FRIDAY, June 27 (HealthDay News) -- The key to a healthy mind in old age may lie in an active social life, a new study suggests.
"If you are socially engaged, you are at lower risk of dementia," said Dr. Valerie C. Crooks, a researcher at the Department of Research and Evaluation, Kaiser Permanente Southern California.
During her study, which followed more than 2,200 women ages 78 and older for four years, those with large social networks reduced their risk of getting dementia by 26 percent, she said.
