Official title

An Investigation of the Relationship Between Donepezil Enhanced REM Sleep, Sleep Architecture and Behavior in the Prepubertal Child With Autism

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study will test whether donepezil (Aricept(Registered Trademark)), a drug that is approved by the Food and Drug Administration to treat Alzheimer's disease, can increase rapid eye movement (REM) sleep in children with autism and autism spectrum disorder (ASD). Some children with autism and ASD spend very little time in REM sleep. In some studies, decreased REM sleep has been associated with learning and behavior problems. Donepezil can increase REM sleep in some adults with different disorders. If it can increase REM sleep in children in this study, it might be able to be used in future studies to see if it can help learning and behavior problems in children with autism and ASD. Children between 2 and 10 years of age with autism or an ASD whose percentage of REM sleep time is well below the average for children of the same age may be eligible for this study. Candidates are screened with a medical history, physical and neurological examinations, blood tests, electroencephalogram (EEG) and a sleep study. The sleep study requires an overnight stay at the NIH Clinical Center in which the child is monitored with electrodes for EEG and heartbeat recording, a tube taped below the nose to measure airflow, a probe on a finger to record oxygen levels and a small watch-like machine on the wrist to record movements. Participating children may be required to have up to six overnight stays for sleep studies at the Clinical Center. The children start by taking 1.25 mg of donepezil for 2 to 4 weeks. Then they are admitted to the NIH Clinical Center for a sleep study, blood tests and EKG. Those whose REM sleep increases to normal levels stay on 1.25 mg of donepezil for 8 more weeks, after which they are admitted to the Clinical Center for a final physical examination, blood draw and sleep study. That ends their participation in the study. Children whose REM sleep does not increase to normal on 1.25 mg of donepezil are given a higher dose (2.5 mg) for 2 to 4 weeks, and the above procedure is repeated. Those whose REM sleep does not increase to normal on 2.5 mg of donepezil take 5 mg of the drug for 2 to 4 weeks, and the above procedure is repeated once more. Children whose REM sleep does not increase to normal on 5 mg of donepezil stop the medication and end their participation in the study. At each study visit, study researchers talk to the parents and examine the children to determine if donepezil is affecting the child's behavior and if the child is hav...
