 A score of 8 is given to this item (items are given a relative weight of 1, 2, 4 or 8).The 1999 American College of Rheumatology case definitions of neuropsychiatric syndromes in SLE do not define lupus headache, but rather propose several headache disorders loosely based on the International Headache Society (IHS) classification.In the IHS scheme, headache due to lupus would be classified as "Headache attributed to other non-infectious inflammatory disease" (7.3.3).
