MedStar National Rehabilitation Hospital
Faculty provides care for thousands suffering from mild to traumatic brain injuries. The concussion clinic at Medstar NRH focuses primarily on this form of brain injury and is regarded as one of the best in the country according to U.S. News & World Report. 75 percent of all traumatic brain injuries that occur are concussions. Traumatic brain injuries contribute to a third of all deaths in the United States with over 1.5 million brain injuries occurring each year. During their stay, patients are also educated on precautions they can take to prevent a future incidence.
Chronic traumatic encephalopathy
A putative biomarker for CTE is the presence in serum of autoantibodies against the brain. The autoantibodies were detected in football players who experienced a large number of head hits but no concussions, suggesting that even sub-concussive episodes may be damaging to the brain. The autoantibodies may enter the brain by means of a disrupted blood-brain barrier, and attack neuronal cells which are normally protected from an immune onslaught. Given the large numbers of neurons present in the brain (86 billion), and considering the poor penetration of antibodies across a normal blood-brain barrier, there is an extended period of time between the initial events (head hits) and the development of any signs or symptoms. Nevertheless, autoimmune changes in blood of players may consist the earliest measurable event predicting CTE.
