Lifelong and new nocturnal events found to be right frontal lobe epilepsy secondary to a cortical dysplasia.

摘要

Frontal Lobe seizures (FLE) are frequently mistaken for psycho-genie non-epileptic seizures (PNES) and other imitators of epilepsy as well as complex sleep related movement disorders and other parasomnias. In FLE, the EEG can often be obscured by artifact, it can be non-localizing, non-lateralizing or the electrographic seizure activity may simply not be seen on scalp recording due to the ictal onset being distal (deep) to the surface recording leads [1,2], Therefore, making the diagnosis is heavily dependent on clinical history and capturing several of the patient's typical spells utilizing video polysomnography (vPSG) or video EEG monitoring (vEEG) with careful review of the semiologic features of the events in question. In this atypical case the etiology of a patient's lifelong seizure disorder was discovered when, at the later age of 60, her typical events changed in semiology and frequency [3].
