title: [Neurocognitive and behavioural abnormalities in paediatric sleep-related breathing disorders].
abstract: BACKGROUND
  Behavioural and neurocognitive abnormalities in children may be a consequence of sleep-related breathing disorders. The effectiveness of assessments based on questioning parents is dubious and objective assessment tools are therefore required.
  
  
  OBJECTIVE
  To ascertain the impact of these abnormalities in children with sleep-related breathing disorders and compare the reliability of questioning parents in relation to validated psychological tests.
  
  
  METHODS
  A prospective study was performed on 20 children with sleep-related breathing disorders and 20 healthy control children between 3 and 12 years of age. Both groups were subjected to a battery of validated psychological tests. The results of both groups were compared with each other and with the response to clinical questionnaires given to parents in the problem group.
  
  
  RESULTS
  More than 75% of the cases in the problem group presented abnormalities with regard to attention, anxiety, memory and spatial structuring. The percentage involvement in all concepts was higher in the problem group. Comparisons of attention (40% of children affected in the control group and 80% in the problem group), memory (50% and 84.2%), and spatial structuring (45% and 75%) were statistically significant. More abnormality was observed in the parameters assessed with psychological tests than the equivalent concept obtained from interviewing the parents. Comparison of abnormal concentration assessed from the questionnaires (40% of children affected) with attention during the psychological test (80%), memory (15% and 84.21%), and delayed language development (10%) compared to spatial structuring (75%) was statistically significant.
  
  
  CONCLUSIONS
  A high prevalence of behavioural and neurocognitive abnormalities was observed in children with sleep-related breathing disorders compared to a control group of healthy children. The use of objective assessment such as psychological tests revealed more abnormalities than were expressed by parents in response to clinical interviews.
