Waisman Center partners on new multi-site NIH initiative to find Alzheimer’s biomarkers in Down syndrome
Brad Christian, PhD, Waisman investigator and associate professor of medical physics and psychiatry, is part of a new National Institutes of Health initiative to identify biomarkers and track the progression of Alzheimer’s in people with Down syndrome.
Frayed nerve bundle may spur autism’s motor, social deficits
A new study by Waisman Center investigators Andy Alexander, PhD, professor of medical physics and psychiatry, Janet Lainhart, MD, professor of psychiatry and Brittany Travers, PhD, assistant professor of kinesiology, indicates a nerve bundle at the base of the brain is structurally compromised in people with autism. The study was recently featured by the Simons Foundation Autism Research Initiative.
