What is the standard approach to assessment of an unprovoked seizure in an adult?

Abstract

Since Hong Kong is highly urbanized and acute public hospitals have been established across the city, most patients with unprovoked seizures not already receiving antiepileptic drug (AED) therapy, particularly convulsive seizures, will be admitted as emergency for assessment. A thorough history is taken from the patient and any witnesses to the seizure. This includes the circumstance of the seizures, detailed symptoms and signs experienced by the patient and witnessed by others before, during, and after the seizure, any potential precipitating factors, history of previous seizures (that the patient might have overlooked), and history of previous brain insults that might have increased the risk of epilepsy later in life, including gestational and birth history, history of childhood febrile seizure, significant head trauma, any family history of epilepsy or seizures, comorbidities, current medications, drug and alcohol abuse, and social history including employment, driving, and living circumstances. A detailed physical and neurologic examination is performed.
