in both middle and old age were 73% less likely to develop MCI than those who did not report engaging in artistic activities. Those who crafted in middle and old age were 45% less likely to develop MCI, researchers found, and people who socialized in middle and old age were 55% less likely to develop MCI compared with those who did not engage in like activities. Computer use in later life was associated with a 53% reduced risk of MCI, the findings showed.
On the other hand, the study found risk factors such as having the APOE gene that is linked to increased risk of late-onset Alzheimer’s, having high blood pressure in middle age, depression and risk factors related to blood vessels increased the risk of developing MCI.
The study was supported by the National Institute on Aging, the Mayo Foundation for Medical Education and Research and the Rochester Epidemiology 53 Project.
