Carotenoids are thought to protect against Alzheimer's disease because of their antioxidant properties and their accumulation in the brain. However, a new study from Tufts University is putting the theory into question. More than a century has passed since the German physician Dr. Alois Alzheimer first presented evidence on the case of Auguste Deter, who at only 51 suffered from severe memory loss and other psychological changes. At autopsy, Dr. Alzheimer found his patient had severe shrinkage and abnormal deposits of the nerve cells. "That was in 1906," said nutritionist Annie Roe, a USDA researcher at Tufts University, who presented her laboratory's findings on April 21 at Experimental Biology 2012 in San Diego. "There's still disparity among scientists as to the etiology of this rapidly growing disease as we now know as Alzheimer's disease." Currently, in the United States there are 5.3 million people with Alzheimer's disease. Unless new metho...

Now, for the second keynote at American College of Nutrition conference in New York City we're listening to Mark Mattson, Ph.D. He starts out talking about his work in the laboratory of neurosciences at National Institutes of Aging. He talks about what happens during aging in the brain. More and more as people get older, neurons age and die, predisposing us to Alzheimer's and other brain diseases. The mechanisms on how this happens are being shown and he discusses the different pathways. Dietary energy restriction, exercise, cognitive enrichment promote neuroprotection (hormesis?) by reducing oxidative stress and inflammation. Current trends in Alzheimer's showing it's a huge issue that's not being dealt with. We need a war on it like we have on cancer. Many people die from Alzheimer's and it's a tax on society. He discusses amyloid plaques and neurofibrillary tangles (with tau) that is involved in AD pathogenesis. There's a number of animal models for ...
