Types of TMS

Transcranial magnetic stimulation (TMS) has emerged as a groundbreaking treatment option for depression, obsessive-compulsive disorder, and other psychiatric conditions, offering hope to patients who haven’t found success with traditional therapies. As this innovative technology continues to evolve, several distinct types of TMS have been developed, each with its unique approach to brain stimulation. From traditional methods to cutting-edge navigated systems, understanding the different kinds of TMS available today can help patients make more informed decisions about their treatment options. This comprehensive guide will explore the current TMS techniques, starting from traditional approaches and ending with the most advanced therapies offered by Mindful TMS Neurocare Center in Chicago.

Repetitive Transcranial Magnetic Stimulation (rTMS)

How Does It Work?

rTMS uses electromagnetic pulses to stimulate specific areas of the brain associated with mood regulation. During treatment, an electromagnetic coil is placed against the scalp, typically near the left dorsolateral prefrontal cortex (DLPFC) — an area known to be underactive in people with depression and other mental health conditions. When activated, the coil generates magnetic pulses that pass painlessly through the skull and into the brain tissue. It creates tiny electrical currents that stimulate nerve cells in the targeted region.

The “repetitive” nature of rTMS refers to the consistent rhythm of these pulses, typically delivered at frequencies between 1 and 20 Hz. When administered over multiple sessions, they can help normalize brain activity patterns, improve neural connectivity, and enhance the release of neurotransmitters, ultimately leading to symptom improvement. Traditional rTMS procedures usually last about 20-40 minutes and are provided five days a week for 4-6 weeks.

Typical Applications

Repetitive TMS is the most widely known and FDA-approved for treating major depressive disorder (MDD), particularly in cases where medication has proven ineffective. However, its applications extend beyond depression. The FDA has also approved rTMS for treating obsessive-compulsive disorder (OCD) and smoking cessation. Additionally, many TMS practitioners use rTMS to address anxiety, PTSD, chronic pain, and specific symptoms of autism spectrum disorders (ASD). This technique may also help patients with migraine headaches and tinnitus. In recent years, there’s been growing evidence supporting its use in cognitive enhancement and rehabilitation following stroke or traumatic brain injury (TBI). However, it’s important to note that while some of these applications are well-established, others are still being studied through clinical trials to determine their full therapeutic potential.

Deep Transcranial Magnetic Stimulation (dTMS)

How Does It Work?

Deep TMS differs from traditional rTMS through its innovative H-coil design, which enables magnetic stimulation to reach broader and deeper brain regions. While standard TMS penetrates approximately 0.7 cm beneath the skull, dTMS can effectively stimulate areas up to 4 cm deep. The H-coil’s unique design creates a more comprehensive magnetic field that targets larger brain volumes, allowing for more extensive neural network activation.

The H-coil is housed within a cushioned helmet that fits comfortably over the patient’s head, delivering stimulation in a more distributed manner. This comprehensive approach can be particularly beneficial when treating complex conditions that involve multiple brain regions.

Typical Applications

Deep TMS has received FDA approval for several significant applications, including MDD, OCD, anxious depression, and late-life depression. The technology has shown notable success in treating OCD symptoms, targeting the anterior cingulate cortex and medial prefrontal cortex – deeper brain regions that are crucial in OCD pathology. The FDA has also cleared dTMS for smoking cessation, where it targets reward pathways. dTMS’s ability to reach deeper brain regions is particularly effective for patients who haven’t responded well to traditional rTMS. Currently, researchers are exploring its potential applications in treating other conditions, such as bipolar disorder, PTSD, and various forms of addiction.

Theta Burst Stimulation (TBS)

How Does It Work?

TBS represents a more time-efficient protocol of TMS therapy that mimics the brain’s natural theta wave patterns. Unlike traditional rTMS, which delivers pulses at a steady rhythm, TBS generates bursts of three pulses at 50 Hz, repeated at 5 Hz intervals. This pattern closely resembles the brain’s natural theta rhythm of neural firing.

TBS can be performed in two main ways: intermittent TBS (iTBS), which includes short periods of stimulation followed by breaks, or continuous TBS (cTBS). The theta burst pattern is powerful because it more closely matches the brain’s learning and memory formation patterns, potentially leading to faster and more robust neuroplastic changes. This means that TBS can achieve similar or superior results to traditional TMS in much shorter sessions — typically just 3-9 minutes compared to the standard 20-40-minute sessions of conventional TMS.

Typical Applications

In 2018, TBS received FDA approval for treating MDD, and clinical studies have demonstrated comparable or superior effectiveness to standard TMS treatment. Its efficiency makes TBS particularly attractive for patients with busy schedules or those who find longer sessions challenging. Beyond treatment-resistant depression, researchers are investigating TBS applications for various neurological and psychiatric conditions, including anxiety disorders, PTSD, and chronic pain. The protocol has shown promising results in cognitive enhancement and rehabilitation settings, with some studies suggesting it may be particularly effective for improving working memory and attention.

Navigated Transcranial Magnetic Stimulation (nTMS)

How Does It Work?

Navigated TMS is the most advanced and precise form of TMS therapy, integrating magnetic resonance imaging (MRI) technology with real-time motion tracking. Unlike traditional TMS methods, which rely on external anatomical landmarks and approximate measurements, nTMS uses each patient’s MRI to create a detailed 3D map of their brain structure. This sophisticated system employs infrared cameras to track the head position and the TMS coil in real-time, ensuring precise targeting accuracy within millimeters.

The navigation system provides immediate visual feedback to the operator, displaying the exact location and strength of stimulation on the patient’s brain map, much like a GPS. This level of precision allows clinicians to consistently target specific brain regions across multiple sessions with unprecedented accuracy while enabling them to make real-time adjustments based on patient movement. At Mindful TMS Neurocare Center in Chicago, the only provider of nTMS in the area, this technology ensures that each pulse is delivered precisely where intended, maximizing treatment effectiveness while minimizing stimulation of the unintended regions.

Typical Applications

Navigated TMS follows the same FDA-approved applications as traditional TMS, primarily focusing on MDD and OCD. This innovative technique may offer many advantages for treating depression and other conditions, as it ensures consistent stimulation of the exact intended location across all treatment sessions.

Magnetic e-Resonance Therapy (MeRT)

How Does It Work?

MeRT builds on the principles of traditional TMS while incorporating advanced neurophysiological mapping and tailored treatment protocols. The process begins with an electroencephalogram (EEG) and, in some cases, a quantitative EEG (qEEG) to assess the brain’s electrical activity and identify areas with dysregulated or asymmetrical patterns. Using this data, the MeRT practitioner creates a customized treatment plan to stimulate specific brain regions with precise magnetic pulses.

Unlike standard repetitive TMS (rTMS), which typically targets one area with uniform parameters, MeRT adjusts frequency, intensity, and stimulation location based on each patient’s unique brainwave activity. The therapy aims to restore optimal neural function by realigning the brain’s natural rhythms and improving connectivity. Sessions typically last 30-45 minutes and are conducted over several weeks.

Typical Applications

MeRT is commonly used to treat a wide range of conditions, including depression, PTSD, TBI, and ASD. This tailored approach is particularly beneficial for individuals who have not responded to traditional TMS or other treatments. Additionally, some clinics have explored its potential for cognitive enhancement and improving symptoms of neurodegenerative disorders like Alzheimer’s disease, although these applications are still under investigation.
