Dr. Bennet Omalu, the renowned neuropathologist whose discovery of chronic traumatic encephalopathy in football players inspired the movie "Concussion," is willing to "bet [his] medical license" that O.J. Simpson is suffering from the disease.

"O.J. Simpson is more likely than not to suffer from CTE," Omalu told ABC News earlier this week. "I would bet my medical license on it."

Omalu has not examined Simpson personally, and CTE can only be diagnosed after death via an examination of brain tissue, but he told ABC News that he can identify the tell-tale signs of CTE's behavioral symptoms, which he said include explosive, impulsive behavior, impaired judgment, criminality and even mood disorders.

The strongest evidence that Simpson may have CTE, Omalu said, is that "he was exposed to thousands of blunt force trauma of his brain" during his playing career.
