Vagus nerve stimulation (VNS) is a medical treatment that involves delivering electrical impulses to the vagus nerve. It is used as an add-on treatment for certain types of intractable epilepsy , cluster headaches, treatment-resistant depression and stroke rehabilitation.
The patient is able to record when they are having symptoms with the device to see if their symptoms are correlating with seizures. [1] The use of responsive stimulation has found to be effective for seizure reduction. Some patients are able to achieve complete seizure freedom with responsive and non-responsive neurostimulation. [10]
The impulses are mediated to the brain by the vagus nerve and thereby help to inhibit electrical disturbances that cause seizures. The antiepileptic effect of vagus nerve stimulation increases over several months: after two years around half of VNS patients experience a reduction of their seizures by at least 50% [51] [52] and after 10 years ...

Peripheral nerve stimulation (PNS, which refers to simulation of nerves beyond the spine or brain, and may be considered to include ...
The vagus nerve stimulator is a device that can be implanted into patients with epilepsy, especially that which originates from a specific part of the brain. However, both of these treatment options can cause severe adverse effects. Additionally, while seizure frequency typically decreases, they often do not stop entirely. [40] [41]
The vagus nerve stimulator (VNS) is surgically implanted in the chest, and delivers programmed electrical stimulation to the vagus nerve in the neck. [38] The responsive neurostimulation device is implanted in the skull, monitors electrical brain activity for seizures, and responds to seizures with programmed electrical stimulation to one or ...
