Timing in auditory processing in children with ADHD with sleep disorder

We aimed to characterize the impact of obstructive sleep apnoea (OSA) over cerebral correlates of attention and categorization timing in children with attention deficit hyperactivity disorder (ADHD) and OSA. 61 participants aged 6 to 17 years with ADHD underwent one overnight polysomnography and daytime P300 auditory evoked potential test divided into three repeated series. OSA was present in 42.6% of the sample and correlated to three auditory evoked potential tests by lower amplitudes (r=.79; r=.77, r=.81, p<.000) and longer latencies (r=.60; r=.57; r=.76, p<.000). This study has found evidence of an association between OSA and timing processing to auditory stimuli. (C) 2014 The Authors. Published by Elsevier Ltd.
