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.
National Football League controversies
The league has also been criticized for its efforts in preventing concussions, in which eight former players have died, and have also had concussions throughout their careers. In 1994, former commissioner Paul Tagliabue created the Mild Traumatic Brain Injury Committee in order to study the effects of concussions on players. With the suicide of linebacker Junior Seau in 2012, concerns arose about the connection between player deaths and concussions. As a result, on April 9, 2013, a lawsuit involving 4,100 plaintiffs and 222 consolidated lawsuits against the NFL will be held by a federal court.
