Post-concussion syndrome
About 10% of people with PCS develop sensitivity to light or noise, about 5% experience a decreased sense of taste or smell, and about 14% report blurred vision. People may also have double vision or ringing in the ears, also called tinnitus. PCS may cause insomnia, fatigue, or other problems with sleep.
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.
