Abstract

Conventional rodent models have provided invaluable tools for the discovery and characterization of antiepileptic drugs (AEDs). Nevertheless, around one third of people with epilepsy do not respond to currently available treatments, and so new AEDs are surely needed. However, traditional rodent models are expensive, pose ethical problems, and are poorly suited to high-throughput drug discovery. As a result, methods for front-line screening of compound libraries in simpler seizure models such as fruit flies and zebrafish have been successfully developed in recent years. Here we describe an assay of seizure-like activity using the nematode worm, Caenorhabditis elegans. Our main aim here is to explain how to perform the method, highlighting advantages and limitations of both assay and the animal model. In addition, we give examples of how the assay can be used to determine pathogenicity in epilepsy-associated genetic variants, to screen for anticonvulsants, and to identify AED mechanisms of action.
