Abstract

Abstract: Introduction: Narcolepsy is known to be associated with sleep related movement disorders (SRMD) including periodic limb movement and restless leg syndrome. However, there is paucity of data comparing the clinical characteristics of children with narcolepsy with and without SRMD. Methods: Retrospective chart review of all children presenting to the sleep clinic for sleep problems between March 2016 to June 2017 was performed. Demographics, sleep intake patient questionnaires and ICD-10 codes for comorbidities and sleep diagnoses were collected. Children with diagnosis of narcolepsy (ICD-10 G47.4) were included in this study. Cohort was divided into 2 groups- with and without co-existing diagnoses of sleep related movement disorders (ICD-10 G47.6). Demographics, presenting symptoms, Epworth sleepiness scores and prevalence of sleep comorbidities were compared using T-test (continuous) and Chi square (categorical). Unadjusted odds ratio was calculated for demographics and presence of SRMD. P value of <0.05 was considered significant. Results: 28 (F=14, 50%) children with narcolepsy were included. 25% children were diagnosed with SRMD. Mean (SD) age of children with SRMD presenting to the sleep clinic was 11.14 (5.08) years while mean age (SD) of children without SRMD was 9.52 (3.87) years. Age and race of children with and without SRMD were not statistically different. There was an increased prevalence of females in the group with narcolepsy and SRMD compared to the group without SRMD (86%vs38%, p=0.029). Epworth sleepiness score was not statistically different between the 2 groups. Female gender increased the odds of SRMD in children with narcolepsy (OR:9.75, 0.98- 96.56). Conclusion: Children with narcolepsy can present with comorbid sleep related movement disorder. Females were more likely to present with associated SRMD compared to males. Support: None
