Concussion

 

 

Concussion is the sudden but short-lived loss of mental function that occurs after a blow or other injury to the head. It is the most common but least serious type of brain injury.

​

Signs and symptoms of a concussion may include:

​

• headache or a feeling of pressure in the head

• temporary loss of consciousness

• confusion or feeling as if in a fog

• amnesia surrounding the traumatic event

• dizziness or "seeing stars"

• ringing in the ears

• nausea

• vomiting

• slurred speech

• delayed response to questions

• appearing dazed

• fatigue

   

A person with a single, isolated concussion generally has a very good recovery outcome with few long-term effects.
