The National Institutes of Health studied his brain

Junior Seau, one of the NFL's best and fiercest players for nearly two decades, had a degenerative brain disease when he committed suicide last May, the National Institutes of Health told The Associated Press on Thursday.

Results of an NIH study of Seau's brain revealed abnormalities consistent with chronic traumatic encephalopathy (CTE).
