Input nerve fibres transmit sensations and electrical feedback from the heart, lung, stomach and upper bowel to the brain. Output nerve fibres control muscles responsible for swallowing, coughing and voice sounds. The vagus nerve is one of the cranial nerves, meaning a nerve that is connected directly to the brain. Assessment by a paediatric neurologist experienced in comprehensive epilepsy management, including surgery, and VNS therapy is a prerequisite. VNS therapy is generally considered for children with epilepsy which significantly affects the life of the child and family, is not adequately controlled by antiseizure medication, and is not treatable with surgery. Who is suitable for vagus nerve stimulation? VNS therapy works differently to antiseizure medications and dietary treatments. It is not fully understood how VNS therapy works, but the theory is that the VNS over time modulates nerve pathways involved in seizures. This gives extra stimulation at pre-programmed settings. In addition, the pulse generator can be manually activated in between programmed stimulation times by the child or caregiver, by placing a provided magnet over the pulse generator and then removing it. It is individually programmed to automatically stimulate in the background, typically ON for 30 seconds and OFF for 3 minutes. The pulse generator is programmed to stimulate in two ways. Vagus nerve stimulation (VNS) is a treatment for uncontrolled epilepsy. VNS therapy reduces the frequency and severity of epileptic seizures in some children. VNS therapy involves insertion of a pulse generator, similar to a heart pacemaker, under the skin on the chest that sends intermittent electrical signals to the brain by stimulating the left vagus nerve in the neck.
