Vagus nerve stimulation for the treatment of intractable epilepsy.
Vagus nerve stimulation is a safe and reliable treatment adjunct for patients with medically intractable epilepsy. It is both a preventive and abortive form of therapy, potentially effective against both partial and generalized seizures in adults and children. Vagus nerve stimulation also has a number of serendipitous effects on mood, memory and attention, and has been approved for the treatment of refractory depression. Owing to its pleiotropic effects, it also holds promise for several other diseases. Its principal limitations are its unknown mechanism of action, the low likelihood of complete cure and the inability to predict which patients will derive substantial benefit. This article reviews the theoretical rationale, practical background and clinical applications of vagus nerve stimulation therapy.
