Concussion symptom tracker Track what the scan does not show you.

Most concussions produce a normal CT scan, because CT looks for bleeding, not for a concussion. The diagnosis, and the claim, rest on the record of symptoms over weeks: when they started, how bad, and what they stopped you doing. Rate each one once a day and bring the printout to every appointment.

Seven days, one rating a day

Notes for the doctor: what set it off, what you could not do, how long it lasted.

Why this matters

An adjuster reads a normal CT as no injury. A neurologist reads three weeks of documented light sensitivity, word-finding trouble, and headaches as a mild traumatic brain injury. The tracker is what turns your experience into a record.

Go to an emergency room now if

A headache that keeps getting worse, repeated vomiting, a seizure, one pupil larger than the other, weakness or numbness, slurred speech, growing confusion, or you cannot be woken. These are the CDC's danger signs after a head injury. Saved on this device only; this tracker does not diagnose anything.
