Many studies presented the relation between children and adolescent with behavioral disorders and EEG changes and auditory event related potential (P300). This research was designed to study neurophysiological changes and intelligence associated with conduct disorder. P300 and EEG were done for 45 students with conduct disorder (CD) from different secondary schools in Assiut City and 45 normal students as a control group from the same schools. While Wechsler Intelligence Scale (WIS) was done for 101 students with CD and 100 normal students as a control group. The results of this study revealed that P300 amplitude is significantly lower in students with CD than control group. The commonest paroxysmal activity in EEG was spike and slow complex (55.5%), followed by sharp activity (28.9%). The background activity was significantly lower in students with CD than control group. CD students had significantly lower total and  performance IQ than control group, while no significant difference as regard  verbal IQ. These changes may suggest the presence of subtle anterior brain dysfunction among CD.
