Circadian rhythm patterns and screen time in relation to sleep quality in adults with ADHD

This comparative study of 100 adults with ADHD and 100 healthy controls found that ADHD adults reported significantly higher screen time, more disrupted circadian rhythms, and poorer sleep quality. Biological rhythm disruption was identified as the strongest predictor of poor sleep quality across both groups, exceeding the predictive power of ADHD symptom severity or screen time alone.
