Práce je věnována vzájemnému ovlivnění epilepsie a spánku. Tato interakce se uplatňuje na úrovni cirkadiálního cyklu spánku a bdění, následně na úrovni spánkové makrostruktury a konečně na úrovni mikrostruktury spánku. Na úrovni spánkové mikrostruktury je významný vztah epileptických iktálních i interiktálních fenoménů k cyklickému alternujícímu vzorci (cyclic alternating pattern, CAP). Fyziologický význam CAP spočívá v cyklickém střídání excitace a útlumu v NREM spánku. Jeho morfologie je odlišná podle hloubky NREM spánku. V REM spánku se CAP neprojevuje. Ve speciální části je popsána interakce spánku a jednotlivých typů epilepsie.Samostatně jsou zmíněny věkově vázané spánkové epileptické syndromy. Ve skupině generalizovaných epilepsií je zvlášť významný vztah juvenilní myoklonické epilepsie a příbuzných syndromů ke spánkové deprivaci. Významnou a častou vazbu na spánek mohou mít všechny typy frontálních záchvatů, obligatorně pak autozomálně dominantní noční frontální epilepsie.

The research has dealt with studying the epilepsy–sleep interaction. This is applied at the level of circadian cycle of sleep and waking, then at the level of sleep macrostructure and, finally, at the level of sleep microstructure. At the sleep microstructure level, the relation of epileptic ictal as well as interictal phenomena to the cyclic alternating pattern (CAP) is significant. Physiological meaning of CAP consists in cyclic alternations of excitation and inhibition of NREM sleep. Its morphology differs according to the depth of NREM sleep. CAP is not manifested in REM sleep. In a special part there is described the interaction of sleep and individual types of epilepsy. Age-related sleep epileptic syndromes are mentioned separately. The relation of juvenile myoclonic epilepsy and allied syndromes to sleep deprivation is especially significant in a group of generalized epilepsies. All the types of frontal seizures, obligatorily autosomal dominant nocturnal frontal epilepsies can have important and frequent bond to sleep.

OBJECTIVE: Over the past decade, concurrent with increasing social media use (SMU), there has been a shift toward poorer sleep among adolescents in many countries. The purpose of this study was to examine the cross-national associations between adolescent SMU and sleep patterns, by comparing 4 different categories of SMU (nonactive, active, intense, and problematic use). DESIGN, SETTING, AND PARTICIPANTS: Data were from 86,542 adolescents in 18 European and North American countries that participated in the 2017/18 Health Behaviour in School-aged study. MEASUREMENTS: Mixed-effects linear regression models were used to examine cross-national associations between 4 SMU categories and adolescent sleep duration, bedtime and social jetlag derived from self-reported data. RESULTS: For all countries combined, nonactive SMU was associated with longer sleep, earlier bedtimes, and less social jetlag, compared to active SMU, although the differences were minor. By comparison, intense and problematic SMU were associated with less sleep and later bedtimes on both school and nonschool days, and greater social jetlag, compared to active SMU. While findings were relatively consistent between countries, some differences were observed, suggesting that the national and cultural context may be important in interpreting results. CONCLUSIONS: These findings suggest that both intense and problematic SMU are associated with poorer sleep patterns in adolescents across most countries. Further research is needed to identify effective policies, programs, and messaging to promote the healthy use of social media and prevent potential negative impacts on adolescent sleep.

PURPOSE: Insufficient and poor sleep patterns are common among adolescents worldwide. Up to now, the evidence on adolescent sleep has been mostly informed by country-specific studies that used different measures and age groups, making direct comparisons difficult. Cross-national data on adolescent sleep that could inform nations and international discussions are lacking. We examined the sleep patterns of adolescents across 24 countries and by gender, age, and affluence groups. METHODS: We obtained sleep data on 165,793 adolescents (mean age 13.5 years; 50.5% girls) in 24 European and North American countries from the recent cross-sectional Health Behaviour in School-aged Children surveys (2013-2014 and 2017-2018). For each country, we calculated the age-standardized mean in sleep duration, timing, and consistency and the proportions meeting sleep recommendations on school and nonschool days from self-reported bedtimes and wake times. We conducted stratified analyses by gender, age, and family affluence group. RESULTS: Adolescent sleep patterns varied cross-nationally. The average sleep duration ranged between 7:47 and 9:07 hours on school days and between 9:31 and 10:22 hours on nonschool days, and the proportion of adolescents meeting sleep recommendations ranged between 32% and 86% on school days and between 79% and 92% on nonschool days. Sleep patterns by gender and affluence groups were largely similar, but older adolescents slept less and went to bed later on school days than younger adolescents in all countries. CONCLUSIONS: The sleep patterns of adolescents vary across countries and sociodemographic groups. Insufficient sleep on school days is common in many countries. Public health and policy efforts to promote healthy adolescent sleep are encouraged.
