Abstract
Delays in circadian rhythm are prevalent in 73-78% of individuals with attention-deficit/hyperactivity disorder (ADHD).
- ADHD is commonly associated with various sleep disorders, particularly delayed sleep phase disorder.
- Sleep disturbances may either result from ADHD or share a common genetic and etiological background.
- The relationship between ADHD symptoms and delayed sleep may be influenced by genetics, behavior, daylight exposure, and eye function.
- Treatment options aim to improve sleep quality and phase through methods like sleep hygiene, chronotherapy, and specific sleep disorder management.
- A novel perspective suggests that some ADHD symptoms may stem from chronic sleep disorders, particularly the delayed circadian rhythm.
