What are the risks of returning to play too early?
A player returning too early could suffer from "second impact syndrome," which can be fatal. A second blow to the head, even a minor one, can cause a loss of control of blood flow to the brain. Never return to a sports activity until you are cleared by a doctor.
Are there any lasting effects to a concussion?
Most people get better after a concussion without any permanent damage. Some people have signs of concussion for weeks or months. Repeated concussions can cause permanent damage. After several concussions, your doctor may talk with you about changing sports.
