Causes, Incidence, and Risk Factors

Restless leg syndrome is a disorder in which there is an urge or need to move the legs to stop unpleasant sensations.

Restless leg syndrome (RLS) occurs most often in middle-aged and older adults. Stress makes it worse. The cause is not known in most patients.

RLS may occur more often in patients with:

  • Chronic kidney disease

  • Diabetes

  • Iron deficiency

  • Parkinson's disease

  • ¬†Peripheral neuropathy

  • Pregnancy

  • Use of certain medications such as caffeine, calcium channel blockers, lithium, or neuroleptics

  • Withdrawal from sedatives

    RLS is commonly passed down in families. This may be a factor when symptoms start at a younger age. The abnormal gene has not yet been identified.

    Restless leg syndrome can result in a decreased quality of sleep (insomnia). This lack of sleep can lead to daytime sleepiness, anxiety or depression, and confusion or slowed thought processes.
