The fall season of high school sports is already underway, and with sports comes the risk of concussions. If a child gets a concussion, removing him or her from play is a key part of treatment and recovery.

Mayo Clinic experts have developed a screening program that involves testing brain function skills, such as memory, reaction time and recall before the sports season begins. Then, if concussions happen, retesting can determine when it’s safe for athletes to return to the game.

Fall sports are in full play at many schools. All kids are at risk of concussion, especially those in contact sports.

“A concussion happens when there’s a force transmitted to the brain,” says Dr. Jennifer Maynard, a Mayo Clinic sports medicine specialist.

Maynard helped initiate a preconcussion screening program at Mayo Clinic, “Follow my finger.”

Before athletes start, they go through testing to determine what’s normal. Then, if they get a concussion, they’re screened again and can’t return to play until their test scores are back to baseline.

“When in doubt, sit them out, because you don’t want to put them at risk for getting a subsequent injury that could lead to longer-lasting effects,” says Maynard.

Symptoms of concussion include headache, blurry vision, confusion, balance problems, sleep disturbances and emotional issues, such as anxiety and sadness. If you suspect a concussion, pull the child from play, and follow up with a health care provider.
