Sleep disorders in patients with ADHD: impact and management challenges.

Eggleston et al. (2018) pulled every paper they could find on sleep problems in people with ADHD. They read the studies and wrote a big-picture summary of how poor sleep hurts thinking, mood, behavior, and health.

Sleep disorders show up far more often in ADHD than in typical kids and adults. Yet most clinics never ask about bedtime, night waking, or daytime fatigue. The review says this miss means treatable sleep trouble stays hidden.

Scahill et al. (2025) built a new parent scale for insomnia in autism. Their work backs the same idea: you need the right tool to spot sleep issues in neurodevelopmental kids.

van Schrojenstein Lantman-de Valk et al. (2006) used wrist-watch actigraphy on adults with ID and ASD. They found no extra sleep harm from ASD. That seems to clash with D et al.’s claim that ADHD brings lots of sleep trouble. The gap is in the method: J et al. looked at total sleep time and rhythm, while D et al. counted full sleep disorder diagnoses. Different lenses, different answers.

Mikulovic et al. (2014) and Tassé et al. (2013) both show that early-rise sleep timing links to lower weight and more activity in people with ID. D et al. add the ADHD side: fixing sleep could lift daytime focus and mood, not just weight.

If you assess ADHD, add five sleep questions to your intake. A simple parent or adult rating can flag insomnia, restless legs, or delayed phase. When sleep is treated, attention and self-control often improve, cutting the need for higher drug doses. Start screening next intake; it costs one minute and can change the whole plan.
