Acute symptomatic seizures: an educational, evidence-based review

Abstract

Acute symptomatic seizures occurring in close temporal relationship with an acute CNS insult are distinct from epilepsy and occur frequently in clinical practice. The aim of this educational review is to provide information on the most important aspects related to acute symptomatic seizures that will allow clinicians to accurately distinguish acute symptomatic seizures from epilepsy in their patients. We explain the definition of acute symptomatic seizures and we illustrate how acute symptomatic seizures differ from epilepsy. We describe acute symptomatic seizures in the context of their various underlying aetiologies and we discuss the approach to the management of patients with acute symptomatic seizures.

Keywords: acute symptomatic seizure; brain insult; epilepsy; provoked seizures; stroke; traumatic brain injury.
