Will Smith stars in the new film CONCUSSION, based on a 2009 exposé in GQ magazine, about a South African doctor named Bennet Omalu and his discovery of a disease called CTE (chronic traumatic encephalopathy). Previously known as “dementia pugilistica,” CTE results from blows to the head over a period of time that cause traumatic brain injury, whose cognitive, emotional, and behavioral symptoms do not become noticeable until years later. Along with his colleagues at the University of Pittsburgh, Dr. Omalu was the first to publish findings about NFL football players in America (“Chronic Traumatic Encephelopathy in an NFL Football Player,” Neurosurgery, 2005) , conducting an independent and self-financed autopsy of the brain of a deceased offensive lineman, whose brain looked normal at first but contained large accumulations of tau protein, also associated with Alzheimer’s disease. The tragic suicides of beloved athletes such as Junior Seau, who suffered from the disease, Unfortunately, definitive tests can only be made post-mortem, and the NFL, with a record $13 billion in revenue this year, is a classic American institution, as ignorant, greedy, and morally corrupt as the United States Congress. The film is directed by Ridley Scott (see Blade Runner, Thelma and Louise, Gladiator, and The Martian) and also features Gugu Mbatha-Raw, Alec Baldwin, Luke Wilson, Albert Brooks, and Arliss Howard.
