Can concussions lead to chronic traumatic encephalopathy (CTE)?

Scientists aren't yet sure why, but having several concussions makes you more likely to develop a degenerative brain disease. In this video, Walter J. Koroshetz, MD, director of the NINDS, explains what this disease is and how it occurs.

Brain injuries and exposure to certain chemicals may increase your chances for the disease later in life.
