Our objective was to explore the prevalence and possible risk factors associated with Bell's palsy recurrence in the Clinical Center of the University of Debrecen service area. Secondary data analysis was performed using hospital discharge data, including patient information and comorbidities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Data was obtained from the Clinical Center of the University of Debrecen, on Bell's palsy patients who were treated at the hospital between January 1, 2015 and December 31, 2021. Multiple logistic regression analysis was used to examine the factors associated with Bell's palsy recurrence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of the 613 patients analyzed, 5.87% had recurrent paralysis, and the median time interval between episodes was 315 days. Hypertension was significantly associated with Bell's palsy recurrence. Moreover, seasonal distribution analysis revealed that the number of Bell's palsy episodes was higher in colder seasons, with spring and winter having a significantly higher number of episodes than summer and autumn.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>This study provides insights into the prevalence and associated risk factors of Bell's palsy recurrence, which could aid in its management and help reduce the long-term consequences of the disease. Further research is necessary to determine the precise mechanisms underlying these findings.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2023.1188137","type":"journal-article","created":{"date-parts":[[2023,6,20]],"date-time":"2023-06-20T10:07:37Z","timestamp":1687255657000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Seasonal patterns in the epidemiology of Bell's palsy in Hungary"],"prefix":"10.3389","volume":"14","author":[{"given":"Eszter","family":"Varga","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ulambayar","family":"Battamir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Istv\u00e1n","family":"Szegedi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilla","family":"Hud\u00e1k","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N\u00f3ra","family":"Kov\u00e1cs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Attila Csaba","family":"Nagy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,6,20]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"845","DOI":"10.1002\/mus.27213","article-title":"Epidemiological trends of Bell's palsy treated with steroids in Korea between 2008 and 2018","volume":"63","author":"Lee","year":"2021","journal-title":"Muscle Nerve."},{"key":"B2","doi-asserted-by":"publisher","first-page":"1896","DOI":"10.1007\/s00415-019-09282-4","article-title":"The etiology of Bell's palsy: a review","volume":"267","author":"Zhang","year":"2020","journal-title":"J Neurol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"2357","DOI":"10.3390\/jcm10112357","article-title":"Evaluation of effects of diabetes mellitus, hypercholesterolemia and hypertension on Bell's palsy","volume":"10","author":"Psillas","year":"2021","journal-title":"J Clin Med."},{"key":"B4","doi-asserted-by":"publisher","first-page":"27","DOI":"10.7326\/0003-4819-124-1_Part_1-199601010-00005","article-title":"Bell palsy and herpes simplex virus: identification of viral DNA in endoneurial fluid and muscle","volume":"124","author":"Murakami","year":"1996","journal-title":"Ann Intern Med."},{"key":"B5","doi-asserted-by":"publisher","first-page":"157","DOI":"10.1111\/j.1600-065X.1996.tb00915.x","article-title":"Human herpes viruses latent infection in the nervous system","volume":"152","author":"Steiner","year":"1996","journal-title":"Immunol Rev."},{"key":"B6","doi-asserted-by":"publisher","first-page":"323","DOI":"10.1016\/j.autrev.2012.05.008","article-title":"Bell's palsy and autoimmunity","volume":"12","author":"Greco","year":"2012","journal-title":"Autoimmun Rev."},{"key":"B7","doi-asserted-by":"publisher","first-page":"287","DOI":"10.33588\/rn.4105.2004593","volume":"41","author":"De Diego-Sastre","year":"2005","journal-title":"Rev Neurol."},{"key":"B8","doi-asserted-by":"publisher","first-page":"94","DOI":"10.18773\/austprescr.2017.030","article-title":"Management of Bell's palsy","volume":"40","author":"Somasundara","year":"2016","journal-title":"Aust Prescr."},{"key":"B9","doi-asserted-by":"publisher","first-page":"4","DOI":"10.1080\/000164802320401694","article-title":"Bell's palsy: the spontaneous course of 2,500 peripheral facial nerve palsies of different etiologies","volume":"122","author":"Peitersen","year":"2002","journal-title":"Acta Otolaryngol Suppl."},{"key":"B10","doi-asserted-by":"publisher","first-page":"1356","DOI":"10.1136\/jnnp-2014-309563","article-title":"Bell's palsy: aetiology, clinical features and multidisciplinary care","volume":"86","author":"Eviston","year":"2015","journal-title":"J Neurol Neurosurg Psychiatry."},{"key":"B11","doi-asserted-by":"publisher","first-page":"1014","DOI":"10.1097\/00129492-200411000-00026","article-title":"O'dwyer NJ, Adams RD, Croxson GR.
