Transcranial magnetic stimulation has been FDA-cleared for depression since 2008, yet misconceptions still keep patients from a treatment that could help them. Here are the ten myths we hear most often — and what the evidence actually says.
Myth 1: “TMS is the same as electroshock therapy”
False. This is the most persistent myth, and the most costly. Electroconvulsive therapy (ECT) induces a controlled seizure under general anesthesia. TMS uses magnetic pulses to stimulate a specific brain region — no anesthesia, no seizure, no memory effects. You sit in a chair, awake, and drive yourself home afterward. See our full TMS vs ECT comparison.
Myth 2: “TMS causes memory loss”
False. Memory side effects belong to ECT, not TMS. Clinical trials have not found a pattern of memory or cognitive harm from TMS, and some studies report improved concentration as depression lifts. We reviewed the data in does TMS cause memory loss?
Myth 3: “It’s experimental”
False. TMS has FDA clearance for major depressive disorder (2008), OCD (2018), smoking cessation (2020), and anxious depression (2021). It is included in major clinical guidelines for treatment-resistant depression, and Medicare and many commercial insurers cover it when their criteria are met.
Myth 4: “Insurance never covers it”
False — with a caveat. Many insurers cover TMS for treatment-resistant depression, typically after a set number of failed medication trials (it varies by insurer; some policies require two). The paperwork is real, and thorough documentation helps. Our insurance appeals guide walks through the process, including what to do after a denial.
Myth 5: “TMS is painful”
Mostly false. The sensation is a firm tapping on the scalp. The first few sessions can be uncomfortable — scalp sensitivity is the most common complaint — but it fades within a week for most patients as they acclimate. Read what TMS actually feels like for first-hand accounts.
Myth 6: “The results don’t last”
False. Durability data are encouraging: in one 12-month follow-up study, about 62% of acute responders still met response criteria a year later (Dunner et al., 2014). Relapse still occurs, and some patients receive additional sessions. Details in how long does TMS last?
Myth 7: “You have to stop your medications”
False. Most patients continue their antidepressants during TMS. The treatments work through different mechanisms and are routinely combined — many clinicians prefer keeping medication stable so progress can be attributed accurately.
Myth 8: “TMS is only for depression”
False. Beyond depression, TMS devices hold FDA clearances for OCD, smoking cessation, anxious depression, and migraine, with active research in chronic pain, PTSD, and more than a dozen other conditions.
Myth 9: “If antidepressants didn’t work, nothing will”
False — and backwards. TMS was specifically studied in patients who failed medications. The landmark trials enrolled people with treatment-resistant depression, and real-world studies have reported response rates of roughly 50–60%, though results vary and TMS does not work for everyone. Medication failure is the entry criterion, not a disqualifier.
Myth 10: “All TMS clinics are the same”
False. Devices, protocols, technician experience, and physician oversight vary meaningfully between providers. Outcomes depend on accurate targeting and consistent delivery. Compare providers in our clinic directory, and learn how to read clinic reviews before you choose.
The bottom line
TMS is an established, FDA-cleared treatment with a generally mild side-effect profile and encouraging durability data. If outdated information has kept you from considering it, start with the basics in What is TMS? — then talk to a provider about whether you’re a candidate.
