ClinConnect Summary
This clinical trial is studying how melatonin, a hormone that helps regulate sleep, can help children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) and sleep problems. Researchers want to find out if some children have a natural delay in releasing melatonin, which could affect how well melatonin treatment works for them. The goal is to better understand how melatonin functions in children with different psychiatric conditions and to see if there are differences in melatonin release between those with chronic sleep issues and those without.
Children aged 6 to 13 years who have been referred for ADHD treatment and have chronic sleep problems may be eligible to participate in this study. Participants will have their melatonin levels measured and will receive melatonin treatment, allowing researchers to gather important information about its effects. It’s important to note that children with certain conditions, such as autism or a low IQ, and those who have previously been treated with melatonin, cannot participate. This trial aims to improve understanding of sleep problems in children, which could lead to better treatment options in the future.
