Neuropsychiatric Lupus

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Involvement of the nervous system, either primary or secondary, is common in SLE, and 19 different neuropsychiatric clinical syndromes have been recognised in association with the disease. Several pathophysiological mechanisms have been implicated in the pathogenesis of neuropsychiatric SLE (NPSLE), including vasculopathy, autoantibodies, and cytokine-mediated tissue injury. Careful evaluation of the patient is required to rule out secondary causes before attributing the neurological symptoms to SLE. Treatment depends on the nature and severity of NPSLE syndrome.
