Study for Prevent Chronification Migraine Through Prediction of Response to Treatment With Anti-CGRP Antibodies

The study consists of an initial visit coinciding with the start of treatment, a subsequent visit after 6 months of treatment and finally another after 12 months, coinciding with the end of treatment. In case of worsening after suspension, a clinical visit will be carried out at the time of worsening to evaluate the reintroduction of the drug and in case of reintroduction, a visit will be carried out after 3 months. If patients do not worsen, a visit will be made 6 months after completing treatment. At each visit, demographic and clinical variables will be collected. In addition, 3 blood tests will be performed corresponding to the beginning of treatment, after 6 months and a month and a half from the last infiltration. Likewise, a brain MRI will be obtained prior to the start of treatment. These blood samples and neuroimaging data will be processed for subsequent analysis.
