Periodic Limb Movement Disorder Happens While Sleeping

Periodic limb movement disorder (PLMS) occurs when your legs involuntarily move while sleeping. It can cause significant problems with nighttime sleep, which in turn leads to daytime drowsiness.

“PLMS can be the result of an underlying condition, such as diabetes, anemia, or a spinal cord injury, or it can have no known cause,” says Bradley K. Bittle, MD, FCCP, D-ABSM, pulmonologist/ sleep medicine specialist, Saint Francis Medical Partner. “Regardless of the cause, the only way to diagnose PLMS is through a sleep study at Saint Francis Healthcare System’s Sleep Disorders Center.”
