Summary: Researchers modified current transcranial magnetic stimulation technology to improve its effectiveness for treating depression. The new system, Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT), targeted the subregion between the dorsolateral prefrontal cortex and subgenual cingulate in patients suffering from depression. The treatment delivered rapid relief from depression symptoms for 90% of the test subjects. For 60% of recipients, the effects lasted for more than one-month post-treatment.
A new form of magnetic brain stimulation rapidly relieved symptoms of severe depression in 90% of participants in a small study conducted by researchers at the Stanford University School of Medicine.
The researchers are conducting a larger, double-blinded trial in which half the participants are receiving fake treatment. The researchers are optimistic the second trial will prove to be similarly effective in treating people whose condition hasn’t improved with medication, talk therapy or other forms of electromagnetic stimulation.
The treatment is called Stanford Accelerated Intelligent Neuromodulation Therapy, or SAINT. It is a form of transcranial magnetic stimulation, which is approved by the Food and Drug Administration for treatment of depression. The researchers reported that the therapy improves on current FDA-approved protocols by increasing the number of magnetic pulses, speeding up the pace of the treatment and targeting the pulses according to each individual’s neurocircuitry.
Before undergoing the therapy, all 21 study participants were severely depressed, according to several diagnostic tests for depression. Afterward, 19 of them scored within the nondepressed range. Although all of the participants had suicidal thoughts before the therapy, none of them reported having suicidal thoughts after treatment. All 21 participants had previously not experienced improvements with medications, FDA-approved transcranial magnetic stimulation or electroconvulsive therapy.
The only side effects of the new therapy were fatigue and some discomfort during treatment, the study reported. The results was published online April 6 in the American Journal of Psychiatry.
“There’s never been a therapy for treatment-resistant depression that’s broken 55% remission rates in open-label testing,” said Nolan Williams, MD, assistant professor of psychiatry and behavioral sciences and a senior author of the study. “Electroconvulsive therapy is thought to be the gold standard, but it has only an average 48% remission rate in treatment-resistant depression. No one expected these kinds of results.”
