How is periodic limb movement disorder (PLMD) diagnosed?
Periodic limb movement disorder (PLMD) is diagnosed with a medical history, often including a sleep history from a bed partner, and a physical exam. A sleep study is usually required to detect the movements. A sleep study also can identify other conditions that may be causing symptoms, such as sleep apnea or other subtle breathing problems that may be causing movements.
Many questions remain about the nature of periodic leg movements and PLMD. Some researchers consider the movements to be normal. At least a few movements may occur during sleep in people who do not have restless legs syndrome, especially in the elderly.
