VNS Therapy™ can lead to fewer seizures, shorter seizures and better recovery after seizures.
The change from regular to responsive VNS TherapyTM showed a reduction of seizure frequency
Based on the McHugh Classification of patients receiving VNS Therapy:
12 out of 19 patients (41%) who had less than 50% seizure reduction with regular VNS Therapy reported more than 50% seizure reduction with responsive VNS Therapy following a battery change.
This study was a non-controlled retrospective analysis of data where the seizure reporting is an interpretation of patients and carers.
