The energy is delivered by a flat, round battery, about the size of a silver dollar, which is surgically implanted in the chest wall. The therapy is designed to prevent seizures by sending regular small pulses of electrical energy to the brain via the vagus nerve, a large nerve in the neck. It is currently approved for use in adults and children over the age of 12 who have partial seizures that resist control by other methods. Vagus nerve stimulation (VNS) therapy for epilepsy.Vagus Nerve Stimulation therapy is another form of treatment that may be tried when medications fail to stop seizures.Vagus nerve stimulation inhibits cytokine production and attenuates disease severity in rheumatoid arthritis.

Fear management: The vagus nerve sends information from the gut to the brain, which is linked to dealing with stress, anxiety, and fear – hence the saying, “gut feeling.” These signals help a person to recover from stressful and scary situations.In some cases, excessive vagus nerve activity can cause loss of consciousness and organ damage. Lowering the heart rate and blood pressure: If the vagus nerve is overactive, it can lead to the heart being unable to pump enough blood around the body.Decreasing inflammation: The vagus nerve sends an anti-inflammatory signal to other parts of the body.With deep breaths, a person feels more relaxed. Relaxation with deep breathing: The vagus nerve communicates with the diaphragm.Communication between the brain and the gut: The vagus nerve delivers information from the gut to the brain.As a result, the vagus nerve also helps with defecation, urination, and sexual arousal. The parasympathetic side, which the vagus nerve is heavily involved in, decreases alertness, blood pressure, and heart rate, and helps with calmness, relaxation, and digestion. The sympathetic side increases alertness, energy, blood pressure, heart rate, and breathing rate. The nervous system can be divided into two areas: sympathetic and parasympathetic. One of these is balancing the nervous system. Its functions can be broken down even further into seven categories.
