Key takeaways
- A concussion is a mild traumatic brain injury and does not require losing consciousness or striking your head on something.
- After a rear-end hit, fog, light and noise sensitivity, slowed thinking, and word-finding trouble are worth naming out loud.
- Worsening head symptoms, repeated vomiting, or growing confusion are an emergency room trip right now.
- Missouri Injury Clinic publishes TBI and concussion rehab after acute injury as one of its three lanes.
- Say the word head when you call so the exam includes it.
You did not black out. You did not hit the windshield. So it cannot be a concussion, and the fog you have been pushing through at work since the crash must be stress, or bad sleep, or the neck. That chain of reasoning is extremely common and the first link is wrong. The head does not need to hit anything to be injured when the neck is whipped. It only needs to move fast and stop fast.
What a concussion actually is
The CDC defines a concussion as a type of traumatic brain injury caused by a bump, blow, or jolt to the head, or by a hit to the body that causes the head and brain to move rapidly back and forth (CDC HEADS UP). Read the second half of that sentence again. A hit to the body. A rear-end collision is exactly that: the body is shoved by the seat, the head whips, and the brain moves inside the skull. The CDC also notes that most concussions occur without loss of consciousness.
This is why whiplash and concussion travel together more than people expect. The same motion that strains the neck can rattle the head. The symptoms overlap, too, which makes them easy to blame entirely on the neck: headache, dizziness, trouble concentrating, feeling off.
The symptoms people talk themselves out of
Fog. The word everyone uses. You are present but half a second behind. Reading a paragraph twice. Losing the thread of a meeting. Reaching for an ordinary word and finding a gap where it should be. Light from a screen or a bright store feeling like too much. Noise in a restaurant being unbearable in a way it never was. Feeling emotional or irritable for no reason you can name. Sleeping much more, or much less, than usual.
None of those feel like an injury. They feel like a bad week. That is exactly why they go unreported, and why a clinician needs to hear them from you rather than guess. When you call to book the exam, say: it was a car crash, here is the date, my neck hurts, and I have felt foggy since. The word head changes what the exam includes.
Chest pain, a sudden severe headache, weakness or numbness on one side, trouble speaking, a loss of bowel or bladder control, or a head injury with vomiting or worsening confusion is an emergency room trip right now, not a call to a clinic. A head injury with vomiting, worsening confusion, a severe headache that keeps building, or one pupil larger than the other is the emergency room tonight, before any clinic.
Who treats it once you are stable
If an emergency room has seen you and sent you home, or if the symptoms are steady rather than worsening, the next stop is a clinician who does concussion rehab. Missouri Injury Clinic publishes TBI and concussion rehabilitative therapy after acute injury as one of its three lanes, alongside auto injuries and sports injuries. On its TBI rehab page it names the tools it uses: vagus nerve stimulation delivered as gentle microcurrent at the tragus, neurofeedback, Alpha Stim, sensory motor integration, exercise with oxygen, oculomotor rehabilitation, and computerized cognitive rehabilitation software.
This desk does not describe how any of those work in a given case, because that is a clinical conversation and not an editorial one. What we can say is that the first visit is the same deliverable as every auto-injury visit: an exam, written findings, and a plan. If the head is involved, the exam covers the head. If the findings point somewhere the clinic is not the right room for, a clinician who cannot say so is not one worth seeing, and the honest ones say so.
Why the record matters more with a concussion
Neck stiffness is easy to see. Fog is not. A concussion that is never named in the first week is a concussion that, on paper, never happened, and on paper is where the next clinician starts. The record is a care document first. With a head injury it is also the only way anyone can tell two weeks later whether the fog is lifting, holding, or getting worse, because memory is the instrument being affected.
If a claim is ever part of your story, the dated record from the first exam is what everyone will ask for. That is a fact about how records work, not advice about claims, which this desk does not give. You do not need to have decided anything about a claim before you get examined. You need the head symptoms written down while they are fresh.
Concussion rehab is a published lane
Say the word head when you call.
Steady fog, light sensitivity, or word-finding trouble after a crash is a clinic exam this week. Worsening head symptoms are an emergency room tonight. When you book, tell them the neck hurts and the head has felt off since.
Missouri Injury Clinic, Joseph L. Hollingsworth, DC. Hazelwood, Tesson Ferry, and O'Fallon. Every room is closed 12 to 2.
What to do between now and the exam
Rest the brain the way you would rest an ankle. Less screen, less noise, no alcohol, no sport. Do not drive if you feel slow, and be honest with yourself about whether you do. Write down what you notice each day in two lines, because by the exam you will have forgotten how Tuesday felt. Bring any ER paperwork. Bring someone if you can. A second set of ears in an exam room is worth a great deal when the first set is foggy.
