Everything you need to know about TMS Isn't Working: What to Do at Week 3, Week 6, and Beyond — how it works, what it costs, and how to find a provider who actually knows what they're doing.
The TMS Patient Buyer's Guide
Everything to know before your first consult — questions to ask, what to expect, and how to compare providers.
Somewhere around session 12, a lot of TMS patients have the same quiet, sinking thought: this isn’t doing anything. If that’s you, this article is for you — not to reassure you that everything is fine, but to lay out honestly when “not yet” is normal, when it’s time to change something, and what the real options are if a full course doesn’t work.
First, the base rates
In treatment-resistant depression, roughly half to 60% of patients respond to a standard TMS course (meaning symptoms drop by at least half), and around a third reach remission. Those are good numbers for a population that has already failed multiple medications — and they also mean a large minority won’t get enough benefit from round one. Non-response is common. It is not a verdict on you, and it doesn’t close the door on feeling better.
It’s also worth knowing that response is often not linear. Many people feel nothing for weeks and then improve steeply in weeks four to six. Sleep changes, and other people noticing you seem different, often show up before you feel different yourself — our week-by-week guide maps that arc in detail.
Week 3 checkpoint: too early to quit, right time to review
By session 15, it’s reasonable to sit down with your provider and review. Bring data, not vibes — your weekly PHQ-9 scores tell a clearer story than memory does (here’s how to track them).
Questions worth asking at this checkpoint:
- Has my motor threshold been rechecked? Thresholds drift. Treating below an accurate threshold means under-dosing. (What motor threshold is and why it matters.)
- Is the targeting method the best available here? Scalp-measurement targeting misses the ideal spot in a meaningful fraction of patients. Ask whether the clinic can review or adjust coil placement.
- Am I on the right protocol? Standard 10 Hz left-side treatment isn’t the only option. Right-sided low-frequency stimulation, bilateral protocols, and theta-burst stimulation are all legitimate mid-course conversations, especially if you’re having tolerability problems.
One more uncomfortable but necessary check: attendance. TMS dosing is cumulative. If you’ve missed several sessions, the course you’ve received is smaller than the course that was prescribed.
Week 6 checkpoint: defining “didn’t work” honestly
A standard course is 30 to 36 sessions. At the end, outcomes sort into three groups, and the next move differs for each:
Partial response (clearly better, not well). This is the most common “unsatisfying” outcome, and it’s also the most actionable. Extension courses — continuing two to three more weeks — convert a meaningful share of partial responders into full responders. Ask directly: “What would an extension look like, and will insurance cover it?”
No response, protocol unchanged throughout. Before concluding TMS failed, it’s fair to ask whether this specific delivery of TMS failed. A switch — different protocol, different coil type (deep TMS vs. figure-8), different targeting — is a genuinely different treatment in a way that a third SSRI after two failed SSRIs is not.
No response despite good execution. If the clinic rechecked thresholds, adjusted targeting, tried a protocol change, and you completed the course — then it’s time to look beyond standard TMS, with no guilt attached.
Beyond a standard course: the real options in 2026
Accelerated / SAINT-style protocols. The Stanford SNT protocol — multiple theta-burst sessions per day with individualized fMRI targeting, completed in about a week — posted striking remission rates in trials and is slowly becoming available at specialized centers. Importantly for you: prior non-response to standard TMS does not exclude you, and some centers see it as exactly the population to treat. Availability and insurance coverage remain the bottlenecks — see where accelerated TMS stands in 2026.
Esketamine (Spravato). Nasal-spray esketamine is FDA-approved for treatment-resistant depression, works through a completely different mechanism than TMS, and has no cross-resistance with it — failing one says nothing about the other. Compare honestly: Spravato vs. TMS.
Medication strategy reset. A TMS non-response is a reasonable trigger for a fresh psychiatric review: MAOIs, lithium augmentation, and pharmacogenomic testing all still have a place, and a psychiatrist who has just watched you not respond to TMS has better information than the one who started your first SSRI years ago.
ECT. It has the highest response rates of any treatment for severe depression — meaningfully higher than TMS — at the cost of anesthesia, more logistics, and cognitive side effects TMS doesn’t have. For severe, high-stakes depression it deserves an honest look rather than a reflexive no. Our TMS vs. ECT comparison lays out the trade.
Second opinion at a different clinic. Equipment, protocols, and clinical attention genuinely vary between clinics. If your course was delivered with minimal monitoring and zero adjustments, a more rigorous center is not a repeat of the same experiment. Our directory lets you compare clinics near you, and this guide covers what separates good clinics from mediocre ones.
What we’d actually do
If a friend finished 36 sessions with nothing to show for it, here’s the order we’d suggest: get your complete treatment record from the clinic (thresholds, protocol, any changes made — you’re entitled to it), book a psychiatric review to re-examine the diagnosis (bipolar spectrum, ADHD, sleep apnea and thyroid problems all masquerade as treatment-resistant depression), and then choose between an accelerated-protocol center and esketamine based on what’s accessible to you.
Not responding to one treatment narrows the map. It doesn’t erase it.
