Some research showed that transcranial magnetic stimulation improved depression symptoms, while in other studies it didn't seem to help. If transcranial magnetic stimulation works for you, your depression symptoms may improve or go away completely. Symptom relief may take a few weeks of treatment.

Transcranial magnetic stimulation may be less likely to work if:

  • Your mental illness causes detachment from reality (psychosis)
  • Your depression has lasted for four or more years
  • Electroconvulsive therapy (ECT) has not worked to improve depression symptoms

It's not yet known if transcranial magnetic stimulation 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 transcranial magnetic stimulation may improve as researchers learn more about techniques, the number of stimulations required and the best sites on the brain to stimulate.
