Abstrakt:	Study Objectives: Restless sleep disorder (RSD) is a newly defined sleep disorder in the pediatric age group. Here, we investigated the frequency of RSD and the sleep characteristics in children with NREM (non-rapid eye movements) parasomnias associated with RSD. Methods: We analyzed all patients with NREM parasomnias for the last 1 year, and investigated the clinical and polysomnographic characteristics. Results: Twenty-eight children with NREM parasomnias and age- and gender-matched 20 healthy children were analyzed. The diagnosis of RSD was made in eight children with NREM parasomnias (28.6%), and none of the children had RSD in controls (p = 0.008). The most common diagnosis among children with RSD was somnambulism (six children), but not significantly (p = 0.308). Sleep efficiency was lower in children with RSD than those without RSD (p = 0.033). In cyclic alternating pattern analysis (CAP), CAP rate, durations and the indices of phases A1, A2, and A3 were significantly higher in children with NREM parasomnias in compared to controls. CAP parameters between children with or without RSD; however, were similar, except for higher index of phase A3 in children with RSD, suggesting arousal reactions accompanying RSD. Conclusions: We demonstrated that RSD was present in almost one third of the children with NREM parasomnias. Sleep quality was worse in children with NREM parasomnias and RSD. An increase in sleep instability compatible with NREM parasomnia was present, while an increased phase A3 in RSD was remarkable. RSD is associated with a worse sleep quality and increased arousals, and should be questioned in children with NREM parasomnias. (© Sleep Research Society 2021.
