How to recognize concussion?

After a car crash, fall, or any impact, your brain needs to be your top priority. A knock to the head or a whiplash can be trickier than it looks. A concussion is an invisible brain injury, and its signs can be subtle. They can also show up hours or even days later.

RED FLAGS: Go to the ER Immediately

If you or someone else has any of these signs after an injury, this is an emergency. Call 911 or go to the nearest emergency room.

  • Repeated Vomiting

  • A Headache That Gets Worse and doesn't stop

  • Extreme Confusion or slurred speech

  • Seizures (shaking or convulsions)

  • Loss of Consciousness (passing out) that lasts longer than 30 seconds

  • One Pupil (the black dot in the eye) larger than the other

  • Weakness, Numbness, or poor coordination

  • Extreme Drowsiness or you can't wake them up

Common Signs of a Concussion

Even if you don't have the "Red Flag" symptoms, you can still have a concussion. Look for these signs:

Physical Signs:

  • Any headache or a feeling of "pressure" in the head

  • Nausea (feeling sick)

  • Dizziness or balance problems

  • Blurred vision or "seeing stars"

  • Being sensitive to light or noise

  • Feeling tired or having no energy

Thinking & Memory Signs:

  • Feeling "foggy," "slowed down," or "out of it"

  • Trouble concentrating or remembering new information

  • Being slow to answer questions

  • Forgetting what happened right before or after the injury

Emotional & Mood Signs:

  • Feeling irritable, anxious, or sad for no clear reason

  • Just not "feeling right" or acting like your usual self

Two Rules to Remember:

  1. You DON'T have to pass out to have a concussion. This is a myth.

  2. When in doubt, get checked out. See a medical professional. A proper diagnosis is the first step to healing and is critical for documenting your injuries for any future claims.
