While powerful transcanial magnetic stimulation (TMS) of the frontal lobe of the brain can alleviate symptoms of depression, those receiving the treatment did not report effects on sleep or arousal commonly seen with antidepressant medications, researchers have found.
“People’s sleep gets better as their depression improves, but the treatment doesn’t itself cause sedation or insomnia.” said Dr. Peter B. Rosenquist, Vice Chair of the Department of Psychiatry and Health Behavior at the Medical College of Georgia at Georgia Health Sciences University.
The finding resulted from a secondary analysis of a study of 301 patients at 23 sites comparing the anti-depressive effects of the Neuronetics Transcranial Magnetic Stimulation Therapy System to placebo treatment in patients resistant to antidepressant medications. These initial findings, published in the journal Biological Psychiatry in 2007, were the primary evidence in the FDA’s approval of TMS for depression.
