Chronic migraine refers to migraine headaches occurring at least 15 days per month, frequently associated with significant functional impairment and depression.
Outcomes of Treatment in Chronic Migraine Patients (N = 784)
2022
GAD-7 = Generalized Anxiety Disorder Questionnaire, HIT-6 = Headache Impact Test, PHQ-9 = Patient Health Questionnaire, PROMIS = Patient Reported Outcome Measurement Information System.
In 2022, 784 patients with chronic migraine completed at least 1 questionnaire following treatment. Of the 267 patients who reported HIT-6 scores > 50 at initial evaluation (higher scores indicate greater impairment secondary to headache pain¹), 91% reported improvement or remained stable. The PROMIS is a self-reported measure of physical and emotional health status reflecting health-related quality of life.² Of the 517 patients who reported initial PROMIS global health more than one-half standard deviation below the normative mean, 93% improved or remained stable. Of the 315 patients who reported initial depressive symptoms above the cutoff of ≥ 10 points for the PHQ-9 (higher scores indicate greater depression³), 97% remained improved or stable at follow-up. Of the 198 patients who reported initial anxiety symptoms above the cutoff of ≥ 10 points for the GAD-7,⁴ 97% remained improved or stable at follow-up.
