Multicenter Study Observational Study
Clinical factors influencing the impact of cluster headache from a prospective multicenter study.
Although many patients with cluster headaches (CH) are disabled by their condition, few studies have examined this in detail. This cross-sectional, multicenter observational study prospectively collected demographic and clinical questionnaire data from 224 consecutive patients with CH. We assessed headache impact using the six-item Headache Impact Test (HIT-6) and evaluated the factors associated with the impact of CH. ⋯ The anxiety (OR = 1.19, 95% CI: 1.08-1.31, p = 0.006), greater pain intensity (OR = 1.06, 95% CI: 1.02-1.10, p = 0.002), and age (OR = 0.99, 95% CI: 0.99-1.00, p = 0.008) were significant predictors for a severe impact of CH patients. According to the HIT-6 results, most of the CH patients were significantly affected by CH. As well as pain intensity, anxiety and age modulated CH's impact on their lives.
