Objective: The poor sleep quality of epileptic patients may be partly due to the occurrence epileptiform discharges (EDs). We observed the number of interictal discharges in each sleep stage and explored the associations between EDs and sleep phases in epileptic patients.
Methods: Two hundred epileptic patients and 182 healthy volunteers were enrolled in the current study. For all subjects, video electroencephalography (EEG) monitoring and 24-hr night polysomnography were conducted to detect EDs and analyze the sleep structures.
Results: EDs were detected in 91% of epileptic patients with the most frequent cases from the temporal lobe. The EDs detected during waking, sleeping, or both waking and nonrapid eye movement (NREM) sleep stages 1-2 accounted for 7.1%, 19.2%, and 25.3% of the total patients, respectively. EDs were rare during NREM stages 3-4 with 1.1% of total patients mainly in the central-temporal lobe. The total sleep time and time spent in REM were similar between the epileptic patients and healthy volunteers. However, epileptic patients spent a significantly longer mean sleep time in NREM stages 1-2 (293.91 ± 27.57 min vs. 223.17 ±15.28; p = .000) and less in NREM stages 3-4 (50.11 ± 12.12 min vs. 133.96 ± 10.77; p = .000) than healthy volunteers. Furthermore, asymmetric sleep spindles and fragmentary sleep structure as well as high inversion frequency were found in 26.7% and 43.3% of epileptic patients, respectively.
Conclusion: Combination of long-term video EEG with polysomnography is a useful method to analyze associations between EDs and the sleep-wake cycle. This strategy can also help identify the nature of sleep disorders in epileptic patients, which may improve the treatment efficacy.

Background: Aarskog-Scott syndrome (AAS) is a rare condition with multiple congenital anomalies, caused by hemizygote variants in the gene. Its description was based mostly on old case reports, in whom a molecular diagnosis was not always available, or on small series. The aim of this study was to better delineate the phenotype and the natural history of AAS and to provide clues for the diagnosis and the management of the patients.

This study intents to detect graphical network features associated with seizure relapse following antiseizure medication (ASM) withdrawal. Twenty-four patients remaining seizure-free (SF-group) and 22 experiencing seizure relapse (SR-group) following ASM withdrawal as well as 46 matched healthy participants (Control) were included. Individualized morphological similarity network was constructed using T1-weighted images, and graphic metrics were compared between groups.

Objective: This study was undertaken to describe incidence and distribution of seizures, etiologies, and epilepsy syndromes in the general child and youth population, using the current International League Against Epilepsy (ILAE) classifications.
Methods: The study platform is the Norwegian Mother, Father, and Child Cohort Study (MoBa). Epilepsy cases were identified through registry linkages facilitated by Norway's universal health care system and mandatory reporting to the Norwegian Patient Registry.
