Headache in Behçet's syndrome
Abstract
OBJECTIVE: To study the frequencies and characteristics of different headache types seen in patients with Behçet's syndrome (BS) in a large cohort of patients.
BACKGROUND: Patients with BS may present with different neurological problems, related either directly or indirectly to the disease, with headache being the most common neurological symptom seen in this syndrome, as well as independent from neurologic involvement.
METHOD: This study was carried out at the multidisciplinary Behçet outpatient clinic of the Behçet's Syndrome Research Center. Every fifth admitted patient who had fulfilled the International Study Group for Behçet's Disease classification criteria was recruited for this study. Each patient was interviewed by one of the examining neurologists through a semistructured questionnaire. In case of the presence of more than one headache type, the best defined one was diagnosed and evaluated. All patients received a complete neurological and physical examination. A chi(2) test was used to evaluate the differences between frequencies. One sample t-test was used to compare means. The prevalence rates of primary headaches were compared with results of the Turkish Headache Epidemiology study by using goodness-of-fit test.
RESULTS: Two hundred and twenty-eight patients were studied. Headache was reported in 66.2% (151/228) of the study cohort. Primary headaches were seen in 38.6% of the patient population, which corresponds to 58% of BS patients with any type of…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
