Could Alzheimer's be a form of diabetes? Brain levels of insulin and its related cellular receptors fall during the early stages of Alzheimer's, and as insulin levels continue to drop, the disease becomes more severe. Now, doctors are looking at memory problems like Alzheimer’s disease as a form of brain starvation, and one doctor says glucose metabolism can be the key to helping prevent this deadly disease.
Alzheimer's disease is the most common form of dementia. Most often, it is diagnosed in people over 65, although the less-prevalent, early-onset Alzheimer's can occur much earlier. In 2006, there were over 26 million sufferers worldwide. Alzheimer's is predicted to affect 1 in 85 people globally by 2050. A recent study showed the inability of the brain to properly use glucose might be a key factor in the development of the disease.
"Type 1 and 2 diabetes are diabetes of the body, which means the body can’t handle sugar properly. Type 3 diabetes means the brain can’t handle sugar properly, "Larry McCleary, M.D., a neurosurgeon and author of Feed your Brain, Lose Your Belly, told Ivanhoe."If you can’t handle your primary fuel source, then you can’t generate energy, and you lose function, and that’s pretty much what happens in Alzheimer’s disease," Dr. McCleary explained. "Changes in brain glucose metabolism can occur in people who have no symptoms. Their brains are functioning normally in their 20’s and 30’s, but yet if you do scan, you can see subtle changes in glucose metabolism in the brain and not just anywhere in the brain. They are actually in the regions where Alzheimer’s disease develops when you’re 65 or 75 years old." Read more: redorbit.com

Nutrients and mental performance
In this guest article, Louise Dye, Professor of Nutrition and Behaviour in the Human Appetite Research Unit at the Institute of Psychological Sciences at the University of Leeds, outlines why the nutrient-mental performance link is a difficult one to quantify and translate into the market.
