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 use of neurostimulation to treat epileptic seizures is only recommended in those who have failed multiple medications for the treatment of their seizures. The NeuroPace RNS system was approved for use by the FDA in 2013 and is the only medical device for epilepsy that uses responsive neurostimulation. [ 1 ]
Vagus nerve stimulation can have side effects such as hoarse voice, pain in the throat, or change in voice. [1] In responsive neurostimulation (RNS), an electric generator device is placed in the skull to directly monitor brain activity and stop seizures via electrical stimulation. Electrical stimulations do not cause any pain or other reaction ...
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 ...
The increased need for drugs to treat PTE led to trials with antiepileptics; these early trials suggested that the drugs could prevent epileptogenesis (the development of epilepsy). [19] It was still thought that antiepileptic drugs could prevent epileptogeneis in the 1970s; [ 27 ] in 1973, 60% of physicians surveyed used them to prevent PTE ...
