Restless legs syndrome and related disorders - Highlights
Description
An in-depth report on the causes, diagnosis, treatment, and prevention of RLS.Alternative Names
Ekbom's syndrome; Nocturnal leg cramps; Periodic limb movement disorder
Highlights:
Overview
- Restless legs syndrome (RLS) is a poorly understood movement disorder affecting 3 - 15% of the general population. RLS can affect both children and adults.
- The core symptom of RLS is an irresistible urge to move the legs.
- Episodes of RLS usually develop between 10 p.m. and 4 a.m.
Risk Factors
- As many as two-thirds of people with restless legs syndrome (RLS) have a family history of the disorder.
- About 20% of pregnant women report having RLS. The condition usually goes away about a month after delivery.
- Between 20 - 62% of people undergoing dialysis report restless legs syndrome.
- Certain medical conditions, medications, and environmental stresses can cause RLS.
Medications
- The American Academy of Sleep Medicine recommends medications for restless legs syndrome (RLS) or periodic limb movement disorder (PLMD) only for persons who fit strict diagnostic criteria, and who experience excessive daytime sleepiness as a result of these conditions.
- Lifestyle changes, including bedtime stretching exercises, and over-the-counter pain relievers should be the first form of treatment.
- People with RLS should have a test for iron deficiency. If they are iron deficient, they should start treatment with iron supplements.
- Dopaminergic drugs (drugs that increase levels of dopamine) are the standard medicines for treating severe RLS, PLMD, or both.
- Other drugs may be helpful if dopaminergic drugs fail, or for patients who have frequent -- but not nightly -- symptoms. These include opiates (pain relievers), benzodiazepines (sedative hypnotic drugs), or anticonvulsants. However, benzodiazepines and opiates can become habit forming and addictive.
