Attention deficit/hyperactivity disorder (ADHD) is characterized by inattention, motor hyperactivity, impulsivity, or a combination of all. The P300 is a non-invasive neurophysiological that has shown its effectiveness to detect differences between subjects with ADHD but results are not yet conclusive. To assess brain information processing by the P300 component, auditory, visual and tactile modality in children with ADHD. The P300 components auditory, visual and tactile 17 children with ADHD (11 combined and 7 in-attentive) and 15 control children aged between 7 and 10 years were recorded. In response reaction times found a more pronounced trend in the auditory and visual time but not statistically significant in any of the three responses. In the error rate increased in children with ADHD compared to the control group. Children with ADHD have a significant increase in latency of visual P300 wave while there is no significant decrease in tactile and auditory P300. We found increased cortical areas in the P300 component in children with ADHD during visual and auditory test, but not touch. Our results support the hypothesis of the existence of increased brain areas during auditory and visual sensory processing in ADHD group, except for tactile stimulation happens otherwise.
