The association between COVID-19 and headache was made in 2020. COVID-19 associated headache may be caused by the SARS-CoV-2 virus. There is no established system for the classification of COVID-19 associated headache. The exact pathogenesis of headache in COVID-19 patients is not fully understood. It is thought that headache is the result of cytokine release, direct invasion, metabolic disturbances, inflammation, dehydration, and hypoxia. COVID-19-associated headache must be differentiated from other diseases that cause headache, such as migraine, tension-type headache, cluster headache, seizure, meningitis, encephalitis, neurosyphilis, SAH, subdural hematoma, brain tumor, hypertensive encephalopathy, brain abscess, multiple sclerosis, hemorrhagic stroke, Wernickes encephalopathy, and drug toxicity. A positive history of fever and cough in addition to headache is suggestive of COVID-19-associated headache.
- The association between COVID-19 and headache was made in December, 2019 during the SARS-CoV-2 outbreak initiated in Wuhan, Hubei Province, China.
- There is no established system for the classification of COVID-19 associated headache.
- The exact pathogenesis of headache in COVID 19 patients is not fully understood.
- It is thought that headache is the result of:
- Cytokine release
- There is higher concentration on IL-6 and INF-gamma in patients infected with SARS/ CoV2.
- Cytokines can disrupt blood brain barrier and cause tissue injury and cerebral edema.
- Direct invasion
- Metabolic disturbances
- Cytokine release
- COVID-19 associated headache may be caused by SARS-CoV-2 virus.

Epidemiology and Demographics
Incidence / Prevalence
- WHO reported that more than 462,801 people have been infected worldwide, more than 380,723 of which are outside of China.
- The incidence/prevalence of COVID-19-associated headache is still unknown.
- Guan et al. recently reported 13 percent of COVID-19-associated headache among 1099 laboratory-confirmed cases.
- There is insufficient information regarding age-specific prevalence or incidence of COVID-19-associated headache.
- There is insufficient information regarding gender-specific prevalence or incidence of COVID-19-associated headache.
- There is insufficient information regarding race-specific prevalence or incidence of COVID-19-associated headache.
- There are no established risk factors for COVID-19-associated headache.
Natural History, Complications, and Prognosis
- At this point, the natural history of COVID-19-associated headache is unknown.
- Further studies are needed to better understand the COVID-19-associated headache.
- Patients with a history migraine may experience headache as their first symptom, and these patients experience more severe headache and are more disabled by the infection compared with age‐matched cohorts.
- Further studies are needed to better understand complications.
- Larger retrospective studies are needed for evaluating the experience of COVID‐19 in patients with a history of a primary headache disorder.
Diagnostic Study of Choice
- There are no established criteria for the diagnosis of COVID-19-associated headache.
History and Symptoms
- The hallmark of COVID-19-associated headache is headache.
- A positive history of fever and cough in addition to headache is suggestive of COVID-19-associated headache.
- Common symptoms of COVID-19-associated headache are:
- Shortness of breath
- Cognitive impairment
Less Common Symptoms
- Less common symptoms of COVID-19-associated headache are:
- Patients with COVID-19-associated headache usually appear normal.
- Physical examination of patients with COVID-19-associated headache is usually remarkable for fever, cough, and malaise.
- Additional diagnostic tests like blood chemistry and urine analysis may be needed to rule out other medical conditions.
- There are no diagnostic laboratory findings associated with COVID-19-associated headache.
Echocardiography or Ultrasound
- There are no echocardiography/ultrasound findings associated with COVID-19-associated headache.
- There are no CT scan findings associated with COVID-19-associated headache.
- There are no MRI findings associated with COVID-19-associated headache.
Other Imaging Findings
- There are no other imaging findings associated with COVID-19-associated headache.
Other Diagnostic Studies
- There are no other diagnostic studies associated with COVID-19-associated headache.
- Medical therapy for COVID-assocaited-headache is still controversial.
- The use of NSAIDs, who received treatment early in the disease causes worsening of COVID-19 symptoms according to some anecdotal evidences.
- In March 11, 2020, Fang et al. reported the hypothesis that ibuprofen (40 mg/kg/dose) can increase the risk of developing severe and fatal COVID-19 since ibuprofen is known to upregulate ACE2 receptors.
- In March 23, 2020, US FDA announced that it is not aware of any evidence that NSAIDs such as ibuprofen could worsen COVID-19.
- The European Medicines Agency and World Health Organization (WHO) have not yet recommended that NSAIDs be avoided.
- Despite this recommendation, as a precautionary measure many providers are avoiding NSAIDs in patients with COVID-19.
- In practice, the decision to continue or stop NSAIDs in patients with COVID-19 is made in collaboration between the treating physician and the patient, after a brief discussion on the limited available evidence.
- More data are needed before broad recommendations are made.
- There are no established measures for the primary prevention of COVID-19 associated headache.
- There are no established measures for the secondary prevention of COVID-19-associated headache.
