VNS is now the most widely used non-pharmacological treatment modality for the management of drug resistant epilepsy and is the only FDA approved neurostimulation treatment strategy for patients who are not eligible for Epilepsy Surgery .
A vagus nerve stimulator consists of two electrodes embedded in a silastic helix that is wrapped around the cervical vagus nerve . The stimulator is always implanted on the left vagus nerve in order to reduce the likelihood of adverse cardiac effects .

Gamma Knife to treat Epilepsy
Radiosurgery is a surgical procedure where narrow beams of radiation are targeted to a precisely defined volume of tissue within the brain. This highly focused and destructive dose of radiation is given in a single session and avoids potentially harmful radiation to surrounding brain structures. Professor Lars Leksell, a Swedish Neurosurgeon, first developed stereotactic devices (used to guide the gamma rays) as well as the very concept of Radiosurgery.

Vagal Nerve Stimultaion for epilepsy
Vagus nerve stimulation therapy is another form of treatment that should be tried when medications fail to stop seizures. It is currently approved for use in adults and children over the age of 12 who have partial seizures that resist control by other methods. The therapy is designed to prevent seizures by sending regular small pulses of electrical energy to the brain via the vagus nerve, a large nerve in the neck.

Treatment Options for Epilepsy patients
Radiosurgery differs from conventional radiation therapy in several respects. With standard external beam radiation therapy techniques, tumors and much or all of the surrounding brain are treated to the same dose of radiation. The radiation dose is given in small increments over several weeks to allow normal brain tissue to recover from its effect, while tumor tissue is less likely to recover. Ultimately, the brain can absorb a maximal dose of radiation, beyond which no further treatment is advisable. There is increasing evidence that over long periods of time, high doses of radiation are harmful to normally functioning brain. The technique of Gamma Knife radiosurgery treats only the abnormal tissue, in a single session, without significant radiation to adjacent brain. Professor Leksell’s concept has proved to be a true advance in the treatment of intracranial disease.
