[Idiopathic nocturnal frontal lobe epilepsy--an unusual epilepsy syndrome].
This paper provides an overview of the development of conceptions about nocturnal frontal lobe epilepsy syndrome and describes the electro-clinical characteristics, the identity of the genetic and sporadic variant, and the relationship of the EEG and clinical signs with NREM sleep specific features. The differential diagnostic difficulties and open questions on the pathomechanism are emphasized especially in relation with the lack of epileptiform EEG signs, circumscribed seizure onset zone and cognitive deficits. The relationship of frontal automatisms and NREM parasomnias are also discussed in relation of the place of nocturnal frontal lobe epilepsy among other epilepsies.
