This FDA-cleared approach condenses treatment into a matter of days by delivering multiple sessions per day instead of one. For patients with treatment-resistant depression, anxiety, PTSD, or OCD who need relief sooner rather than later, that's a meaningful difference.
This guide covers how accelerated TMS works, what the research says about its effectiveness, what treatment actually looks like, and how it stacks up against standard TMS and medication.
Key Takeaways
- Accelerated TMS compresses a 6-week course into as little as 5-10 days using multiple daily sessions
- FDA-cleared protocols include BrainsWay's accelerated Deep TMS™, cleared in September 2025
- Clinical trials show comparable remission rates to standard TMS, with faster symptom relief
- TMS Center Centennial pairs accelerated protocols with certified technicians, a Medical Director, and psychiatrists skilled in treatment-resistant depression
What Is Accelerated TMS and How Does It Differ from Standard TMS?
Standard TMS delivers one session a day, five days a week, for four to six weeks. Accelerated TMS delivers several sessions per day, often with rest breaks in between, over just one to two weeks.
The technology behind most accelerated protocols is intermittent theta-burst stimulation (iTBS). Instead of a continuous pulse pattern that takes 20+ minutes per session, iTBS uses short bursts (three pulses at 50 Hz, repeated at 5 Hz) that let a full session finish in about 3 minutes. That's what makes multiple daily sessions realistic in the first place.
BrainsWay received FDA clearance for its accelerated Deep TMS™ protocol in September 2025. It's indicated for major depressive disorder (MDD) in adults who haven't improved enough on antidepressant medication, and it runs on a two-phase structure:
- Acute phase: 5 sessions/day for 6 treatment days, spread across a 14-day period, each session under 10 minutes
- Maintenance phase: 2 sessions once weekly for 4 weeks afterward
TMS Center Centennial offers a similar accelerated option called Swift Deep TMS™, using theta burst stimulation. Each TBS session runs about 3 minutes, with an intensive course of 30 sessions completed over 6 days, and total treatment wrapping up in roughly 2 weeks.
Quick comparison:
| Factor | Standard TMS | Accelerated TMS |
|---|---|---|
| Session length | ~20 minutes | Under 10 minutes (often ~3 min with iTBS) |
| Sessions/day | 1 | 5-10 |
| Total duration | 4-6 weeks | 1-2 weeks (intensive/acute phase) |
| Best fit | Flexible schedule, gradual approach | Urgent need, limited time availability |
Who Is a Candidate for Accelerated TMS?
Accelerated TMS is generally considered for the same conditions as standard TMS: treatment-resistant depression, anxiety, PTSD, and OCD. It's especially appealing for patients dealing with severe symptoms or suicidal ideation who need faster relief.
Standard exclusion factors for magnetic stimulation therapies include:
- Non-removable conductive metal implants near the head
- Cochlear implants, deep-brain stimulators, or vagus-nerve stimulators (active or inactive)
- Certain seizure-related risk factors, evaluated individually by a physician
At TMS Center Centennial, a physician reviews your full medical history before recommending either protocol. A history of psychotherapy is generally required as part of that evaluation - you'll just need to tell us who you saw for therapy and roughly when. Eligibility and the treatment plan are finalized after that clinical evaluation, not before.
How Effective Is Accelerated TMS? (Clinical Outcomes)
The most rigorous data comes from the Stanford Neuromodulation Therapy (SNT) trial, a double-blind randomized study published in the American Journal of Psychiatry. Using 10 iTBS sessions a day for 5 consecutive days, researchers found:
- 85.7% of active-treatment participants achieved response (at least 50% symptom reduction) at some point during follow-up
- 78.6% achieved remission at some point
- Depression scores dropped by 62% immediately after treatment and 70.9% at the one-week mark, compared to roughly 14-20% in the sham group That's a fast, strong result. Context matters, though. A broader 2018 systematic review of accelerated TMS studies covering 366 patients found accelerated protocols produced a 23% reduction in depression severity at four weeks, versus 31% for standard TMS. Accelerated and standard approaches land in a similar range overall, but individual protocols (like SNT) can outperform expectations. In practice, accelerated TMS reaches outcomes comparable to standard TMS on a compressed timeline. For context, medication and therapy benchmarks from the NIMH's STAR*D study show roughly one-third of patients reaching remission after a first antidepressant trial, with similar rates after switching medications or trying cognitive therapy. TMS protocols, accelerated or standard, tend to post higher response rates for patients who've already failed those first-line options.
Anxiety and PTSD Outcomes
Solid randomized data specific to accelerated protocols for anxiety and PTSD alone is still thin. One published case report described a patient with PTSD and depression whose trauma symptom scores dropped substantially after an accelerated combined protocol, but that's a single case, not proof of broad efficacy. If you're being treated for PTSD or anxiety at a clinic, ask directly what evidence supports the specific protocol you're being offered.
Accelerated TMS vs. Standard TMS: Weighing the Pros and Cons
Neither approach is universally better. The right fit depends on your schedule, insurance, how quickly you need relief, and how much long-term research you want behind the protocol.
Pros of accelerated TMS:
- Finishes in days to two weeks instead of six weeks
- Fits better around work travel, caregiving duties, or urgent symptom relief needs
- Similar safety profile to standard TMS, with no evidence of increased long-term risk
Cons of accelerated TMS:
- Treatment days are longer and more intensive, sometimes requiring hours at the clinic
- Insurance coverage can be less consistent than for standard protocols
- Fewer large-scale, long-term studies exist compared to decades of standard TMS research
Pros of standard TMS:
- Shorter daily visits, often under an hour per session
- More consistent insurance coverage under many major plans
- Decades of research and clinical use supporting long-term outcomes
Cons of standard TMS:
- Full course usually means about six weeks of near-daily clinic visits
- Harder to fit around travel, heavy work schedules, or urgent relief needs
If six weeks of daily visits is not realistic, accelerated TMS solves a real logistical problem. If you prefer shorter days and a longer, well-studied course, standard TMS remains a strong option.
What to Expect During Accelerated TMS Treatment
Before your first session, a physician reviews your history and confirms TMS is appropriate.
At TMS Center Centennial, a Certified TMS Technician and the assigned physician then perform coil mapping. They place the treatment cap and deliver small pulses to locate your correct treatment area and motor threshold.
During mapping, you may notice involuntary twitching in your fingers or face. That reflex is normal—patients often describe it as mildly uncomfortable, not alarming.
The Treatment Schedule
Once mapping is complete, accelerated sessions typically follow this pattern:
- Multiple short sessions per day (often 5-10), each lasting a few minutes
- Rest intervals between sessions, ranging from under an hour to about 90 minutes
- Daily treatment over roughly a week, sometimes followed by a maintenance phase
You stay awake and alert throughout. There's no sedation and no recovery downtime, so most patients drive themselves home and return to normal activities right after each session.
Common Side Effects
The most frequently reported issue is temporary scalp discomfort or headache during or shortly after a session. Patients at TMS Center Centennial have described it as mild soreness lasting about 20 minutes, or an "annoying knock" sensation rather than actual pain.
It typically resolves on its own within the first week of treatment and can often be eased with an over-the-counter pain reliever.
Safety, Cost, and Insurance Considerations
TMS carries a low seizure risk. Published safety literature puts the overall risk below 1%, with some large-scale data showing rates closer to 0.08 per 1,000 sessions. Before starting, every patient completes a standard safety screening covering implants, seizure risk factors, and relevant medical history.
Pricing and insurance coverage vary by clinic and protocol. TMS Center Centennial accepts most major insurance plans, including:
- Cigna
- Anthem Blue Cross Blue Shield
- TRICARE
- United Healthcare
- Aetna
- Most Medicare plans
Copays and out-of-pocket costs depend on your plan and deductible, so confirm coverage with the clinic before you schedule. Private-pay options are also available if insurance does not apply.
The same team that handles safety screening can help you navigate benefits questions. TMS Center Centennial combines Deep TMS™ and Swift Deep TMS™ with NeurOptimal® neurofeedback and collaborative counseling, supported by a Medical Director, a board-certified psychiatrist, a licensed marriage and family therapist, and certified TMS coordinators. That setup gives patients clinical support and treatment options beyond stimulation alone when a care plan calls for it.
Frequently Asked Questions
How expensive is accelerated TMS?
Costs vary by clinic, protocol, and insurance plan. TMS Center Centennial performs an individualized benefits analysis and accepts most major insurers, so contact them directly to discuss coverage and payment options.
How quickly can TMS work?
Some patients notice symptom improvement within days of starting an accelerated protocol, with research showing measurable score reductions as early as the first week. Individual timelines vary based on symptom severity and treatment response.
Is accelerated TMS effective?
Yes. Clinical trials, including the Stanford SNT study, show remission rates comparable to standard TMS, often achieved in a fraction of the time.
Is accelerated TMS better than regular TMS?
Effectiveness is broadly similar between the two. Accelerated TMS offers a much shorter timeline, which makes it a better fit for patients who need faster relief or can't commit to six weeks of daily visits.
Is accelerated TMS FDA approved?
Yes. The FDA cleared iTBS protocols in 2018 and cleared BrainsWay's accelerated Deep TMS™ protocol for MDD in September 2025, building on years of standard TMS clearances.
