About Concussions

A concussion is a traumatic injury to the brain that alters mental status or causes other symptoms. Many people assume they do not have a concussion if they have not lost consciousness.

Significant injury can occur without losing consciousness at all. A player will often say “I just got my bell rung” when a blow to the head causes ringing in the ears, but those symptoms are often consistent with concussion.

Diagnosing a concussion
When concussion is suspected, a certified athletic trainer or the team physician should immediately perform an initial evaluation, including:

  • Symptoms list review
  • Focused neurological exam and balance assessment.
  • Focused orientation exam that tests short-term memory recall such as the event, play, opponent, score, or last meal
  • Focused orientation exam that tests long-term recall such as name, birth date, place of birth
  • Assessment of athlete’s ability to stay attentive to a complex task such as reciting months backwards

If left undiagnosed, a concussion may place an athlete at risk of developing second impact syndrome—a potentially fatal injury that occurs when an athlete sustains a second head injury before a previous head injury has completely healed.

Signs/symptoms of a concussion
Concussion symptoms include the following:

  • Balance problems
  • Difficulty communicating, concentrating
  • Dizziness
  • Drowsiness
  • Fatigue
  • Feeling emotional
  • Feeling mentally foggy
  • Headache
  • Irritability
  • Memory difficulties
  • Nausea
  • Nervousness
  • Numbness or tingling
  • Sensitivity to light or noise
  • Visual problems — blurry or double vision
  • Vomiting
  • Pressure in head, neck pain, feeling slowed down
  • Not feeling right

Safe return to play

All athletes who sustain a concussion should undergo an evaluation by a qualified healthcare provider before returning to play. Athletes can return to play after they have completed a 5–6 step “Return to Play” program and have started a “Return to Academics” program. Athletes can return to play after they are completely free of all symptoms of a concussion and remain symptom free during and after physical testing.

Unfortunately, it is difficult to determine if the brain has healed from a concussion; even after all symptoms have resolved, healing may not be complete. Neurocognitive testing can be a very helpful tool in determining brain function. With a comparison to a baseline test, this evaluation can be used in conjunction with a physician’s examination to reduce future risks.

Baseline testing collects data on an athlete’s cognitive and physical abilities prior to suffering the concussion. Baseline testing can include a neurocognitive evaluation (usually by computer) that tests multiple areas of brain function, including memory, problem solving, reaction times, and brain processing speeds. Symptom checklists, sideline assessment tools such as the Sideline Concussion Assessment Tool (SCAT-5), and balance testing are other examples of baseline evaluations that may be helpful.
