These options may include resective or laser surgeries and implantable neuromodulation devices such as a vagal nerve stimulator, deep brain stimulator, or responsive nerve stimulator.
The antiepileptic effect of vagus nerve stimulation increases over several months: after two years around half of VNS patients experience a reduction of their seizures by at least 50% [51] [52] and after 10 years the average seizure reduction is around 75% [53] Furthermore, in most patients mood (VNS has a significant anti-depressent effect and ...
