Abstract:

MSUD is a complex metabolic disorder that has been associated with central nervous system damage, developmental delays, and neurocognitive deficits. Although liver transplantation provides a metabolic cure for MSUD, changes in cognitive and adaptive functioning following transplantation have not been investigated. In this report, we present data from 14 patients who completed cognitive and adaptive functioning testing pre- and one yr and/or three yr post-liver transplantation. Findings show either no significant change (n = 8) or improvement (n = 5) in IQ scores pre- to post-liver transplantation. Greater variability was observed in adaptive functioning scores, but the majority of patients evidenced no significant change (n = 8) in adaptive scores. In general, findings indicate that liver transplantation minimizes the likelihood of additional central nervous system damage, providing an opportunity for possible stabilization or improvement in neurocognitive functioning.
