Central nervous system (CNS) involvement in patients with lupus remains both a diagnostic and a therapeutic challenge. The role of autoantibodies in the pathogenesis of CNS lupus and/or as markers for disease activity is reviewed. Doubt is cast on the value of measuring anti-neuronal antibodies. Those antibodies binding ribosomal-P protein antigens or certain phospholipids appear to have greater utility, although even in these cases there is no uniform agreement as to their precise role in CNS disease induction, or how well antibody levels reflect disease activity.
