What is TMS?

About TMS

Repetitive Transcranial Magnetic Stimulation (TMS) is a non-invasive technology of brain stimulation in which an electric current is induced in the brain by means of alternating magnetic fields.

It is a treatment alternative for people suffering from e.g. major depressive disorder. TMS is typically used when other depression treatments have not been effective.

This form of therapy is well tolerated and does not cause systemic side effects. It can be performed on an outpatient basis and does not require anesthesia.

TMS Treatment

Since 2008, TMS has been FDA-cleared for the treatment of patients with Major Depressive Disorder (MDD).
Controlled clinical trials using TMS in patients with MDD have shown that1

  • Approximately half of patients experienced significant improvement in depressive symptoms.
  • Approximately 1 in 3 patients experienced complete relief of symptoms after TMS therapy.

TMS is a non-invasive, drug-free treatment for major depression using magnetic pulses targeted at a specific location on the brain.

During the therapy session, the patient sits comfortably in a chair. An electromagnetic coil is placed against the patient’s head during the session. The coil stimulates the underlying brain area by generating a temporary magnetic field.
