Prevalence Of Periodic Limb Movement Disorder In Intellectually Disable Population

Abstract

Abstract: Background: Periodic limb movement Disorder (PLMD) is defined as presence of repetitive limb movements during sleep, seen in 4-11% in general population. PLMD is known to cause sleep fragmentation leading to daytime consequences. Intellectual developmental disorder is a disorder known to have intellectual and adaptive functioning deficits. In case, PLMD is present in Intellectual disability then the problems faced by such population further magnify. Method: Local areas of Thane and Nasik were approached. After consent from parents 27 participants underwent nocturnal polysomnogram. Scoring of the study was done as per AASM criteria. Result: Participants positive on PLMD were 51.48%. Polysomnography findings showed TST 6hrs, sleep onset 38.35 mins, wake after sleep onset 42.23 mins, Stage 1-1.6%, Stage 2- 49.35%, REM- 17.82%, Sleep Efficiency- 77.5%. Conclusion: The paper highlights results pertaining to determining prevalence of periodic limb movement disorder in intellectually disabled population by polysomnography. The results have qualitatively improved perception of practitioners of medicine as well as parents and guardians of intellectually disabled persons with regard to physical disorders among them.
