Many individuals undergoing transcranial magnetic stimulation (TMS) therapy wonder, “What is the difference between rTMS and dTMS?” To understand this difference, it is important to first know what NeuroStar TMS therapy is. NeuroStar TMS is a non-invasive, advanced treatment for major depressive disorder (MDD). It works by transmitting magnetic pulses through the scalp, helping to balance neurotransmitters and restore function in the brain regions responsible for mood regulation.
NeuroStar TMS has been shown to be effective in managing depression, particularly for patients who have not had success with other methods such as antidepressants. If medication has failed to provide relief or has led to systemic side effects, NeuroStar TMS offers a safe and FDA-cleared alternative for managing depression. There are two main types of TMS therapy: repetitive transcranial magnetic stimulation (rTMS) and deep transcranial magnetic stimulation (dTMS).
While both rTMS and dTMS utilize the same foundational NeuroStar TMS technology, the difference lies in their distinct brain stimulation methods.
rTMS delivers magnetic pulses in a repeated sequence to stimulate neural activity in the brain. It is considered a more standard type of TMS therapy, as it was the first commercially available type. It is FDA-cleared to treat MDD and migraine headaches.
dTMS uses magnetic pulses that can penetrate deeper into the brain to target more complex brain structures directly. It is FDA-cleared to treat MDD and obsessive-compulsive disorder (as an adjunct treatment) and as an adjunct treatment for smoking cessation.
Standard rTMS and dTMS therapy use magnetic coils to deliver magnetic pulses through the scalp. These pulses do not emit radiation and are considered safe for most individuals. While rTMS and dTMS share similarities, the technology used to administer these treatments has important differences.
Standard rTMS involves placing figure-eight coils directly on the scalp to stimulate outer regions of the brain, such as the prefrontal cortex, which regulates emotions and judgment. The repetitive magnetic pulses applied to these areas can indirectly reach deeper brain regions by stimulating connected surface structures.
During an rTMS session, patients may experience a warm sensation, tapping, or a tingling sensation at the coil placement site. Some individuals may also feel scalp discomfort. However, these side effects are typically mild and resolve quickly, often decreasing with subsequent sessions.
dTMS uses H-shaped coils within a specialized helmet. The helmet remains in place throughout the session and enables stimulation of broader and deeper brain areas.
Determining the most appropriate treatment for you depends on your medical history, specific needs, and treatment goals. Understanding the variations between rTMS and dTMS can help guide your decision. Standard rTMS is more precise, delivering magnetic pulses to specific brain areas.
In contrast, dTMS stimulates a broader range of brain structures. Due to its curated technology, dTMS generally has a higher response and remission rate. This is because several parts of the brain are often involved in mood control, so accessing more structures and reaching those in deeper areas can result in greater treatment success.
The best way to know which type of NeuroStar TMS treatment is right for you is to schedule an initial consultation with our dedicated team. During your visit, one of our care providers will meet with you to discuss your medical history and identify what type of treatment may be most beneficial for you. A personalized health care plan will then be developed.
Factors we consider when deciding between rTMS and dTMS include depth of stimulation, efficacy, and potential side effects.
