Concussions and NFL: How the name CTE came about
By Bennet Omalu
(CNN)When I read Mike Webster's file before I began his autopsy, I knew he was more than a 50-year-old heart attack victim. His file and the television reports of the death of the former Pittsburgh Steelers center described a long, steep fall into bizarre behavior. I suspected he suffered from some sort of brain disorder.
The potential diagnoses on my mind were post-traumatic encephalopathy (encephalopathy means brain disease, damage, or malfunction), Alzheimer's disease, dementia pugilistica, aka punch drunk syndrome, and/or schizophrenia.
At this time there was no disease that I was aware of that was called
chronic traumatic encephalopathy, or CTE. Dementia pugilistica was unlikely since he was not a boxer. Schizophrenia was unlikely since he did not have any diagnosis of that disease in the extensive pre-mortem clinical workup that he had. Alzheimer's disease was less likely given his age.
Post-traumatic encephalopathy was about the only remaining diagnosis I had in mind while I performed the autopsy and considered the case. Based on what I knew about Webster's career and his post-football behavior, I expected to see the residual damages of recurrent contusions and necrosis (death of body tissue), and even atrophy of a lobe in his brain, which would be characteristic of post-traumatic encephalopathy.
The story of the discovery of Webster's brain disorder is worth telling, not only because of the upcoming release of the film "Concussion," but also because some detractors have raised questions that I believe are unjustified.
