Mental disorders in the course of coronavirus infection are non-specific. They most often have a sudden onset and short-term course and resolve spontaneously or after the administration of low doses of antipsychotic drugs. At the same time, attempts have been made to develop recommendations for COVID-19 therapy. Single reports suggest the effectiveness of amantadine in the treatment. The mechanism of action of the drug in this case is not known; it is expected that amantadine, by reducing the expression of the cathepsin L gene, may interfere with SARS-CoV-2 replication. In addition, this drug stimulates dopaminergic transmission, which may result in numerous side effects, often of a neuropsychological nature, the most common of which are visual hallucinations. Therefore, it is extremely difficult to unequivocally diagnose the cause of mental disorders among patients with SARS-CoV-2 infection who took amatatide for off-label treatment. A clear assessment of whether the psychological symptoms in this group of patients are the primary or secondary clinical manifestation of the infection or a complication of amantadine treatment is difficult. In this context, we attempted to describe a case of a patient with psychotic symptoms who was confirmed with SARS-CoV-2 infection and treated with amantadine.<\/jats:p>","DOI":"10.3390\/ijerph192315768","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T03:28:49Z","timestamp":1669606129000},"page":"15768","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Psychotic Disorders in the Course of SARS-CoV-2 Infection or Uncomplicated Amantadine Treatment?\u2014Case Report"],"prefix":"10.3390","volume":"19","author":[{"given":"Dominika","family":"Tatar","sequence":"first","affiliation":[{"name":"Clinical Department of Psychiatry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 40-055 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krzysztof","family":"\u015awierzy","sequence":"additional","affiliation":[{"name":"Clinical Department of Psychiatry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 40-055 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4438-2376","authenticated-orcid":false,"given":"Micha\u0142","family":"B\u0142achut","sequence":"additional","affiliation":[{"name":"Clinical Department of Psychiatry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 40-055 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1810-9018","authenticated-orcid":false,"given":"Karina","family":"Badura Brzoza","sequence":"additional","affiliation":[{"name":"Clinical Department of Psychiatry, Faculty of Medical Sciences in Zabrze, Medical University of Silesia in Katowice, 40-055 Katowice, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"113097","DOI":"10.1016\/j.psychres.2020.113097","article-title":"New-onset psychosis in COVID-19 pandemic: A case series in Madrid","volume":"290","author":"Rentero","year":"2020","journal-title":"Psychiatry Res."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1016\/j.bbi.2020.03.031","article-title":"Nervous system involvement after infection with COVID-19 and other coronaviruses","volume":"87","author":"Wu","year":"2020","journal-title":"Brain Behav.
