Over the past three years, the worsening of migraine episodes may have been associated with contamination by Covid-19 or the vaccine. However, a recent study carried out on the subject confirms the very thin correlation between these two points. Explanations.
According to Spanish researchers*, Covid-19 and the vaccine against this coronavirus have little effect on migraine. Thus, according to a study carried out among 550 patients followed for an episode of migraine, 247 of them had contracted Covid-19 once. And 458 were vaccinated.
Result: 61 patients (24.7%) reported a worsening of their migraine since their contamination and 52 (11.4%) since their vaccination. Increasing their worries related to their headaches.
But it seems that this is just a perception. Because when investigators looked at information from patients’ electronic diaries, they observed no significant differences in headache frequency one month before and after infection or vaccination
Reassure patients
« In the case of COVID-19, we have previously reported that headaches are a common and disabling symptom of the infection, yet this is not necessarily linked to an increase in migraine frequency », Describes Professor Melgarejo. “ In light of our results, we believe that clinicians should convey a more reassuring message to patients that COVID-19 and COVID-19 vaccines may have a marginal effect on the course of migraine. This information can help minimize their worry. »
