You Are Not Imagining It: Naming What Standard Care Has Missed
For the family member carrying the worry alone.
You have watched it happen slowly. The person you love is still here, still in the same house, still answering when you call their name, and yet something has quietly gone missing. The humor is flatter. The mornings are heavier. The old spark that used to fill a room now flickers, and you find yourself carrying a worry you cannot quite put into words. You are not imagining it. And you are not alone in noticing something that the doctors, so far, have not been able to name.
When the change traces back to a hit no one connected to it
Sometimes the story starts years or even decades earlier. A car accident. A hard fall off a ladder. A fight. A blast overseas. A game where they got their bell rung and shook it off and went right back in. At the time it seemed like nothing. They walked it off. Life went on. But the brain keeps a longer memory than the calendar does, and a hit like that can echo forward in ways that are easy to miss and even easier to blame on stress, age, or a difficult season.
Here is something worth sitting with. People who once took a bell-ringing hit are more than three times as likely to live with depression, and that elevated risk does not fade quickly. It can persist for years (Beaton et al., 2020, Frontiers in Neurology). This is a large part of why a good family guide concussion depression conversation begins not with the sadness itself, but with the history behind it. The two can be connected even when no one ever drew the line.
Why the usual treatments may not be reaching it
If your family member has tried antidepressant after antidepressant with little to show for it, that experience is not a personal failure, and it is not proof that they are not trying hard enough. It may be a clue. Depression that follows an old head impact can behave differently than the kind those medications were built for.
Most common antidepressants work on serotonin. But the low mood that can follow a hit may run partly on a different system in the brain, one that involves a messenger called glutamate. When the underlying machinery is different, the standard key may simply not fit the lock. In fact, a pooled analysis of antidepressants given after a head impact found no significant difference from placebo (Foreman et al., 2019, J Head Trauma Rehabil). That does not mean nothing can help. It means the right question may not have been asked yet.
The other quiet signs that often travel together
When you are the one keeping watch, it helps to know the whole picture, because low mood rarely arrives by itself after an old injury. You may recognize more than one of these:
- Sleep that never feels restful, or a schedule that has quietly fallen apart. Sleep problems affect somewhere between roughly 30 and 70 percent of people with a head-injury history.
- Fatigue, low drive, weight changes, or a fog that antidepressants do not touch. Up to about one in six people develop a hormone deficiency after a hit (pooled prevalence near 16.8 percent), which can quietly mimic or deepen depression.
- Irritability, a shorter fuse, or a personality that seems dialed down from who they used to be.
- A sense, sometimes years on, that they simply never got back to their old self. That instinct is well founded. In long-term follow-up, roughly half of people who took a bell-ringing hit were not back to baseline years later (TRACK-TBI, 5-year outcomes).
None of these prove any single diagnosis on their own. But together, in someone with an old head injury, they form a pattern that deserves a closer and more curious look than a fifteen-minute medication refill can offer.
What a different kind of look can offer
This is where having neurology on staff changes the conversation. A head-injury history is not a diagnosis and it is not, by itself, a reason to reach for any particular treatment. It is a risk factor, one piece of a fuller story. But it is a piece that standard care often overlooks entirely, and it can be the very reason the usual approach has fallen short. A clinician who is looking specifically for the fingerprints of an old hit is asking a different question than a clinician who is not.
At Brain Recovery Centers, a locally owned clinic in St. Peters, Missouri serving St. Charles County, St. Louis County, and the greater St. Louis metro, that diagnostic lens is the starting point. Depression is measured with a simple standardized score, the PHQ-9, at every visit, so change is tracked honestly rather than guessed at. For treatment-resistant depression, meaning depression that has not responded to standard medications, there are options that work on that other system, the glutamate pathway. Ketamine and esketamine act there, with effects that can be measurable in hours and a neuroplasticity window of roughly 24 to 72 hours (Zanos and Gould, 2018, Molecular Psychiatry). Spravato, the esketamine option, is FDA-approved for treatment-resistant depression. It is not approved for, and is not a treatment for, a concussion or any head injury itself. That distinction matters, and an honest clinic will hold it clearly.
You are not looking for a miracle. You are looking for someone who will finally ask why the standard path did not work, and who has the tools to look in a different place.
A word for the person carrying this alone
If the weight has ever felt frightening, please know that these worries can be talked through, not just endured. History of a bell-ringing hit is associated with elevated odds of death by suicide (Erlangsen et al., 2018, JAMA), and if you are ever afraid for your family member, or for yourself, you can call or text 988 at any hour to reach the Suicide and Crisis Lifeline. Reaching out is not an overreaction. It is what people who love each other do.
You have spent a long time being the one who notices. You saw the change when it was still small, you connected it to a hit that everyone else forgot about, and you refused to accept that this was simply how things were now. That instinct has real value. A proper evaluation from a clinic that has neurology on staff can take that instinct seriously, look at the old history alongside the current picture, and help you understand what has actually been happening. Whatever comes next, naming it clearly is the first honest step, and you do not have to take it by yourself.
The connection between an old hit and today's depression is exactly what a clinic with neurology on staff is built to look at.
Spravato® (esketamine) is FDA-approved for treatment-resistant depression and for depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior. It is not FDA-approved for concussion, traumatic brain injury, or post-concussion syndrome. Use in patients with a concussion history is based on clinical judgment regarding the depression component. Off-label ketamine (IV, IM, oral) is not FDA-approved for any psychiatric indication. This page is educational and not medical advice. Individual results vary.
