Diagnosis of central nervous system lupus.

Central nervous system (CNS) involvement in systemic lupus erythematosus is a major source of patient morbidity and mortality. The recognition of nervous system lupus is hampered by the diagnostic insensitivity and non-specificity of the various testing modalities that are currently available. A review of the effectiveness of diagnostic tests for CNS lupus is presented. Areas of current research in this area are examined. Because of the diversity of neurologic manifestations in this disorder and their complex pathogenesis, no single test is sufficient to establish the diagnosis rapidly and accurately in all cases, now or for the foreseeable future.
