How Long Does It Take for TMS to Start Working for Depression?

One of the most common questions we are asked here at Madison Avenue TMS & Psychiatry is, “How long until I see results with TMS?” The shortest answer is: The time it takes to notice results with TMS depends on each patient. Are there reasons why some people notice a change in symptoms before others? Let’s take a look.

How Long Does the TMS Treatment Process Take?

At Madison Avenue TMS & Psychiatry, we administer repetitive transcranial magnetic stimulation (TMS) as a one-course treatment over the course of nine weeks total: a six-week course of treatment, followed by a three-week taper period.

How Long Until I See Results With TMS?

Some of our patients report feeling a slight improvement in their symptoms after two weeks of treatment, while others do not report noticeable changes until weeks four or five. If it takes longer to notice symptom relief using TMS compared to someone else, this does not mean that the treatment is ineffective. Ultimately, the effects of TMS are the same: relief of depressive symptoms that are long-lasting.

Factors That May Affect Your Time to Results with TMS

Researchers are working to find trends in TMS response rates. So far, some of the possible factors include:

  • Age: Younger patients have been shown to respond better to TMS. (1)
  • Personality characteristics: People with higher persistence scores on the Temperament and Character Inventory questionnaire have been shown to respond more to TMS after two weeks of treatment, compared to patients with lower persistence scores. (2)
  • Brain activity prior to treatment: Various studies have demonstrated that brain activity prior to TMS treatment may indicate how one responds to TMS treatment. (3)
  • The level of treatment resistance: Patients who are less treatment-resistant to antidepressant medications have been shown to respond more positively to TMS. (4)
  • Whether you take an antidepressant during treatment: Some patients may experience increased benefits if receiving TMS as an augmentative treatment to their antidepressant medication. (5,6)

TMS Provides Long-Lasting Results

It can be tempting to focus on the short-term effects of any treatment. But it’s important to know that TMS makes its biggest impact with the proven long-term results it provides. A study published in the Journal of Clinical Psychiatry observed adult patients diagnosed with major depressive disorder who did not respond to antidepressant medication. All patients enrolled in the study received a single course treatment lasting six weeks. The results: 62.5 percent of patients were symptom-free and in remission even one year after their initial treatment. (7)
