“…(17) It has been demonstrated (16,18) that epileptiform discharges in NREMS, leading to arousal, form stage shifts.Several studies have evaluated such sleep parameters as sleep duration, sleep onset latency, sleep staging, wakefulness after sleep onset, sleep efficiency, REMS latency and duration, arousal index, apnea-hypopnea index, cardiac events, and periodic limb movements during sleep. (16) Sleep instability (difficulties in initiation and maintenance of sleep) in JME patients was confirmed in many studies. According to research by P.Kristian et al, (19) which was confirmed by others, (16) patients had reduced sleep efficiency, increased sleep onset latency, and increased wake percentage.…”
