How is central nervous system vasculitis treated?
CNS vasculitis is usually treated with steroids. High-dose steroids such as prednisone, in combination with cyclophosphamide (a medication that decreases the immune system's response to autoimmune diseases), are generally used. In some cases, high-dose steroids alone are tried first; if that does not treat the disease, cyclophosphamide is added. Treatment must be continued for a prolonged period, sometimes for life.
If the patient has another illness (such as lupus) that is related to the vasculitis, then that illness also needs to be treated.
