In health care, skepticism is a healthy reflex. When someone says a new treatment will change your life, the first question should be: according to whom? This explainer is for St. Peters readers who doubt ketamine therapy and wonder whether the "drug-free" alternative they keep hearing about holds up to the same scrutiny.
We will pull it apart the way a skeptic would: what it is, what its regulatory standing really is, what it costs in time and money, and what it cannot promise.
Why we are writing about this
Over the summer we funded a poll of 443 adults in Missouri and nine surrounding Midwest states, and two findings stood out side by side. When the phrase ketamine therapy came up, 21 percent of respondents described their gut response as skeptical and 9 percent as negative. Meanwhile 64 percent of respondents wanted a drug-free option available, yet just 25 percent knew what TMS, a depression treatment without medication, actually is.
The survey has no breakdown for skeptics, which leaves their own TMS answers out of view. We can say that many people want a drug-free route and few know the name of the main one. All of it is final.
What TMS is, minus the marketing
The initials mean transcranial magnetic stimulation. A treatment coil sits against your scalp and produces rapidly changing magnetic fields, which induce small electrical currents in the tissue below. The usual target is a region toward the front of the brain that helps regulate mood and tends to be underactive in depression.
That is the entire mechanism. Nothing enters your body, no anesthesia is involved, you stay awake in a chair, and you can generally drive afterward.
The evidence question, answered carefully
A skeptic wants to know which review a treatment passed. For TMS the answer is FDA clearance to treat adult major depression when antidepressants have not produced improvement. Clearance is the pathway the FDA uses for many medical devices, TMS systems included; it is a different process from drug approval, and knowing which word applies is useful.
That distinction resonates. Our respondents agreed, with 59 percent treating FDA approval as a make-or-break or heavy consideration for new treatment. If regulatory status matters to you, have any clinic name its device and the use it is cleared for, and expect a straight answer.
Clearance does not tell you whether TMS will work for you. Like every depression treatment, it helps some people a lot, some partly, and some not at all, and a clinic promising results is overselling.
What it costs you
Time. The biggest ask: sessions on most weekdays for several weeks, with a longer first visit to map the spot and strength. Some clinics offer accelerated schedules; ask whether they apply to you.
Comfort. Expect tapping on the scalp and a loud click. Scalp soreness and headache lead the side effects; seizures are rare, and clinics screen for risks such as a seizure history or metal near the head.
Money. Plenty of insurers pay for TMS in depression once prior authorization is granted, usually on proof that antidepressants fell short. Without coverage a full course can be expensive, so get the total out-of-pocket estimate in writing.
Coverage was the concern respondents raised most. For 85 percent of respondents, coverage made the shortlist of their two chief demands of a provider, and in a separate question 65 percent said coverage would be deciding or a big factor in trying a treatment at all.
What TMS is not
- Not ECT. Electroconvulsive therapy uses general anesthesia and induces a seizure; TMS does neither.
- Not a cure. Some people need maintenance sessions or more treatment later.
- Not a reason to quit medication on your own. Many people keep taking antidepressants during TMS, and changes belong with your prescriber.
- Not for everyone. Some medical histories rule it out, and only a clinician can decide that.
How it compares with what you doubt
If your doubt centers on ketamine, know that the ketamine landscape has layers. Esketamine, the active drug in Spravato, comes as a nasal spray approved for treatment-resistant depression, administered at a certified site with supervision and a monitoring period, and Brain Recovery Centers has a page on the Spravato treatment experience if you want specifics. IV ketamine infusions for depression use an anesthetic off label, and home ketamine products form a looser category.
TMS is device-based with no medication at all. Each tends to surface as an option once ordinary antidepressants disappoint; they are different tools, and a clinician can help you decide which, if either, fits.
A skeptic's checklist for any TMS clinic
- Which device do you use, and what exactly is it cleared for?
- Who evaluates me beforehand, and is a psychiatrist involved?
- How and how often do you measure progress?
- What happens if I am not improving partway through?
- Will you handle prior authorization, and what do I owe if it is denied?
- Do you have appointment times that fit a commute?
That last one matters in St. Peters, where many people drive I-70 or Highway 364 daily, and a near-daily treatment only works if the clinic is reachable when you are free. Nearness was a top two concern for 43 percent of our respondents.
Where to start
Start with a clinician you already trust. Asked whose advice would most move them to try a new treatment, 74 percent of respondents pointed to the physician they already see. You can put it plainly: "I'm skeptical of ketamine. Would you consider TMS for me, and why or why not?"
If you are struggling and having thoughts of suicide, please call or text 988. Doubting a treatment is fine; going without support is not something you have to do.
Methodology
Pollfish panelists supplied the answers, and the publisher both ordered and bankrolled the project. Responses closed June 23, 2026, at 443, every one from a consenting Midwesterner aged 18 to 64 in a ten-state sample. Results are top-line only and final.
