AWAY DEPRESSION [ back
to What's New ]
Approximately 1,000,000 people suffer from "intractible"
depression, about 15% of which will commit suicide. These
are people who have not responded to medication, psychotherapy
or hospitalization. In March 2000, it was announced by University
of Texas, Southwestern Medical Center of Dallas, and 3 sister
research institutions that promising results for treating
such patients had been reached through surgical implantation
of a small pace-maker like device in the chest which emits
a mild current to the vagus nerve every 5 minutes, 24 hours
a day. According to device manufacturer Cyberonics,
Inc. of Houston, the total cost of the device, surgery and
follow-up is $15,000 and an application for FDA approval of
the device in now pending. Although the mood enhancing effect
of vagus nerve stimulation is not understood, and was discovered
accidentally, it appears to work dramatic improvement. Out
of 30 patients hospitalized recurrently for chronic severe
depression, 17 are doing much better and have been able to
stay out of the hospital. 200 new patients will be tested
later this year at the Medical University of South Carolina
at Charleston.
