Children with autism often have sleep problems, and therapies such as behavior therapy (applied behavior analysis [ABA]) and melatonin may be helpful in treating these sleep problems.

The goals of this study were to see what types of children with autism also have sleep problems and to see how often parents of children with autism reported sleep problems. More than half of children with autism have parents who reported sleep problems. The study showed that many children with autism have sleep problems and that sleep problems are worse in children with more severe autism. Children who were on drugs (melatonin, clonidine, and diphenhydramine) to treat sleep problems had greater sleep problems than children who did not seek treatment. In most cases children with autism slept fewer (not more) hours than children without autism.
