Head Injuries In SportsJOHN GONOUDE
Mild traumatic brain injuries are an inherent risk of contact sports, and yet they have continually been misunderstood or regarded as a sign of weakness in the integrity of an athlete. All who are involved in such activities must be educated on the signs, symptoms, and risks of repetitive head injuries in order to ensure the safety of our athletes through proper management and diagnostic skills.

Features of a Concussion
• Vacant stare• Delayed verbal and motor
responses• Disorientation• Confusion and inability to
focus attention• Incoordination• Slurred and incoherent
speech• Emotions out of proportion• Memory deficits• Any period of
unconsciousness
American Academy of Neurology
SYMPTOMSEarly Symptoms
• Headache• Dizziness• Lack of awareness of
surroundings• Nausea or vomiting
Late Symptoms
• Low-grade headaches• Lightheadedness• Poor attention and
concentration• Memory dysfunction• Easy fatigability• Irritability and low frustration
tolerance• Intolerance of bright lights or
difficulty focusing vision• Intolerance of loud noises• Anxiety or depressed mood• Sleep disturbance
American Academy of Neurology
During a concussion, the brain develops inabilities in regulating
blood supply and making energy.

(PLASTICITY)
• Neurotransmitters bind on to receptors and change the receptors– Susceptible to
glutamate• Excitotoxic
death

“IF PEOPLE SAY THERE IS NO CORRELATION BETWEEN WHAT HAPPENED TO THEM AND PLAYING; BULLS***, BULLS***. AND PEOPLE CAN CALL ME ANYTHING THEY WANT. THEY CAN CALL ME A MALCONTENT, A BABY; WHATEVER THE F*** YOU WANT TO CALL ME. BUT NOBODY IS GOING TO SHUT ME UP FROM TALKING ABOUT WHAT I KNOW.”
HARRY CARSONESPN, Outside the Lines
POST-CONCUSSION
SYNDROME• Condition may take
days, weeks, months, or even years to recover from
• Symptoms include prolonged cases of physical, cognitive, emotional, and behavioral issues
University of Buffalo, Current Treatment Options in Neurology
DEPRESSION
Persistently sad or empty mood, low energy level, unusual fatigue, headaches, unresponsive chronic pain

Let’s put a concussion into perspective.

“I don’t know how much sense that makes, because we’re dealing with the same organ. No cardiologist ignores a ‘mild’ heart attack. He doesn’t say to his patient, ‘don’t worry about exercise or your diet unless the heart attack is severe.’ He still treats him as if he has had a heart attack. Yet we don’t treat a concussion in the same way as we do a brain injury. For some reason we tell people, ‘you’re fine,’ when we know they aren’t.”

It is estimated that between 1.6 to 3.8 million concussions occur every year in the United States. In 2008, 126,926 sports-related concussions were treated in United States hospital emergency rooms. 47,807 (37.6%) of those concussions occurred in children under the age of 14.

HEAD IMPACT TELEME
TRY SYSTEM(HITS)
Journal of Athletic Training
Head Impact Telemetry System (HITS)• Evaluates regions of the head that are most
susceptible to damage• Accounts for linear & rotational acceleration, jerk,
force, impulse, and direction• Has only been used as a tool for research, but may
have a future in diagnostics
Journal of Athletic Training
From 1945-1999, 491 head-related football fatalities occurred in high school, collegiate, professional, and recreational levels.

TEN POINT PLAN TO SAVE FOOTBALL
1. Reevaluate how the game is practiced
2. Encourage mandatory brain trauma education
3. Reevaluate protective equipment
4. Develop better methods of diagnosis
5. Develop better methods of management
6. Consider minimum medical resources
7. Reevaluate techniques of tackling and blocking
8. Reevaluate the rules9. Reevaluate rule
enforcement and role of referees
10.Reconsider the culture of the game

Upper Merion Concussion Survey63 out of 100 student athletes responded; 38 seniors, 15
juniors, 4 sophomores, and 6 freshmen.
78 total concussions were reported by 39 out of 63 (61.9%) student athletes.
Only 37 out of the 78 (44.8%) concussions were reported to have been diagnosed by an athletic trainer.
25 out of 63 (39.7%) student athletes said they would not tell a coach or athletic trainer if they had a concussion.
9 out of 39 (23.1%) student athletes reported that they have had three or more concussions during their athletic careers.
Luck of the Draw Foundation
CONCLUSION
• Concussions should be treated as a brain injury
• Guidelines at all levels of play must be set in order to best protect our athletes
• Athletes, parents, and coaches must be educated on the signs, symptoms, and risks of mild traumatic brain injuries
• No child’s life should be put at risk to perform on the playing field
