Background and aims Many studies have shown a significant increase in SD in neurologically impaired patients. The aim of study was to evaluate the prevalence of sleep disturbances (SD) among the children with cerebral palsy (CP) with or without co-morbidity with Epilepsy.
Methods A structured sleep-waking questionnaire was developed on the basis of Child Sleep Questionnaire for Parents and the Paediatric Sleep Questionnaire. Subjects were recruited from the Institute of Neurology and Neuropsychology/Tbilisi/Georgia.
Results 165 1-to-8-years-old children with CP and 359 age and sex-matched subjects were selected. 85 patients with CP had Epilepsy. Different SD were identified in 64.8% (n = 107) of children with CP vs. 20.3% (n = 73) in healthy children. Sleep disorder breathing (SDB) was the commonest among the children with CP 58.78% (n = 97) vs. 8.07% (n = 29) in controls. Other main problems in neurologically impaired children were problems with sleep onset 41.2% (n = 68) and sleep maintenance 39.4% (n = 65). The frequency of both was about 4-fold higher than in healthy controls. Sleep onset difficulty was commonest among controls 11.4% (n = 41).
SDB was more prevalent among the children with CP and Epilepsy 69.4% (n = 59) vs. 47.5% (n = 38) in children without seizures. Problems with sleep onset and maintenance were a little higher among the subjects without Epilepsy 48.75% (n = 39) and 42.5% (n = 34) correspondingly vs. 34.12% (n = 29) and 36.47% (n = 31) in children with CP and Epilepsy.
Conclusions Study shows that SD is more prevalent in neurologically impaired children. Children with CP and Epilepsy show to be at higher risk to have SDB, compared to children with CP alone;
