Doctor: O.J. Simpson likely has CTE brain damage

NEW YORK -- The doctor who inspired the movie "Concussion" has his own verdict in the O.J. Simpson case.

The New York Daily News reports Bennet Omalu believes Simpson may have sustained brain damage in an 11-year pro football career that preceded his celebrity and the disgrace that followed his 1995 murder trial.

Omalu, a forensic pathologist portrayed in the film by Will Smith, said Simpson fits the profile of the disease, which can only be diagnosed posthumously. Victims frequently exhibit erratic behavior, along with mood swings, violent tendencies, inability to concentrate, and depression.

Simpson, a running back for the Bills and 49ers, was charged with murdering his ex-wife, Nicole Brown Simpson, along with Ron Goldman.

He was acquitted of the murders in a highly-publicized 1995 trial, but was later convicted of armed robbery and kidnapping charges in 2008.

He is currently serving a 33-year sentence at a Nevada prison.
