Deep Transcranial Magnetic Stimulation (Deep TMS) is a non-invasive treatment method that uses magnetic fields to send direct stimuli to brain cells in order to modulate brain activity. It differs from traditional TMS in that the magnetic fields can reach deeper regions of the brain. Deep TMS is used to treat psychiatric disorders such as depression, anxiety, obsessive-compulsive disorder (OCD), and addiction. This method offers patients a safe treatment without the need for surgery and has generally been shown to be effective in patients who do not respond to medication. During treatment, the patient wears a headpiece, and magnetic pulses are directed at specific brain regions.
This treatment is painless and is usually administered in sessions lasting several weeks. Deep TMS helps alleviate patients’ symptoms by balancing neurotransmitter levels in the brain.
Deep TMS offers promising results, particularly for patients who are resistant to medication. Sessions typically last 20–30 minutes, and patients can continue their normal daily activities throughout the treatment process. The side effects of this method are minimal and are mostly limited to headaches or a mild sensation of discomfort in the treatment area. One of the advantages of Deep TMS is that it does not require brain surgery and offers patients a rapid recovery process. Furthermore, its effectiveness in treating long-term psychiatric disorders has been proven, as it promotes the reorganization of neural networks in the brain. This method, which has received FDA approval specifically for the treatment of depression and OCD, provides a more personalized and effective treatment by targeting specific brain regions unique to each individual.
For Which Conditions Is Deep TMS Used?
Deep Transcranial Magnetic Stimulation (Deep TMS) is used in the treatment of many psychiatric and neurological disorders. Its effectiveness has been proven particularly in the treatment of major depression, offering a powerful alternative for patients who do not respond to medication. The conditions treated include:
- Major Depression,
- Obsessive-Compulsive Disorder (OCD),
- Anxiety Disorders,
- Post-Traumatic Stress Disorder (PTSD),
- Bipolar Disorder,
- Neurological Disorders,
- Alcohol Dependence,
- Tobacco Dependence,
- Cocaine Dependence,
- Drug Dependence,
- Multiple Sclerosis (MS) – Relief from Fatigue,
- Neuropathic Pain,
- Autism—Improving Communication Skills,
- Parkinson's Disease,
- Alzheimer’s Disease.
Schizophrenia—negative symptoms, and other treatment-resistant neuropsychiatric disorders—have received CE approval, and with positive results from clinical trials, its use in treatment is becoming increasingly widespread.
Provocation-Based Deep TMS Therapy
During deep transcranial magnetic stimulation (Deep TMS) treatment, a provocation procedure performed by a specialist clinical psychologist systematically and controllably triggers the patient’s symptoms on a temporary basis. During this process, the individual is exposed to triggering stimuli that can activate his symptoms. Various images, videos, or imagery techniques may be used for this purpose.
For example, a patient suffering from obsessive-compulsive disorder (OCD) with obsessions related to dirt and germs can have his obsessions activated by being shown images with dirt and germ themes. Similarly, a patient with cocaine addiction can have his cravings triggered by being asked to imagine using cocaine.
This approach activates brain circuits associated with the symptoms, thereby supporting the Deep TMU device in more effectively stimulating the targeted brain regions and regulating brain activity. Although its effect cannot be isolated on its own, research suggests that Deep TMU treatment performed with provocation may be more effective than treatments without provocation. The provocation technique can be used as a supportive method alongside Deep TMS in the treatment of various disorders—including obsessive-compulsive disorder and addiction—as deemed appropriate by the physician.
Differences Between Deep TMS and Conventional TMS
The differences between Deep TMS (Transcranial Magnetic Stimulation) and Conventional TMS can be summarized under the following headings:
Magnetic Field Depth: Deep TMS can reach deeper regions of the brain compared to classical TMS. While classical TMS affects only superficial cortical areas, deep TMS can also stimulate structures in the brain’s deeper layers.
Scope of Treatment: While Deep TMS can be used to treat major depression as well as obsessive-compulsive disorder (OCD), addiction, anxiety disorders, and more complex neurological conditions, conventional TMS is generally used more widely only for the treatment of depression.
Device Design: Deep TMS uses a special coil called an H-coil to deliver the magnetic field deeper into the brain. Conventional TMS, on the other hand, typically uses a flat coil that provides superficial stimulation.
Area of Effect: Deep TMS can affect a broader area of the brain and has a stronger effect on different brain structures. Conventional TMS, on the other hand, focuses on a more limited area.
Side Effects: Both methods are non-invasive and do not require surgery; however, because Deep TMS targets a larger area, treatment-related side effects may vary. Generally, though, side effects are minimal with both methods.
These differences allow for treatment selection based on the patient’s condition and the targeted brain region.
Why Is Deep TMS Important in Addiction Treatment?
Deep TMS plays a significant role in addiction treatment, particularly because it targets neurobiological processes. Addiction is characterized by permanent changes in the brain’s reward, pleasure, and motivation systems. In particular, the regions of the brain that regulate dopamine release form the basis of addictive behaviors. Deep TMS directly stimulates these deep brain structures to regulate the release of neurotransmitters such as dopamine, thereby helping to reduce addiction-related behaviors.
Traditional methods used in addiction treatment are based on medication and psychotherapy, but these approaches may not always be effective
. This is where Deep TMS comes into play as an alternative option, particularly in cases of treatment-resistant addiction. By strengthening the brain’s impulse control and self-regulation mechanisms, this treatment reduces cravings and desires for addictive substances. At the same time, by restructuring the reward circuits that develop over time in deep brain structures, it helps the individual stay away from addictive substances.
Another advantage of Deep TMS in the fight against addiction is that it is a non-invasive and painless method. The fact that it does not require surgical intervention, has minimal side effects, and allows patients to continue their daily lives uninterrupted makes this method an attractive treatment option. Furthermore, by increasing brain plasticity throughout the treatment process, it facilitates the development of new, healthy habits and helps him overcome addiction.
