RESUMO
Neuropsychiatric systemic lupus erythematosus (NPSLE) involves a wide range of focal and diffuse central and peripheral nervous system disorders and affects up to 75% of SLE patients. NPSLE can occur any time in the course of SLE, even during periods in which no SLE disease activity is detected, and is likely to be caused by multiple factors, including autoantibody production, microvasculopathy and pro-inflammatory cytokines. Central to the diagnosis of NPSLE is the question of whether the presenting neuropsychiatric symptoms are due to SLE-mediated organ dysfunction, infection, medication side-effects or metabolic abnormalities (e.g. uraemia), or are due to an unrelated condition. The diagnostic inference of NPSLE can be made only after these secondary causes have been excluded. There is no one single diagnostic tool specific to NPSLE, and clinical diagnostic impressions must be based on the combined use of immunoserological testing, functional and/or structural neuroimaging and standardized neurological, rheumatological, psychiatric and neuropsychological assessments. The management of NPSLE includes symptomatic and/or immunosuppressive treatment strategies depending on the specific presenting neuropsychiatric symptoms and whether these occur in the setting of an SLE disease activity flare.

Verbal material used to assess the cognitive abilities of Spanish-speakers in the the United States is frequently of linguistically unacceptable quality. The use of these materials in research settings is thought to pose a serious threat to test validity and hence to the validity of claimed results or conclusions. The authors explain how and why incorrect language finds its way into cognitive tests used in research and other settings and suggest solutions to this serious problem.

The correct diagnosis of central and peripheral nervous system manifestations in patients with systemic lupus erythematosus (SLE) can be challenging because of many SLE-related and non-SLE-related processes that can be present in a patient. The American College of Rheumatology (ACR) has published case definitions for 19 neuropsychiatric SLE (NPSLE) syndromes, with careful attention to important exclusion criteria. These criteria were developed for research purposes but can be helpful to clinicians with a patient who has nervous system dysfunction. This report reviews the data regarding the application of the ACR NPSLE criteria and the influence of ethnicity and disease duration on the development of NPSLE syndromes. Cognitive dysfunction and psychiatric disorders are the two most common manifestations. The work-up and treatment of nervous system syndromes are also discussed.
