George pioneered an rTMS treatment that was approved by the federal Food and Drug Administration for depression in 2008. He says the new rTMS approach could be a game changer because it’s both more precise and faster. He points to other similarly sized trials for depression treatments like ketamine, a version of which is now FDA-approved. Mark George, a psychiatrist and neurologist at the Medical University of South Carolina, agrees. They'd originally planned to recruit a much larger sample, but the interim analysis was definitive.” “Often, a clinical trial will be terminated early because the treatment is so effective that it would be unethical to continue giving people placebo,” said Siddiqi. Siddiqi also said the study’s small sample size, which is only 29 patients, is not cause for concern. “This study not only showed some of the best remission rates we've ever seen in depression,” said Shan Siddiqi, a Harvard psychiatrist not connected to the study, “but also managed to do that in people who had already failed multiple other treatments.” Stanford’s new delivery system may even outperform electroconvulsive therapy, which is the most popular form of brain stimulation for depression, but it requires both general anesthesia and a full medical team. The most common complaint was a light headache. Patients did not report any serious side effects. This is compared to about 13% of people who received the placebo treatment. Almost 80% of patients crossed into remission - meaning they were symptom-free within days. All of this holds true in the new treatment - it just works faster.Ī recent randomized control trial, published in The American Journal of Psychiatry, shows astounding results are possible in five days or less. As a result, people feel less depressed and more in control. That’s the basic premise of rTMS: Electrical impulses are used to balance out erratic brain activity. Williams says pumping up the prefrontal cortex helps turn down other areas of the brain that stimulate fear and anxiety. “We send a signal for the system to not only turn on, but to stay on and remember to stay on.” “It’s an area thought to be underactive in depression,” said Nolan Williams, a psychiatrist and rTMS researcher at Stanford. The electrical current is directed at the prefrontal cortex, which is the part of the brain that plans, dreams and controls our emotions. She says it felt like a woodpecker tapped on her skull every 15 seconds. (Steve Fisch)Ī coil on top of Emma’s head created a magnetic field that sent electric pulses through her skull to tickle the surface of her brain. Nolan Williams demonstrates the magnetic brain stimulation therapy he and his colleagues developed, on Deirdre Lehman, a participant in a previous study of the treatment. The remedy was a new type of repetitive transcranial magnetic stimulation (rTMS) called "Stanford neuromodulation therapy." By adding imaging technology to the treatment and upping the dose of rTMS, scientists have developed an approach that’s more effective and works more than eight times faster than the current approved treatment. I'm yelling, you know, ‘Did you see those lights?’ And while I rode home that first night I just looked out the window and I enjoyed the ride.” Even when her partner picked her up to drive home, she stayed relaxed. Then for 10 hours a day for five consecutive days, Emma sat in a chair while a magnetic field stimulated her brain.Īt the end of the first day, an unfamiliar calm settled over Emma. When she arrived, scientists took an MRI scan to determine the best possible location to deliver electrical pulses to her brain. Three years ago, Emma’s psychiatrist urged her to enroll in a study at Stanford University School of Medicine designed for people who had run out of options.
