Comorbidities in Attention Deficit Hyperactivity Disorder (ADHD) and
auditory processing disorders in children have been described in the literature. These
symptoms have been neglected in the evaluation and rehabilitation of these children.
Objective: The purpose of this study was to describe Long Latency Auditory Evoked
Potentials (LLAEP) in children with ADHD. Material and Method: Fifteen children
with ADHD, aged from 8 to 12 years, participated in this study. LLAEP were recorded
as children performed active frequency discrimination (P300f) and duration
discrimination tasks (P300d). Results: Data show that children with ADHD had larger
amplitude responses in P2 and N2 in the left ear, and delayed latency of N2 in the left
ear. Conclusions: The present study contributed to increased knowledge of central
auditory pathways in children with ADHD, when observed by electrophysiology
