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.”

National Depression Screening Day has been taking place since 1991 and is designed to screen those who may be suffering from depression but not know it. Participants fill out an anonymous questionnaire and, depending on their answers, are referred to mental health professionals for follow-up.

The screenings are given at colleges, workplaces, community-based organizations and military installations and will be available on line at the organization’s special web site, www.HelpYourselfHelpOthers.org. The website also lists local sites where screenings will be given.

A study done in 2009 showed that depression screenings are effective in connecting at-risk individuals with treatment. It showed that 55 percent of those who completed the screening online and who agreed to take part in a follow-up survey sought depression treatment within three months.

While McLean has held screening events in the past, this is the first time the hospital will be co-sponsoring the national event and will publicizing it via social media, including Facebook and Twitter.

The questionnaire allows individuals to screen themselves, in an anonymous way, for mood and anxiety disorders, eating disorders and alcohol use disorders. The online screenings provide an assessment of the user’s mental health, information on whether the user’s results are consistent with a mental health disorder, an overview of signs and symptoms of treatable disorders and help getting access to local treatment options.

More than 700 colleges and over 300 community-based organizations participate, resulting in more than 120,000 screenings each year.

Joan Camprodon, MD, MPH, PhD (Class of 2012), demonstrates the use of TMS on Amanda Arulpragasam, MGH Research Assistant

For patients suffering from depression, the Massachusetts General Hospital Department of Psychiatry now offers another treatment option – a new clinic based in Charlestown that uses transcranial magnetic stimulation (TMS). The clinic is part of a broader effort that includes a research enterprise program, both led by Joan Camprodon, MD, MPH, PhD, (Class of 2012) director of the Laboratory for Neuropsychiatry and Neuromodulation at Mass General. Dr. Camprodon’s team aims to understand how the brain’s structure and function affect disease and how interventions such as TMS can change the mechanisms that contribute to disease.

During a TMS procedure, focused magnetic impulses are directed to the brain. The electrical currents produced stimulate nerve cells involved in mood regulation that may be underactive in diseases such as depression. By restoring the equilibrium, TMS helps reset this imbalance of chemicals. from a diseased brain to a healthy one.
