Question 1

What are rTMS, Deep TMS, TBS and tDCS?

Accepted Answer

These are advanced, non-invasive brain stimulation techniques used to treat various psychiatric and neurological conditions by modulating specific brain circuits involved in symptoms.

rTMS (Repetitive Transcranial Magnetic Stimulation)
rTMS uses focused magnetic pulses to stimulate or regulate specific areas of the brain involved in conditions such as depression, OCD, anxiety disorders, addiction, migraine and stroke rehabilitation.
Deep TMS (dTMS)
Deep TMS is an advanced form of TMS that can stimulate deeper brain structures implicated in resistant depression and OCD. At Somnos RTMS Clinic, we use a Double Cone Coil (DCC) Deep TMS system for deeper cortical stimulation in selected patients. Deep TMS is particularly useful in certain treatment-resistant cases and specific brain targets that are difficult to reach with conventional rTMS.
Theta Burst Stimulation (TBS)
Theta Burst Stimulation is a newer and more time-efficient form of rTMS. While conventional rTMS sessions may last 20–45 minutes, TBS sessions usually take only 3–5 minutes while offering comparable or sometimes superior clinical outcomes.
tDCS (Transcranial Direct Current Stimulation)
tDCS uses a very mild electrical current delivered through electrodes placed on the scalp. It is painless, safe and often used in depression, anxiety disorders, cognitive rehabilitation, memory problems, stroke rehabilitation and language rehabilitation.

Question 2

Which conditions can be treated with non- invasive Neuromodulation (rTMS, TBS, dTMS, TDCS)?

Accepted Answer

These treatments may be helpful in:
Depression (including treatment-resistant depression)
Obsessive Compulsive Disorder (OCD)
Anxiety Disorders
Panic Disorder
PTSD
Addiction (Alcohol, Nicotine, Cannabis and other substances)
Chronic Pain
Migraine
Stroke Rehabilitation
Cognitive Impairment
Memory Problems
Language Rehabilitation after Stroke
Certain Movement Disorders
The suitability of a particular treatment depends on the individual's diagnosis, severity, treatment history and clinical assessment.

Question 3

Are these treatments (rTMS, TBS, dTMS, TDCS) safe?

Accepted Answer

Yes. rTMS, Deep TMS, TBS and tDCS are considered safe, non-invasive and well tolerated when administered under proper medical supervision.
Unlike Electroconvulsive Therapy (ECT), these treatments:
Do not require anesthesia
Do not require hospitalization
Do not cause memory loss
Allow patients to resume normal activities immediately after treatment
Most patients experience only mild scalp discomfort or transient headache during the initial sessions.

Question 4

How many sessions are required?

Accepted Answer

rTMS
Most patients require approximately 30–40 sessions for optimal results.
Deep TMS
Most patients require approximately 30–40 sessions depending on diagnosis and severity.
Theta Burst Stimulation (TBS)
Typically 30–40 sessions are recommended, although the treatment duration per session is much shorter.
tDCS
Most patients require 20–30 sessions depending on the condition being treated.
Some patients may benefit from additional maintenance or booster sessions to sustain improvement.

Question 5

How long does each session take?

Accepted Answer

rTMS
20–45 minutes per session
Deep TMS
20–45 minutes per session
TBS
Usually 3–5 minutes per session
tDCS
Typically 20–30 minutes per session

Question 6

What is the success rate?

Accepted Answer

While no treatment can guarantee results, our clinical experience at Somnos RTMS Clinic has been encouraging, particularly among patients who are regular, punctual and complete the recommended treatment course.
Depression
Approximately 80% of patients experience significant improvement in symptoms.
OCD
Approximately 60–70% of patients experience meaningful improvement during the initial treatment course.
With appropriate booster sessions and continued follow-up, clinical response rates in OCD often exceed 80% in suitable patients.
Treatment outcomes vary depending on illness duration, severity, comorbidities, medication adherence and attendance consistency.

Question 7

What are rTMS Booster Sessions?

Accepted Answer

Booster sessions are maintenance sessions provided after the primary treatment course has been completed.
These sessions help:
Maintain improvement
Reduce chances of relapse
Enhance long-term outcomes
Improve durability of treatment response
Patients with OCD, recurrent depression and chronic illnesses often benefit significantly from booster protocols.

Question 8

What is the cost of treatment?

Accepted Answer

Standard rTMS
₹16,500 for 10 sessions
Accelerated rTMS
₹17,500 for 10 sessions
Accelerated rTMS (Extended Protocol)
₹25,000 for 15 sessions
Deep TMS
₹19,500 for 10 sessions
Accelerated Deep TMS
₹21,500 for 10 sessions
Theta Burst Stimulation (TBS)
₹19,500 for 10 sessions
Accelerated Theta Burst Stimulation
₹21,500 for 10 sessions
tDCS
₹800 per session
tDCS with Cognitive Training / Cognitive Tasks
₹1,000–₹1,200 per session
The exact protocol and number of sessions are individualized based on the condition being treated, treatment goals and clinical assessment.

Question 9

Can I continue my medications during treatment?

Accepted Answer

Yes. In most cases patients continue their prescribed medications during rTMS, Deep TMS, TBS or tDCS treatment.
These therapies often work alongside medications and psychotherapy to improve overall outcomes.

Question 10

When do patients start noticing improvement?

Accepted Answer

Some patients notice improvement within the first 1–2 weeks.
However, most patients begin experiencing meaningful clinical benefits after 15–20 sessions, with continued improvement throughout the treatment course.

Question 11

Who should avoid these treatments?

Accepted Answer

Certain patients may require special precautions, including those with:
Metallic implants in the head
Certain implanted neurostimulators/ pacemakers
Specific seizure disorders
Unstable neurological conditions
A detailed clinical evaluation is always performed before starting treatment.
