Objective To investigate the features of brainstem auditoryresponses (BAR) in patients with attention deficit and hyperactive disorder (ADHD), mental retardation and conduct disorder. Methods BAR in children with ADHD ( n =37), mental retardation (MR, n =24) and conduct disorder (CD, n =22), and in normal children ( n =30) were measured by use of Nicolet Spirit electrophysiological instrument delivering stimulation of Clicks. Results The absolute latencies (AL) of wave Ⅲ、Ⅴ recorded from Fz region (WⅢ、Ⅴ/Fz) and wave Ⅲ from Pz region (WⅢ/Pz) as well as the absolute amplitudes (AA) of WⅢ/Fz and WⅤ/Pz were significantly different ( P
