Signs and Symptoms of Concussion

concussionThe signs and symptoms of a concussion can be subtle and may not appear immediately. Symptoms can last for days, weeks or longer.

The two most common symptoms are confusion and amnesia (loss of memory). The amnesia, which may or may not be preceded by a loss of consciousness, almost always involves the loss of memory of the impact that caused the concussion.

Other immediate signs and symptoms of a concussion may include:

  • Headache
  • Dizziness
  • Ringing in the ears 
  • Nausea or vomiting
  • Slurred speech

Some symptoms of concussions don't appear until hours or days later. They include:

  • Mood and cognitive disturbances
  • Sensitivity to light and noise 
  • Sleep disturbances

What to Look for in Infants and Toddlers
Head trauma is very common in young children. But concussions can be difficult to recognize in infants and toddlers because they can't readily communicate how they feel. Nonverbal clues of a concussion may include:

  • Listlessness, tiring easily
  • Irritability, crankiness 
  • Change in eating or sleeping patterns 
  • Lack of interest in favorite toys
  • Loss of balance, unsteady walking

If you suspect that you or your child has a concussion, seek medical attention to determine the severity of the injury.
