Signs & Symptoms
of a Concussion

Concussions are often very difficult to detect because the injury is not visible.

It is also possible that typical symptoms of a concussion only appear after a few days.

Among other things, restricted cognitive and physical abilities, impaired consciousness, dizziness and balance disorders, pupils of different sizes, memory gaps, severe headaches, nausea, and nausea suggest a concussion.
The following is a detailed listing of symptoms, one or more of which could indicate a concussion.

What should I do?

Any sporting activity must be stopped immediately.

Make sure the player is assessed as soon as possible by a medically trained person who has had concussion experience. Never try to judge the severity of the injury yourself.

Notify the emergency contact and officials of a possible concussion.

You or your child has sustained a concussion?

If you believe you or your child has sustained a concussion, consult your family or sports physician as soon as possible for medical evaluation.

If you believe you or your child has sustained a concussion, consult your family or sports physician as soon as possible for medical evaluation. Most sport-related concussion injuries do not require emergency care. However, it is important that the injured party remains under close observation for the first few hours (and even days) following the injury, and the individual should not be left alone or allowed to operate a motorized vehicle. Emergency evaluation is warranted in situations of deteriorating mental status. The following symptoms may indicate that the athlete has sustained a more serious and/or life-threatening injury


  • Increasing confusion
  • Difficulty recognizing people or places
  • Worsening headaches
  • Nausea, vomiting
  • Excessive drowsiness, lethargy
  • Slurred speech
  • Convulsions/seizures

At the doctor’s office?

At the doctor’s office, you will be asked to describe the
symptoms you’ve experienced, and you may undergo several tests to determine if a concussion is suspected.

These tests may include a variety of the following:

  • Eye exam
  • Balance assessment (with your eyes open, and then closed)
  • Coordination testing (for example, bringing your index finger to your nose several times)
  • Gait evaluation (observing you walk, watching you walk heel-to-toe)
  • Blood pressure assessment
  • Listening to your heart and chest
  • Checking your neck for pain, tenderness, or limited motion
Please note: The previous list is not exhaustive nor does having one or more of these symptoms mean that someone has a concussion.
It is merely a guide to possible concussive symptoms. It is important to seek medical attention immediately to receive a diagnosis.
Medical doctors specializing in concussions may complete a more advanced neuropsychological assessment including computerized cognitive testing. Although standard imaging studies such as X-rays, CTs and MRIs do not typically show any abnormalities following a concussion, the physician may order these tests to rule out other trauma to the skull or neck.

Unfortunately, there is no “gold standard” for the diagnosis of concussion. No single test exists to determine definitively that a concussion has occurred. The physician has to integrate the results from the various tests to establish the overall picture. If there is a typical mechanism of injury consistent with concussion and the athlete reports any one or more of the known symptoms, a concussion diagnosis is given. However,
not all medical doctors and health professionals are up to date on diagnosis and the current management strategies. If you think your doctor’s visit was not informative or thorough, seek a second opinion.

In the event that you or your child requires more specialized assessment, you may be referred to a medical specialist such as a sport physician, neurologist, pediatrician or neuropsychologist who has expertise in concussion and brain injury management. This measure is not always required initially and may be reserved for situations of prolonged recovery or severe impairment.
