Research & Evidence

The research behind MeRT.

MeRT® builds on a growing body of third-party, peer-reviewed research into EEG-guided rTMS across several conditions. Here's a summary of what that research covers.

How to read this page

We distinguish peer-reviewed journal studies from news coverage, professional-organization commentary, and preliminary (poster-only or unpublished) findings below. Media coverage and expert commentary can be useful context, but it isn't the same standard of evidence as a published, peer-reviewed study — we label each accordingly. Results in any cited study may not predict results for any individual patient, and treatment protocols in cited studies are not always identical to the MeRT protocol used at Brain Treatment Center Michigan.

TMS and depression research

rTMS devices are FDA-cleared for treatment-resistant major depressive disorder, and published research has examined TMS as a treatment option for moderate to severe depression, including for patients who haven't responded adequately to medication.

One widely-cited study, Stanford Neuromodulation Therapy (SNT): A Double-Blind Randomized Controlled Trial (Cole et al., American Journal of Psychiatry, 2022), reported remission in a majority of participants with severe, treatment-resistant depression using an accelerated, high-dose protocol delivered over five days.

Caveat: the SNT/SAINT protocol studied is a different, proprietary accelerated protocol developed at Stanford — it is not the same treatment as the EEG-guided MeRT protocol delivered at Brain Treatment Center Michigan. It's relevant as evidence that intensive TMS approaches can produce strong results, but should not be read as a study of MeRT itself.

TMS and PTSD research

Published research, including small studies and pilot trials involving military populations, has examined rTMS for PTSD and associated depression symptoms. Some of the most visible PTSD/TMS coverage — including a widely-shared 2019 Defense One feature on active-duty service members — is journalism, not a peer-reviewed study, and several supporting trials in this area are described in conference posters rather than published, peer-reviewed papers.

Caveat: much of the public PTSD/TMS coverage referenced above is journalism or conference material rather than published, peer-reviewed research, and study populations (military vs. civilian) vary — those distinctions matter when weighing the evidence.

TMS and autism spectrum research

A growing body of research has examined rTMS in autism spectrum populations, including systematic reviews and meta-analyses looking at behavioral and attention-related outcomes. Most recently, Noninvasive reduction of neural rigidity alters autistic behaviors in humans (Watanabe & Yamasue, Nature Neuroscience, June 2025) found that targeted TMS reduced measures of "neural rigidity" and associated autistic behaviors. See our full research summary on rTMS for autism for additional citations and caveats.

Caveat: the 2025 Nature Neuroscience study was conducted in autistic adults, not children — it should not be read as direct evidence for pediatric outcomes without that distinction.

Other areas of research

Published research has also examined rTMS for symptoms following traumatic brain injury (including mood and cognitive symptoms) and for anxiety disorders. Evidence in these two areas is generally earlier-stage than for depression — it includes case reports, small pilot studies, and reviews calling for larger controlled trials, rather than the larger randomized trials available for depression.

Caveat: because much of the TBI and anxiety literature consists of small or preliminary studies, results from any single study shouldn't be read as broadly generalizable.
