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.
Vagus nerve stimulation (VNS) involves implanting a pacemaker-like generator below the skin in the chest area that intermittently sends electrical impulses to the left vagus nerve in the neck. The impulses are mediated to the brain by the vagus nerve and thereby help to inhibit electrical disturbances that cause seizures.
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 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.

Joseph signed on and began using a non-invasive VNS device that delivers electrical stimulation to the vagus nerve through the ear, twice a day for 10 minutes at a time.
Brain stimulation has potentials to treat some disorders such as epilepsy. In this method, scheduled stimulation is applied to specific cortical or subcortical targets. There are available commercial devices [5] that can deliver an electrical pulse at scheduled time intervals. Scheduled stimulation is hypothesized to alter the intrinsic ...
Vagus nerve stimulation therapy improved the symptoms of treatment-resistant depression for nearly 500 participants in a major clinical trial.
