Yahoo news has reported that using your brain can help prevent Alzheimer's disease. Study after study has shown that people who remain mentally active (doing crossword puzzles, reading, learning a new dance, etc.) have a lower risk of Alzheimer's. Now, Yaakov Stern from the Columbia University neuroscience department, has shown why. Stern and his group scanned nineteen people using fMRI (functional magnetic resonance imaging) while they were engaged in a memory test. They saw that those who had higher IQs used their brains differently (for example, there was more frontal lobe activity). The Stern group has also shown that education can help prevent the disease. But they have said education needs to start early, before the brain is damaged.
(I've actually heard of this guy and have seen his papers before. He's done some interesting work. Would it be terrible of me to make a swipe at Ronald Reagan's brain use?)
