![]() Long latency potentials such as the P300 are useful in studying cognitive and attentional functions (Kahn et al., 2004). ![]() Latency is a much more reliable indicator than amplitude, as latency is difficult to alter with attention. It may provide a general index of cognitive processes, and an abnormally small or delayed P300 probably indicates some cognitive abnormality. This potential appears around 300 ms and requires attention, auditory discrimination, and memory for its generation. Recently, electrophysiologic assessment of auditory selective attention has become possible because of the advent of event-related potential (ERP) studies (Booth et al., 2005). ![]() ![]() Therefore, a selective attention deficit may be presumed in these children. Indeed, there are many behaviors that children with APD and ADHD have in common (Schochat et al., 2002).Ĭhildren with ADHD are generally described to have difficulties ignoring irrelevant information, being easily distracted by other stimuli. In its pure form, however, it is conceptualized as a deficit in the processing of auditory input (Children Jerger and Musiek, 2000).Ĭentral auditory processing disorders (CAPD) and ADHD have become popular diagnostic entities for school-age children. It may be associated with difficulties in listening, speech understanding, language development, and learning. Auditory processing disorder (APD) may be broadly defined as a deficit in the processing of information that is specific to the auditory modality. The main symptoms of ADHD are inattention, hyperactivity, and impulsive behavior (American Psychiatric Association, 1994). Available from: Īttention deficit-hyperactivity disorder (ADHD) affects about 3–5% of children. Central auditory processing and audio-vocal psycholinguistic abilities in children with attention deficit-hyperactivity disorder.

Keywords: attention deficit-hyperactivity disorder, auditory P300, psycholinguistic abilities There was a CAPD in ADHD children as indicated by decreased amplitude of P300 and prolonged latency in such children. This difference was obvious in older children for the Illinois test, but was not observed in P300 results. This study found a significant difference in P300 latency, amplitude, and most of the audio-vocal subtests between the patients and the controls. and 39 normal children were included in the study and were subjected to P300 ERP, audio-vocal items of Illinois test of psycholinguistic abilities. Participants and methodsįorty children with a diagnosis of ADHD according to Diagnostic and Statistical Manual of Mental Disorders, 4th ed. P300 (P3) event-related potential (ERP) putatively reflects central auditory dysfunctions associated with ADHD. Central auditory processing disorders and attention deficit-hyperactivity disorders (ADHD) have become popular diagnostic entities for school-age children.
