If you’ve been exploring treatment options for depression, OCD, or other psychiatric conditions, you may have come across Transcranial Magnetic Stimulation (TMS). One of the most important advancements in this field is Deep TMS (dTMS).
In my practice, I often meet patients who have already tried medications, therapy, ECT (electroconvulsive therapy), or even standard TMS, but still feel stuck. Understanding how Deep TMS works—and how it differs from other forms of TMS—can help clarify whether this approach may be right for you.
What Is Deep TMS?
Deep TMS is a non-invasive treatment that uses magnetic stimulation to activate areas of the brain involved in mood, anxiety, and behavior.
What makes it different is how it reaches the brain.
Instead of focusing only on surface regions, Deep TMS allows us to stimulate deeper and broader brain circuits—areas often involved in more complex or treatment-resistant conditions.
How Deep TMS Differs from Standard TMS
Traditional TMS uses a figure-8 coil, which delivers focused stimulation to more superficial brain regions—typically about 1.5 cm in depth.
Deep TMS uses an H-coil, designed to reach approximately 3–4 cm in depth, while also engaging a wider network of brain regions.
This allows us to access not just isolated areas, but circuits involved in emotional regulation, habits, and motivation.
What Does “H-Coil” Mean?
The “H” in H-coil stands for Hesed (חסד), meaning kindness or compassion. The intention behind this technology is to expand access to treatment by reaching deeper brain structures safely and effectively.
Why This Matters Clinically
Many psychiatric conditions involve brain networks, not just a single region.
With Deep TMS, we can more effectively engage circuits involved in:
- Mood regulation
- Compulsivity and habit patterns
- Reward and motivation
This is particularly relevant in:
- Depression
- OCD
- Anxiety and chronic rumination
- Trauma-related conditions
- Addiction
One Technology, Multiple Protocols
Deep TMS is not a single, uniform treatment. It includes multiple coils and protocols, each designed for different brain circuits.
For example:
- H1 coil → Depression
- H7 coil → OCD
This allows for a more personalized approach, based on each patient’s symptom profile.
Beyond Standard Indications
Because of its ability to reach deeper and broader areas, Deep TMS also allows for thoughtful off-label use in clinical practice.
This may include targeting:
- Persistent rumination
- Anxious preoccupation
- Trauma-related dysregulation
- Complex or mixed presentations
Often, these are situations where prior treatments did not fully help because the relevant circuits were not sufficiently engaged.
Individualized Treatment Matters
Deep TMS is not about one protocol for everyone.
What matters most is:
- Careful evaluation
- Choosing the right protocol
- Adjusting treatment based on response
In my practice, TMS is always part of a thoughtful, individualized treatment plan.
Final Thoughts
Deep TMS allows us to approach treatment with greater precision—focusing on which brain circuits need support, especially in patients who have not responded to traditional options.
