A novel mutation in KCNQ3-related benign familial neonatal epilepsy: electroclinical features and neurodevelopmental outcome Volume 21, numéro 1, February 2019

Figure 1

Electroclinical phenotype of the presented patient with BFNE. The seizure, following active sleep and arousal (A), is characterized by tonic extension and adduction of the upper limbs, flexion of the lower limbs, left trunk and head rotation associated with shallow breathing, tachycardia, and generalized decrease in EEG amplitude (B). The tonic seizure evolves into a vibratory phase (C), and then gradually into bilateral asynchronous clonic movements of the limbs and ocular-facial regions associated with bicentral sharp-wave discharges (D).
