Fig. 1From: Two novel PCDH19 mutations in Russian patients with epilepsy with intellectual disability limited to females: a case reportEEG for patient 1 during wakefulness and sleep. a. Waking EEG. Rhythmic theta-activity with tendency to hypersynchronization. Regional delta-slow accentuation in right temporal region with polyphasic potentials, but with no typical epileptiform activity at wake state. b. Sleep EEG. Regional epileptiform activity – sharp-and-slow wave discharges in the left temporal region. Moderate fusiform brush-like beta-activity accentuations in fronto-centro-temporal D > S regions. c. Sleep EEG. Regional epileptiform activity – sharp-and-slow wave discharges in the right temporal region. Preserved sleep architectonics with the presence of physiological sleep patterns (K-complexes and “sleep spindles”)Back to article page
