Evoked potential studies including BAEP (Brainstem Auditory Evoked Potential), VEP (Visual Evoked Potential) and SEP (Somatosensory Evoked Potential-median nerve stimulated at wrist) were performed in 6 patients of wilson disease. Four patients with advanced neurological symptoms showed abnormal BAEP, revealing delayed latency for wave V, with prologation of interpeak latency between wave I and wave V, sepecially between III and V. However, two with only mild symptoms or without neurologic involvement showed normal BAEP. SEP and VEP studies were taken in 5 cases; SEP showed abnormal central conduction in one case and no cases were abnormal in VEP.
