Restless legs syndrome and periodic limb movements disorder in the pediatric population.
OBJECTIVE
Restless legs syndrome (RLS) and periodic limb movements of sleep (PLMS) are common neurological disorders in childhood which are usually underdiagnosed. As many pediatricians and pediatric pulmonologists with interest in sleep medicine will be encountering children with RLS and PLMS in their practice, we feel a comprehensive review of these disorders from a pediatric perspective would be very important in understanding basic pathophysiology, clinical features in early diagnosis, and effective management.


RESULTS
There has recently been increased awareness about these disorders in children, and the American Academy of Sleep Medicine has recently published pediatric specific diagnostic criteria. There have also been exciting discoveries into the basic pathophysiology of these conditions which have helped to better understand these disorders. Genetics plays a very important role in their development, and current management strategies have been very successful in treatment of these conditions.


CONCLUSIONS
RLS occurs in 1 out of 120 school-age children. In many children, diagnosis is not even suspected as these children present with atypical symptoms and associated comorbid conditions. In this review, we will discuss RLS and PLMS in the pediatric population and briefly review their pathophysiology, clinical presentation, risk factors, neurobehavioral consequences, and newer diagnostic criteria along with recent advances in their management.
