Clinical characteristics of 2378 patients presenting with headache disorders to headache clinics in Japan: A clinic-based multicenter study
Abstract
BACKGROUND: There are reports from single-center studies on patients visiting headache clinics; however, few multicenter studies have been conducted in Japan. This study aims to address this gap by conducting a multicenter analysis of the clinical characteristics, headache types, severity, and psychiatric comorbidities of patients attending headache clinics.
METHODS: We prospectively evaluated the clinical characteristics of 2378 patients with headache disorders visiting three headache clinics. Baseline demographics, such as the visual analog scale (VAS), and psychiatric assessments, such as the Generalized Anxiety Disorder-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), were evaluated. Headache types were classified as migraine, tension-type headache (TTH), trigeminal autonomic cephalalgias (TACs), other primary headache disorders (OPHDs), and secondary headache. Parameters were compared between headache types using the Kruskal-Wallis test or analysis of covariance, as appropriate.
RESULTS: The most common headache type was migraine (78.8 %), followed by TTH (12.2 %), secondary headache (5.5 %), OPHDs (2.1 %), and TACs (1.6 %). Patients with migraine were significantly younger at first consultation (median age 32.0) than those with other headache types (TTH; 47.0, TACs; 39.0, OPHDs; 49.5, and secondary headache; 47.0). Patients with TACs exhibited the highest severity and psychiatric symptoms, with VAS (median 90.0), GAD-7 (7.0), and PHQ-9 (7.5) scores…
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. Reported size: 2,378 participants or records.
