Jennifer Mathews: One clear day in October, 1996, Sandy Teepen and her husband Tom were walking to the movies, but they never made it to the theater. Sandy Teepen: A car hit me, and the impact of the car administered me or sent me into the air. Jennifer Mathews: Sandy is lucky, after a year-and-a-half of rehabilitation; she is getting her life back. Doctor David Wright says, it's not always this way. David Wright: Traumatic brain injury causes a lot of death, a lot of morbidity, a lot of mortality in this country, and there's no treatment for it. Jennifer Mathews: Doctor Wright is hoping to change that with the hormone progesterone. David Wright: What this drug does is it targets that secondary pathway. By targeting those, we now have a drug, potentially, that could halt the process of cell death. Jennifer Mathews: Progesterone seems to control inflammation that can lead to dangerous brain swelling. It also appears to slow or block the release of damaging chemicals in the brain, David Wright: We haven't seen any deleterious effects of it, and what we're seeing in the patients looks promising. Jennifer Mathews: Sandy is now back to doing hobbies that were a struggle after the accident. Sandy Teepen: It's like a room full of therapy for me. Jennifer Mathews: Therapy she is faithful for. This is Jeniffer Mathews reporting.
