Many studies have demonstrated long-lasting and even permanent brain damage that can originate from just one concussion. With athletes suffering multiple repeated head traumas due to high-contact sports, the controversies over player safety and long-term health risks remain hot-button issues.

Pathologist Dr. Bennett Omalu coined the term "CTE" and published the first evidence for chronic traumatic encephalopathy after autopsying American football players. In this second of a two-part interview, he shares his perspectives on CTE in athletes and the lifelong dangers of contact sports.
