Injury and Imaging Questions

Can I have a concussion without hitting my head?

Short answer

Yes. Concussion can result from rapid acceleration or deceleration of the head, even without a direct blow.

Deeper explanation

A concussion is a functional brain injury caused by forces transmitted to the brain. In an auto accident, the head can accelerate and decelerate quickly enough to produce concussion symptoms without striking anything.

Common signs include headaches, brain fog, difficulty concentrating, light or noise sensitivity, dizziness, sleep changes, and emotional changes.

Urgent care

When to seek urgent medical care

  • Loss of consciousness, seizure, or repeated vomiting
  • Progressive drowsiness or confusion
  • Focal weakness, numbness, or trouble speaking

If you have any of the above or other emergency symptoms, call 911 or go to the nearest emergency department.

What a proper evaluation should include

  • Concussion history and symptom inventory
  • Neurologic and vestibular/oculomotor screening
  • Referral for advanced testing or imaging when indicated

Documentation considerations

The record should capture the mechanism of injury, timing and progression of symptoms, and any functional limitations at work, at home, or while driving.
