title: Sleep disturbance, daytime sleepiness, and neurocognitive performance in children with juvenile idiopathic arthritis.
abstract: OBJECTIVE
  To compare daytime sleepiness and neurobehavioral performance in children with active and inactive juvenile idiopathic arthritis (JIA), and explore relations among measures of sleep disturbance, daytime sleepiness, and neurobehavioral performance.
  
  
  METHODS
  Cross-sectional, comparison.
  
  
  METHODS
  A university-based research sleep laboratory.
  
  
  METHODS
  Seventy (70) children 6-11 years of age with active or inactive JIA.
  
  
  RESULTS
  Self-reported daytime sleepiness, multiple sleep latency tests (MSLTs), and computerized neurobehavioral performance test scores were obtained after 2 nights of polysomnography. Children with active disease (mean physician global rating score = 2.9 +/- 1.9 SD) showed shorter mean MSLT latency (15 +/- 6.0 min) than those with inactive disease (16.5 +/- 5.5 min, P < 0.03). Scores on neurobehavioral performance tests showed no group differences. However, number of wake bouts predicted sustained visual attention (rapid visual processing, P < 0.05) and apnea hypopnea index (AHI) predicted reaction time (P < 0.0001), after controlling for age, IQ, medication, and disease status.
  
  
  CONCLUSIONS
  Indices of sleep disturbance were associated with validated tests of neurobehavioral performance in JIA, regardless of disease activity. Additional research is needed about the extent of sleep disturbances in relation to neurocognitive performance in JIA and compared to healthy children.
