Fernández-de-las-Peñas C, Navarro-Santana M, Gómez-Mayordomo V, et al. - According to this meta-analysis, the prevalence of post-COVID headache ranged from 8 to 15% during the first six months after SARS-CoV-2 infection.

• There were 28 peer-reviewed studies and 7 preprints among the 9,573 studies found.

• The sample consisted of 28,438 COVID-19 survivors (12,307 females; mean age: 46.6, SD: 17.45 years).

• The overall prevalence of post-COVID headache was 47.1% at the time of 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 after onset/hospital discharge.

• Headache was more common in non-hospitalized patients than in hospitalized patients during the acute phase.

• Time trend analysis revealed a reduction in prevalence from the onset of the acute symptom to all post-COVID follow-up periods, which was sustained after.
