Washington: Having a greater objective in life may help cut down a person`s risk of developing Alzheimer`s disease later in life, say scientists. A team at Rush University Medical Center says greater purpose in life actually helps stave off the harmful changes in the brain associated with Alzheimer`s, the most common form of dementia, the `Archives of General Psychiatry` reported. Team leader Patricia A Boyle said: "Our study showed that people who reported greater purpose in life exhibited better cognition than those with less purpose in life even as plaques and tangles accumulated in their brains. "These findings suggest that purpose in life protects against the harmful effects of plaques and tangles on memory and other thinking abilities. This is encouraging and suggests that engaging in meaningful and purposeful activities promotes cognitive health in old age."
