Welcome to the definitive resource on Repetitive Transcranial Magnetic Stimulation (rTMS). At ReACH Psychiatry, led by the expertise of Dr. Meena Gnanasekharan, we are committed to providing Bangalore and the rest of India with the most advanced, evidence-based neurostimulation treatments available today.
If you or a loved one are struggling with treatment-resistant depression, chronic anxiety, or OCD, this guide will help you understand how rTMS is shifting the paradigm of psychiatric care from "managing symptoms" to "rewiring for recovery."
Repetitive Transcranial Magnetic Stimulation (rTMS) is a non-invasive neuromodulation technique. Unlike systemic treatments (medication) that travel through the bloodstream, rTMS is a targeted physical intervention.
The Mechanism of Action
rTMS uses an electromagnetic coil placed against the scalp. This coil delivers brief, repetitive magnetic pulses—similar in strength to those used in an MRI machine.
A Brief History of FDA Approval
While rTMS is most famous for its success in treating Major Depressive Disorder, its efficacy extends across the psychiatric spectrum.
Treatment-Resistant Depression (TRD)
For many, standard antidepressants provide little relief. rTMS is specifically indicated for patients who have not achieved satisfactory improvement from prior antidepressant medications.
Anxiety Disorders
rTMS is increasingly used to calm the "overactive" brain associated with generalized anxiety. Research shows that stimulating the right side of the prefrontal cortex can significantly reduce physiological anxiety symptoms.

OCD and PTSD
By targeting the supplementary motor area or the anterior cingulate cortex, rTMS helps disrupt the repetitive thought loops characteristic of OCD.
Performance and Recovery
Mental health is also a physical game. We often see athletes struggling with the mental load of high-stakes competition.

Walking into a clinic for brain stimulation can feel intimidating, but the reality is a comfortable, outpatient experience.
The Clinic Environment
At ReACH Psychiatry in Bangalore, our rTMS suite is designed for relaxation. You remain fully awake and alert throughout the procedure. There is no anesthesia, no sedation, and no "recovery time" needed.
The First Session (Mapping)
Your first appointment involves "Motor Threshold Mapping." Dr. Meena Gnanasekharan or our specialized technicians will:
During the Session
You will hear a clicking sound (like a woodpecker) and feel a tapping sensation on your scalp. Many patients spend the session:
Consistency is the key to lasting neuroplasticity. Brain circuits don't change overnight; they require repetitive "exercise."
The Standard Course
Maintenance Sessions
Some patients benefit from "maintenance" sessions, once a week or once a month, to ensure the neural pathways remain active and prevent relapse.
rTMS is not an experimental "alternative" therapy; it is a gold-standard clinical treatment backed by decades of data.
Statistics for Depression
Statistics for Anxiety
Real-world outcomes show that adding rTMS to a standard care plan for anxiety can improve symptom reduction by up to 40% compared to medication alone.
One of the greatest advantages of rTMS is the lack of "systemic" side effects. Unlike medications, it does not cause weight gain, sexual dysfunction, nausea, or brain fog.
Common Side Effects (Mild)
Rare Risks
Contraindications
You cannot receive rTMS if you have non-removable metal in or near your head (excluding dental braces/fillings). This includes:
At ReACH Psychiatry, we use a comprehensive screening process to ensure patient safety and treatment efficacy.
Ideal Candidates
Screening Requirements
Dr. Gnanasekharan reviews your full medical history, focusing on:
medication is systemic (affecting the whole body), rTMS is focal. This means you avoid side effects like weight gain, sleepiness, or digestive issues. rTMS is often used along with medications to maximize the effect of it.
rTMS vs. ECT (Electroconvulsive Therapy)
ECT is highly effective but involves inducing a brief seizure under general anesthesia. It often requires a hospital stay and can lead to temporary memory loss. In contrast, rTMS requires no anesthesia, has no impact on memory, and allows you to drive yourself home immediately after the session.
rTMS vs. Ketamine/Esketamine Therapy
Ketamine acts on different neurotransmitters (glutamate) and provides rapid relief but can cause "dissociation" or blood pressure spikes during the session. rTMS offers a non-pharmacological alternative that builds long-term neural resilience through physical stimulation rather than chemical intervention.
At ReACH Psychiatry, we don't believe rTMS is a "magic wand" that replaces everything else. Instead, we see it as a powerful tool in a larger toolkit.
Dr. Meena Gnanasekharan works closely with each patient to integrate rTMS into a holistic plan that may include nutritional psychiatry, sleep hygiene, and therapy.

Frequently Asked Questions (FAQ) About rTMS
To help you make an informed decision about your mental health journey, Dr. Meena Gnanasekharan and the ReACH Psychiatry team have compiled the most common questions we receive from patients in Bangalore and across India.
Is rTMS therapy painful? Most patients describe the sensation as a light "tapping" or "pulsing" on the scalp. While it can feel unusual during the first few sessions, it is not described as painful. Any mild scalp sensitivity typically fades within the first week of treatment.
Will rTMS affect my memory or personality? Unlike ECT (Electroconvulsive Therapy), rTMS has no negative impact on memory or concentration. In fact, many patients report improved mental clarity and "brain fog" lifting as their depression or anxiety symptoms subside. It does not change your personality; it helps restore your brain to its healthy, functional state.
Can I drive myself home after a session? Yes. Because rTMS does not require sedation or anesthesia, you are fully alert immediately following the procedure. You can drive, return to work, or resume your daily exercise routine right after leaving our Bangalore clinic.
How soon will I start to feel better? While some patients notice a "lightening" of mood within the first two weeks, most clinical improvements occur between weeks four and six. Neuroplasticity—the process of rewiring the brain—takes time and consistent stimulation.
Is rTMS covered by insurance in India? Insurance coverage for psychiatric neuromodulation is evolving. We recommend checking with your specific provider regarding "neuromodulation" or "non-invasive brain stimulation" benefits. Our administrative team can provide the necessary documentation to assist with your claims.
What happens if I miss a session? While consistency (5 days a week) is ideal for the best outcomes, missing an occasional session due to travel or illness will not "reset" your progress. We simply resume the protocol as soon as you return.
Choosing where to receive rTMS is a significant decision. At ReACH Psychiatry, we combine world-class technology with the clinical oversight of Dr. Meena Gnanasekharan, a leader in advanced psychiatric care.
You don’t have to settle for "just getting by." If traditional treatments haven't provided the relief you deserve, rTMS may be the breakthrough you’ve been searching for.
