Background:
Periodic limb movements in sleep (PLMS) may occur in up to 6% of the general population and is more common in the elderly.
Material And Methods:
Based on relevant literature and recent guidelines from the American Academy of Sleep Medicine, we present an overview of symptoms, diagnostic examinations and treatment of periodic limb movements in sleep, including its relation to restless legs. A short case history is also presented.
Results:
Patients with periodic limb movements in sleep may or may not have other symptoms, such as insomnia and excessive daytime sleepiness. Polysomnography is necessary for the diagnosis. Only patients who meet specific diagnostic criteria should be treated pharmacologically. Our patient was examined by polysomnography and actigraphy before and during pharmacological treatment.
Interpretation:
The concept and treatment of periodic limb movements in sleep is controversial.
