NeurologyAdvisor: Children with and without attention deficit hyperactivity disorder (ADHD) do not have significantly different cyclic alternating pattern (CAP) analyses and interval distributions.
They present with high CAP rates, which is normal for peripubertal children, according to study results published in the Journal of Sleep Research.
A team of researchers in Switzerland and Italy conducted a study to determine CAP in children with ADHD who may be considered to have sleep disorders. They conducted the analysis of the visual cyclic alternating pattern in a blinded manner.
A total of 27 children with ADHD (mean age, 10.53 years; girls, 8) and 23 controls (mean age, 10.22 years; girls, 11) underwent a full sleep investigation, which included video-polysomnography. The 27 children with ADHD were classified into the following sleep phenotypes: obstructive sleep apnea (OSA; n=11), interictal epileptiform discharges (IEDs; n=6), narcolepsy-like (n=2), sleep onset insomnia (SOI; n=3), movement disorder (n=4), and disorder or arousal (n=1).
