A private tool to help you understand a possible brain injury after a car crash — spot the danger signs that mean you need care now, screen your symptoms, and bring a clear summary to your doctor or legal counsel.
Please read first. This is not a medical diagnosis and not a medical device. It turns what you enter into a research-based summary that helps you and your doctor — it does not replace a real medical evaluation.
A low result is not an all-clear. Some brain injuries don't show up right away, and symptoms can appear or get worse in the days after a crash. When in doubt, see a doctor.
Not for emergencies. If you or someone with you has danger signs of a serious head injury, call 911. In crisis, call or text 988 (Suicide & Crisis Lifeline), 24/7.

Spot the danger signs. Screen your symptoms. Bring a clear summary to your doctor or legal counsel.
Check any that are happening now. These can mean a serious, life-threatening head injury. If you check any, call 911 or go to the ER right away.
Tell us what happened. This helps show how the crash forces could have affected your brain. Your best guess is fine.
These details help grade how serious the injury may be (standard ACRM / CDC criteria). Use what you know; choose “unknown” if you're not sure.
Rate how much each has bothered you in the past few days — 0 = not at all, 4 = very severe. These are the symptoms doctors screen for after a concussion.
Keeping track of your care helps your recovery — and your summary. Add what you've done so far.
How this was determined
The severity grade uses standard ACRM/CDC criteria. The injury-mechanism and symptom indicators are research-based guides — not a diagnosis. Use your results to decide whether to see a doctor — and, if you're considering a claim, what to share with an attorney.
Make a one-page summary of your crash, symptoms, and care to bring to your doctor or legal counsel, or keep for your records.
The tool applies published criteria and research; it is not itself a diagnostic instrument.
