Overview of seizures.
Epilepsy is a chronic disorder characterized by recurrent unprovoked epileptic seizures. Not all epileptic seizures indicate the existence of an epileptic disorder; many represent a natural response of the normal brain to transient noxious insults that are not likely to be repeated (reactive seizures). Not only is it important to distinguish conditions associated with these relatively benign epileptic events from epilepsy, but also it is important to recognize the many types of epileptic seizures and many types of epilepsy, reflecting different underlying anatomic and pathophysiologic substrates, which determine therapy and prognosis. Acute care for an epileptic seizure, therefore, includes search for an underlying treatable cause and protection against recurrence, if necessary. Neurologic consultation in the emergency department can help avoid unnecessary diagnostic procedures and treatments, particularly in patients with reactive seizures and established epileptic disorders. Communication with the patient's continuing care physician is an essential part of the emergency department management plan.
