How rTMS Therapy Helps Treatment-Resistant Depression

If you have tried antidepressants, therapy, or both, and still feel like nothing has worked, you are not alone, and you have not run out of options.

Treatment-resistant depression affects a significant portion of people living with major depressive disorder. For those individuals, repetitive transcranial magnetic stimulation, or rTMS, represents one of the most important advances in mental health treatment in recent decades. It is non-invasive, does not require medication, does not involve anaesthesia, and has been studied extensively as an effective clinical option when conventional approaches fall short.

This blog explains exactly how rTMS therapy works, what the research shows, who it is suited for, what a course of treatment looks like, and what to expect along the way.

What Is Treatment‑Resistant Depression?

Treatment‑resistant depression (TRD) is a form of major depressive disorder that doesn't get better after trying at least two different antidepressant medications at proper doses and durations. Roughly 30% of people with major depression experience inadequate relief from standard antidepressants, and many others only improve partially.

For people with TRD, following typical treatment steps can feel discouraging, yet it's not a personal failure. It's a recognized clinical condition that often requires alternative evidence‑based treatments, such as repetitive transcranial magnetic stimulation (rTMS), psychedelic-assisted therapy, or psychological therapy.

What is rTMS Therapy?

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation therapy that uses focused, repeated electromagnetic pulses to stimulate specific regions of the brain associated with mood regulation.

The procedure does not involve surgery, medication, or anaesthesia. You remain fully awake and alert throughout the session. Most people can return to work, drive, and continue their normal activities immediately afterward.

The word "repetitive" in rTMS is clinically significant. It is not a one-time intervention. The magnetic pulses are applied consistently across multiple sessions, over several weeks, and this sustained repetition is what creates lasting neurological change, a process known as neuroplasticity. rTMS and brain neuroplasticity work hand in hand, making this treatment an effective approach for those with treatment-resistant depression.

Each rTMS session lasts 20-40 minutes, with no downtime required, and over several sessions, you’ll experience progressive improvements in your mood.

How Does rTMS Actually Work? The Science Explained Simply

Understanding how rTMS works helps remove the mystery from the process and builds genuine confidence in the approach.

The Brain Region Targeted: The Prefrontal Cortex

The left dorsolateral prefrontal cortex (DLPFC) regulates mood, cognitive flexibility, and executive function, and is often underactive in depression. This underactivity profoundly impacts how individuals think, feel, and engage with the world.

What the Pulses Dor

rTMS uses electromagnetic pulses to stimulate nerve cells in the underactive DLPFC, encouraging more active firing. Over time, this rebalances the brain's circuits by promoting neuroplasticity, allowing the brain to reorganize and form healthier neural connections.

High-Frequency vs. Low-Frequency Stimulation

High-frequency rTMS (above 5 Hz) stimulates the underactive DLPFC, while low-frequency rTMS (below 1 Hz) quiets overactive brain regions. The appropriate frequency is determined by your clinician after a thorough assessment.

We recommend taking rest during your rTMS treatment sessions and avoiding physically intense activities to support the therapy's effectiveness.

What Conditions Can rTMS Help With?

While rTMS is most widely studied and applied for treatment-resistant depression, its applications in mental health care are broader:

• Major Depressive Disorder (MDD) — particularly treatment-resistant cases

• Anxiety disorders — including generalised anxiety disorder and panic

• Post-Traumatic Stress Disorder (PTSD) — an area of growing clinical evidence

• Obsessive-Compulsive Disorder (OCD) — specific protocols have shown efficacy

• Depression with concurrent chronic pain — given the connection between emotional and physical experience

At New Track Selfcare, rTMS therapy is considered for individuals presenting with depression, anxiety, and PTSD as part of a personalised treatment pathway. Whether rTMS is the right fit for you is determined through a careful clinical assessment, not a general checklist. Psychedelic therapy and neuroplasticity are also gaining attention for their potential to complement rTMS in promoting brain health and resilience.

What Are the Side Effects of rTMS?

rTMS is widely regarded as a safe and well-tolerated treatment. The most commonly reported side effects are mild and typically diminish as treatment progresses:

• Mild headache — the most common side effect, usually responds to standard over-the-counter pain relief and improves over the first week

• Scalp discomfort or tingling at the site of stimulation, particularly in early sessions

• Facial twitching or jaw movement in sync with the pulses, not painful, and does not continue after the session ends

• Brief dizziness or light-headedness immediately after a session, which passes quickly

rTMS does not cause memory impairment, does not require recovery time, and does not involve any substance entering the body. The most serious potential adverse event, seizure, is rare and significantly mitigated through thorough pre-treatment screening. Hearing protection is provided during sessions to manage the clicking sound produced by the device.

Your clinical team will discuss any individual considerations with you before treatment begins.

Who Is a Good Candidate for rTMS?

rTMS may be an appropriate option if you:

• Have been diagnosed with major depressive disorder and have not experienced adequate relief from antidepressant medications

• Are you dealing with depression alongside anxiety or PTSD that has not fully responded to conventional treatment

• Cannot tolerate certain medication side effects or prefer a non-pharmacological approach

• Are looking for a complementary approach to support your existing therapy

• Have been assessed as medically suitable, with no contraindications such as metal implants near the head or a history of seizures

rTMS is not suitable for everyone, which is why the clinical assessment is the essential starting point. 

Frequently Asked Questions About rTMS for Depression

How many rTMS sessions will I need?

A standard rTMS course typically involves daily sessions five days per week over four to six weeks, approximately 20 to 30 sessions in total. The exact number will be determined based on your assessment and how your treatment progresses. You may wonder: "How many rTMS therapy number of sessions will I need?" The answer depends on how your brain responds to the therapy and your ongoing progress.

How quickly does rTMS work?

Many patients begin noticing changes within the second or third week of treatment, though individual timelines vary. The full benefit of a treatment course often continues to develop even after the sessions conclude.

Is rTMS painful? 

Most people experience rTMS as comfortable. The most commonly reported sensation is a rhythmic tapping or mild pressure on the scalp. Mild headaches can occur early in treatment and typically improve within the first week.

Can rTMS be combined with my current antidepressant medication?

In many cases, yes. rTMS and antidepressant medications can be used together, and some evidence suggests combining them may produce better outcomes than either approach alone. This will be reviewed carefully during your clinical assessment.

Does rTMS work for PTSD and anxiety as well as depression?

Yes. While rTMS has the strongest evidence base for treatment-resistant depression, it is also applied clinically for PTSD, generalised anxiety disorder, and OCD. Your clinician will determine the most appropriate protocol for your specific presentation.

Conclusion

If you have been living with treatment-resistant depression for months or years, it can feel as though the landscape of possible relief is narrowing. rTMS is not a guarantee, no treatment is, but it represents a genuinely different pathway, grounded in decades of research, that works at the level of the brain itself.
