Psychiatry"],"abstract":"<jats:p>Neuropsychiatric symptoms are a common complication of COVID-19, with symptoms documented both during acute COVID-19 infection (parainfectious) and persisting or developing after the resolution of respiratory symptoms (postinfectious). Patients have presented with a variety of symptoms such as anosmia, thrombotic events, seizures, cognitive and attention deficits, new-onset anxiety, depression, psychosis, and rarely catatonia. Etiology appears to be related to disruption of regular neurotransmission and hypoxic injury secondary to systemic inflammation and cytokine storm. Although rare, catatonia and each of its subtypes have now been reported as complications of COVID-19 and therefore should be considered known to occur in both the parainfectious and postinfectious states. Diagnosis of catatonia in the context of COVID-19 should be considered when work-up for more common medical causes of encephalopathy are negative, there is no identifiable psychiatric etiology for catatonia, and there is a positive response to benzodiazepines.<\/jats:p>","DOI":"10.3389\/fpsyt.2021.696347","type":"journal-article","created":{"date-parts":[[2021,7,26]],"date-time":"2021-07-26T05:25:58Z","timestamp":1627277158000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["Postinfectious COVID-19 Catatonia: A Report of Two Cases"],"prefix":"10.3389","volume":"12","author":[{"given":"Tyler","family":"Torrico","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy","family":"Kiong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"D'Assumpcao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uyi","family":"Aisueni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fouad","family":"Jaber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katayoun","family":"Sabetian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Molla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rasha","family":"Kuran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arash","family":"Heidari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,7,26]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"682","DOI":"10.1001\/jamapsychiatry.2021.0500","article-title":"How COVID-19 affects the brain","volume":"78","author":"Boldrini","year":"2021","journal-title":"JAMA Psychiatry."},{"key":"B2","doi-asserted-by":"publisher","first-page":"2810","DOI":"10.1007\/s00415-020-09975-1","article-title":"COVID-19 encephalopathy: detection of antibodies against SARS-CoV-2 in CSF","volume":"267","author":"Andriuta","year":"2020","journal-title":"J Neurol."},{"key":"B3","doi-asserted-by":"publisher","first-page":"577400","DOI":"10.1016\/j.jneuroim.2020.577400","article-title":"COVID-19-related encephalopathy presenting with aphasia resolving following tocilizumab treatment","volume":"349","author":"Muccioli","year":"2020","journal-title":"J Neuroimmunol."},{"key":"B4","doi-asserted-by":"publisher","first-page":"383","DOI":"10.1016\/S1474-4422(20)30109-5","article-title":"Guillain-Barr\u00e9 syndrome associated with SARS-CoV-2 infection: causality or coincidence?","volume":"19","author":"Zhao","year":"2020","journal-title":"Lancet Neurol."},{"key":"B5","doi-asserted-by":"publisher","first-page":"2268","DOI":"10.1056\/NEJMc2008597","article-title":"Neurologic features in severe SARS-CoV-2 infection","volume":"382","author":"Helms","year":"2020","journal-title":"N Engl J Med."},{"key":"B6","doi-asserted-by":"publisher","first-page":"75","DOI":"10.1016\/j.pediatrneurol.2020.10.002","article-title":"NMDA-receptor encephalitis associated with COVID-19 infection in a toddler","volume":"114","author":"Burr","year":"2020","journal-title":"Pediatr Neurol"},{"key":"B7","doi-asserted-by":"publisher","first-page":"18","DOI":"10.1016\/j.seizure.2020.07.006","article-title":"Anti-NMDA receptor encephalitis presenting as new onset refractory status epilepticus in COVID-19","volume":"81","author":"Monti","year":"2020","journal-title":"Seizure."},{"key":"B8","doi-asserted-by":"publisher","first-page":"179","DOI":"10.1016\/j.bbi.2020.05.054","article-title":"Anti-NMDA receptor encephalitis in a psychiatric Covid-19 patient: a case report","volume":"87","author":"Panariello","year":"2020","journal-title":"Brain Behav Immunity."},{"key":"B9","doi-asserted-by":"publisher","first-page":"556","DOI":"10.1016\/j.psym.2020.05.021","article-title":"A case of catatonia in a man with COVID-19","volume":"61","author":"Caan","year":"2020","journal-title":"Psychosomatics."},{"key":"B10","doi-asserted-by":"publisher","first-page":"256","DOI":"10.1016\/j.psym.2020.09.007","article-title":"Life-threatening catatonia associated with coronavirus disease 2019","volume":"62","author":"Deocleciano de Araujo","year":"2021","journal-title":"J Acad Consult Liaison Psychiatry"},{"key":"B11","doi-asserted-by":"publisher","first-page":"e13891","DOI":"10.7759\/cureus.13891","article-title":"Excited catatonia -
