​Frequently Asked Questions on rTMS, TBS, dTMS & TDCS:

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.

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.

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.

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.

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

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.

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.

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.

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.

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.
