Depression can be a devastating and unremitting problem.
Researchers of a new study published in the current issue of Biological Psychiatry report successful reduction of depressive symptoms in patients using a novel non-invasive method of vagus nerve stimulation, or VNS.
Despite the growing number of medications and neurostimulation approaches available, residual symptoms may be both distressing and disabling. Traditional vagus nerve stimulation (VNS) is a neurostimulation technique that has been used to alleviate treatment-resistant symptoms of depression. Clinical trials suggested that it produced modest benefit that emerged over long periods of time. However, it was also costly and required risky neurosurgery to implant the vagal nerve stimulators.
