What are the symptoms of Behcet's disease ? 

What are the signs and symptoms of Behcet's disease? Symptoms of Behcet's disease include recurrent ulcers in the mouth (resembling canker sores) and on the genitals, and eye inflammation (uveitis). The disorder may also cause various types of skin lesions, arthritis, bowel inflammation, meningitis (inflammation of the membranes of the brain and spinal cord), and cranial nerve palsies. Behcet's is a multi-system disease; it may involve all organs and affect the central nervous system, causing memory loss and impaired speech, balance, and movement. The effects of the disease may include blindness, stroke, swelling of the spinal cord, and intestinal complications. The Human Phenotype Ontology provides the following list of signs and symptoms for Behcet's disease. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
