A team of independent researchers who did not know they were studying Seau's brain all concluded he suffered from chronic traumatic encephalopathy (CTE), a degenerative disease typically caused by multiple hits to the head.
"What was found in Junior Seau's brain was cellular changes consistent with CTE," said Dr. Russell Lonser, chairman of the Department of Neurological Surgery at Ohio State University, who led the study of Seau's brain while he was at NIH.
Patients with CTE, which can only be diagnosed after death, display symptoms "such as impulsivity, forgetfulness, depression, [and] sometimes suicidal ideation," Lonser said.
"I think it's a gamble," Gina Seau said. "Just be extremely aware of what could potentially happen to your life."
