Brain training may forestall dementia onset for years, new study says

If you're intent on keeping dementia at bay, new research suggests you'll need more than crossword puzzles, aerobic exercise and an active social life. In a study released Sunday, researchers found that older adults who did exercises to shore up the speed at which they processed visual information could cut by nearly half their likelihood of cognitive decline or dementia over a 10-year period. The new clinical trial results, presented Sunday at the Alzheimer's Assn.'s International Conference in Toronto, establish specialized brain training as a potentially powerful strategy to prevent Alzheimer's Disease and other afflictions, including normal aging, that sap memory and reduce function. With 76 million baby boomers reaching the age of maximum vulnerability to Alzheimer's and with no effective treatments available to alter the disease's progression, researchers are keen to find ways to prevent or delay the onset of the memory-robbing disease. The new research suggests that even years after it is administered, an inexpensive intervention without unwanted side effects might forestall dementia symptoms.
