When an individual has a convulsive seizure, often the first impulse on the part of the public is to call 911 for an emergency medical services (EMS) response. This guide describes a variety of seizures associated with epilepsy, seizures with other potential causes, appropriate EMS response on scene, and issues to be considered when determining whether or not further medical care is warranted. This participant’s guide complements the Facilitator’s Guide for training EMS personnel in a classroom-based setting. It can also be used as a reference guide that participants can take with them after the training. These materials are provided free of charge by the Centers for Disease Control.
