High School Concussions More Expertly Diagnosed

iStock/Thinkstock(COLUMBUS, Ohio) -- Although a national study finds that concussion rates among high school athletes rose twofold from 2005 to 2012, the news isn't quite as bad as it sounds.

Joseph Rosenthal, the Ohio State University professor who led the study, explains the increase probably means that concussions are being more expertly diagnosed than prior to 2005.

Overall, the rate increased from .23 to .51 concussions per 1,000 athletes participating in either one competition or practice, which translates into approximately 4,024 players in nine high school sports.

Rosenthal said, “It's scary to consider these numbers because at first glance it looks like sports are getting more dangerous and athletes are getting injured more often.”

However, he explains that it really has to with more awareness of the problem of head trauma. Symptoms include dizziness, lightheadedness, confusion, headache and vision change.

In recent years, there has been education about concussions and guidelines set as to how long to keep a player who may have suffered a head injury on the sidelines.
