Harry Kerasidis, M.D., known as the XLNTbrain Sport’s “Brain Doctor,” is one of 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 of clinically treating mild traumatic brain injury and studying the changes of the electrophysiology of the brain as it relates to behavior, cognitive, and emotional function resulting from various brain trauma, including concussions.
Dr. Kerasidis has treated thousands of concussion injuries throughout his career. His private practice, Chesapeake Neurology Associates, is based in Prince Frederick, Maryland. A highly sought-after cognitive neurologist, he has helped patients with a variety of cognitive and behavioral disorders including cognitive impairment due to stroke, sleep deprivation, attention deficit disorder, dementia, and traumatic brain injury.
Through his experience, Dr. Kerasidis sought to fill the void of a much needed comprehensive sport concussion management program. He found existing concussion baseline testing lacked critical cognitive and emotional measures. He also saw the gross lack of integration of key elements of a comprehensive sport concussion management program. So he created and began using a baseline assessment, acute management and recovery care plan, which has been incorporated into XLNTbrain Sport’s complete 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.
A graduate of Georgetown University School of Medicine, Dr. Kerasidis completed his residency in Neurology and Fellowship in Clinical Neurophysiology at the Georgetown University Hospital. Dr. Kerasidis’ professional interests include cognitive neurology, sleep disorders, and behavioral correlations of EEG and cognitive event related potentials.
Training included clinical experience in epilepsy, including evaluation of medically refractory seizures for potential surgical intervention, intraoperative electrodiagnostic monitoring, evoked potentials, quantitative EEG analysis, topographical mapping, cognitive event related potential mapping, polysomnography and the diagnosis and treatment of sleep disorders.
Research included topographic mapping of EEG and cognitive event related potentials in temporal lobe epilepsy, and patients suffering from aphasia due to stroke, tumor or traumatic brain injury.
Research: Laboratory neuroscience research investigating the effects of levodopa on serotonin metabolism. Techniques acquired include stereotactic brain lesioning, high performance liquid chromatography, and data analysis.
Curriculum: General Internal Medicine (four months), Pediatrics (four months), Emergency Medicine (two months), General Surgery (one month), Pediatric Neurology elective (one month).
