Epilepsy and driving: current status of research

Abstract

In many parts of the world, licensing guidelines state that drivers with medical conditions such as epilepsy are restricted or prohibited from driving. These guidelines are sometimes subjective and not strongly evidence-based, rendering the task of assessing fitness to drive a complex one. Determining fitness to drive is not only essential for maintaining the safety of individual drivers but has implications for the community at large. It is therefore important to review the current state of knowledge regarding epilepsy and driving in order to aid health professionals required to assess fitness to drive and to guide future research directions. This review outlines the functional impairments related to epilepsy and driving, treatment and management issues, motor vehicle crash risk for drivers with epilepsy, estimates of predicted seizure occurrence and concludes with a discussion of the international licensing guidelines and relevant legal issues. More comprehensive research, including investigation into the effects of antiepileptic medication on driving, could aid in the development of policies and guidelines for assessing fitness to drive.
