If TMS hasn’t led to meaningful improvement by session 20, I carefully reassess coil position, motor threshold, and dosing, and, if tolerated, increase settings to a clearly therapeutic level. At this point, I also encourage adding psychotherapy and considering starting or adjusting medications that haven’t been tried before.

Completing the Course

There is no medical harm in completing all 36 TMS sessions to obtain a definitive answer, though practical considerations like scheduling and logistics may come into play. While a small minority of patients respond later in the course, most do not experience improvement if there has been zero change by session 20.

Reevaluating Your Diagnosis and Contributors

I revisit the diagnosis and consider contributing factors such as trauma, personality traits, and active substance use. I also coordinate closely with your primary psychiatrist, who can provide insight into your long-term patterns and past treatment responses.

What is the next step if TMS doesn't work

Next-Line Treatment Options for Resistant Depression

If TMS hasn’t led to meaningful improvement, it’s important to consider additional steps to address treatment-resistant depression and ensure a comprehensive approach.

  • Medication strategies you may not have tried, including older classes such as MAOIs.
  • Evidence-based psychotherapy, including approaches tailored to trauma or personality patterns.
  • ECT for severe, treatment-resistant depression. ECT remains the most effective acute treatment we have, with the highest remission rates across modalities.
