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 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 ...
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 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 treatment for seizures may include antiepileptic medications, diet and vagus nerve stimulator. Medication Any number of medications may be used to both prevent ...
Vagus nerve stimulation therapy improved the symptoms of treatment-resistant depression for nearly 500 participants in a major clinical trial.
Peripheral nerve interfaces are used for pain modulation, [7] restoration of motor function following spinal cord injury or stroke, [8] treatment of epilepsy by electrical stimulation of the vagus nerve, [9] nerve stimulation to control micturition, occipital nerve stimulation for chronic migraines and to interface with neuroprosthetics.
Another method to treat epilepsy is vagus nerve stimulation. [3] Although the corpus callosum is the largest white matter tract connecting the hemispheres, some limited interhemispheric communication is still possible via the anterior and posterior commissures. [4]
