Different Periodicity and Time Structure of Leg Movements During Sleep in Narcolepsy/Cataplexy and Restless Legs Syndrome

Abstract

Most narcoleptic patients show a high number of LMs that are significantly less periodic than those of patients with RLS. PLM are in functional interrelationship with the cyclic alternating pattern, which is reduced in patients with narcolepsy; decreased arousal fluctuations during sleep may be one of the factors influencing the reduction in periodicity of LMs during sleep in narcolepsy.
