Gunman at NFL Headquarters had CTE

Known as C.T.E., the disease can be diagnosed only posthumously. It has been found primarily in older athletes years after they stopped playing, though a smaller but growing number of younger athletes — even those who don’t play beyond high school — have been found with the disease. Mr. Tamura was 27 and played football only through that level.
The condition of Mr. Tamura’s brain revives questions about the possible long-term dangers of playing tackle football, even at only the youth level.

The gunman who killed four people in a Midtown Manhattan office building in July had chronic traumatic encephalopathy, the degenerative brain disease linked to repeated head injuries sustained in football and other contact sports, according to the New York City medical examiner’s office.

Shane Tamura’s brain tissue was found to have “unambiguous diagnostic evidence” of CTE, according to the New York City Office of Chief Medical Examiner.
In a statement, the NFL pointed to the medical examiner’s claim that the science around CTE “continues to evolve” and the physical and mental symptoms are still being studied.
