[Neurologic manifestations of Behçet's disease].

Abstract
Neurological involvement in Behçet's disease, the cause of the disease's severe functional sequellae, is reported in 5.3 to 30% of cases. Coagulation disorders have been reported but they cannot explain the different thrombotic manifestations which are probably the consequence of an abnormal response of the vascular endothelial cells. Neurological manifestations include: a) dural sinus thrombosis which can be diagnosed by angio-MRI and whose prognosis is improved with the use of anticoagulants; b) exceptional lesions to arteries supplying the brain; c) aseptic meningitis and meningo-encephalitis; and d) exceptionally, solitary spinal cord involvement and peripheral disease. Neurological involvement can occur early or late after development of skin and mucosal signs and when inaugural make mislead diagnosis. The spinal tap usually gives objective evidence of lymphocyte meningitis. MRI is nonspecific, but the T2 and Flair sequences can evidence hypersignal areas, preferentially in the brain stem, basal nuclei, and subtentorial white matter with no preference for the periventricular regions. Spontaneous aggravation is the rule and the neurological prognosis is severe (dementia, pseudo-bulbar syndrome, loss of independence). Treatment is similar to that used for vasculitis and is aimed initially at reducing the inflammation with corticosteroids and at preventing relapse with the adjunction of an immunosuppressor. Results are better when treatment begins early; restitutio ad integrum has been observed. Duration of treatment is poorly defined: immunosuppressors have been proposed for a minimal duration of 2 years; corticosteroid therapy can be tapered off but interruption would expose to relapse. A maintenance therapy is advisable and, in our opinion, should be proposed indefinitely combining colchicine (1 to 2 mg/d), anti-aggregate doses of aspirin, and low-dose corticosteroids (1/10 mg/kg/d).
