XLNTbrain LLC provides the first complete sports concussion management program for teams and individuals of all levels. Based in Maryland, XLNTbrain was formed after more than 25 years of studying the physiology of the brain and resulting behaviors caused from various stimuli and trauma. The brain-child of Harry Kerasidis, M.D., one of only a few neurologists in the world that specialize in cognitive performance and concussions, XLNTbrain seeks to protect athletes from the dangerous consequences of undetected and untreated concussions.
