Kevin Nash has revealed he will donate his brain and spinal cord to the CTE Center at Boston University and the Concussion Legacy Foundation after his death, according to a report from accmag.com.

“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 said. “I decided to go ahead. The only way you can diagnose this is after you’re dead.”
