Exercise Delays Dementia Video News Release

Regular exercise is associated with delayed onset of dementia and Alzheimer's disease, according to a study in the latest issue of the Annals of Internal Medicine. The study followed 1,740 participants aged 65 and older over a six-year period. The researchers contacted the participants every two years to assess exercise frequency, cognitive function, lifestyle characteristics and other potential risk factors for dementia. People who exercised three or more times a week had a 30 to 40 percent lower risk for developing dementia compared with those who exercised fewer than three times per week.
