Bipolar disorder or manic depression patients, most of the times, find medications that simply do not work. They are treatment-resistant. The vagus nerve stimulator has proved as a better treatment device for maniac depression. A patient, Lauri Ticas, who finally opted for the device, said, depression used to control me, now I control the depression. The vagus nerve stimulator has been available for eight years for the treatment of epilepsy. The Food and Drug Administration recommended its use for chronic or recurrent treatment-resistant depression and bipolar disorder. VNS may be an option for patients who are unable to take any of the psychiatric medications due to bad side effects. Cyberonics, the manufacturer of the vagus nerve stimulator, says that the cost of device $15,000 and with implantation, cost goes to $25,000.
