What is a Concussion?


A concussion is a form of a brain injury, usually caused by a direct or indirect blow to the head, face, or jaw. As a result of the injury, brain function changes and the brain works less optimally. A loss of consciousness is not a requirement for diagnosing a concussion. In reality, less than 20% of concussions involve a loss of consciousness.

What are the symptoms of a concussion?

A concussion produces a wide variety of symptoms and individual responses. In addition, the appearance of symptoms may vary from several minutes to hours after the initial injury.

Common symptoms include:

  • Headache

  • Dizziness

  • Neck Pain

  • Loss of balance

  • Poor concentration and coordination

  • Feeling "foggy"

  • Confusion

  • Blurred or double vision

  • Ringing in ears

  • Vacant stare

  • Fatigue

  • Nausea or vomiting

  • Poor memory

  • Difficulty falling asleep

Due to the variability of a concussion’s appearance, a general rule to follow is if the incident involves at least one symptom and a potential head injury, then a concussion assessment by a medical doctor would be recommended. After a medical evaluation by a physician, subsequent assessments can be carried out at KW Health Connection.
