[Restless legs syndrome - an underestimated health problem in children].

Restless legs syndrome (RLS) is one of the most common neurological diseases. Even though there is a large progress in its diagnosis, pathophysiology and treatment, it still remains recognised too rarely. It is elderly people who mostly suffer from restless legs syndrome, but it is established that the disease may begin in childhood. The aim of this study is to present the diagnostic criteria and differential diagnosis in cases of this syndrome, in children. Correct diagnosis of restless legs syndrome is a starting point for epidemiological studies on the incidence of RLS in children.
