Researchers at Harvard Medical School and Weill Cornell Medical College have discovered that low field magnetic stimulation (LFMS) has the potential to treat depression with rapid mood-elevating effects. The two brain stimulation treatments currently used, electroconvulsive therapy (ECT) and transcranial magnetic stimulation (TMS), often have a delayed onset similar to antidepressant medications. For example, a patient may receive several weeks of regular ECT treatments before a full response is achieved. Immediate and substantial improvement in mood was observed in patients who received one 20-minute session of LFMS, with no reported side effects. This finding suggests that LFMS may provide immediate relief of depressed mood, perhaps even in emergency situations.
