Abstract
We studied the sensory evoked potentials in pediatric Wilson disease to verify their subclinical neurologic involvement and to elucidate the role of cirrhosis in abnormal evoked potentials in non-neurologic Wilson disease. Thirty children (17 male, 13 female), diagnosed with Wilson disease before 18 years, were enrolled. The mean age during studies was 15.8 ± 6.3 years, and disease duration since diagnosis was 3.0 ± 3.3 years. In 12 neurologic Wilson disease cases, there were prolonged interpeak latencies of brainstem auditory evoked potentials III-V, I-V, somatosensory evoked potentials N13-N20 (P < 0.01 vs controls and non-neurologic cases), and P100 latency (P < 0.01 vs controls). All 12 patients had at least one abnormal evoked potential, including 91.7% brainstem auditory, 58.3% somatosensory, and 25% visual evoked potentials. In 18 non-neurologic Wilson disease cases, there were still prolonged interpeak latencies for brainstem auditory evoked potentials I-V and somatosensory evoked potentials N13-N20 (P < 0.05 vs controls), with 27.8% of them having at least one abnormal evoked potential, including 16.6% brainstem auditory, 5.6% somatosensory, and 11.1% visual evoked potentials. In those with non-neurologic Wilson disease, there were no significant differences in all the evoked potential parameters between the cirrhotic and non-cirrhotic patients. ? 2003 by Elsevier Inc.
