title: [Neurological or psychiatric symptoms in patients with systemic lupus erythematosus (SLE): terminological problems, pathogenesis, diagnosis and therapy].
abstract: The nomenclature of the American College of Rheumatology leads to misunderstandings in multidisciplinary discussions on patients with systemic lupus erythematosus (SLE) who also have neurological or psychiatric symptoms. These proposed neuropsychiatric syndromes are rarely syndromes and the symptoms are rarely neuropsychiatric. It is better first of all to determine whether the SLE patients have neurological or psychiatric symptoms, and if these symptoms are present, the first question is what is the cause. Vasculitis of the cerebral blood vessels should be considered as a possible explanation only if ischaemic lesions in the brain have been demonstrated, other causes of cerebral ischaemia in SLE are unlikely, and the clinical signs are consistent with cerebral vasculitis. These other causes of cerebral ischaemia include: antiphospholipid antibodies, atherosclerosis, heart valve disorders and thrombotic thrombocytopenic purpura.
