Abstract
Among 105 participants, ADHD participants scored in the mild insomnia range and showed reduced sleep quality compared with controls.
- ADHD participants exhibited lower sleep quality than matched controls.
- No significant differences in bedtime or mid-sleep time were found between ADHD and control groups.
- Sleep quality was consistent across stimulant, nonstimulant, and unmedicated groups.
- A correlation was observed between later timing of stimulant dosing and later sleep times among ADHD participants.
- A potential phenotype of ADHD without circadian delay was identified, characterized by insomnia and sleep quality disturbances.
