Finally tonight, a sobering report with a silver lining. New numbers out today predict an explosion in Alzheimer’s disease in this country. An estimated ten million baby boomers - one in every eight - will develop the disease. New treatments are years away, but there is evidence people cantake steps to prevent the memory-robbing disease. Here’s John McKenzie.
For millions of Americans, the new Alzheimer’s numbers confirm their worst fears. Fran Hershkowitz’s mother began losing her memory a decade ago. “It’s frightening to think that one day, this is going to be me.” To prevent Alzheimer’s, the most compelling evidence today points to physical exercise.
Several large studies have shown that people who stay physically active are less likely to develop Alzheimer’s. Now scientists are saying it is no coincidence. Researchers bred mice to develop the specific kind of plaque in the brain seen in Alzheimer’s disease. Some mice were allowed to exercise, some were not.
The brains of the sedentary mice were riddled with those harmful plaques. But look, the physically active mice had 50 to 80 percent less plaque. But how? Further tests revealed the exercise had produced more of a chemical in the brain that prevents plaque build-up, and more of these tinyblood vessels to allow plaque to escape. “So it’s carried to those organs, like the liver, where it could be ultimately destroyed.”
Any exercise that raises your heart rate for 30 to 45 minutes, several times a week, can lower your risk of Alzheimer’s. “Regular physical exercise is probably the best means we have of preventing Alzheimer’s disease today, better than medications, better than intellectual activity, and better than other supplements and diet.”
To avoid another generation of this disease, there is something that can be done, now. John McKenzie, ABC News, New York.
