Abstract
Sleep is an essential physiologic process for health and analyzing sleep architecture helps us not only to diagnose sleep disorders, but also to understand the pathophysiology of these diseases. Therefore, this study was aimed to analyze the sleep structure in children with sleep disorders. Thirty-four children diagnosed with obstructive sleep apnea, parasomnia, or narcolepsy participated in this study from March 2008 to September 2011. Their polysomnographs were reviewed and their sleep parameters were analyzed. Their mean age was 9.3 ± 4.1 yr (range: 3–12-year-old) and male to female ratio was 3.8. Patients with obstructive sleep apnea showed increased sleep latency and total arousal index and a decreased N3 sleep compared to other groups. In children with parasomnia, apnea hypopnea index and periodic limb movement index were not increased and rapid eye movement (REM) sleep, REM sleep latency were decreased. Patients with narcolepsy showed decreased sleep latency and REM sleep latency. Among the three groups, there was no difference except apnea hypopnea index. The result showed that sleep architectures in children with sleep disorders were relatively similar to previous studies from Western countries. In addition, it was judged that this study would provide fundamental knowledge about sleep structure of Korean children. However, further studies will be required to provide better understanding about the sleep architectures in children with sleep disorders.
