简要总结
The purpose of this study is to examine the effect of diphenhydramine on sleep in children and adolescents with Autism Spectrum Disorder (ASD). Diphenhydramine is an anti-histaminergic agent with strong hypnotic properties. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of diphenhydramine on sleep physiology as assessed by polysomnography (PSG), actigraphy, circadian rhythm, and clinical measures.

研究组 & 干预措施
Diphenhydramine, then Placebo
Participants will first receive Diphenhydramine for a 4-week period. A 25 mg dose of Diphenhydramine will be given at bedtime for one week and then will increase to 50 mg if needed and if well tolerated.
Participants will then receive Placebo (fake tablet) for a 4-week period. A 25 mg dose of matching Placebo will be given at bedtime for one week and then will increase to 50 mg if needed and if well tolerated.
干预措施: Diphenhydramine (Drug)
