Brain degeneration can cause:CTE can only be diagnosed after death. Dave Duerson suffered 10 known concussions during his career. His playing career ended in 1993. He complained of memory loss and erratic behaviours.According to Ann McKee, the neuropathlogist who conducted the anaylsis of Duerson's brain and co-director of the Boston University School of Medicine Center for the Study of Traumatic Encephalopathy:
- memory loss
- impaired judgment
- impulse control problems
- progression dementia (eventually)
" Dave Duerson had classic pathology of CTE and no evidence of any other disease...He had severe involvement of areas that control judgment, inhibition, impulse control, mood and memory."The Boston University Center has now studied the brains of 15 deceased NFL players, and all but one had CTE.A Time.com article, "Dave Deurson's Suicide Raises Awareness of Brain Injuries" features statements by Chris Nowinski, co-director of Boston University's Brain Research Center:Nowinski mentions that that Boston University researchers found early evidence of CTE in an 18 year old who only played football through high school. At least two college players who committed suicide in April 2011 at age 21 showed signs of CTE.
"What Dave Duerson's death means is that we've got a lot of people out there suffering silently...The reality is, if they have this disease, we're not sure what they're going to do next." - Chris NowinskiThe Time.com article also featured remarks from, Kyle Turley, formerly of the New Orleans Saints, St. Louis Rams and Kansas City Chiefs suffered multiple concussions in his 8 year NFL career. He too contemplated suicide. He takes medication to control his moods. He had this to say:
"We all see it..Just being down there at this year's Super Bowl and looking those former players in the eyes, it was a sobering experience. They all had the same look. It says, 'Only we know what is happening to us.' It's a scary thing."Dave Duerson told his ex-wife that he was suffering from short-term memory loss, blurred vision and pain on the left side of his brain. Did he fear what was happening him? (He took precautions to make sure his brain was intact at the time of his death). Did he know what was happening to him? We will never know.We only know he wanted his brain donated as part of a research project and now we know he suffered from the fateful disease, chronic traumatic encephalopathy.
