A Concussion is a Brain Injury!

What is a concussion?

Concussions are a type of traumatic brain injury (TBI) caused by a blow or jolt to the head. The injury can range from mild to severe and can disrupt the way a brain normally works.

An athlete does not need to lose consciousness to sustain a concussion. You cannot see a concussion but you might notice some of the symptoms right away. Other symptoms can show up days or weeks after the injury. It is best to see a health care professional if you think you might have a concussion. An undiagnosed concussion can affect your abilities at school or work and in everyday activities.


  • Nausea (feeling that you might vomit)
  • Dizziness or balance problems
  • Double or fuzzy vision
  • Sensitivity to light or noise
  • Headache
  • Feeling sluggish or tired
  • Feeling groggy or foggy
  • Confusion
  • Trouble concentrating
  • Trouble remembering

The presence of one or more of these symptoms are only signs that you may have had a concussion. But it is not a definitive sign that you have experienced a concussion.


  • Never ignore a bump to the head.
  • Tell your coach or teammates.
  • Ask to be taken out of the game.
  • Pay attention to physical changes.
  • Watch out for thinking problems.
  • Talk to your parents or teachers about the troubles you’re having.
  • See a health care professional.
  • Get plenty of rest.
  • Return to practice and play only after your brain is healed and your health care professional says it’s okay.

    Although concussions usually are caused by a blow to the head, they can also occur when the head and upper body are violently shaken. These injuries can cause a loss of consciousness, but most concussions do not. Because of this, some people have concussions and don’t realize it. ^
