Children with Asperger syndrome (AS) are more likely to have sleep disorders than other children, a study shows.
Experts examined the daytime and nighttime sleep patterns of 8 children with AS, 10 with autism and 12 healthy children.
Children were also examined on the Autism Diagnostic Observational Schedule and assessed through a child behaviour checklist.
Results show that half of children with AS were reluctant to go to bed, while 85% had difficulty getting to sleep at night.
Another 50% of children with AS felt unrefreshed in the morning and 87% felt sleepy during the day.
Children with AS had a slower cyclic alternating pattern (CAP) than healthy children.
Experts say that children in preschool should sleep 11-13 hours a night and should encourage parents to set a consistent bedtime and not let their children fall asleep while being rocked, held, fed or nursed.
