Heads after airbags: the concussion nobody saw.

The reader did not lose consciousness. The reader remembers the whole thing: the lurch, the bang of the airbag, the smell, the other driver's face. Two days later the reader is sitting in an office off Chesterfield Parkway unable to get through a spreadsheet without the headache sharpening, and has decided it is stress. This piece is for that reader.

A concussion does not need a knockout

The Centers for Disease Control and Prevention describes 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). Note the second half of that sentence. A hit to the body. The head does not have to strike anything. The neck whip that produces whiplash on the valley floor is the same motion that can produce a concussion one level up.

And most concussions happen without a loss of consciousness. Readers wait for a dramatic marker, a blackout or a visible wound, and when it does not come they file the fog under a bad week. The fog is the marker.

What the signs look like in West County

CDC lists the signs and symptoms plainly: headache or a feeling of pressure, nausea, balance problems or dizziness, double or blurry vision, sensitivity to light or noise, feeling sluggish, hazy, or foggy, confusion or trouble concentrating and remembering, and changes in sleep, mood, or behavior, and notes that some may not show up for hours or days (CDC, signs and symptoms).

Here is how those read when the desk hears them from readers. Cannot look at the monitor for long. Snapped at a kid over nothing. Went to bed at eight and still woke up tired. Missed a turn on a road driven every day. Had to reread the same paragraph three times. Lights in the grocery store were too much. None of those sound like a brain injury to the person living them. All of them are on the list.

The bright line, before anything else

Some head symptoms are not a clinic conversation. 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. CDC's own danger signs include one pupil larger than the other, drowsiness or inability to wake up, a headache that gets worse and does not go away, repeated vomiting, slurred speech, seizures, and increasing confusion or agitation. Those go to the emergency department, now, and the desk will not soften that line for anyone.

What the clinic's head lane actually is

Missouri Injury Clinic publishes TBI and concussion rehabilitative therapy after acute injury as one of its three lanes, and on its own site it names the tools rather than gesturing at them. The desk lists them exactly as published, because the point of a local journal is to say what is there and not what sounds good:

• Vagus nerve stimulation, described by the clinic as gentle microcurrent at the tragus of the ear.
• Neurofeedback.
• Alpha Stim.
• Sensory motor integration.
• Exercise with oxygen.
• Oculomotor rehabilitation, meaning the eye-movement work that a screen-intolerant reader will recognize the need for.
• Cognitive rehabilitation, described by the clinic as computerized brain-exercise software.

What this desk can say about those tools is only what the clinic says: that they are the toolset of its TBI lane. We do not publish outcomes, timelines, or statistics, because the clinic does not and we will not invent them. What the desk can say from general knowledge is that a concussion evaluated early and managed on a plan is a different experience from one squinted through for a month, and that the first exam is the hinge.

The neck and the head are one story

A reader with a concussion after a rear-end on 64 almost always has a neck injury too, because the mechanism is shared. The first visit in the auto-injury lane, diagnosis and a treatment plan after a crash, covers both: the history, the physical exam, the findings written down and dated, and a plan. If the findings call for imaging or a different specialty, the right answer is a referral, and a clinic that sends you on is the system working. Read from the valley to the exam table for the shape of the visit.

Why the date matters for a head

For a neck, the dated record ties findings to the collision. For a head, it does something more useful: it captures a baseline. How you were sleeping, what you could tolerate, how you scored on whatever the clinician measured, on a known date. A change two weeks later is then a change from something measured. The record is a care document first, and for a concussion it is the care document that makes every later decision honest.

If a claim is ever part of your story, the dated record from the first exam is what everyone will ask for. That is true for heads exactly as it is for necks, and it is one more reason not to wait for a knockout that is not coming.
