Ex-wrestler Kevin Nash will donate brain to CTE study

Former professional wrestler Kevin Nash will donate his brain and spinal cord to CTE research following his death.

Boston University and the Concussion Legacy Foundation, which is headed by former WWE wrestler Chris Nowinski, will receive Nash's brain.

"Chris Nowinski started the program, and I've had several concussions throughout my life and had scans done and stuff and knew that somewhere down the line, I've already had short-term memory problems," Nash told ESPN. "I decided to go ahead. The only way you can diagnose this is after you're dead.

"I went ahead and gave my spinal cord and my brain to the study, and I carry a card in my wallet that my brain and spine goes to them. It's in my will. Of course, my wife's aware of it."

The 56-year-old former world champion said he's had brain scans that show abnormalities, though there's no evidence of shrinkage.

He added he's become more emotional in recent years, which he attributes to the numerous concussions he suffered in the ring.

Nash also said his short-term memory has weakened, but he's not sure if that's related to prior brain trauma.

CTE, a degenerative brain disease, has become particularly prevalent among former professional wrestlers and football players.

Former U.S. women's soccer star Brandi Chastain also announced her intention to donate her brain for CTE research after she dies.

Nash was inducted into the WWE Hall of Fame in 2015.
