OBJECTIVE: The aim of the present study was to analyze demographic, clinical and genetic features of Behçet's disease patients with neurological involvement through a monocentric study of a homogenous group of hospitalized patients observed in the same department and to compare them with those of other ethnic and geographic groups. METHODS: Four hundred and thirty Behçet's disease (BD) patients were retrospectively studied. Diagnosis of BD was made according to the international study group for Behçet's disease criteria. Patients with neurological findings suggestive of involvement of the nervous system by BD were further studied according to clinical examination, laboratory tests and neuroradiological investigations. RESULTS: Neurological involvement was observed in 121 patients (28.1%). The mean age at neuro-Behçet's disease (NBD) onset was 29.7 years. Average disease duration of BD before neurological manifestations onset was 6.4 years. Male to female ratio was 1.8. Of the 121 NBD patients, parenchymal involvement occurred in 74 patients (61%). Among them 26 (21.4%) presented with brainstem involvement, 24 (19.8%) with hemispheric involvement and 2 (1.6%) with spinal cord involvement. Non-parenchymal NBD occurred in 47 patients (39%). Involvement of the main vascular structures (Vasculo-NBD) was the most common non-parenchymal NBD lesion found in 35 patients (28.9%) consisting of cerebral vein thrombosis (CVT) in 24 cases and cerebral arterial thrombosis in 11 cases. Forty-nine (40.5%) patients with NBD have been followed-up for a median of 3 years (range 1-19 years). Forty-one of them recovered well without significant residual disability, 5 patients made no improvement and are left with severe neurological impairments and 3 died. Male gender and CNS parenchymal lesions occurrence were significantly associated with a poorer prognosis. CONCLUSION: Clinical and epidemiological features of NBD are various. In our Tunisian cohort of NBD patients the main characteristic features were male predominance, a relatively high prevalence of CVT, a low prevalence of intra-cranial hypertension and a significant lower frequency of HLA-B51 haplotype.
