Harry Kerasidis, M.D., founder of XLNTbrain Sport™, is one of only a few elite neurologists in the world specializing in the impairment of cognitive and emotional performance resulting from concussions. He co-founded XLNTbrain LLC after 25 years studying the changes of the electrophysiology of the brain as it relates to behavior, cognitive function and emotional function resulting from various brain trauma, including concussions.Dr. Kerasidis has treated thousands of concussion injuries in his practice, Chesapeake Neurology Associates, based in Prince Frederick, Maryland. A highly sought-after cognitive neurologist, he has helped patients with a variety of cognitive and behavioral disorders including memory loss, sleep deprivation, ADD, dementia, Alzheimer's, and traumatic brain injury.Through his experience, Dr. Kerasidis noticed existing concussion baseline testing lacked critical cognitive measures. So he created and began using his own baseline assessment, acute management and recovery care plan, which has been incorporated into XLNTbrain Sport™ (XLNTbrain.com), a mobile- and online-based concussion management program for all sports and levels.Dr. Kerasidis has a distinguished career helping the general public, scholars and medical professionals understand the link between the physiology of the brain and behavior. At Calvert Memorial Hospital, he serves as the Medical Director for the Center for Neuroscience, Medical Director for the hospital’s Sleep Disorders Center and Medical Director for the hospital’s Stroke Center.
