Benoit Had Brain Damage [David Stefanini]

This from the Associated Press:

Pro wrestler Chris Benoit suffered head trauma from his years in the ring that could help explain why he killed his wife, son and himself, a doctor who studied his brain said Wednesday.

The analysis by doctors affiliated with the Sports Legacy Institute suggests that repeated concussions could have contributed to the killings at Benoit's suburban Atlanta home, though there was no way to know for sure.

"Whether it is the sole factor, I believe, is speculation, and I will not go there," said Dr. Robert Cantu, a member of the Waltham, Mass.-based institute, which researches the long-term effects of concussions.

The level of brain damage Benoit had could have caused depression and irrational behavior, said Cantu.
