Psychiatry Electroconvulsive therapy
in which a pacemaker-like device stimulates the vagus nerve. See Electroconvulsive therapy.

vagus nerve stimulation

A treatment for seizures and treatment-resistant depression in which a generator sends electrical impulses along the left vagus nerve. The impulse generator is typically inserted under the clavicle on the left side of the chest during a brief surgical procedure. The device is set to generate electrical impulses of appropriate amplitude, frequency, and pulse width to control a patient's symptoms.

Muscle stimulation devices market will witness the benefits of clinical trials being conducted by healthcare universities such as the Ohio State University for curtailing the motor skills recovery time for stroke patients through vagus nerve stimulation (VNS).
Electrical stimulation to the right areas may stop inflammation.7 Activation of vagus nerve modulates leukocyte cytokine production and alleviates experimental shock and autoimmune disease, recent data have suggested that vagus nerve stimulation can improve symptoms in human rheumatoid arthritis.8 Development of a Microchannel Electrode Array (DCEA) capable of interfacing nerve fascicles as small as 50-300 micrometre.9 There appears to be the potential for an ultrasound-based neural interface system for advancing future bioelectronics-based therapies.10 The main claimed advantages of the new devices are integration of multiple steps in complex analytical procedures, diversity of application, sub-microliter consumption of reagents, sample and portability.11
Other types of treatment include brain surgery, another type of surgery called vagus nerve stimulation, and a special diet called the ketogenic diet which is sometimes used for children.
Cervical vagus nerve stimulation (VNS) has been approved for the treatment of refractory epilepsy and depression in the Unites States.
Vagus nerve stimulation (VNS) is an invasive technique consisting of inserting a pulse generator under the skin of the upper chest, which sends signals through the electrodes of the lead to the brain by way of the left vagus nerve (8,9).
On the other hand, low vagus nerve activity has been related to poor outcome, and vagus nerve stimulation with a good outcome in other conditions such as irritable bowel syndrome, metabolic syndrome, diabetes, sepsis, pancreatitis, depression, pain, and epilepsy [23-29].
Vagus nerve stimulation, or VNS, is FDA-approved for patients with chronic moderate-to-severe MDD who have not responded to repeated courses of antidepressant medication.
