Former Pat Thomas suffered CTE

BOSTON (AP) — Former NFL Pro Bowl wide receiver Demaryius Thomas is the latest in a growing list of football players diagnosed with CTE.

His family said Tuesday that researchers found that Thomas, who died in December at age 33, suffered from chronic traumatic encephalopathy. The four-time Pro Bowl wide receiver was dealing with depression, anxiety and other CTE symptoms at the time of his death.

CTE, a degenerative brain disease which can only be diagnosed posthumously, has been found in more than 100 former NFL players as well as semi-pro and high school soccer players. Hall of Fame linebacker Junior Seau had CTE when he died in 2012 of a gunshot wound to the chest.

Hall of Famers Ken Stabler, Frank Gifford and Mike Webster also were diagnosed with CTE.

Boston University CTE Center researchers discovered that Thomas was at stage 2 following a brain study through the Concussion Legacy Foundation. Thomas’ family released the findings of the study.

“Once I became aware of CTE and began to familiarize myself with the symptoms, I noticed that Demaryius was isolating himself and I saw other changes in him,” Katina Smith, Demaryius’ mother, said in a statement. “He was just so young, and it was horrible to see him struggle. His father and I hope all families learn the risks of playing football. We don’t want other parents to have to lose their children like we did.”

Stage 2 CTE is associated with “progressive behavior, cognitive and mood abnormalities.” Family members say Thomas developed depression, anxiety, panic attacks, and trouble with his memory in the years before his death. Stage 4 is the most severe stage of CTE and is usually associated with dementia.
