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)
Over the next few years, Omalu discovers that three other former NFL players, Strzelczyk (died 2004), Terry Long (died 2005), and Andre Waters (died 2006), had symptoms very similar to Webster's. He finally persuades newly appointed NFL commissioner Roger Goodell to allow him to present his findings before a committee on player safety. However, the NFL does not take him seriously, and he is barred from the committee meeting, forcing Bailes, a former NFL employee, to give the presentation in his place. However, the meeting is a set up, where the NFL claims that the players' head trauma was due to past injuries, having nothing to do with football. As he leaves the meeting, former NFL Players Association executive Dave Duerson angrily confronts Omalu and tells him to "go back to Africa."
