Studies are continually showing that repeated head trauma suffered by athletes have negative long-term consequences.
A recent study of the brains of former NFL football players showed that 95 percent of those examined suffered from a neurodegenerative disorder known as CTE. Eight-one percent of former college football players reportedly had the same disorder.
CTE is associated with aggression, depression and memory loss, according to the Daily Mail.
“It’s amazing what they do to their brains,” Ann McKee, a Boston University School of Medicine professor of neurology and pathology, told the MIT Technology Review.
McKee and her colleagues performed this new study, highlighted by the MIT Technology Review, and found a correlation between repeated head trauma suffered in contact sports and CTE.
CTE, or Chronic Traumatic Encephalopathy, was first discovered by Nigerian-American neuropathologist Bennet Omalu, who published his findings in 2005 after studying football player Mike Webster’s brain, the Daily Mail reports.
McKee’s study was performed by several scientists at Boston University, where the brains of 92 former NFL players and 55 former college players were examined.
The Daily Mail notes that the study is biased, since many of the brains used were donated by families who already suspected brain damage.
