Concussion: By the Numbers

•CDC estimates reveal that 1.6 million to 3.8 million concussions occur each year•5-10% of athletes will experience a concussion in any given sport season•Fewer than 10% of sport related concussions involve a Loss of Consciousness (e.g., blacking out, seeing stars, etc.)•Football is the most common sport with concussion risk for males (75% chance for concussion)•Soccer is the most common sport with concussion risk for females (50% chance for concussion)•78% of concussions occur during games (as opposed to practices)•Some studies suggest that females are twice as likely to sustain a concussion as males•Headache (85%) and Dizziness (70-80%) are most commonly reported symptoms immediately following concussions for injured athletes•Estimated 47% of athletes do not report feeling any symptoms after a concussive blow•A professional football player will receive an estimated 900 to 1500 blows to the head during a season•Impact speed of a professional boxers punch: 20mph•Impact speed of a football player tackling a stationary player: 25mph•Impact speed of a soccer ball being headed by a player: 70mph

PARTS OF THE BRAINFrontal Lobe: thought, reasoning, planning, emotions, problem solving

Parietal Lobe: perception of touch, pressure, temperature and pain; spatial processing

Temporal Lobe: memory, perception of hearing; language; recognition

Occipital Lobe: vision

Cerebellum: balance, coordination, timing

Cerebellum: balance

WHAT TO DO

Watch player after a hit to head

IF THERE ARE ANY SYMPTOMS, REMOVE FROM PLAY

Sideline Assessment--ask questions

WHEN IN DOUBT, SIT THEM OUT

Seek medical help if needed or if symptoms worsen
