Brain boosting tips

The Alzheimer's Association estimates that 5.2 million Americans have memory and language problems caused by Alzheimer's disease.

"We're seeing baby boomers and even people in their 30s worrying about brain fitness," said Asenath LaRue, a neuropsychologist at Wisconsin Alzheimer's Institute and a senior scientist at University of Wisconsin School of Medicine and Public Health. "It's not a stretch to think we may begin hiring brain coaches in addition to physical fitness."

Researchers are beginning to believe in a threepronged strategy for retaining memory:

•Be physically active. Regular activity, not necessarily planned exercise, seems to relate to brain fitness. Activities like gardening, dancing and cleaning could increase chances of maintaining brain health.

•Challenge your brain. Calculate, do word search games and crossword puzzles, and go to lectures, concerts and museums. Early observational studies have indicated the benefits of mind challenges.

•Stay socially active. People who are active in broad social networks may hold up better cognitively than those who are less socially active.

"While we don't know at what point in an individual's life the three factors have maximum impact, the theory is that the better developed your coping resources, the more likely you are to withstand brain changes affecting memory and thinking," LaRue said.

Researchers don't believe brain workouts will stop or reverse dementia and Alzheimer's disease, but they may forestall memory loss and confusion.

"Once you have it, you can't reverse it, but with a combination of lifestyle adjustments and medications, many of the most challenging symptoms can be managed effectively," LaRue said.
