About this trial
This multicenter, prospective cohort study aims to identify clinical and demographic predictors that influence the success of greater occipital nerve (GON) block in patients with migraine.
Patients will be evaluated at baseline, on each injection day, and at one- and three-month follow-ups. Study parameters include demographics, migraine type and duration, comorbidities, headache characteristics, treatment history, and validated outcome measures such as the Numeric Rating Scale (NRS), Headache Impact Test-6 (HIT-6), and Global Rating of Change (GRoC).
The goal is to establish predictive factors of treatment success in order to optimize patient selection and contribute robust multicenter evidence to individualized migraine management
