If TMS works for you, your depression symptoms may improve or go away completely. Symptom relief may take a few weeks of treatment.

TMS may be less likely to work if:

  • Your mental illness causes detachment from reality (psychosis)
  • Your depression has lasted for several years
  • Electroconvulsive therapy (ECT) hasn't worked to improve depression symptoms

It's not yet known if TMS can be used to treat depression for the long term, or whether you can have periodic maintenance treatments to prevent depression symptoms from returning. The effectiveness of TMS may improve as researchers learn more about techniques, the number of stimulations required and the best sites on the brain to stimulate.
