Nicotine May Play Key Role in Promising Alzheimer’s Therapy

COLLEGE PARK, Md. — A team of neuroscientists has discovered important new information in the search for an effective treatment for Alzheimer’s disease, the debilitating neurological disorder that afflicts more than 5.3 million Americans and is the sixth-leading cause of death in the United States. Hey-Kyoung Lee , associate professor in the University of Maryland Department of Biology, and her research team have shown that they may be able to eliminate debilitating side effects caused by a promising Alzheimer’s drug by stimulating the brain’s nicotine receptors.
