Novel Treatment of Depression Shows Immediate Results
Posted: November 1st, 2014
Michael Rohan, a physicist at McLean Hospital’s Brain Imaging Center, demonstrated the low-field magnetic stimulation (LFMS) device he developed.
Individuals with major depressive disorder or bipolar disorder who receive low-field magnetic stimulation (LFMS) show immediate and substantial mood improvement, McLean Hospital researchers report in the Aug. 1 issue of Biological Psychiatry.
“LFMS is unlike any current treatment. It uses magnetic fields that are a fraction of the strength but at a higher frequency than the electromagnetic fields used in TMS [transcranial magnetic stimulation] and ECT [electroconvulsive therapy],” explained first author Harvard Medical School.
According to Rohan, although other brain stimulation treatments like ECT and TMS are often effective for the treatment of depression, they typically take longer to impact mood, and ECT is associated with side effects such as memory loss. Similarly, while antidepressant medications can be highly effective for treating depression, it can take between four to six weeks before mood changes are detected.
“Importantly, LFMS appears to have an immediate effect on mood and thus has the potential to provide relief in emergency situations,” explained Rohan, who first reported the potential use of LFMS to treat depression in a groundbreaking study in 2004. “In addition to providing quick relief from symptoms, the other exciting piece about LFMS is that no side effects have been observed.”(more…)
