ABSTRACT
This study explored the association between headache response and return to functioning, and identified migraine-associated symptoms related to functional status and acceptability of migraine treatment as reported by patients. Data from migraineurs enrolled in the active arms of a randomized, double-blind, parallel group, placebo-controlled, clinical trial were analysed. The relationships between headache response and functional response, and clinical factors and treatment acceptability were assessed using chi(2) tests of proportions and logistic regressions. A greater proportion of patients with headache response at 0.5 h were functioning at 0.5, 1 and 2 h compared with patients who did not attain a headache response at 0.5 h (P < 0.0001). These patients also were more likely to find their treatment acceptable (P < 0.05). The results suggest a direct temporal relationship among the key determinants of migraine resolution. Rapid headache response is associated with faster return to functioning; rapid headache and functional responses are significant attributes of treatment acceptability.
