Introduction
Migraine is one of the most disabling neurological diseases and is aggravated by anxiety, stress, and sleep dysfunction. Recent studies have shown worsening of migraine associated with the COVID-19 infection and the pandemic more broadly. COVID-19 vaccination has also been associated with symptomatic headache, with high frequency among migraineurs. We aim to assess the impact of COVID-19 diagnosis and vaccine administration on migraine, during the SARS-CoV-2 pandemic.
Methods
An online questionnaire was sent to migraine patients followed in a neurology outpatient clinic. The survey inquired about migraine symptoms and treatment changes, as well as sleep changes, anxiety and depressive symptoms during the pandemic, after a COVID-19 diagnosis and/or vaccination.
Results
Out of the 185 patients included, 108 (58.4%) reported a change in headache pattern (42% before a COVID-19 diagnosis) and 72.2% needed to escalate treatment during the pandemic, regardless of infection. Migraine worsening was associated with higher rates of persistent symptomatic headache. A change in sleep pattern was more frequently reported in migraineurs after COVID-19 and in the group with worsening migraine. Abnormal levels of anxiety and depression were high among patients with worsening migraine, irrespective of COVID-19 diagnosis. After vaccination, 49 (27.1%) described a change in headache pattern, with worsening pattern in 29 (16%), 48% up to 3 weeks.
Conclusion
Worsening of migraine was more likely associated to psychosocial factors related to the pandemic rather than COVID-19 diagnosis per se. COVID-19 vaccination might have acted as an additional but less relevant and temporary trigger for migraine worsening.
