What is a concussion?

Millions of concussions occur on a annual basis. A concussion is defined as any injury to the brain that can alter the way the brain functions. Concussions can occur from not only high velocity injuries but from glancing and otherwise un-assuming blows. Concussion symptoms can vary from individual to individual just as length of recovery can vary as well. By definition, a concussion is not a life-threatening injury, but it can cause both short-term and long-term problems.

  • Dizziness
  • Nausea/Vomiting
  • Blurred vision
