MeRT Therapy Explained: How It Differs From Standard TMS

Everything you need to know about MeRT Therapy Explained: How It Differs From Standard TMS — how it works, what it costs, and how to find a provider who actually knows what they're doing.

MeRT treatment is repetitive TMS with an extra step up front. Before stimulation, a clinic records your brain’s electrical activity with EEG, and Wave Neuroscience’s software uses that recording to pick stimulation settings for you, rather than using one standard protocol for everyone. In June 2026 Wave announced that the FDA had cleared its MeRT system for PTSD. That is the only indication we can verify. Everything else MeRT clinics offer, including treatment for depression-related symptoms and for autism, sits outside that clearance. Here is how it works, what’s known, and what to ask.

Key takeaways

• MeRT is a branded, EEG-guided way of setting up rTMS. The magnetic pulses are the same kind used in standard TMS.
• Wave Neuroscience announced an FDA clearance for PTSD on June 11, 2026. We haven’t been able to review the FDA database entry ourselves, so confirm the exact wording with any provider.
• The PTSD trial results had not been peer-reviewed or fully published in the coverage we found. Wave described a double-blind, randomized, multisite study but didn’t release sample size, comparator or side-effect rates.
• There is no evidence we could find that MeRT beats standard TMS for depression.
• For autism, the evidence is limited and low quality, and major experts and advocacy groups say it is not established. Be cautious.

What MeRT actually is

MeRT is usually spelled out as Magnetic e-Resonance Therapy. UTHealth Houston’s psychiatry department calls it Magnetic EEG/ECG-Guided Resonance Therapy and describes it as built on conventional rTMS, with an assessment using quantitative EEG, ECG and computer-analyzed brain oscillations. Stimulation frequency and other settings are then chosen for each patient. Wave’s own release describes it as a platform that combines AI-augmented EEG analysis with individualized neuromodulation protocols.

The idea rests on brain rhythms. In a standard depression course, the clinic usually sets the coil position and then the intensity (your motor threshold), and everyone receives the same pattern of pulses. MeRT adds a recording step to tailor frequency to your own EEG. If you want the basics first, see our explainers on TMS versus rTMS terminology and AI-guided TMS targeting.

MeRT vs standard TMS

FDA status, stated carefully

Here is what we can say as of October 2026.

• Wave Neuroscience announced on June 11, 2026 that the FDA cleared the MeRT system for PTSD, calling it the first FDA-cleared indication for the MeRT platform. Patient Care Online and other trade outlets reported it. The MeRT system had received FDA Breakthrough Device designation in 2024.
• Reporting did not state whether the pathway was 510(k) or De Novo.
• “Cleared” means the device met regulatory requirements for its intended use. As UTHealth’s article puts it, clearance isn’t the same as proof of better clinical effectiveness, and whether MeRT is superior to conventional TMS will take more comparative studies.
• “FDA-cleared” does not extend to every condition a clinic lists on its website.

If a clinic tells you MeRT is “FDA-approved” or cleared for your condition, ask for the indication in writing.

What the evidence shows

PTSD

The clearance is based on a double-blind, randomized, controlled, multisite trial run with the Texas A&M Health Institute of Biosciences and Technology, according to Wave’s announcement. Patient Care Online noted that the announcement didn’t disclose sample size, comparator, treatment duration, effect size or adverse event rates, and that the clinical significance of the personalization will depend on peer-reviewed reporting. Until the paper is out, we can’t tell you how big the benefit is.

Earlier work is smaller and uncontrolled:

• A 2015 open-label report of magnetic stimulation set from each person’s alpha-band EEG frequencies, in 21 veterans with PTSD (16 completed two weeks of treatment), found PCL-M scores fell from an average of 54.9 to 31.8. Open-label means no placebo group.
• A 2024 retrospective chart review of active-duty special operations service members receiving an average of 30 sessions of individualized alpha-frequency rTMS reported a 37% average drop on the PTSD checklist. There was no control group, and chart reviews can’t separate treatment effects from other changes.

For standard approaches to PTSD, see our guide to TMS for PTSD and the PTSD treatment page.

Depression

Standard TMS has a large body of evidence for depression, and we covered what to expect in TMS success rates. We did not find a randomized trial showing that MeRT’s EEG-based individualization improves depression outcomes compared with standard TMS.

It’s worth knowing that personalization doesn’t automatically win. In a five-center randomized trial of 255 people with treatment-resistant depression, fMRI connectivity-guided theta burst stimulation was no better than standard rTMS over 26 weeks. That trial used a different kind of personalization from MeRT’s, so it doesn’t say anything direct about MeRT. It does show that individualized targeting needs head-to-head testing.

Autism

This is the area that needs the most care. MeRT clinics have marketed treatment for children with autism, but:

• The FDA clearance announced is for PTSD only. Use for autism is off-label.
• Reporting by the Los Angeles Times, republished by MindSite News, found that nine psychiatrists and neuroscientists said no large studies show MeRT works better than placebo for autism, and that Wave had not conducted studies to verify it. Families reported mixed results, from improvement to no change, and a few reported behavioral regressions. The article reported out-of-pocket costs of about $9,000 and no insurance coverage. Those figures are from 2024 reporting, so ask for current prices.
• The American Society for Autism Treatment responded to the Times in 2025 that there is no conclusive evidence MeRT works for autism.
• A 2026 meta-analysis of 53 randomized trials of rTMS in autism (not MeRT specifically) found possible symptom improvements but rated the certainty of evidence low to very low, with 85% of trials open-label, and concluded rTMS can’t yet be recommended as routine treatment for autism.

If you’re weighing this for your child, talk with their developmental pediatrician or psychiatrist first, and consider whether a registered clinical trial would be a better route. Our overview of TMS for autism spectrum disorder and the autism treatment page cover what’s known.

Questions to ask a MeRT provider

1. What is the exact FDA-cleared indication for the device and system you’ll use on me or my child?
2. Which condition are you treating, and is that condition covered by the clearance?
3. Which outcome measures will you track, and how often?
4. What happens if there’s no improvement by a set point?
5. What is the full price, including the EEG assessment, and what’s billed to insurance?
6. How do you screen for seizure risk and other contraindications? See who should not get TMS.
7. Can I see published data for the protocol you’ll use?

If you’re comparing options for depression

If your main goal is relief from depression, standard FDA-cleared TMS has the longest track record, and our post on TMS for treatment-resistant depression explains who qualifies. It’s also worth reading what to do when TMS isn’t working and can TMS make anxiety worse before starting any course.

Find a TMS clinic near you and ask each one what protocols they use. Or take the two-minute candidate quiz to see whether TMS is worth discussing with your doctor.

Frequently asked questions

What does MeRT stand for?

Magnetic e-Resonance Therapy. Some institutions, including UTHealth Houston, describe it as Magnetic EEG/ECG-Guided Resonance Therapy. It’s Wave Neuroscience’s branded approach to individualized rTMS.

Is MeRT FDA-cleared?

Wave Neuroscience announced in June 2026 that the FDA cleared the MeRT system for PTSD. That is the only indication we can verify. Ask any clinic for the specific indication and device they use, because a PTSD clearance does not cover every other condition.

Is MeRT better than regular TMS?

We don’t know yet. We found no head-to-head randomized trial comparing MeRT with standard TMS, and the PTSD trial results hadn’t been fully published in the sources we reviewed. Personalized approaches are promising in theory but need direct comparison.

Does MeRT work for autism?

The evidence is limited. Experts quoted in Los Angeles Times reporting said there are no large studies showing it beats placebo, and the FDA clearance announced is for PTSD, not autism. A 2026 meta-analysis of rTMS in autism rated the evidence low to very low certainty. Talk with your child’s doctor before committing money and time.

Is MeRT covered by insurance?

We couldn’t verify coverage patterns. Standard TMS for depression is often covered after prior authorization, but MeRT’s EEG assessment and non-cleared uses may not be. Ask the clinic what they bill and get your plan’s answer in writing.

Is MeRT safe?

It uses magnetic pulses like standard TMS, and the 2024 chart review reported side effects matching those commonly reported with rTMS. Seizure screening still applies. Wave’s trial did not publish adverse event rates in the coverage we found.
