ABSTRACT
The worldwide treatment gap for migraine before COVID-19 inevitably widens as attention focuses on an international emergency. Migraine hits people particularly in their early and middle years, potentially reduces quality of life and productivity, and remains a common emergency presentation. This article examines the impact of COVID-19 on migraine, and changing aspects of migraine care during and after the pandemic. Many risk factors for severe COVID-19-older age, male gender, cardiac and respiratory diseases, diabetes, obesity, and immunosuppression-are less frequent in migraineurs. Telemedicine is effective for migraine follow-up, and needs ongoing evaluation. Most migraine treatments can start or continue in acute COVID-19, with care to avoid drug interactions. Close contact procedures (botulinum toxin, acupuncture and steroid injections) are avoided in lockdown or in the vulnerable. Secondary effects of COVID-19, including long COVID and its economic impact, are probably equal or greater in people with migraine. Migraine and other long-term conditions need adequate resourcing to prevent personal, social and economic suffering. Treating migraine, a sequel of COVID, potentially reduces the impact of long COVID.
