Mental Stimulation Speeds Effects Of Dementia
(Undated) -- Having an active mind is a mixed bag when it comes to dementia. A study conducted by researchers at Chicago's Rush University Medical Center found a mentally stimulating lifestyle can slow the brain's decline at first, but tends to speed up the decline when full-on dementia hits. The 12-year study followed more than eleven-hundred people over age 65 who didn't have dementia to begin with. At first, their rate of cognitive decline slowed for every point they scored on a cognitive activity scale. However, after they were diagnosed with Alzheimer's Disease, each point on the cognitive activity scale sped up their average rate of decline per year. The researchers believe the delayed onset of dementia may be because people with mentally stimulating lifestyles are better able to compensate for the effects of the disease in the brain. When Alzheimer's hits, they suffer the effects of all the damage that previously went unnoticed. The study is published in the journal "Neurology." |
