Predictors of clinical outcome and radiologic progression in patients with neuropsychiatric manifestations of systemic lupus erythematosus.

Purpose: We sought to identify the predictors of clinical outcome and of the evolution of cerebral abnormalities in patients with neuropsychiatric systemic lupus erythematosus (SLE).

Subjects And Methods: Thirty-two patients with SLE (including 14 with the antiphospholipid syndrome) who had been hospitalized with primary neuropsychiatric disease were observed prospectively for at least 2 years.
