COVID-19 related headaches: epidemiology, pathophysiology, impacts, and management.

Purpose Of Review: This is an expert overview of the recent literature on the nature, epidemiology, pathophysiology, impact, and management of COVID-19 related headache, in the acute phase of infection and in post-COVID-19 syndrome.

Recent Findings: Headache is one of the commonest symptoms of COVID-19 during acute infection and it is often experienced by individuals who go on to develop long COVID. There is a higher prevalence of headache in individuals with long COVID who contracted the Delta variant than in those who were infected with the Wuhan or Alpha variants. Headaches related to COVID-19 infection are commoner and may be more intense in women.There are indications that presence of headache might indicate a more benign COVID-19 infection and a better chance of survival. However, the impact of COVID-19 related headache could be substantial leading to poor quality of life in individuals affected. Headache that changes in its nature in terms of frequency and severity should be investigated to exclude cerebrovascular complications. There are promising new therapies for its treatment, but further research is needed.

Summary: The findings of this review can promote a better understanding of COVID-19 related headache and guide clinicians in the management of patients.
