**6.1 Behcet's disease**

Initially described in 1937, the disease is well known for causing oral and genital aphthous lesions, along with uveitis. Gradually, it became clear that the patients may experience ulcerations in other parts of the gastrointestinal tract, like esophagus [64]. But this local pathology is not the sole cause of dysphagia in this disease. CNS involvement in Behcet's disease is an established neuroinflammatory pathology. The parenchymal involvement has a significant predilection to the brainstem so dysphagia is expected. Vascular pathologies of the CNS could affect successful swallowing, as well [65, 66]**.**
