Driving after vagus nerve stimulation therapy: Is it possible?

Area of Science:

• Neurology
• Neurosurgery
• Epilepsy Management

Background:

• Driving is a crucial goal for individuals with epilepsy.
• Drug-resistant epilepsy (DRE) significantly impacts patient autonomy and independence.
• Vagus nerve stimulation (VNS) is an established neuromodulation therapy for epilepsy.

Purpose of the Study:

• To determine the proportion of DRE patients eligible to drive after VNS treatment.
• To assess the impact of VNS on seizure control and driving eligibility.
• To evaluate the safety and tolerability of VNS in this patient cohort.

Main Methods:

• Retrospective observational study of 87 DRE patients treated with VNS for ≥12 months.
• Classification of patients into 'VNS responders without additional intervention' and 'VNS responders with additional intervention'.
• Assessment of driving eligibility based on Irish Medical Fitness to Drive regulations for Group 1 vehicles.

Main Results:

• 17.2% (15/87) of patients became medically eligible to drive.
• Eleven patients were seizure-free, three had nondisabling focal seizures, and one had sleep-related seizures.
• Most patients achieved driving eligibility without increased anti-seizure medication (ASM) burden; VNS was well-tolerated.

Conclusions:

• VNS can significantly improve seizure control in DRE patients, leading to driving eligibility.
• Neuromodulation with VNS offers a potential pathway to enhanced patient autonomy and independence.
• VNS demonstrates a valuable role in epilepsy management beyond its palliative classification.
