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.
Neural tissue engineering
One method to treat CNS injury involves culturing stem cells "in vitro" and implanting the non-directed stem cells into the brain injury site. Implanting stem cells directly into the injury site prevents glial scar formation and promotes neurogenesis originating from the patient, but also runs the risk of tumor development, inflammation, and migration of the stem cells out of the injury location. Tumorigenesis can occur due to the uncontrolled nature of the stem cell differentiation, inflammation can occur due to rejection of the implanted cells by the host cells, and the highly migratory nature of stem cells results in the cells moving away from the injury site, thus not having the desired effect on the injury site. Other concerns of neural tissue engineering include establishing safe sources of stem cells and getting reproducible results from treatment to treatment.
