People with<unk>  often have excessive daytime sleepiness (EDS), falling asleep during the day, trouble falling asleep at night, and difficulty staying asleep throughout the night. Patients also display involuntary<unk><unk> s that occur at<unk>  intervals anywhere from 20–40 seconds apart. They often only last the first half of the night during non-REM sleep stages.<unk> s do not occur during REM because of muscle atonia. PLMS can be unilateral or bilateral and not really symmetrical or simultaneous. PLMS is often a symptom of RLS but evidence for differences between those two sleep<unk> s was found in literature. Sleep structure differed, when RLS patients had significantly more REM sleep and less stage 1 sleep compared to<unk>  patients. Besides, PLMI was significantly higher in patients with<unk> .
