Toward a better understanding of persistent headache after mild COVID-19: Three migraine-like yet distinct scenarios

One year after the outbreak of coronavirus disease 2019 (COVID-19), referrals for persistent headache, often defined as post-COVID headache, have become increasingly common in outpatient headache clinics. However, it is important to take into consideration that this term may include a spectrum of clinically different headache types. We describe three cases of migraine-like headaches in individuals with a history of mild COVID-19 infection to demonstrate some of the different phenotypes of persistent headaches seen. These cases highlight the importance of a careful evaluation when assessing the complexities of post-COVID headache as well as the need to further investigate the different, underlying, pathophysiological mechanisms.
