How to identify a concussion and when it is necessary to seek medical attention

A concussion is a type of brain injury caused by a blow to the head.  It can be categorized as a minor injury requiring minimal treatment, or a major injury that requires immediate medical attention.  A concussion can affect how the brain works for a long period of time and can be accompanied by a wide variety of symptoms. The most common symptoms of this injury include a bad headache, changes in alertness, memory loss, confusion, irritability, fatigue, or a short term loss of consciousness. Minor concussions may not lead to loss of consciousness.  In fact, a person can have a minor concussion and not realize it. 


A concussion can affect how the brain works for a long period of time.

If any of the following symptoms are observed, seek immediate medical attention as a more serious brain injury has occurred and it should be treated as an emergency:

  •  Changes in alertness and consciousness
  •  Confusion that does not go away
  •  Seizures
  •  Muscle weakness on one or both sides
  •  Pupils of the eyes that are not equal in size
  •  Unusual eye movements
  •  Repeated vomiting
  •  Walking or balance problems
  •  Unconsciousness for a longer period of time or that continues (coma)
