Will Smith's new movie "Concussion" highlights the discovery of how brain injuries in professional football players is life-altering. Dr. Bennet Omalu made the discovery many years ago, forcing the NFL to face the truth about head injuries suffered by NFL athletes. The NFL tried to discount the severity of head injuries for many years, but Dr. Omalu's research revealed just how damaging repeated head injuries can be. He discovered chronic traumatic encephalopathy (CTE) in 2002 while performing an autopsy on Mike Webster, former NFL player. Dr. Omalu recognized Mike Webster's bizarre behavior toward the end of his life as related to brain trauma: drug addiction, severe depression, losing all his money, severe memory problems. Dr. Omalu experienced a lot of resistance and criticism, even to this day, for revealing an ugly truth about contact sports that make up the core of American society. This new movie will explore Dr. Omalu's side of the story.
