The majority of children and adults with ADHD report some kind of sleep challenge — from racing thoughts at bedtime to restless limbs at night to tortured wake-up rituals every morning. Typically, these sleep disturbances are due to their energetic mix of hyperactivity, lack of focus, and, in some cases, stimulant medications. But insomnia doesn’t always mean ADHD, and other sleep disorders can mimic ADHD symptoms during daylight hours. Sleep apnea is a common culprit that's often misdiagnosed as ADHD — and vice versa. Fortunately, researchers are devising simple tests to definitively diagnose and get kids the treatment they need.
