P232 Attention deficit hyperactivity disorder in children; clinical and polysomnographic study

Abstract

Objectives Attention deficit hyperactivity disorder (ADHD) is a common pediatric neurodevelopmental disorder. The core symptoms include a functionally significant level of inattentiveness and distractibility. The aim of the present study is to detect the abnormalities in clinical andpolysomnography (PSG) studies in children with ADHD. It aims at finding the relation between ADHD symptoms severity and results of sleep studies, and exploring the correlations between them. Methods The study included 40 ADHD patients and 40 healthy control children. All patients and controls were subjected to history taking, clinical examination, psychaitric assessment, and then to electrophysiological studies including overnight long-term electroencephalography (EEG) and PSG. Results: EEG results showed increased theta activity, central sharp waves and generalized spikes, sharp and slow waves. PSG studies revealed statistically significant increased nocturnal movements and greater night-to-night variability in sleep patterns among children with ADHD, with otherwise inconsistent differences in sleep architecture between children with and without ADHD. Discussion: Some of our results came in agreement with other simulating researches, however, video monitoring may be used in future studies to detect any subtle events. Conclusion ADHD is frequently associated with sleep-disordered breathing and limb movement disorder. Significance EEG abnormalities and sleep abnormalities can play a role in the etiology or even accentuation of ADHD. Aiming at their treatment can ameliorate the symptoms of the disease.
