Slow-wave activity (SWA) of non-rapid eye movement (NREM) sleep electroencephalogram (EEG) is an electrophysiological index of sleep intensity reflecting cortical maturation. Available data on ADHD and SWA are conflicting and developmental differences, or the effect of pharmacological treatment are relatively unknown.<\/p>\n<p>Methods<\/p>\n<p>We examined, in samples (<em>M<\/em><sub>age<\/sub>=16.4, <em>SD<\/em>=1.2), of ever-medicated adolescents at-risk for ADHD (<em>n<\/em>=18, 72%boys), medication na\u00efve adolescents at-risk for ADHD (<em>n<\/em>=15, 67%boys), and adolescents not at-risk for ADHD (<em>n<\/em>=31, 61%boys) matched for chronological age, whether controlling for non-ADHD pharmacotherapy, ADHD pharmacotherapy modulates the association between NREM SWA and ADHD risk in home sleep.<\/p>\n<p>Results<\/p>\n<p>Findings indicated medication na\u00efve adolescents at-risk for ADHD exhibited greater first sleep cycle and entire night NREM SWA than both ever-medicated adolescents at-risk for ADHD and adolescents not at-risk for ADHD and no difference between ever-medicated, at-risk adolescents and not at-risk adolescents.<\/p>\n<p>Conclusions<\/p>\n<p>Results support atypical cortical maturation in medication na\u00efve adolescents at-risk for ADHD that appears to be normalized by ADHD pharmacotherapy in ever-medicated adolescents at-risk for ADHD. Greater NREM SWA may reflect a compensatory mechanism in middle-later adolescents at-risk for ADHD that normalizes an earlier occurring developmental delay.<\/p>\n<p>Keywords: sleep EEG, slow-wave activity, ADHD, medication, DREEM2 headband<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>NREM Slow-Wave Activity In Adolescents Is Differentially Associated With ADHD Levels And Normalized By Pharmacological Treatment.
