This study analyzed the prevalence of post-COVID headache in COVID-19 survivors, finding that the prevalence of headache was around 47.1% at onset or hospital admission, 10.2% at 30 days, 16.5% at 60 days, 10.6% at 90 days, and 8.4% at >=180 days. Headache as a symptom at the acute phase was more prevalent in non-hospitalized patients compared to hospitalized patients.
Background Headache is identified as a common post-COVID sequela experienced by COVID-19 survivors. The aim of this pooled analysis was to synthesize the prevalence of post-COVID headache in hospitalized and non-hospitalized patients recovering from SARS-CoV-2 infection. Methods MEDLINE, CINAHL, PubMed, EMBASE, and Web of Science databases, as well as medRxiv and bioRxiv preprint servers, were searched up to 31 May 2021. Studies or preprints providing data on post-COVID headache were included. The methodological quality of the studies was assessed using the Newcastle-Ottawa Scale. Random effects models were used for meta-analytical pooled prevalence of post-COVID headache. Data synthesis was categorized at hospital admission/symptoms' onset, and at 30, 60, 90, and >= 180 days afterwards. Results From 9573 studies identified, 28 peer-reviewed studies and 7 preprints were included. The sample was 28,438 COVID-19 survivors (12,307 females; mean age: 46.6, SD: 17.45 years). The methodological quality was high in 45% of the studies. The overall prevalence of post-COVID headache was 47.1% (95% CI 35.8-58.6) at onset or hospital admission, 10.2% (95% CI 5.4-18.5) at 30 days, 16.5% (95% CI 5.6-39.7) at 60 days, 10.6% (95% CI 4.7-22.3) at 90 days, and 8.4% (95% CI 4.6-14.8) at >= 180 days after onset/hospital discharge. Headache as a symptom at the acute phase was more prevalent in non-hospitalized (57.97%) than in hospitalized (31.11%) patients. Time trend analysis showed a decreased prevalence from the acute symptoms' onset to all post-COVID follow-up periods which was maintained afterwards. Conclusion This meta-analysis found that the prevalence of post-COVID headache ranged from 8% to 15% during the first 6 months after SARS-CoV-2 infection.
