Sleep, cognitive functions, behavioral, and emotional disturbance in self-limited focal childhood epilepsies.

Background: Self-limited focal epilepsies of childhood, including self-limited epilepsy with centrotemporal spikes (SeLECTS), idiopathic childhood occipital epilepsy of Gastaut (ICOE-G), and self-limited epilepsy with autonomic seizures (SeLEAS), were considered benign conditions. However, recent research assumed potential adverse impacts on sleep, cognition, behavior, and emotional well-being. Our aim was to investigate the effects of self-limited focal epilepsies on sleep architecture, cognitive functions, behavior, and emotional disturbances in drug naive children. A cross-sectional study was conducted on 46 newly diagnosed children (ages 6–12) with SeLECTS (n = 22), ICOE-G (n = 12), SeLEAS (n = 12), and 20 healthy controls. Overnight polysomnography was performed. Cognitive assessments included intelligence scales, executive function tests, verbal fluency, visuospatial abilities, and memory. Behavioral and emotional problems were evaluated using standardized questionnaires and psychiatric interviews. Results: Children with epilepsy exhibited significant disturbances in sleep architecture, impairments in cognitive domains (executive functions, verbal fluency, visuospatial skills, and memory), and higher rates of internalizing/externalizing problems, social issues, attention deficit hyperactive disorder, depression, and anxiety compared to controls. No significant differences were found among the three epilepsy subtypes. Conclusion: Self-limited focal epilepsies in childhood are associated with sleep disruption, cognitive deficits, behavioral issues, and psychiatric comorbidities, challenging their traditional "benign" perception. Comprehensive management approaches addressing these multidimensional impacts are warranted. [ABSTRACT FROM AUTHOR]
