TMS Therapy: A Patient's Guide
Transcranial magnetic stimulation (TMS) is a non-invasive treatment that uses magnetic pulses to stimulate the brain areas involved in mood. It is FDA-cleared for depression that has not improved with medication, and for a small number of other conditions. You are awake for each session and can go straight back to your day.
This guide answers the questions patients actually ask, in the order they usually ask them. Every article cites its sources, and every figure in it was checked against the study, label or insurance policy it comes from.
