The National Football League has placed its strictest rules yet on managing concussions. What is the medical profession to make of such a policy and what are its broader implications for players' long-term health and for future medical research? Dr. Julian Bailes is a founding member of the Brain Injury Research Institute, which is affiliated with the Blanchette Rockefeller Neuroscience Institute at West Virginia University and possesses a brain and tissue bank that houses 20 brains for future research. He is also professor and chairman of the department of neurosurgery at West Virginia University School of Medicine. Dr. Bailes tells host Bruce Japsen about important research into the short and long-term impact of brain injuries.
