Why do some people have more severe cognitive deficit as a result of Alzheimer's Disease than others? Dr. Yaakov Stern, Ph.D. is studying one possible explanation - "cognitive reserve" – in which additional brain circuits become active when other parts of the brain become too damaged by the plaques and tangles of the disease to function. He addresses the question using a combination of epidemiological and functional imaging approaches. Dr. Stern is a professor of clinical neuropsychology in the departments of Neurology, Psychiatry, and Psychology, as well as the in Sergievsky Center and the Taub Institute for the Research on Alzheimer's Disease and the Aging Brain, at Columbia University College of Physicians and Surgeons. Dr. Stern directs the Cognitive Neuroscience division at CUMC, which focuses on cognitive-experimental and neuroimaging approaches to cognition across the life span with an emphasis on normal and abnormal aging, and degenerative neurological disease. The division is currently studyingmemory: explicit recall, source memory, working memory, priming; basic timing mechanisms and their relation to other cognitive tasks; effects of literacy, education, ethnicity, and acculturation on neuropsychological task performance; and traditional neuropsychological battery-based studies of cognition in normal aging and our diseases of interest.
