Diagnostic Value of Integrated Visual-Auditory Continuous Performance Test and P300 Event-Related Potentials in ADHD

This prospective study compared P300 event-related potentials and integrated visual-auditory continuous performance test (IVA-CPT) scores between 30 ADHD patients and 30 healthy controls, finding ADHD patients had longer P300 latency, lower amplitude, and lower IVA-CPT scores. Receiver operating characteristic analysis demonstrated both measures had high accuracy for identifying ADHD across subtypes, with significant positive correlation between P300 and IVA-CPT performance.
