Leisure Activities and the Risk of Dementia in the Elderly — NEJM


"A recent study at the Einstein College of Medicine, Yeshiva University in Bronx showed that dancing reduced the risk of dementia, a brain disorder that includes Alzheimer's disease affecting 6 to 7 million Americans over the age of 60. The result of the research led by Dr. Joseph Verghese, assistant professor of neurology, was reported in the New England Journal of Medicine in June 2003 (Vol. 348,pp 2508-16)."


"The research involved 469 men and women aged 75 and older, and the time span of 21 years that began in 1980. All participants were screened at the start to ensure that they were free of dementia. The researchers studied lifestyle of each participant to see if he or she engaged in some of the 6 cognitive activities (reading, writing, doing crossword puzzles, playing musical instruments, taking part in group discussion, and playing board games) and 11 physical activities (dancing, numerous sports, housework, and baby-sitting).
They followed the activities of each for an average of 5.1 years. Among the participants were 130 who danced frequently (3 or 4 times a week), 83 who swam frequently, 26 who bicycled frequently, and 19 who played games frequently.
The results revealed that frequent cognitive activities reduced the risk of dementia. There was no big surprise there, for other earlier studies indicated that much. The most surprising result was that, of all the physical activities, dancing was the only activity that reduced the risk of dementia.
The frequency of activities was also an important factor. For example, those who danced 4 times a week showed 76 percent less incidence of dementia than those who did only once a week or not at all. Naturally, the more you dance the greater the benefit you reap--as far as dementia is concerned."

So...have fun with your dancing and  
keep your brain healthy!!
