Definition of Concussion
- Caused either by a direct blow to the head, face, neck or elsewhere on the body with a resultant force transmitted to the brain.
- Typically results in the rapid onset of short lived changes in neurological function that resolves spontaneously.
- May result in structural brain changes, but the symptoms largely reflect a functional disturbance rather than a structural injury.
- Usually follows a progressive course of improvement.
- Imaging studies (brain CT/MRI) are usually normal.
Signs and Symptoms of Concussion
- Appears dazed or stunned
- Confused about assignment
- Forgets plays
- Is unsure of game, score, or opponent

- Balance problems or dizziness
- Double vision
- Sensitivity to light or noise
- Feeling sluggish
- Feeling “foggy”
- Concentration or memory problems
- Change in sleep pattern (appears later)
- Feeling fatigued
Common symptoms of concussion from a series of injured high school athletes
- Three most common symptoms:
- Headaches (55%)
- Dizziness (42%)
- Blurred vision (16%)
- 46% experienced either cognitive or memory problems
- 9% had loss of consciousness (“knocked out”)
Do you have to be “knocked out” to have a concussion?
- In fact, only a SMALL number of concussed athletes were “knocked out”
- Many studies have now shown that amnesia (inability to remember) is a much more common sign of concussion and ALWAYS indicates that a brain injury has occurred
In general and on average, the short term effects of concussion resolve within:
- 7 days for professional athletes
- 7-10 days for collegiate athletes
- 7-14 days for high school athletes
- 7-21 days for younger athletes
- 90% of athletes with sport-related concussions recover within a month
