Post-COVID-19 psychosis: Cotard's syndrome and potentially high risk of harm and self-harm in a first-onset acute and transient psychotic disorder after resolution of COVID-19 pneumonia.

AIM: This report aims to illustrate the possibility of an acute onset of psychosis after COVID-19 infection in a patient without previous history of psychiatric disorders and to highlight the need for early screening and intervention in such cases. METHODS: Clinical presentation of a case, followed by clinical discussion and literature review of the effect of the new coronavirus SARS-CoV-2 and its impact on mental health in terms of neuropsychiatric conditions. RESULTS: We present a case of acute and transient psychotic disorder following complete recovery of COVID-19 bilateral pneumonia. The patient has no prior psychiatric history and presents with acute onset, disorganized behaviour, Cotard's delusion and a potentially high risk of psychotic homicide and suicide. CONCLUSION: Early intervention and treatment with antipsychotic medication are of crucial importance for the effective treatment and complete recovery of these patients.

Brief psychotic disorder with delusion content related to the COVID-19 outbreak.

The COVID-19 outbreak has affected millions of people globally and it also has a huge psychological impact. The objective of this case report is to outline the possible effect of the COVID-19 pandemic to the content of delusions in patients with psychosis. Α 34-year-old male with no history of mental disorder, involuntarily hospitalized due to agitation and aggression towards others, experienced grandiose delusions, referential delusions and delusions of passivity. The content of all his delusions was related to the COVID-19 pandemic. His symptoms were not proven to be caused by any physical condition or substance use disorder. He was prescribed olanzapine 10mg bd and lorazepam 2,5mg td and demonstrated significant improvement with a complete subsidence of his symptoms within a week. He was discharged after a total of 13 days with an ICD-10 diagnosis of brief psychotic disorder. At his 6 months follow-up, he reported no psychiatric symptoms. Existing literature indicates a strong relationship between life experiences and the content of delusions. This case report highlights how the stressful life event of the COVID-19 outbreak affected the content of our patient's delusions.

COVID-19 and psychosis risk: Real or delusional concern?

Historical epidemiological perspectives from past pandemics and recent neurobiological evidence link infections and psychoses, leading to concerns that COVID-19 will present a significant risk for the development of psychosis. But are these concerns justified, or mere sensationalism? In this article we review the historical associations between viral infection and the immune system more broadly in the development of psychosis, before critically evaluating the current evidence pertaining to SARS-CoV-2 and risk of psychosis as an acute or post-infectious manifestation of COVID-19. We review the 42 cases of psychosis reported in infected patients to date, and discuss the potential implications of in utero infection on subsequent neurodevelopment and psychiatric risk. Finally, in the context of the wider neurological and psychiatric manifestations of COVID-19 and our current understanding of the aetiology of psychotic disorders, we evaluate possible neurobiological and psychosocial mechanisms as well as the numerous challenges in ascribing a causal pathogenic role to the infection.

'Constituent Covid-19 apocalypses: contagious conspiracism, 5G, and viral vaccinations'.

The uncertainties and scale of the Covid-19 pandemic has mobilised global anxieties and insecurities, and many cultural groups have conjuncturally embedded conspiracy theories within millennial and apocalyptic thought to explain and find meaning in the pandemic. The apocalypse lends itself well to conspiratorial thinking because conceptually it is flexible enough to reflect any crisis. To this end, the global development of Covid-19 conspiracism is what the authors term 'contagious conspiracism' which is defined as viral global cultural conspiracism. The paper explores how millennialist responses to Covid-19 in various media outlets transcend academic categories of analysis and cultural boundaries between, say, religious and secular, far-right and radical left. First explored is how the crisis became embedded in established (mainly American) contemporary millennial beliefs and prophecies through selected far-right, evangelical and radical left narratives. Second, it is shown how these theories have been 'improvised' to include 5 G and also travelled to Europe and taken on geographical significance in Belfast and Berlin. Third, the authors illustrate the shared ingredients, motivations, and semiotics across apocalyptic conspiratorial Covid-19 narratives, all of which resonate with concerns about power, specifically emergent surveillance technologies, governmental abuse of power, and neoliberal capital, with divergent truths about who is blame from 5 G/vaccine theories to corporate technocapitalism. The paper concludes that these shared discourses across apocalyptic and conspiratorial Covid-19 narratives mean many of us are conspiracists and/or conspiracy theorists at some level and is therefore both revealing of the similarities and has the potential to create democratic constituencies.
