Depression affects over 280 million people worldwide, and traditional treatments don’t work for everyone. Antidepressants help many patients but leave others with minimal improvement despite trying multiple medications rTMS therapy,.
Therapy provides tools for coping but doesn’t always resolve the underlying brain chemistry issues. For people who haven’t responded to standard treatments, rTMS therapy offers a non-invasive option that targets depression at the neurological level.
What rTMS Therapy Actually Is
Repetitive transcranial magnetic stimulation uses magnetic pulses to stimulate specific brain regions. A coil placed against the scalp generates targeted magnetic fields that pass through the skull and activate neurons in the prefrontal cortex—the brain area involved in mood regulation that shows reduced activity in people with depression.
The technology isn’t new, but its application for depression has expanded significantly. The FDA first approved TMS for treatment-resistant depression in 2008. Since then, research has refined protocols, identified optimal stimulation sites, and developed better equipment. By 2025, rTMS treatment has become more accessible and more effective than earlier versions.
Unlike electroconvulsive therapy, which uses electrical currents and requires anaesthesia, rTMS doesn’t cause seizures and patients remain fully awake during treatment. Unlike medication, it doesn’t circulate through the entire body causing systemic side effects. The magnetic stimulation stays localised to targeted brain regions.

How rTMS Treatment Works
Sessions typically last 20-40 minutes. Patients sit in a comfortable chair while a technician positions the magnetic coil against the head. The coil delivers rapid magnetic pulses that feel like tapping sensations on the scalp. Most people describe it as mildly uncomfortable rather than painful, though intensity varies between individuals.
Standard protocols involve daily sessions five days per week for four to six weeks. This adds up to 20-30 total sessions. The repetitive nature matters – single sessions don’t produce lasting effects. The cumulative stimulation gradually changes how neurons fire and communicate in the targeted brain regions.
For those seeking TMS therapy Brooklyn and other metropolitan areas typically offer multiple specialized clinics, making it easier to find convenient locations for the daily treatment commitment.
Different protocols exist for different conditions. High-frequency stimulation typically targets the left dorsolateral prefrontal cortex to increase activity in areas that show hypoactivity in depression.
Low-frequency protocols might target the right hemisphere to reduce overactivity in certain regions. Theta burst stimulation, a newer protocol, delivers pulses in specific patterns that may work faster than standard approaches.
Does rTMS Work for Depression?
Research shows rTMS therapy produces meaningful improvement for many patients who haven’t responded to medications. Studies report remission rates, complete symptom resolution, ranging from 30-40% in treatment-resistant depression. Another 20-30% experience significant improvement even if they don’t achieve full remission. This means roughly 50-70% of patients get substantial benefit.
These numbers matter because they apply to people who already failed multiple medication trials. Standard antidepressants achieve remission in about 30% of patients in their first trial, with decreasing success rates in subsequent attempts. For someone on their third or fourth medication failure, traditional options look increasingly bleak. rTMS treatment provides meaningful hope where other approaches have failed.
Response doesn’t happen immediately. Most patients notice gradual improvement over weeks rather than sudden shifts. Some report feeling slightly better after the first week. Others don’t notice changes until they’ve completed 15-20 sessions. A small percentage don’t respond at all despite completing the full protocol.
Long-term outcomes vary. Some patients maintain improvement for months or years after treatment. Others experience symptom return and need maintenance sessions, typically once monthly or quarterly, to sustain benefits. This pattern resembles medication where stopping often leads to relapse.
The Science Behind Why It Works
Depression involves disrupted communication between brain regions. The prefrontal cortex, which handles executive function and emotional regulation, shows reduced activity and connectivity in depressed individuals. Regions involved in reward processing and motivation also function differently.
Magnetic stimulation triggers action potentials in neurons, causing them to fire. Repeated stimulation over weeks strengthens certain neural pathways while weakening others through mechanisms similar to learning and memory formation. This process, called neuroplasticity, allows the brain to form new patterns of activity.
Brain imaging studies show that successful rTMS therapy increases activity in the dorsolateral prefrontal cortex and strengthens connections between this region and deeper brain structures involved in emotion. These changes correlate with symptom improvement, suggesting the treatment genuinely alters the neural circuits underlying depression rather than just providing placebo effects.
RTMS Side Effects and Safety Concerns
Most rtms side effects are mild and temporary. The most common complaint is scalp discomfort or headache at the stimulation site. This typically lessens as patients get used to the sensation. Over-the-counter pain relievers manage any lingering discomfort.
Some patients experience facial twitching during pulses, particularly early in treatment. This happens because facial nerves run near the stimulation site. Adjusting coil position usually resolves this issue.
Common temporary side effects:
- Scalp tenderness or mild headache
- Tingling or twitching in facial muscles
- Lightheadedness immediately after sessions
- Fatigue during the treatment course
- Brief concentration difficulties
Seizure represents the most serious potential risk, though it remains extremely rare – occurring in roughly 1 in 30,000 sessions. Risk increases for patients with seizure history or those taking medications that lower seizure threshold. Proper screening identifies high-risk individuals who shouldn’t receive treatment.
Unlike antidepressants, rTMS doesn’t cause weight gain, sexual dysfunction, emotional blunting, or the numerous other side effects that make many patients discontinue medications. Unlike ECT, it doesn’t affect memory or require anaesthesia. The side effect profile makes it tolerable for most patients.
RTMS Benefits Beyond Depression
While depression remains the primary indication, research explores rTMS for other conditions. Obsessive-compulsive disorder has FDA approval for TMS treatment, with protocols targeting different brain regions than depression protocols.
Anxiety disorders show promise in clinical trials. PTSD treatment protocols are under investigation. Some studies examine rTMS for smoking cessation, with stimulation targeting regions involved in craving and impulse control. Chronic pain conditions may respond to protocols that modulate pain processing pathways.
Cognitive enhancement represents an emerging area. Some protocols appear to improve memory and executive function in healthy individuals, though this application remains experimental and raises ethical questions about enhancement versus treatment.
Who Should Consider rTMS Therapy
Good candidates typically include people who haven’t responded adequately to at least two antidepressant trials. Insurance often requires documented medication failures before covering rTMS treatment. Some people choose it earlier because they cannot tolerate medication side effects or prefer non-pharmaceutical approaches.
Patients need to commit to the time requirements. Daily sessions for 4-6 weeks demands scheduling flexibility. Missing multiple sessions reduces effectiveness. The treatment works best when protocols are followed consistently.
Ideal candidates often:
- Have tried multiple antidepressants without adequate response
- Experience intolerable medication side effects
- Prefer non-drug treatments when possible
- Can commit to daily sessions for several weeks
- Don’t have metal implants in the head or seizure disorders
Pregnancy isn’t necessarily a contraindication, though data remains limited. Some women choose rTMS to avoid medication exposure during pregnancy. Metal dental fillings don’t pose problems, but cochlear implants, aneurysm clips, or other metal objects near the head require careful evaluation.
What Treatment Actually Involves
Initial consultation includes psychiatric evaluation, medical history review, and discussion of previous treatments. Providers map the optimal stimulation site by measuring head dimensions and locating the motor cortex. This mapping session determines where to position the coil for treatment.
The first session establishes motor threshold – the minimum intensity that causes thumb movement when stimulating the motor cortex. Treatment intensity bases itself on this individual threshold, ensuring adequate stimulation without excessive discomfort.
Most clinics schedule appointments at the same time each day to maintain consistency. Patients can drive themselves to and from appointments. They can return to normal activities immediately after sessions. Some people go straight to work. Others prefer scheduling late-day appointments if they experience temporary fatigue.
Cost varies significantly by location and insurance coverage. Treatment courses typically run £5,000-£10,000 in the UK without insurance. Many insurance plans now cover rTMS therapy for treatment-resistant depression, though prior authorisation requirements and out-of-pocket costs vary. Checking coverage details before starting treatment prevents financial surprises.
Moving Forward With Treatment Decisions
rTMS therapy represents a genuine advance for treatment-resistant depression. It works through measurable brain changes rather than placebo alone. The side effect profile beats medications for most patients. Success rates justify trying it when other treatments have failed.
But it’s not magic. Some patients don’t respond. Benefits may require maintenance sessions. The time commitment proves difficult for some people. And like all treatments, it works better for some individuals than others for reasons we don’t fully understand yet.
For someone struggling with depression that hasn’t responded to standard treatments, discussing rtms treatment with a psychiatrist makes sense. It won’t work for everyone, but for many people, it provides relief when nothing else has helped.
