Vagus nerve stimulation

    Fast facts

    The vagus nerve is the longest nerve in the body

    Vagus nerve stimulation (VNS) can help some people with seizure control

    The stimulator is a small electrical device, inserted into your chest wall, a bit like a pacemaker

    The VNS device sends electrical impulses via the vagus nerve to the brain, with the aim of reducing the number of seizures and making them less severe

    VNS is usually used in addition to taking epilepsy medicine, to help control seizures
