Migraine is one of the most disabling diseases worldwide, especially when it transforms into chronic migraine, which is often associated with medication overuse and can become resistant or even refractory to treatments. Molecular, neuroimaging and neurophysiological changes have been described in chronic migraine, some of which might not be fully reversible with preventive treatment. For these reasons, we should aim to prevent this transition, and initiate preventive treatment before disease becomes refractory and burden increases. Preventive migraine treatments are often delayed because of access to care, stigma leading to undertreatment and patients' reluctance as a result of fear of side effects and, in some cases, fear of being labeled as chronically ill. With the availability of effective and well-tolerated preventive treatments, we must shift our mindset and take advantage of new opportunities to initiate preventive treatment earlier. In this International Headache Society position statement, we propose a migraine preventive strategy under the idea of shifting from reactive treatment once disability is established (prevention of attacks), to proactive, individualized prevention initiated early with safe, effective and tolerable therapies (prevention of disease progression). This approach is based on 1) promoting the early initiation of effective and tolerable preventive therapies, starting from two to four monthly migraine days in line with the majority of current guidelines and recommendations and 2) fostering longitudinal studies to gather more evidence on the potential benefit of early prevention, with the final goal of improving patient outcomes, promoting excellent migraine care, enhancing individual and social well-being, and, ultimately, preventing migraine progression and preserving brain health.
