Consequences of Periodic Limb Movement Disorder (PLMD)

Periodic Limb Movement Disorder (PLMD) causes short arousals and disturbed sleep, which can lead to excessive daytime sleepiness (EDS). EDS is, in turn, associated with depression and other psychological issues; memory impairment; attention-deficit hyperactivity disorder (ADHD); and irritability, hyperactivity, and impulsivity in children.3  (For information on the difference between PLMD and periodic limb movements during sleep, see Periodic Limb Movement Disorder (PLMD).
