A genetic factor may be present in RLS:
up to half the persons with the condition have a family history
of it. Treatment focuses on resolving any underlying
cause of the disorder using cognitive-behavioral and sleep
hygiene therapies and, if necessary, drug therapy. For RLS,
such over the counter (OTC) medications as acetaminophen
or a nonsteroidal anti-inflammatory drug can be tried first.
In severe cases, a dopamine agonist ordinarily used in the
treatment of Parkinson’s disease may be effective.1
