Scientists are closing in on a long-sought goal: A blood test to screen people for Alzheimer's disease. http://medicalxpress.com/news/2011-07-blood-alzheimer.html Diseases, Conditions, Syndromes Wed, 20 Jul 2011 04:01:27 EST news230353254 Imaging studies have repeatedly found that people with depression have smaller hippocampal volumes than healthy individuals. The hippocampus is a brain region involved in learning and memory, spatial navigation, and the evaluation of complex life situations or "contexts". However, because in prior studies hippocampal volume was only measured in people once they became depressed, it has been unclear whether a small hippocampus renders a person vulnerable to developing depression, or whether it is a consequence of depression. http://medicalxpress.com/news/2011-07-small-hippocampus-depression-elderly-factor.html Psychology & Psychiatry Tue, 19 Jul 2011 11:05:34 EST news230292317 Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression, new research in mice suggests. http://medicalxpress.com/news/2011-07-air-pollution-linked-memory-problems.html Psychology & Psychiatry Tue, 05 Jul 2011 10:09:29 EST news229079323 A new biomarker may help identify which people with mild memory deficits will go on to develop Alzheimer's disease, according to a new study published in the June 22, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.
