The intake form wanted to know how long this had been going on, and you answered six months, because six months ago the flatness got heavy enough to deserve a word. The form never asked about the thing that happened eight months ago. A driver came through a light and your temple met the window frame. Or a cabinet door caught you over the eyebrow, the room went white for half a second, and then you finished cooking dinner.
So the chart reads depression, onset six months, and every decision follows from that line. The plan is not sloppy. It rests on a history with a hole in it, and what sits in that hole may be the reason the plan is going nowhere.
How a head injury falls out of the account
Three things make it easy to misplace.
You never filed it as an injury. Nobody knocked you out. Either you skipped the emergency room, or you went, got a clean scan, and were sent home to rest a few days. A normal CT is genuinely good news, because it rules out a bleed. It forecasts almost nothing about how the next eight weeks will feel.
Then there is the clock. Flat mood, a temper with no fuse left on it, an empty half hour in the middle of the afternoon: those tend to arrive weeks or months later rather than the following morning. By then you have other candidates ready. The job soured. The relationship soured. It is February. Any of that can be accurate and still leave most of the story out.
And the symptom lists sit almost on top of each other. Losing a thought midway through it, thinking through syrup, sleep that breaks apart, flinching at light and noise, no appetite for food you used to want. A questionnaire built to score depression will score all of that as depression. That is not an error. It is an unfinished job.
What the history actually changes
Writing the injury into the record does not select a treatment, and a clinic that stretches your accident into an argument for a particular purchase has gone well past the evidence. The narrower version is the useful one: clinical literature treats prior head trauma as a risk marker for depression that standard prescribing does not move. It is grounds for taking the whole picture more seriously. It does not make ketamine, or anything else, the indicated answer.
What it does change is the texture of the conversation. It accounts for complaints antidepressants were never pointed at: words that stall on the way out, headaches that track screen hours, a haze that thickens in a loud grocery aisle. It opens separate questions that deserve their own appointments, about eye tracking, balance, hearing, and the architecture of your sleep. And it reframes the cost of a side effect, because blunted focus is a different kind of burden for a person whose focus has been borrowed against for months.
It also shapes what a reasonable next move looks like when the prescription pad stops helping. Two honest trials that ended in nearly nothing put you in very ordinary company, and the large sequential trial known as STAR*D found remission becoming less likely at every step after the first (Am J Psychiatry 2006, Rush and colleagues).
The options that sit past the medication list
For depression that stays put after two adequately dosed, adequately long medication trials, two treatments hold federal approval. The first is esketamine, sold as Spravato, sprayed into the nose at a site licensed to dispense it, where someone watches you for a stretch afterward while you keep taking a daily antidepressant. The second, transcranial magnetic stimulation, directs magnetic pulses at a mapped point on the skull over a series of short visits. Neither one involves anesthesia.
Read the wording of that approval closely, because the line matters in your case more than most. Neither option is approved for a concussion, for brain injury caused by impact, or for anything that happens to the brain in a collision. The approval covers depression that medication has not moved. A clinic that smudges that distinction during a consult has told you something about itself.
Ketamine infusions are also used for depression, off label, meaning the approval on the bottle is for something else and the prescribing rests on clinical judgment. Ask about that in those words.
If the question is how to raise the accident at your next visit, Brain Recovery Centers keeps its notes for patients after a crash, which show the sort of questions a history like yours ought to trigger during intake.
How to raise it so it sticks
Build a timeline before you go, one sheet, two columns. Dates on the left. On the right, what happened and what changed. The day of the impact. Whether you went out cold, greyed out briefly, or only felt stunned. Whether anyone examined you that day. Then the week the headaches started, the week sleep came apart, the week you quit answering messages. Hand the sheet over instead of narrating it, and ask that it go into the chart as written.
Then put two questions in the air. Does this injury history change how you are thinking about my case. And if the next medication does nothing either, what is step three. Those two move an appointment further than any description of how tired you are.
Geography is not your problem. If you are anywhere around Wentzville, St. Charles, Lake Saint Louis, Wildwood, or the rest of St. Louis County, clinics built around treatment-resistant depression are within reach. The harder part is getting the injury onto the page, and you can start that at the next visit.
If the bottom drops out before that visit, do not sit alone with it. 988 answers every hour of the day, by phone or by text, and any hospital with an emergency department can take you in tonight.
