Neuro-Behçet's disease

Behçet's disease is recognized as a disease that cause inflammatory perivasculitis, inflammation of the tissue around a blood or lymph vessel, in practically any tissue in the body. Usually, prevalent symptoms include canker sores or ulcers in the mouth and on the genitals, and inflammation in parts of the eye. In addition, patients experience severe headache and papulopustular skin lesions as well. The disease was first described in 1937 by a Turkish dermatologist, Dr. Hulusi Behçet. Behçet's disease is most prevalent in the Middle East and the Far East regions; however, it is rare in America regions.The initial signs and symptoms of NBD are usually very general. This makes NBD hard to diagnose until the patients experience a severe neurological damage. In addition, the combination of symptoms varies among patients.Because the cause of Behçet's disease is unknown, the cause responsible for neuro-Behçet's disease is unknown as well. Inflammation starts mainly due to immune system failure. However, no one knows what factors trigger the initiation of auto-immune disease like inflammation. Because the cause is unknown, it is impossible to eliminate or prevent the source that causes the disease. Therefore, treatments are focused on how to suppress the symptoms that hinders daily life activities.Although there is a diagnostic criterion for Behçet's disease, one for neuro-Behçet's disease does not exist. Three diagnostic tools are mainly used.No definite standard treatment have been set. This is because treatments of the disease has been poorly studied as of 2014. Often in cases of inflammatory parenchymal disease, 'corticosteroids should be given as infusions ofintravenous methylprednisolone followed by a slowly tapering course of oral steroids'. It is suggested that therapy should be continued for a period of time even when the symptoms get suppressed because early relapse may occur. Sometimes, the medical doctors may suggest a different steroid depending on the nature of the disease, the severity, and the response to steroids. According to several studies, parenchymal NBD patients successfully suppress the symptoms with the prescribed steroids. As for non-parenchymal patients, there is no general consensus on how to treat the disease. The reason is that the mechanisms of cerebral venous thrombosis in BD are still poorly understood. Some doctors use anti-coagulants to prevent a clot. On the other hand, some doctors only give steroids and immunosuppressants alone.In one study of 387 Behçet's disease (BD) patients that has been done for 20 years, 13% of men with BD developed to NBD and 5.6% of women developed to NBD. Combining all statistical reports, approximately 9.4% (43 of 459) BD patients advanced to NBD. In addition, men were 2.8 times more likely to experience NBD than women. This fact indicates possible gender-based pathology.In speaking about age of NBD patients, the general range was between 20 and 40. NBD patients with age less than 10 or more than 50 were very uncommon.
