Neuropsychiatric syndromes in patients with systemic lupus erythematosus and rheumatoid arthritis.

Abstract

NP syndromes, regardless of etiology, are common in both SLE and RA patients. SLE patients with NP syndromes report more symptoms of depression and cognitive dysfunction compared to RA patients with NP syndromes, but do not report significantly poorer HRQOL. These results emphasize the presence of non-disease-specific causes of NP manifestations in SLE patients, which should be acknowledged in future studies of pathogenesis and treatment.
