Brain imagery reveals that the electrophysiological changes seen during an attack become permanent in people with chronic migraine; "thus, from an electrophysiological point of view, chronic migraine indeed resembles a never-ending migraine attack." Severe migraine ranks in the highest category of disability, according to the World Health Organization, which uses objective metrics to determine disability burden for the authoritative annual Global Burden of Disease report. The report classifies severe migraine alongside severe depression, active psychosis, quadriplegia, and terminal-stage cancer.[3]
Migraine with aura appears to be a risk factor for ischemic stroke[4] doubling the risk.[5] Being a young adult, being female, using hormonal birth control, and smoking further increases this risk. There also appears to be an association with cervical artery dissection.[6] Migraine without aura does not appear to be a factor.[7] The relationship with heart problems is inconclusive with a single study supporting an association. Migraine does not appear to increase the risk of death from stroke or heart disease.[8] Preventative therapy of migraines in those with migraine with aura may prevent associated strokes.[9] People with migraine, particularly women, may develop higher than average numbers of white matter brain lesions of unclear significance.[10]

- QUOTE: Erenumab is a fully human monoclonal antibody that inhibits the canonical calcitonin gene-related peptide (CGRP) receptor[1]. Clinical studies have demonstrated the efficacy and safety of erenumab in patients with episodic migraine (EM)[2] [3] and chronic migraine (CM)[4] including in those with prior preventive migraine treatment failures[5][6]. Results from the Phase 3b LIBERTY study confirmed that erenumab is a potential treatment for the management of patients with EM in whom 2–4 preventives were not useful[7].

- QUOTE: The Migraine Physical Function Impact Diary (MPFID) is a 13-item self-report questionnaire, developed to measure the subjective impact of migraine on physical functioning (everyday activities and physical impairment) in the past 24 hours. It is intended for use in adults (age 18 or older) with episodic migraine (EM) or chronic migraine (CM), with or without aura. The diary was developed using methods consistent with the regulatory guidance on patient-reported outcome (PRO) measures to support label claims about the benefit of treatments.
The MPFID was designed to be completed every day to capture the day-to-day variability of the impact of migraine, on migraine and non-migraine days.
The MPFID was conceptually designed to capture both ‘acts’ and ‘tasks’ associated with the impact of migraine on functioning. The MPFID includes multiple domains to assess the impact of migraine on physical functioning:
