What is a Concussion?According to the Centers for Disease Control and Prevention (CDC), a concussion is a type of traumatic brain injury caused by a bump, blow or jolt to the head, or a hit to the body that causes the brain to move or shift in the skull and causes a functional disturbance and chemical changes to brain cells. Concussions typically result in the rapid onset of signs and symptoms, although in some cases symptoms may evolve over minutes to hours.
Potential Concussion Signs and Symptoms:
- Headache or feeling "pressure in the head"
- Difficulty remembering events just before or after a hit or fall
- Appearing dazed or stunned

- Moving clumsily or answering questions slowly
- Concentration or memory problems
- Just not "feeling right" or "feeling down"
- Showing mood, behavior, or personality changes
- Feeling sluggish or foggy
- Nausea or vomiting
- Balance problems or dizziness
- Double or blurry vision
- Bothered by light or noise
