Eyelid myoclonia with absences: routine EEG is sufficient to make a diagnosis.

Purpose: To identify the prevalence, clinical characteristics and routine EEG features of the syndrome of eyelid myoclonia with absences (EMA) using a retrospective case control study design.

Methods: EEGs from 1996 to 2005 were searched using the following keywords: eyelid flutter, eyelid blinking, tics, idiopathic generalized epilepsy, clinical absence, atypical absence and photoparoxysmal response. During the same period, patients with a diagnosis of idiopathic generalized epilepsy were identified.

Do clinical variables predict an abnormal EEG in patients with complex febrile seizures?

Purpose: Febrile seizures are the commonest convulsive event in children younger than 5 years of age (incidence of 2-5%). Electroencephalography (EEG) is not indicated in the work up of simple febrile seizures. Information about its role in the assessment of complex febrile seizures (CFSs) is unclear and EEGs are frequently ordered.
