Concussions can be tricky to diagnose. Though you may have a visible cut or bruise on your head, you can’t actually see a concussion. Signs may not appear for days or weeks after the injury. Some symptoms last for just seconds; others may linger.
Concussions are fairly common. Some estimates say a mild brain trauma is sustained every 21 seconds in the U.S. But it’s important to recognize the signs of a concussion so you can take the proper steps to treat the injury.There are some common physical, mental, and emotional symptoms a person may display following a concussion. Any of these could be a sign of traumatic brain injury:

  • confusion or feeling dazed
  • clumsiness
  • slurred speech
  • nausea or vomiting
  • headache
  • balance problems or dizziness
  • blurred vision
  • sensitivity to light
  • sensitivity to noise
  • sluggishness
  • ringing in ears
  • behavior or personality changes
  • concentration difficulties
  • memory loss
