Answer

Positive predictors of a favorable outcome with VNS therapy include posttraumatic epilepsy and tuberous sclerosis. Few patients achieve complete seizure freedom with VNS, and about a quarter of patients receive no benefit in their seizure frequency. [67] Some patients have clinical improvement in terms of milder and shorter seizures.
