Dave Duerson killed himself to advance the cause of chronic traumatic encephalopathy. He shot himself in the chest and requested his brain be tested for this disease. The results were released today and he did have a progressive condition.
The doctor, Dr. Ann McKee, said:
Dave Duerson had classic pathology of CTE and no evidence of any other disease, and he has severe involvement of all the structures that affect things like judgment, inhibition, impulse control, mood and memory. The likelihood is that if he hadn’t had the CTE, he wouldn’t have developed those symptoms that he was experiencing at the end of his life and perhaps he wouldn’t have been compelled to end his life.
