AAN Says Brain Exercises May Slow Cognitive Decline Earlier, Only to Speed Up Dementia Later

Well isn’t THIS cheery news! The has just released a paper stating that the old “brain advice” of “use it or lose it” may not hold much water.
New shows that mentally stimulating activities such as crossword puzzles, reading and listening to the radio may, at first, slow the decline of thinking skills but speed up later in old age. The research is published in the September 1, 2010, online issue of Neurology®, the of the American Academy of Neurology .
“Our results suggest that the benefit of delaying the initial signs of cognitive decline may come at the cost of more rapid dementia progression later on, but the question is why does this happen?” said study author Robert S. Wilson, , with in Chicago.
According to Wilson, mentally stimulating activities may somehow enhance the brain’s ability to function relatively normally despite the buildup of lesions in the brain associated with dementia. However, once they are diagnosed with dementia, people who have a more mentally active lifestyle are likely to have more brain changes related to dementia compared to those without a lot of mental activity. As a result, those with more mentally active lifestyles may experience a faster rate of decline once dementia begins.
Wilson noted that mental activities compress the time period that a person spends with dementia, delaying its start and then speeding up its progress. “This reduces the overall amount of time that a person may suffer from dementia,” he said.
So you don’t have dementia as long, you just get it HARDER?
For the study, researchers evaluated the mental activities of 1,157 people age 65 or older who did not have dementia at the start of the nearly 12-year study. People answered questions about how often they participated in mental activities such as listening to the radio, watching television, reading, playing games and going to a museum; for this five-point cognitive activity scale, the more points scored, the more often people participated in mentally stimulating exercises.
During the next six years, the study found that the rate of cognitive decline in people without cognitive impairment was reduced by 52 percent for each point on the cognitive activity scale. For people with , the average rate of decline per year increased by 42 percent for each point on the cognitive activity scale.

I’m gonna go stare at the wall for awhile.
Unless I have something important to say in the interim…
