Epileptiform electroencephalogram discharges increase seizure recurrence risk in patients with acute symptomatic seizure due to a structural brain lesion

Acute symptomatic seizure has been defined as a seizure that occurs in close temporal association with an acute central nervous system (CNS) insult. This may be metabolic, toxic, structural, infectious, or inflammatory [1]. Acute symptomatic seizures are not considered in the definition of epilepsy and differ from unprovoked seizures in a number of ways. First, they have a clearly identifiable, acute cause that occurs close in time to the seizure, and second, they do not usually recur once the cause is resolved and CNS integrity re-established [2].
