claimPeriodic limb movements associated with sleep disruption are less common than periodic limb movements in general.

claimSleep-disordered breathing may act as a modulator that increases the association between periodic limb movements and ADHD.

claimPeriodic limb movements typically occur in the lower extremities and may result in autonomic arousal, cortical arousal, or an awakening, though the individual is typically unaware of the movements.
