Researchers who study chronic traumatic encephalopathy, or CTE, have long wondered why some people are hit harder by the degenerative brain disease.
CTE is currently diagnosed only after death but the condition is associated with repeated hits to the head, often experienced by contact sports athletes. CTE has afflicted some of the world’s popular athletes, which include football player Aaron Hernandez.
His family has accused the National Football league of failing to protect him from a brain injury that may have contributed to him committing suicide.
Researchers observed that some individuals develop more severe forms of CTE than others. Hernandez has been found to have one of the most severe cases of CTE among the dead athletes whose brains were studied by researchers from Boston University.
