Daniel A. Cohen, M.D., M.M.Sc.

Sentara Neurology Specialists

Dr. Cohen is the Clinical Chief of Neurology for Sentara Medical Group and Associate Professor and Chair of Neurology for Eastern Virginia Medical School. He has subspecialty board certifications in both Behavioral (Cognitive) Neurology and Sleep Medicine. Dr. Cohen earned his medical degree from the University of Florida. He completed his Internal Medicine internship, Neurology residency, and fellowships in Cognitive Neurology and Sleep Medicine through Harvard Medical School at Boston's Beth Israel Deaconess Medical Center. He also completed a research fellowship in Sleep and Circadian Neurobiology at Brigham & Women's Hospital.

Dr. Cohen's outpatientclinical practice has largely focused on the treatment of cognitive and sleep disorders; his inpatient emphasis has shifted to hyperacute treatment of ischemic stroke. Dr. Cohen's research interests have included translational work related to the interface between sleep and cognition as well clinical trials for potentially disease-modifying therapies in Alzheimer's disease. He is passionate about training the next generation of clinicians in caring for those with neurological disorders.
