Intractable headaches, the so-called `lupus headaches', have been long thought of as a common and characteristic manifestation of systemic lupus erythematosus (SLE). Seventy-eight patients with SLE, including 10 patients with definite central nervous system (CNS) involvement, and 89 healthy individuals matched for age, sex and socioeconomic status, were studied by a specific questionnaire addressing the characteristics and type of headache. Clinical features of SLE, neurological manifestations and treatment, disease severity and autoantibody profiles were correlated to the presence of headache. One year prevalence of headache was similar between patients (32%) and otherwise healthy individuals (30%). No significant differences regarding frequency, family history of headache and need for analgesic medication were observed. Headache refractory to analgesic treatment, but responsive to corticosteroid regimen, was recorded in only one patient. Clinical and serological features of SLE, including Raynaud's phenomenon and the presence of andicardiolipin antibodies, were not significantly different between headache sufferers and non-sufferers. In the majority of patients reporting headache, anxiety and/or depression co-existed. Episodic tension headache was the most frequent type, while migraine was traced in a quarter of headache sufferers. Neither the presence nor the clinical type of headache was related to, or predictive of, the development of seizures or psychosis. These results indicate that headache is not specifically related to SLE expression or severity, and suggest that accepting the presence even of a severe headache as a neurological manifestation of SLE in the absence of seizures or overt psychosis may result in overestimation of the disease status.
