High prevalence of headaches during Covid‐19 infection: A retrospective cohort study
Headache: The Journal of Head and Face Pain Aug 11, 2020
Poncet‐Megemont L, Paris P, Tronchere A, et al. - In patients with coronavirus disease 2019 (Covid‐19) infection, researchers conducted this retrospective cohort study to record how prevalent new headaches are and if they are associated with other neuro‐sensorial symptoms (anosmia and ageusia). In addition, whether these symptoms persisted 1 month after recovery was noted. All patients with laboratory-confirmed or chest-CT-confirmed Covid‐19 infection, diagnosed between February 27 and April 15, 2020 in the dedicated Clermont‐Ferrand University Hospital laboratory were followed up for 1 month after their recovery. One month after fever and dyspnea had vanished, 139 consecutive patients (mean [SD] age, 48.5 [15.3] years; 87 women [62.6%]) were interviewed (semi‐structured phone interview). New headaches during the acute phase were reported in 59.0% of these patients, with 3.6% reporting persistent headaches 1 month following fever and dyspnea remission. Anosmia was reported in in 60.4% of patients and ageusia was reported in 58.3% of patients, and they persisted at 1 month after recovery in 14.4% and 11.5% of Covid‐19 patients, respectively. Neither of these nor severity of disease were clearly correlated with headaches. To refine the characterization of patients with Covid‐19‐associated headaches, further studies are required.
