...things are as terrifying as losing one's mind. Alzheimer's disease is the most common form of dementia among the elderly and affects as many as 4.5 million Americans, according to the U.S. National Institutes of Health. It currently has no cure. But recent research offers groundbreaking insight into what causes the disease, and how researchers could reduce people's risk. Walter Kukull, director of the U.S. National Alzheimer's Coordinating Center, explains...
...leader of men, Jack Gibson relied on two key attributes: simplicity and innovation. The first came naturally. The second arose from a life-changing trip to the U.S. almost 40 years ago. In his physical prime, Gibson, who died May 9 in Sydney after a long struggle with dementia, was a good player, rugged and brave. But that's not how he'll be remembered. He is recognized as the finest coach in the history of rugby league in Australia. Winner of five premierships between 1974 and 1983, he was last month named Coach of the Century by a panel...
...known as brain-derived neurotrophic factor (BDNF), a protein that stimulates the birth of new brain cells and then helps them differentiate and connect. BDNF also enhances neural plasticity, the process by which the brain changes in response to learning. In diseases like Alzheimer's, depression, Parkinson's and dementia, BDNF levels are low. In people who exercise, BDNF levels rise...
...sharp, you should strive for a diet that keeps your belly fat down. A study of more than 6,500 people published in the March 26 edition of the journal Neurology showed that people who were overweight and had a large belly were 2.3 times as likely to develop dementia as those with normal weight and belly size, while those who were obese and had a large belly were 3.6 times as likely. As scientists have long known, as belly fat--which disrupts body chemistry more than less reactive fat elsewhere on the body--increases, blood glucose rises along with...
...course, make your sputtering memory less frustrating. When you've misplaced your keys for the third time this month, it does you little good to be reminded that it all may be just too much glucose and too few blueberries. And nothing entirely removes the specter of true dementia and the horrors it implies. Still, figuring out how memory works is the most important step in figuring out how it can be fixed. When you can make some of the fixes yourself, the news is even better. If you needed one more reason to get your exercise and watch your...
