A possible early predictor of successful TMS therapy for major depression - Video

A new study from UCLA Health researchers demonstrates that a novel treatment is effective in most patients with major depressive symptoms even after multiple failed courses of antidepressant medication. The treatment, repetitive transcranial magnetic stimulation (rTMS), may work even more rapidly than past findings have suggested, starting to alleviate symptoms as quickly as one week.

Researchers from the Neuromodulation Division of UCLA’s Semel Institute analyzed the outcomes of hundreds of patients treated at UCLA Health from 2009 to 2022 with rTMS therapy, which uses magnetic fields to effectively “rewire” the brain’s circuitry. The new study published this week in Psychiatry Research found that 54% of patients exhibited clinical response (at least a 50% improvement) in mood symptoms when examined using multiple depression rating scales.

Using multiple scales rather than one allows us to better detect and characterize the effectiveness of rTMS treatment for the many different faces of depression,” Leuchter said.

Additionally, early improvements reported within five or 10 treatments were found to be significant predictors of how well a patient will respond throughout the course of treatment. Leuchter said this could help doctors determine whether or when to modify their clinical approach for a patient.
