Nerve agents are a class of phosphorus-containing organic chemicals (organophosphates) that disrupt the mechanism by which nerves transfer messages to organs. The disruption is caused by blocking acetylcholinesterase, an enzyme that normally destroys acetylcholine, a neurotransmitter.
There are several ways to treat epilepsy. How well each treatment works varies from one person to another. Vagus nerve stimulation therapy is a form of treatment for people with epilepsy whose seizures are not controlled with medication. What are the vagus nerves? The vagus nerves are a pair of nerves that start in the brain and run through the body. They send and receive messages between the brain and the body. What is VNS therapy and how does it work? Vagus nerve stimulation (VNS) therapy is a type of treatment for epilepsy that involves a stimulator (or 'pulse generator') which is connected, inside the body, to the left vagus nerve in the neck. The stimulator sends regular, mild electrical stimulations through this nerve to help calm down the irregular electrical brain activity that leads to seizures.
