Periodic Limb Movement Disorder (PLMD)

Repeated body movements characterize periodic limb movement disorder. These movements may occur in the toes, feet, ankles and/or legs, during sleep. A person may be unaware of these movements during sleep, but a sleep partner may notice them. This disorder is common in older adults and in people with restless legs syndrome.



Medicines are available for people with symptoms. Ask your doctor what medicines would be best for you.

Low blood levels of iron can also cause this disorder. If an iron deficiency is present, iron supplements may be given. Caffeine, nicotine, alcohol and certain medications can make this disorder worse.
