![]() The advantage of electrophysiological procedures is the ability to scan mental processes in real time without invasion. Throughout the previous 20 years, the psychotic diseases’ biological substrates were investigated using electrophysiology. The Auditory Continuous Performance Test and cortical auditory evoked potentials (CAEPs) are computerized tests developed to measure selected EF skills in children (Marquardt et al., 2018). This is mainly true for executive function (EF) measure tools. The use of new tools for diagnosis, with neurological and psychological evaluation directed toward school-age children, is essential. Major financial costs were placed on many services like education, social, and clinical ones owing to ADHD, and lifetime impairment has occurred in some of them (Sergeant et al., 2002). The disease is manifested by characteristic age-unrelated symptoms of decreased attention, motor restlessness, and impulsive behavior. With an ∼3–7% prevalence and 30–40% adulthood persistence rate, it became an important medical challenge because of its effect on children’s socioeducational life (Polanczyk et al., 2015).

Keywords: ACPT, attention-deficit hyperactivity disorder, P300, Stroop, Wisconsin card sorting test Positive correlations were observed between P300 amplitude and WCST (perseverative error), P300 amplitude and ST results, and N2 latency and DS backward.Ĭonclusion Assessment of CAEPs and P300 in children with ADHD, as well as their correlation with neurocognitive tests (WCST, DS, and ST), is crucial in diagnosis and management. ACPT showed a significant difference between both groups, with higher percentage in control group. A significant difference for P1-N1 amplitude was observed among different components of CAEP, and no significance was observed regarding P2-N2 amplitude. In comparison with the control group, statistical delayed latencies of significance were observed in ADHD between all CAEP components. P300 amplitude and latency were significantly different between the study groups. ADHD group was impaired in digit span backward and ST than control group. Results Children with ADHD had more perseverative responses, more preservative errors, and more failure to maintain set (FMS) than controls in WCST, with a significant difference among study groups. All participants had detailed psychiatric history, intelligence quotient Wechsler intelligence scale for children (WICS), Conners’ parent/teacher rating scale abbreviated form for ADHD, neuropsychological tests (WCST and Stroop), pure tone audiometry, speech audiometry using GSI 61 audiometer, immittance test using interacoustic, and sustained attention test using auditory continuous performance test (ACPT) P300. Patients and methods A prospective cross-sectional study was performed on 103 children, who were divided into two groups: 53 children newly diagnosed with ADHD (according to Diagnostic and statistical manual of mental disorders, 5th ed.), who were drug naïve, and 50 normal control matched for age, sex, educational and social level, and intelligence quotient. The aim of this study was to assess cortical auditory evoked potentials (CAEP) as well as P300 in children with ADHD, and its correlation with neurocognitive tests. ![]() Background Multiple techniques are used for understanding, determining the real pathophysiological process, and treating attention-deficit hyperactivity disorder (ADHD). ![]()
