Hear from a physician
"I would consider VNS Therapy under two different but related circumstances. First, for individuals who have had several different individual treatment trials, different medications or combinations. Perhaps three or four, or even more, of those kinds of treatments and the individual has not had an adequate acute response, that is they have not gotten rid of their symptoms adequately. So those individuals would clearly be candidates for VNS Therapy.

"In those individuals who had a good initial response but are unable to sustain it over time, even though they are taking the treatments, they are also good candidates for VNS Therapy."

—Dr. A. John Rush, Vice Chair, Department of Clinical Sciences Professor, Department of Psychiatry University of Texas Southwestern Medical Center at Dallas
