Transcranial Magnetic Stimulation (TMS) FAQ

What is TMS?

Transcranial Magnetic Stimulation (TMS) is a noninvasive form of brain stimulation. FDA-approved in 2008, it uses magnetic fields to stimulate nerve cells in the brain, primarily to improve symptoms of depression and anxiety. TMS therapy is suitable for those with Major Depressive Disorder (MDD) who haven't found relief through antidepressants or therapy. It can be used alone or with medications​​.

​

Typical TMS Series

A typical course includes 5 treatments per week for 6 weeks, plus a TMS taper, totaling 36 treatments. Each session lasts 20-40 minutes, targeting the dorsolateral prefrontal cortex (DLPFC). Patients remain awake and can resume daily activities immediately after​​.

​

TMS Induction

The first appointment involves brain mapping, motor threshold determination, and an initial treatment. Brain mapping locates the DLPFC, and motor threshold determination sets the magnetic stimulation dose​​.

​

Theta Burst Stimulation

Intermittent Theta burst stimulation (iTBS) is a faster TMS form, completing in 3-5 minutes compared to the conventional 20-40 minute sessions​​.

​

Is TMS Effective?

TMS effectiveness varies. It's less likely to be effective for patients with long-term illness or those who have exhausted other treatment options. However, each case is individual​​.

​

What are the Side Effects of TMS ?

TMS side effects can include minor headaches, scalp pain, and mild muscle twitching during treatment. These typically improve within a week​​.

​

What is Duration of Benefits after TMS treatment?

TMS benefits can last up to a year after a successful course, but maintenance therapy may be necessary​​.

​

Insurance Coverage

Medicare and many private insurances cover TMS for Major Depressive Disorder, but not all policies cover Theta Burst Stimulation. Coverage typically requires a recent failed psychotherapy trial and multiple medication trials​​.
