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.
Concussions in sport
In 2010, more high school soccer players suffered concussions than basketball, baseball, wrestling, and softball players combined, according to the Center for Injury Research and Policy. According to a study in the "JAMA Pediatrics" medical journal, many girls do not get necessary care and prevention regarding concussions, and 56 percent of players (or their families) reporting concussion symptoms never sought treatment.
