Researchers continue to dissect all the characteristics of the Covid epidemic which has slowed down the lives of a large part of the world. They are now trying to understand the phenomenon. In any case, they found that after infection with Sars Cov 2, many patients become migraineurs.

Blurred vision, sensitivity to light, noise, nausea, shooting pains that accompany violent headaches, these are the symptoms of migraine.
One in 8 people affected by long Covid would subsequently develop this condition. It could persist for around 6 months. However, most patients who suffer from it say they never had these clinical signs before their covid.
These are most often middle-aged women who have a family history of migraine.
The mechanism explaining the link between SARS Cov 2 infection and these migraines is not yet fully understood by scientists. Proteins essential to the functioning of the immune system could be the cause. Indeed, when an individual is affected by Covid, they generally have inflammation which can affect any organ of the body including the brain.
It is these proteins, the cytokines, which are at the origin when they come into action to defend the human body.
This reaction could therefore be the one that leads to new daily headaches in some patients.
As of January 2021, a preprint from Lopez-Leon’s group identified a total of 55 long-term effects associated with COVID-19 and assessed their prevalence through a systematic review and meta-analyses (See below). below).
The most common were fatigue, headache, attention deficit, hair loss and dyspnea. Collectively, long COVID is linked to a spectrum of symptoms and may appear to affect an increasing proportion of people recovering from COVID-19 worldwide.
Long-term effects of COVID-19. This figure, adapted from a meta-analysis by Lopez-Leon et al., displays the percentage of each long-term COVID-19 symptom. Symptoms are divided into General, Brain, and Heart and Lungs categories. Fatigue, headache, attention deficit disorder, hair loss and shortness of breath were the most common. • ©Lopez-Leon et al.
But long Covid causes many other symptoms. For researchers, it is therefore important to adopt a multidisciplinary approach to understand the phenomenon.
