Neurostimulation Procedure - Vagus Nerve Stimulation (VNS) for Epilepsy | Beta Clinic Bonn

Vagus Nerve Stimulation (VNS) at Beta Clinic Bonn is offered as a neurostimulation option for people with severe, drug-resistant epilepsy - especially when resective epilepsy surgery is not possible or has not achieved adequate seizure control. The concept is to use the vagus nerve’s broad connections to the brain to modulate seizure networks through regular, programmed stimulation. The procedure involves securing an electrode to the vagus nerve in the neck and connecting it via an implanted cable to a pulse generator placed under the skin in the chest (similar in principle to a pacemaker). The device delivers intermittent stimulation cycles (the clinic gives an example schedule of periodic pulses), with the primary goal typically being sustained seizure reduction rather than guaranteed seizure freedom. Beta Clinic notes that a substantial share of patients can achieve a meaningful reduction in seizure frequency, while side effects like temporary hoarseness during stimulation phases can occur.
