Post-concussion syndrome
Post-concussion syndrome, also known as postconcussive syndrome or PCS, is a set of symptoms that may continue for weeks, months, or a year or more after a concussion – a mild form of traumatic brain injury (TBI). The rates of PCS vary, but most studies report that about 15% of individuals with a history of a single concussion develop persistent symptoms associated with the injury. A diagnosis may be made when symptoms resulting from concussion last for more than three months after the injury. Loss of consciousness is not required for a diagnosis of concussion or post-concussion syndrome.
Concussion (2015 film)
Three years later, Omalu is vindicated when Duerson commits suicide due to growing cognitive problems. In his suicide note, Duerson admits that Omalu was right. Omalu is allowed to address an NFLPA conference on concussions and CTE. He informs them that he once wished he had never known Mike Webster, but by knowing him, he has the responsibility to inform NFL players of the true risks that they take by playing. He says that he holds no resentment for the NFL and tells them to forgive themselves and be at peace. Amid growing scrutiny from Congress, the NFL is forced to take the concussion issue more seriously, and in 2011, NFL players sue the league for not properly informing them of the risk of CTE. Omalu is offered a job as chief medical examiner for the District of Columbia, but as explained in closing title cards, turns it down, remaining with Prema and their two children in California, where he became a U.S. citizen in February 2015. A final montage includes reports of Junior Seau's suicide in 2012, and the subsequent lawsuit brought by players.
