TMS has emerged as a revolutionary tool in the treatment of Depression, offering hope for those who have not benefited from other therapies. A key question often posed by both patients and practitioners is: how many sessions for TMS to work most effectively? Understanding how many TMS sessions are needed is essential for setting realistic expectations and achieving the best possible outcomes.
This article addresses what the latest research says about longer TMS treatment courses and the optimal number of TMS sessions required to achieve the best therapeutic outcome, paving the way for personalized Depression management. We’ll unpack how extended sessions can make the difference between partial and full recovery, and how our office advocates for patients during the recovery process.
What Is TMS Therapy?
Transcranial Magnetic Stimulation (TMS) is an FDA-approved, non-invasive treatment for Depression that uses gentle magnetic pulses to stimulate the brain regions involved in mood regulation. Unlike medications, TMS does not circulate through the bloodstream and does not cause systemic side effects like weight gain, fatigue, or sexual dysfunction.
Typically, the TMS treatment schedule consists of five sessions per week, each lasting between 3 to 20 minutes, over 7-8 weeks. Over time, repeated stimulation strengthens neural circuits linked to mood, gradually reducing symptoms of Depression. For people with treatment-resistant Depression (TRD) (meaning they’ve tried at least two antidepressants without sufficient relief) TMS offers a highly safe and effective, evidence-based alternative.
But patients interested in this treatment are often curious regarding how many sessions for TMS to work, and that means for their long-term treatment plan.
How Many Sessions for TMS to Work? Why Session Count Matters
While some patients experience rapid improvement within the first few weeks, others need more time. Like physical therapy for the brain, TMS works through repeated, consistent sessions that gradually retrain and strengthen neural pathways.
The question of “how many sessions for TMS to work?” has been studied extensively and understanding how many TMS sessions are needed represents a critical factor for achieving lasting relief. The evidence shows that symptom improvement is cumulative, meaning patients continue to improve the longer treatment continues.
Stopping too early may reduce effectiveness, as ending treatment while symptoms are still improving risks relapse. Research also indicates that more sessions often equal better outcomes, with patients who continue beyond the minimum frequently achieving deeper, longer-lasting relief.
New Research: Extended TMS Sessions Improve Outcomes
A 2024 study published in Brain Stimulation followed 324 patients who received up to 51 sessions of TMS. Researchers analyzed patient outcomes using the PHQ-9, a widely used Depression scale used at Mid City TMS, and identified four distinct patterns of response:
- Rapid Responders (21%): Improved quickly within the first few weeks.
- Slowed Responders (49%): Improved gradually with steady gains over time.
- Extended Course Responders (23%): Continued to improve steadily well beyond 36 sessions, with significant additional benefits when treatment was prolonged.
- Non-Responders (7%): Did not show meaningful improvement.
Key Takeaways From the Brain Stimulation Study
Nearly one in four patients experienced their best results only after completing more than 36 sessions. The most significant symptom reduction was observed in patients who completed 36 sessions. Extended treatment (more than 36 sessions) showed continued improvement without signs of plateauing in antidepressant effects. The group data revealed no evidence that the antidepressant effects of TMS reached a plateau with additional treatment.
This confirms what clinicians at Mid City TMS have seen for years: some patients need extended treatment to reach full remission, and stopping at 36 sessions may prevent them from achieving their best outcome. For patients wondering how many TMS sessions are needed, this research provides valuable guidance.
The Mid City TMS Approach: 36 Sessions and Beyond
At Mid City TMS, we don’t believe in a one-size-fits-all approach when it comes to how many TMS sessions are needed. Instead, we tailor each treatment plan to the individual patient. Here’s how:
- Every patient receives at least 36 sessions, the evidence-based standard. When examining how many sessions for TMS to work, we understand that every patient has unique needs.
- Progress is carefully monitored with tools like the BDI and PHQ-9, clinical evaluations, and regular check-in follow up appointments with Dr. Bruno.
- If improvement is ongoing, treatment continues when warranted; we try not to stop care when more sessions could bring additional benefit.
- We advocate for insurance coverage. Our team handles authorizations and appeals so patients can often continue treatments beyond the usual 36 session course and are authorized by insurance.
This 36-session commitment ensures that every patient has the best possible chance of achieving full and lasting relief from Depression.
How Many TMS Sessions Are Needed: Why More Than 36 Sessions?
When understanding the ins and outs of how many sessions for TMS to work, Think of TMS like building strength at the gym. Some people regain muscle quickly, while others need more workouts to reach their goal. The same is true for the brain.
There are several reasons why additional sessions might become necessary. The brain heals at different speeds, and some patients need more time for neural circuits to adapt and strengthen. Gradual responders benefit from extended treatment, as nearly half of patients improve steadily over time and many continue progressing after session 36. Additionally, more sessions reduce the risk of relapse by helping solidify gains and lowering the chance that symptoms will return.
By ensuring every patient has access to additional sessions or maintenance TMS when needed, Mid City TMS helps maximize long-term outcomes.
