Steven T. DeKosky, MD

Stephen Dekosky

Dr. Steven DeKosky is the Aerts-Cosper Professor of Alzheimer’s Research at the University of Florida College of Medicine, and is Deputy Director of the McKnight Brain Institute. His basic research centers on structural and neurochemical changes in human brain in aging and dementia and effects of traumatic brain injury (TBI). Beginning trauma studies as a Principal Investigator in the University of Pittsburgh Brain Trauma Research Center in 1992, he studied similarities in the injury cascades of TBI and AD. Dr. DeKosky has served on and led numerous NIH review and advisory committees, and taught and mentored in clinical research training programs sponsored by the National Institute on Aging (NIA) and the National Institute of Neurological Disorders and Stroke (NINDS).

Dr. DeKosky was a member of the national Board of Directors of the Alzheimer’s Association from 1994 to 2002 (Board Vice Chair in 2001-2002), and again from 2003 to 2010. He served as Chair of the Section on Geriatrics of the American Academy of Neurology (AAN), and chaired the AAN Practice Parameters Committee for Early Detection, Diagnosis and Management of Dementia. He is the founding Chair of the Advisory Council of ISTAART, the International Society to Advance Alzheimer’s Disease Research and Treatment. He has testified multiple times before U.S. Senate Committees for greater research funding for Alzheimer’s disease, and has met with government officials in other countries as a consultant and advocate for programs and support for people with dementia.
