Transcranial Magnetic Stimulation


Southern Illinois Associates, LLC

What is TMS?

TMS Therapy is a Depression Therapy Covered by Insurance.

Transcranial magnetic stimulation (TMS) is a breakthrough treatment for depression, which is a non-drug, noninvasive, outpatient procedure performed right in our office.

TMS uses targeted magnetic pulses (similar to those in an MRI machine) to electrically stimulate a specific area of the brain known to be underactive in depression.
This area, the left prefrontal cortex, lies near the surface of the brain, but connects to a deeper area of the brain known as the limbic system, which regulates mood.

By stimulating this area of the brain over several weeks, the nerve cells are activated and eventually they resume sending normal electrochemical signals, brain function returns, and depressive symptoms resolve.
