Citing rapid behavioral changes that occurred in his 20s, some people have posited that Boston Marathon bomber Tamerlan Tsarnaev could have been more easily radicalized to the point of carrying out acts of terror because of brain injuries he may have sustained in his fledging boxing career.
Researchers say that the possibility that brain injuries played a role is worth looking at, but not likely.
From The Boston Globe:
Two pioneering researchers of brain disease among athletes in violent sports recommended Saturday that investigators conduct special autopsy tests on amateur boxer Tamerlan Tsarnaev to determine whether the Boston Marathon bombing suspect could have been affected by boxing-related brain damage.
The researchers expressed serious doubt the disease — chronic traumatic encephalopathy, or CTE — could have factored in the wave of violence that led to Tsarnaev’s death early Friday in a firefight with police.
But they suggested investigators would be remiss if they did not autopsy Tsarnaev’s brain for signs of CTE. The disease can only be diagnosed through post-mortem forensic tests of the brain.
