title: Neuropsychiatric manifestations of systemic lupus erythematosus.
abstract: Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) can produce a broad range of disease-specific neuropsychiatric manifestations that must be differentiated from infections, metabolic complications, and drug-induced toxicity. Despite the development of classification criteria by the American College of Rheumatology, the prevalence of neuropsychiatric systemic lupus erythematosus (NPSLE) varies widely across studies. Some of the neuropsychiatric manifestations are extremely rare, indicating a need for multicenter studies. Mechanisms that can lead to neuropsychiatric manifestations include intracranial vascular lesions (vasculitis and thrombosis); production of autoantibodies to neuronal antigens, ribosomes, and phospholipids; and inflammation related to local cytokine production. As a rule, no reference standard is available for establishing the diagnosis of NPSLE. Several investigations can be used to assist in the clinical diagnosis and to evaluate severity. Treatment remains largely empirical, given the absence of controlled studies. Variable combinations of corticosteroids, immunosuppressants, and symptomatic drugs are used according to the presumptive main pathogenic mechanism.
