Accelerated TMS Effective for Treatment-Resistant Depression


Depression is one of the most pervasive mental health conditions worldwide, affecting millions of individuals. While traditional treatments such as medication and psychotherapy work for many, there is a significant group of patients who experience treatment-resistant depression (TRD). These individuals struggle to find relief even after multiple trials of antidepressants.

A groundbreaking study has recently explored the effectiveness of accelerated theta burst stimulation (aTBS), a condensed and high-intensity form of transcranial magnetic stimulation (TMS). The results indicate that this new approach could be a game-changer for those who have not responded to conventional treatments.

What is Transcranial Magnetic Stimulation (TMS)?

TMS is a non-invasive brain stimulation technique that has been used for years to treat depression. By using magnetic pulses to stimulate nerve cells in the brain, TMS can help regulate mood, reduce anxiety and alleviate symptoms of depression.

How Does TMS Work?

TMS works by delivering repetitive magnetic pulses to specific brain areas, particularly the left dorsolateral prefrontal cortex, which is responsible for mood regulation. This stimulation encourages neuronal activity in underactive regions of the brain, ultimately helping to reduce symptoms of depression.

Traditional vs. Accelerated TMS (aTBS)

Traditional TMS requires daily sessions over a period of four to six weeks, making it a slow and time-consuming process for patients. However, aTBS condenses this timeline, delivering short bursts of magnetic stimulation that is thought to be in sync with the brain's natural wave pattern. This means patients can see significant improvement in their symptoms within three weeks instead of several months.

Understanding Treatment-Resistant Depression

A third of individuals diagnosed with depression do not experience relief from traditional treatments, leading to treatment-resistant depression (TRD). This can be a frustrating and discouraging experience, but alternative treatment options like TMS and TBS provide new hope.

Why Some Patients Don’t Respond to Antidepressants

There are several reasons why some individuals do not respond to antidepressants:

  • Genetic Factors – Some people metabolize medications differently, making them less effective.
  • Neurobiological Differences – Certain brain structures and functions may contribute to depression resistance.
  • Chronic Stress and Trauma – Long-term stress can alter brain chemistry, making standard treatments ineffective.

Alternative Treatments for Depression

For those with TRD, there are several alternatives beyond medication, including:

  • Electroconvulsive Therapy (ECT) – A procedure using electrical pulses, requires anesthesia.
  • Ketamine Treatment– Shown to provide rapid relief for some patients.
  • Transcranial Magnetic Stimulation (TMS) – A non-invasive and effective outpatient option.

The Study on Accelerated Theta Burst Stimulation (aTBS)

A recent study published in JAMA Psychiatry examined the effectiveness of aTBS in treating treatment-resistant depression. The study aimed to determine whether aTBS could provide faster and more effective relief than traditional TMS.

Research Overview

The research focused on comparing aTBS with a sham procedure to evaluate its impact on depression symptoms. Participants underwent treatment in an outpatient setting, making it accessible and practical for real-world use.

Study Participants and Methodology

The research focused on comparing aTBS with a sham procedure to evaluate its impact on depression symptoms. Participants underwent treatment in an outpatient setting, making it accessible and practical for real-world use.

The study took place between July 2022 and June 2024 and included 89 outpatients with TRD. The participants were randomly assigned to either:



  • Active aTBS Group – Received actual TMS treatment.
  • Sham Procedure Group – Received a placebo treatment that mimicked TMS but did not deliver magnetic pulses.


All participants had a Hamilton Depression Rating Scale (HDRS) score above 16 and had failed to respond to at least one antidepressant trial.

Treatment Duration and Procedure

Patients in the active aTBS group underwent:

  • Three daily TMS sessions, each lasting six minutes and 18 seconds.
  • Two 30-minute breaks between sessions.
  • Total daily treatment time of 78 minutes.
  • 15 weekdays of treatment, totaling 45 sessions.

Results and Effectiveness

The study found that aTBS led to a significant reduction in depression symptoms:

  • Patients who received active aTBS experienced a 55% reduction in their depression scores.
  • 34% of the active treatment group achieved full remission (HDRS score ≤ 8), compared to only 16% in the sham group.
  • The treatment was well tolerated, with only mild side effects reported.

Advantages of aTBS Over Traditional TMS

Shorter Treatment Duration

One of the biggest benefits of aTBS is its efficiency. Traditional TMS requires six weeks of daily treatments, whereas aTBS condenses this into just three weeks.

No Need for Neuroimaging Equipment

Unlike some TMS protocols, aTBS does not require neuroimaging equipment to target the treatment area, making it more accessible for outpatient clinics.

High Success Rate in Remission

The remission rate for aTBS (34%) was more than double that of the sham group (16%), demonstrating that this condensed treatment is highly effective.

Potential Side Effects and Considerations

Common Side Effects

The study reported that aTBS was well tolerated, with only mild side effects, including:

  • Scalp discomfort or pain during treatment.
  • Mild headaches after sessions.
  • Temporary discomfort in the treated area.

Who is an Ideal Candidate for aTBS?

Individuals who may benefit most from aTBS include:

  • Patients diagnosed with treatment-resistant depression.
  • Those who have tried at least two antidepressants with no success.
  • Individuals seeking a non-invasive treatment alternative.

Future of TMS and aTBS in Mental Health Treatment

Expanding Accessibility to Patients

Given its shorter treatment time and high success rate, aTBS has the potential to become a leading treatment for TRD. More clinics worldwide are adopting this protocol, making it accessible to a larger population.

Ongoing Research and Potential Improvements

The study suggests further clinical trials are needed to optimize aTBS parameters and compare its effectiveness to traditional TMS. Future advancements may refine pulse frequencies, treatment durations, and individualized protocols.

Conclusion

The results of this study confirm that accelerated theta burst stimulation (aTBS) is a promising treatment for individuals with treatment-resistant depression. With its short treatment time, high remission rates, and minimal side effects, aTBS is paving the way for more accessible and effective depression treatments. As research in TMS and aTBS continues to evolve, the future of mental health treatment looks increasingly bright for those struggling with TRD.

Major Depressive Disorder (MDD) affects millions of people across the United States and worldwide. For many, the path to meaningful improvement can be long, often involving trial-and-error with medications, therapy, or traditional repetitive transcranial magnetic stimulation (rTMS) delivered once daily over several weeks. Now, there is an option that can compress effective treatment into days rather than weeks. MagVenture has received FDA clearance for Accelerated Transcranial Magnetic Stimulation (aTMS), and this development expands the tools Irvine Psychiatry and TMS can offer patients living with MDD. In this article we explain what aTMS is, how it differs from traditional TMS, what a typical treatment course looks like, who may benefit, and how to consider aTMS as part of a comprehensive depression care plan. We’ll also explore the important link between physical pain and emotional pain, because addressing both is the best way to improve outcomes for patients with depression. What is Accelerated TMS (aTMS)? Transcranial magnetic stimulation (TMS) is a noninvasive neuromodulation therapy that uses magnetic pulses to stimulate targeted regions of the brain involved in mood regulation. Conventional TMS protocols typically deliver a single daily session, weekday visits for 4-6 weeks using either high-frequency repetitive TMS (rTMS) or intermittent theta burst stimulation (iTBS). Accelerated TMS applies the same FDA-cleared TMS protocols but compresses treatment by delivering multiple sessions per day across a shorter overall timeframe. Rather than spreading treatment across several weeks, aTMS organizes sessions into a treatment window that usually lasts 5-15 days, depending on the protocol and clinical plan. The goal is the same, normalize dysfunctional circuits associated with depression, but with faster delivery of cumulative stimulation. How accelerated protocols work in practice The new FDA clearance supports a flexible approach clinicians can tailor to a patient’s needs. Typical elements include: Multiple sessions per day: Treatment regimens range from 2 to 10 sessions daily, allowing clinicians to achieve the required dose more quickly. Pulses per session: Each session usually delivers between 600 and 1,800 pulses. Pulses are the individual magnetic stimulations that modulate neural activity. Inter-session intervals: Sessions are separated by 15-50 minutes to allow short recovery windows between stimulations. Overall schedule: The condensed course typically spans 5–15 days, compared with 4-6 weeks for standard daily TMS. Protocol compatibility: aTMS uses the same FDA-cleared rTMS and iTBS protocols already proven effective for MDD. Navigation options: aTMS can be done with or without MRI-guided neuronavigation depending on clinical preference and available equipment. Why accelerate treatment? There are several advantages to accelerated delivery: Speed of symptom relief: For many patients, faster symptom reduction is a critical clinical and practical benefit. In acute situations such as severe depression with suicidal thoughts or marked functional decline a faster-acting therapy can be lifesaving. Reduced burden of time: Condensing treatment into days reduces the duration of repeated clinic visits over months, which can be a major barrier for people with busy schedules, caregiving responsibilities, or transportation challenges. Improved adherence: Shorter overall treatment windows can increase the likelihood patients complete the recommended course, which supports better outcomes. Rapid response for nonresponders: aTMS may be advantageous for patients who have not responded to medication trials or who need quicker evaluation of a neuromodulation strategy. Who is a candidate for aTMS? aTMS is intended for adults diagnosed with Major Depressive Disorder who are appropriate candidates for TMS. Potential candidates include: People with moderate-to-severe depression who did not achieve adequate response with antidepressant medications or psychotherapy. Individuals who need a faster approach due to symptom severity or life circumstances. Patients who prefer a short, intensive course rather than daily visits for several weeks. As with all medical treatments, candidacy is determined through a comprehensive clinical assessment that considers medical history, psychiatric comorbidities, seizure risk, presence of metal implants, and concurrent medications. At Irvine Psychiatry, we follow evidence-based screening protocols to ensure safety and maximize likelihood of benefit. Efficacy and safety: what the evidence shows The same stimulation protocols used in aTMS (rTMS, iTBS) have robust evidence supporting their use in MDD. Accelerated protocols are an emerging area of research: studies and clinical experience indicate many patients can achieve meaningful symptom relief faster when aTMS is used, though response varies by individual. The FDA clearance reflects that manufacturers have demonstrated aTMS delivery is safe when performed under specified conditions. Common side effects mirror those of standard TMS: mild scalp discomfort or headache during or after treatment, transient fatigue, and rare risk of seizure (low but present). Clinicians minimize risk by adhering to safety guidelines, choosing appropriate stimulation parameters, and monitoring patients closely during sessions. What to expect during aTMS at Irvine Psychiatry and TMS If you are referred for aTMS, here’s a typical patient journey: Consultation and evaluation: You come into the clinic for a full evaluation. Dr. Creighton reviews your psychiatric history, medication profile, and potential contraindications to TMS. Individualized treatment plan: Based on your clinical presentation, we select rTMS or iTBS protocol, number of daily sessions, pulse counts, and overall schedule. Orientation session: You’ll meet the treatment team, learn what to expect, and undergo baseline assessments of mood and functioning. Treatment days: Sessions last 20-40 minutes each depending on protocol. Breaks of 15-50 minutes occur between sessions. Patients relax in a comfortable chair during treatment and are observed by staff. Monitoring and follow-up: Mood, side effects, and functioning are assessed throughout and after the course to guide ongoing care. Integrating aTMS into comprehensive care aTMS is most effective when integrated into a broader treatment strategy that can include psychotherapy, medication management, lifestyle interventions, and supports for sleep, nutrition, and activity. Rapid improvements from aTMS can create a window in which psychotherapy and behavioral changes become more feasible and effective. Addressing cost and access Insurance coverage for TMS (including aTMS) differs across plans and is evolving. Some payers cover FDA-cleared TMS for treatment-resistant depression under specific criteria. Our administrative team at Irvine Psychiatry and TMS can assist patients with benefits verification, prior authorization where needed, and exploring financing options. When to consider immediate care If you or someone you care about is experiencing active suicidal ideation, severe psychomotor slowing, inability to perform basic self-care, or other signs of a psychiatric emergency, please seek immediate help: call local emergency services or the nearest emergency department.  Accelerated TMS may be part of urgent treatment planning for some patients, but emergency-level care should be the first step when risk is imminent.

Have you ever felt like you’ve tried everything to manage your mental health but still couldn’t find lasting relief? If so, you're not alone. Transcranial Magnetic Stimulation (TMS) therapy might be the game-changer you’ve been looking for. This innovative, non-invasive treatment has helped countless individuals experience long-term relief from depression, anxiety, and more. But what exactly makes TMS so powerful? Let’s dive in and see what the studies have to say. How TMS Therapy Works The Science Behind TMS TMS therapy uses magnetic pulses to stimulate specific areas of the brain linked to mood regulation. Think of it like a reset for your computer but for your brain. The repetitive stimulation encourages neural activity in areas that are known to be underactive in people with depression. How It Rewires the Brain One of the coolest things about TMS is its ability to promote neuroplasticity, which is the brain’s ability to form new connections. Over time, this rewiring can lead to more stable and positive moods. Proven Benefits of TMS Therapy Effective for Treatment-Resistant Depression If traditional treatments haven’t worked for you, TMS could be a beacon of hope. Studies show that TMS therapy is highly effective for people with treatment-resistant depression, offering significant symptom relief where medications fail. Reducing Anxiety Symptoms While TMS is primarily known for treating depression, it’s also been proven to help reduce anxiety symptoms. By calming overactive brain circuits, it brings a sense of balance to your emotional state. Enhancing Cognitive Function Improved focus and mental clarity are often reported by people undergoing TMS therapy. This is particularly beneficial for those whose depression has affected their ability to think clearly or retain memories. Improving Sleep Patterns Struggling with sleep? TMS therapy can help regulate your sleep-wake cycles, making it easier to get a good night’s rest and wake up feeling refreshed. Sleep is a critical component of stable mood and mental clarity. Long-Term Effects of TMS Therapy Sustained Relief from Depression The effects of TMS therapy aren’t just short-term. Many patients experience lasting relief long after completing their treatment sessions. Clinical studies show that the positive effects can extend for months or even years. Improved Quality of Life Imagine being able to enjoy your favorite activities again without the weight of depression holding you back. TMS therapy doesn’t just improve symptoms, it helps people regain their lives. Neuroplasticity and Brain Health By encouraging neuroplasticity, TMS enhances overall brain health. This means your brain becomes more adaptable and resilient to future stressors. What the Studies Say Key Clinical Studies on TMS Numerous studies highlight the efficacy of TMS. For example, one study found that 60% of participants experienced significant symptom improvement, with 30% achieving full remission. This has been replicated by several studies. Long-Term Success Rates The long-term success rates of TMS are impressive. Follow-up studies reveal that many patients maintain their progress, especially with occasional maintenance sessions. Comparing TMS to Other Treatments Compared to medications, TMS offers fewer side effects and longer-lasting results. Plus, it directly treats the underlying issue that’s leading to depression. Who Can Benefit from TMS Therapy? Ideal Candidates TMS is a great option for adults with treatment-resistant depression. It’s also suitable for those who prefer drug-free alternatives or can’t tolerate medication side effects. Not Just for Depression: Other Conditions TMS Helps TMS isn’t just for depression. It’s been studied and approved to treat conditions like anxiety, OCD, PTSD, and even chronic pain. Side Effects and Safety Common Side Effects TMS therapy is generally well-tolerated. The most common side effects include mild headaches and scalp discomfort, which usually go away after a few sessions. Long-Term Safety Evidence Studies confirm that TMS is safe for long-term use. Unlike medications, it doesn’t come with risks of addiction or serious systemic side effects. TMS Therapy in Practice What to Expect During Treatment A typical TMS session lasts about 20-40 minutes. You’ll sit in a comfortable chair while a technician places a magnetic coil on your head. There’s no downtime you can go right back to your daily activities afterward. Maintenance Sessions Some patients require periodic maintenance sessions to keep their progress on track. These can be scheduled depending on each individual’s specific needs. The Future of TMS Therapy Advances in Technology and Protocols The field of TMS therapy is evolving rapidly. New protocols and more precise targeting methods are making treatments even more effective. Broader Applications in Mental Health Researchers are exploring the use of TMS for a wider range of conditions, including substance use disorders and neurodegenerative diseases. Conclusion TMS therapy is more than just a treatment, it’s a lifeline for those seeking long-term relief from mental health challenges. Whether you’re dealing with depression, anxiety, or another condition, TMS offers hope, backed by solid science and real-world success stories.

When you're struggling with your mental health, the last thing you should have to fight is your own insurance company. But for thousands of Californians, that fight is their reality, and a recent class action lawsuit is highlighting the reasons behind it. In November 2025, four policyholders filed a lawsuit against Blue Shield of California and Magellan Health, alleging that they maintained what's known as a "ghost network" of mental health providers. According to the complaint, the insurance companies published directories listing psychiatrists and therapists who either don't exist, have moved on, or simply don't accept new patients. When real people in real crisis tried to use their coverage, they found nothing on the other end. The lawsuit puts it plainly: "When people in need are unable to find an in-network mental health provider, urgent mental health treatment is often delayed and, at worst, abandoned completely." That sentence should stop you in your tracks. What is a ghost network and why does it matter? A ghost network is an insurance provider directory that looks robust on paper but falls apart the moment a patient tries to access it. You call the first name on the list and get an out-of-service number. You call the second and hear they're not accepting new patients. You call the third and they've never heard of your insurance plan. You are not able to get the services you need from the network that you are covered by. You either give up and don’t get treatment, your symptoms worsen and you end up in emergency care before you can find an in network doctor, or you pay for care out of pocket. Meanwhile, the insurance company benefits. They attract customers with the appearance of comprehensive mental health coverage. They collect high premiums. And they don’t pay out claims because the doctors that would generate those claims don't actually exist in any functional sense. This should be unacceptable to all those involved. The people hurt most by this are not statistics. They are someone's parent, partner, or child. When people need help, and ask for help, they deserve to find help, not to be sent on a wild goose chase that leads to a dead end. This is a mental health access crisis Mental health care is not optional. Conditions like anxiety, depression, OCD, PTSD, and bipolar disorder are medical realities that require real treatment, not a runaround. Delaying care doesn't make these conditions go away. It makes them worse. This ends up costing us in many other ways. For most patients, the window between deciding to seek help and actually getting it is narrow. Every disconnected phone number and every full practice is a door closing on someone who was ready to open one. The downstream consequences, including worsening symptoms, emergency interventions, and hospitalization, cost the system far more than timely outpatient care ever would. And they cost patients something money can't replace. Ghost networks are not a billing technicality. They are a public health issue. And they are illegal. Know your rights as a mental health patient in California If you're covered by a Blue Shield of California policy and encountered barriers finding an in-network mental health provider, you may be part of the class described in this lawsuit. Speaking with a consumer rights or insurance attorney can help you understand your options. More broadly, here is what every patient should know. Your insurance plan is required by law to maintain an accurate, up-to-date provider directory. Under California and federal mental health parity laws, your insurer must provide mental health coverage no more restrictive than coverage for comparable physical health conditions. You have the right to request an out-of-network exception if your insurer cannot connect you with an available in-network provider. You can file a complaint with the California Department of Managed Health Care at dmhc.ca.gov if your insurer fails to provide timely access to mental health care. Don't accept "no available providers" as a final answer.
