How Brain Imaging Could Help Predict Alzheimer's

How Brain Imaging Could Help Predict Alzheimer's
Developing drugs that effectively slow the course of Alzheimer’s disease has been notoriously difficult. Scientists and drug developers believe that a large part of the problem is that they are testing these drugs too late in the progression of the disease, when significant damage to the brain makes intervention much more difficult. “Drugs like Lilly’s gamma secretase inhibitor failed because they were tested in the wrong group of patients,” says Sangram Sisodia, director of the Center for Molecular Neurobiology at the University of Chicago. People in the mid or late stages of the disease “are too far gone, there is nothing you can do.” New brain imaging research may help solve that problem. Two studies presented at the Society for Neuroscience conference in San Diego this week identified changes in the brains of people who would go on to develop the disease.

Religion May Cause Brain Atrophy -- Science of the Spirit Faith can open your mind but it can also cause your brain to shrink at a different rate, research suggests. Researchers at Duke University Medical Centre in the US claim to have discovered a correlation between religious practices and changes in the brains of older adults. The study, published in the open-access science journal, Public Library of Science ONE, asked 268 people aged 58 to 84 about their religious group, spiritual practices and life-changing religious experiences. Changes in the volume of their hippocampus, the region of the brain associated with learning and memory, were tracked using MRI scans, over two to eight years. Protestants who did not identify themselves as born-again were found to have less atrophy in the hippocampus region than did born-again Protestants, Catholics or those with no religious affiliation. Although the brain tends to shrink with age, atrophy in the hippocampus has been linked with depression and Alzheimer's disease.
