title: [Restless legs syndrome in patients diagnosed with attention deficit hyperactivity disorder].
abstract: BACKGROUND
  Restless legs syndrome (RLS) is a common neurological disease. RLS has been linked to various psychiatric disorders, especially with attention deficit hyperactivity disorder (ADHD).
  
  
  OBJECTIVE
  The main objective was to describe the frequency of RLS in pediatric patients diagnosed with ADHD. Secondary objectives of the study were describe other sleep disorders in ADHD patients.
  
  
  METHODS
  A multicentre prospective study was conducted in nine Spanish centers. We included children aged 6-18 years diagnosed with ADHD between January and June 2015. Data were collected by 13 researchers doctors through an interview with the parent/caregiver and with the child. To assess the degree of functioning of patients with ADHD we used the Children's Global Assessment Scale. The Sleep Disturbance Scale for Children was applied to screening sleep disorders in childhood.
  
  
  RESULTS
  A sample of 73 patients was collected. Five patients (6.8%) met diagnostic criteria for RLS: four of them definitive and one probable.
  
  
  CONCLUSIONS
  RLS is a frequent condition in adulthood but also in adolescence and childhood. ADHD patients have an increased risk of an RLS.
