Abstract

This dissertation aims to gain more insight into the effects of vagus nerve stimulation (VNS) in children with hard-to-treat epilepsy. VNS appears to be both a tolerable and safe form of treatment.
Predictors of a favourable outcome with VNS therapy were missing at the time of this study, but research has revealed that lower baseline plasma levels of interleukin-6 is associated with a greater reduction in seizure frequency with VNS. This therefore appears to be a favourable prognostic factor. The effect of VNS on epileptic seizures could be partly explained by the way VNS influences the degradation of tryptophan, a neurotransmitter involved in mood regulation, among other things. An improvement in mood was especially seen after a prolonged period of therapeutic stimulation, independent of improved seizure control. Finally, VNS was not found to have a negative effect on behaviour or cognition.
