Periodic Limb Movement Disorder Directory

Periodic limb movement disorder is a condition in which a person's legs and sometimes arms move uncontrollably during sleep -- without having restless legs syndrome. Underlying causes of the condition may be sleep apnea, iron deficiency anemia, a thyroid problem, or infection. A detailed medical examination and polysomnography, a sleep lab test, can help confirm a diagnosis of periodic limb movement disorder.
