“…Specifically, prior to age 10, youth with ADHD display less REM sleep than their peers, but this trend reverses around the time of transition to middle school, and adolescents with ADHD display significantly more REM sleep than age-matched controls (Kirov & Brand, 2014). Second, children with ADHD appear to have a stronger circadian evening preference (i.e., biological bent to stay up late) in comparison to their peers (Gruber et al, 2012), though this too remains to be examined in adolescents specifically when circadian preferences markedly shift for all youth (Hagenauer, Perryman, Lee, & Carskadon, 2009). Third, youth with ADHD exhibit significantly higher intraindividual variability of sleep in comparison to their peers (Becker, Sidol, Van Dyk, Epstein, & Beebe, 2016).…”
