The movements of periodic limb movement disorder last for up to 10 seconds and may repeat after 5 to 90 seconds.
A person who has periodic limb movement disorder may wake up during the movements. This can interfere with sleep and cause sleepiness during the time the person wants to be awake.
If periodic limb movement disorder is causing problems, a doctor may suggest medicines that prevent the movements or help with sleep during the movements.
Periodic limb movement disorder is more common in older adults than in younger people. It is diagnosed through sleep studies done in a sleep lab.
