Abstract
Clinical scales and neuroimaging are used to monitor nervous system injury in Wilson's disease, while data on serum markers are scarce. To investigate whether serum concentrations of neurofilament light chain (sNfL) correlate with brain injury in Wilson's disease patients. In 61 treatment-naïve patients, the Unified Wilson's Disease Rating Scale and a validated semiquantitative brain magnetic resonance imaging scale were compared with concentrations of sNfL. Concentrations of sNfL were significantly higher in patients with neurological disease compared with patients presenting with other forms (39.7 ± 73.4pg/mL vs. 13.3 ± 9.2pg/mL; P < 0.01). Moreover, the sNfL concentration positively correlated with neurological severity scores and with acute and chronic brain damage based on the neuroimaging scale. Neurofilament light chain concentrations may be used as a marker of brain injury in Wilson's disease, in addition to the clinical and neuroimaging disease severity scales. © 2022 International Parkinson and Movement Disorder Society.
