3. What is a concussion? • A concussion is an injury to the brain that affects the brain’s ability to function properly. • According to the Concussion in Sport Group, these injuries are defined as “a complex pathophysiological process affecting the brain, induced by traumatic biomechanical forces.”

4. How many people get concussions? • The Center for Disease Control and Prevention estimated that approximately 1.6 to 3.8 million sport-related concussions occur annually in the United States. • 18.2% of them were a sport-related concussion.3 In high school athletics • 8.9% of all injuries suffered were concussion. • Of all the high school sports, the most concussions are seen in football, and soccer. • In football specifically, 67.6% of the concussion suffered were caused by tackling or being tackled. • Of the different positions, linebackers and running backs suffered more concussions than compared to the other positions. • In soccer, the most common cause of a sport-related concussion in both boys and girls is heading the ball.

8. Red Flag" for Immediate Referral to Emergency Room • "Brain Function Deteriorating • Loss of Consciousness • Decreasing Level of Consciousness • Difficulty Breathing • Mental Status Changes • Pupils are Unequal • Seizures

9. What do I do if my athlete has a concussion? • If you suspect a concussion, it is recommended that the athlete be immediately removed from competition or practice. • No athlete should be allowed to return to activity while still experiencing symptoms. • The athlete should be referred to a medical professional with a background in sport-related concussion treatment. • If the athlete is exhibiting signs or symptoms that warrant immediate medical attention, 911 should be activated and an emergency action protocol initiated. • If the athlete has any “Red Flag” Signs and Symptoms you should transport them immediately to an emergency room.

14. Cognitive and Physical Evaluation • Maddocks Score • 1. At what venue are we at today? (0 or 1) • 2. What half is it now? (0 or 1) • 3. Who scored last in this game/match (0 or 1) • 4. What team did we play last week/game (0 or 1) • 5. Did your team win the last game? (0 or 1) • Maddocks Score of 5 • Cognitive Assessment • Orientation Exam (5 questions) • Immediate Memory (3 trials of 5 words) • Concentration Exam (5 trials)

17. Concussion Return to Play Guidelines • It is very important to NEVER return to play (physical education class, sports, practice, or game) while still experiencing symptoms of a concussion. • The same sentiment can be spoken for cognitive activities (school work, video games, text messaging, etc).

18. Gradual Return to Physical Activity • While most athletes can return to play (physical activity) in about 7-10 days, some may take longer for their symptoms to subside and may have a more prolonged absence from sports. • Once all symptoms subside and the scores on any additional objective clinical tests improve, the athlete may begin a return-to-play progression, supervised by a healthcare professional. • This progression often takes place over a period of 4-6 days and allows the athlete to gradually return to physical activity, and eventually sport.

19. Typically, each phase should occur in a 24 hour period, allowing for the athlete to rest and the observation of the onset of any delayed post-activity signs and symptoms. • If any post-concussive symptoms do occur along the stepwise progression, the athlete is required to drop back to the previous asymptomatic stage and allowed to return to the return to play protocol after a rest period of 24 hours.

20. Gradual Return to Physical Activity Protocol

21. Gradual Return to Physical Activity

22. Gradual Return to Cognitive Activity • Equally as important as physical rest, for complete recovery, is cognitive rest. • Athletes sustaining a concussion who are reporting numerous symptoms such as headache, dizziness, fatigue, and inability to concentrate should be encouraged to limit scholastic activities and other cognitive stressors. • Daily activities such as reading, watching television, text-messaging and playing video games should also be avoided to allow a period of cognitive rest.
