Objective

Central auditory processing disorders and attention deficit-hyperactivity disorders (ADHD) have become popular diagnostic entities for school-age children. P300 (P3) event-related potential (ERP) putatively reflects central auditory dysfunctions associated with ADHD.

Participants and methods

Forty children with a diagnosis of ADHD according to Diagnostic and Statistical Manual of Mental Disorders, 4th ed. and 39 normal children were included in the study and were subjected to P300 ERP, audio-vocal items of Illinois test of psycholinguistic abilities.

Results

This study found a significant difference in P300 latency, amplitude, and most of the audio-vocal subtests between the patients and the controls. This difference was obvious in older children for the Illinois test, but was not observed in P300 results.

Conclusion

There was a CAPD in ADHD children as indicated by decreased amplitude of P300 and prolonged latency in such children.
