A case of Kretschmer's sensitive delusion related to COVID-19 pandemic

Presents a case report of a 45-year-old woman with a brief psychotic disorder, in which pathogeny was an effect of the pandemic, modulating a classic syndrome described more than one century ago by Ernst Kretschmer. During the mandatory screening before hospital admission, the patient tested positive for SARS-CoV-2. Basic tests were performed, including blood alcohol concentration, urinary drug screening, and brain computerized tomography - all normal. Regarding her premorbid personality, she had cluster C personality traits. The discharge diagnosis was a Brief psychotic disorder. Other differential diagnoses were considered such as schizophreniform disorder, psychotic depression, bipolar disorder, late-onset schizophrenia, but the rapid onset of the picture, the brief resolution, the absence of dominant affective symptomatology, and the absence of negative symptomatology led to assume that it was more likely a brief reactive psychosis. antipsychotic medication was suspended gradually and she didn't present any recurrence of symptoms. In this case report, the author reviews a classic nosological entity, commonly forgotten, revived by a very current and particular social situation (the COVID-19 pandemic), whose social conditionings can affect mental health. The author emphasizes the importance of a thorough anamnesis with a complete evaluation of the premorbid character, which allowed an early intervention and subsequent better prognosis.

Delusions and Fixed Beliefs in the Age of the Internet: When Do Conspiracy Theories Become Illness?

The internet, especially in the form of social media, provides an avenue for dissemination of unusual and fixed ideas. Recently, the role of conspiracy theories (CTs) in perpetuating myths about the Coronavirus disease (COVID-19) has attracted the attention of mental health practitioners. While extreme CTs may carry some similarities to delusions and may occur in similar socioeconomic groups, some distinctions can be made in the clinical setting. There is little evidence that social media use or gaming with virtual-reality tools on the internet cause psychotic illness, although the internet does promote CTs. Nevertheless, individuals with psychotic illness are overrepresented among internet users and this may allow for greater exposure to unusual beliefs. Future immersive experiences on the internet such as virtual reality and the metaverse may present challenges for people at risk of developing fixed beliefs, but research will be needed on this subject.

A Clinical Psychological View about Delusional Characterizations in Subjects with Schizophrenia Spectrum Disorder during the COVID-19 Period.

(Background) The period experienced during the COVID-19 virus and the respective social regulations associated with it caused enormous psychosocial stress. (Objective) The objective of the present work was to observe whether the lived period induced a change in delusional characterizations in subjects with schizophrenia spectrum disorder. (Methods) A systematic literature review was conducted following the PRISMA 2020 guidelines for systematic reviews of the PRISMA GROUP. The literature search was conducted from November 2021 to May 2022, using various scientific platforms including PubMed. (Results) A total of 865 articles were found, from which 176 duplicates were removed. The remaining articles were reviewed by reading the titles and abstracts; fourteen were included. (Conclusions) During this research, it was possible to confirm the initial thesis, namely that delirium absorbs external reality by being modified by it. It was observed that the speed of absorption is estimated to be directly proportional to the speed of the modification of social reality and to the impact that the latter has on the subject's private sphere. Moreover, the situation of radical change represented a condition of abnormal psychosocial stress, which led to an increase in diagnoses of schizophrenia spectrum disorders and, specifically, a weighty increase in diagnoses of brief psychotic disorder (BDP). In the coming years, it is estimated that there will be an increase in diagnoses of schizophrenia spectrum disorder caused by both environmental and biological factors.

Experience of psychosis during the COVID-19 pandemic among hospitalized patients

The content of auditory hallucinations (AHs) and delusions is malleable and reflects the social environment and the local culture. COVID-19 is a significant new feature of the social environment, yet research has not yet determined how the phenomenology of psychosis has changed since the COVID-19 outbreak. Adult patients (N = 17) receiving care within an acute inpatient psychiatric care setting in Boston were recruited to participate in an hour-long Zoom interview about their psychosis phenomenology and the potential impact of COVID-19. Thematic analysis of interview data found that for many, ideas about COVID-19 were present in the content of their AHs and shaped their paranoid ideation. Some felt that the frequency and loudness of the AHs had increased. However, not all participants spoke in ways that suggested the virus had affected their experience. Results demonstrate that COVID-19 influenced the content of psychosis for many, but the effect of COVID-19 on psychosis was not uniform. The increased social isolation, financial insecurity, and socio-political climate of the period also seemed to negatively impact individuals with psychosis. Understanding how COVID-19 specifically has influenced psychosis helps to illustrate how societal and external factors may shape this experience.

Clinical-Immunological Correlates in Post-COVID-19 Endogenous Psychoses.

Objectives. To carry out a clinical and immunological study of the potential impact of coronavirus infection on the course of endogenous psychoses. Materials and methods. A total of 33 female patients aged 16-48 years with depressive-delusional states (F20.01, F21, F31) developing after coronavirus infections took part; group 1 consisted of 15 people who developed depressive-delusional states 1-2 months after COVID-19; group 2 consisted of 18 people with similar psychoses developing at later time points (2-6 months). The severity of psychopathological symptoms was assessed using the PANSS and HDRS-21 scales. The activity of inflammatory markers leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) was determined in patients' blood. Absolute neutrophil and lymphocyte contents and their ratio (the neutrophil:lymphocyte index) were also evaluated. Standard values for indicators from healthy donors corresponding to patients in terms of age and sex were used as control values. Results. Endogenous psychosis developing at longer intervals after coronavirus infection (group 2) was found to be associated with "typical" inflammatory reactions, with increases in the activity of acute-phase proteins (α1-PI: 43.0 (35.6-49.7) IU/ml, p = 0.001) and neutrophil degranulation activity (LE - 254.8 (238.0-271.0) nmol/min·ml, p < 0.001), which was associated with the development of depressive-delusional states with dominance of manifestations of positive affectivity (anxiety, melancholy) and the extended nature of delusional disorders, which were mostly incongruent to affect. Conversely, development of endogenous psychosis during the first two months after COVID-19 (group 1) was characterized by a spectrum of inflammatory biomarkers with a decrease in neutrophil count ((2.6 ± 0.9)·109/liter, p < 0.05) and low LE activity (196 (172-209.4) nmol/min·ml, p < 0.001). This immunological profile was associated with predominance of manifestations of negative affectivity (apathy, asthenia, adynamia) in the structure of depressive-delusional states and the relatively undeveloped nature of delusional disorders, which were predominantly congruent to affect. Conclusions. The clinical and biological correlates found here presumptively indicate that experience of COVID-19 infection has a modulatory effect on neuroinflammation and the structure of endogenous psychosis.

Multisite randomised controlled trial of trauma-focused cognitive behaviour therapy for psychosis to reduce post-traumatic stress symptoms in people with co-morbid post-traumatic stress disorder and psychosis, compared to treatment as usual: study protocol for the STAR (Study of Trauma And Recovery) trial.

BACKGROUND: People with psychosis have high rates of trauma, with a post-traumatic stress disorder (PTSD) prevalence rate of approximately 15%, which exacerbates psychotic symptoms such as delusions and hallucinations. Pilot studies have shown that trauma-focused (TF) psychological therapies can be safe and effective in such individuals. This trial, the largest to date, will evaluate the clinical effectiveness of a TF therapy integrated with cognitive behaviour therapy for psychosis (TF-CBTp) on post-traumatic stress symptoms in people with psychosis. The secondary aims are to compare groups on cost-effectiveness; ascertain whether TF-CBTp impacts on a range of other meaningful outcomes; determine whether therapy effects endure; and determine acceptability of the therapy in participants and therapists. METHODS: Rater-blind, parallel arm, pragmatic randomised controlled trial comparing TF-CBTp + treatment as usual (TAU) to TAU only. Adults (N = 300) with distressing post-traumatic stress and psychosis symptoms from five mental health Trusts (60 per site) will be randomised to the two groups. Therapy will be manualised, lasting 9 months (m) with trained therapists. We will assess PTSD symptom severity (primary outcome); percentage who show loss of PTSD diagnosis and clinically significant change; psychosis symptoms; emotional well-being; substance use; suicidal ideation; psychological recovery; social functioning; health-related quality of life; service use, a total of four times: before randomisation; 4 m (mid-therapy); 9 m (end of therapy; primary end point); 24 m (15 m after end of therapy) post-randomisation. Four 3-monthly phone calls will be made between 9 m and 24 m assessment points, to collect service use over the previous 3 months. Therapy acceptability will be assessed through qualitative interviews with participants (N = 35) and therapists (N = 5-10). An internal pilot will ensure integrity of trial recruitment and outcome data, as well as therapy protocol safety and adherence. Data will be analysed following intention-to-treat principles using generalised linear mixed models and reported according to Consolidated Standards of Reporting Trials-Social and Psychological Interventions Statement. DISCUSSION: The proposed intervention has the potential to provide significant patient benefit in terms of reductions in distressing symptoms of post-traumatic stress, psychosis, and emotional problems; enable clinicians to implement trauma-focused therapy confidently in this population; and be cost-effective compared to TAU through reduced service use. TRIAL REGISTRATION: ISRCTN93382525 (03/08/20).

Novel psychopathological picture during the COVID-19 pandemic based on a first episode of psychotic depression. / Nowy obraz objawów psychopatologicznych w dobie pandemii COVID-19 na podstawie pierwszego epizodu depresji psychotycznej.

The emerging SARS-CoV-2 pandemic is known to take a toll on both physical and mental health. We present a case of a patient with a first episode of severe depression with COVID-19-related psychotic features. A patient with no history of mental disorders was admitted to the Psychiatric Unit due to the symptoms of severe depressive episode with psychotic features. Progressive deterioration of his mental health, behavior and activity was observed in March of 2020. He was not infected nor exposed to infectious agents but presented delusions about being infected with SARS-CoV-2 and being a source of transmission to other people. He suffered from Hashimoto disease and recently diagnosed lymphoma which further diagnosis was postponed. He was administrated venlafaxine 150 mg and mirtazapine 45 mg with addition of olanzapine up to 20 mg and risperidone up to 6 mg per day. No side effects were reported. The patient reached a full recovery with the exception of slightly blunted ability to feel pleasure, minor problems with concentration and occasional pessimistic thoughts. Discussion: The social distancing recommendations put a psychological strain related to alienation and negative emotions which can favor development of depressive symptoms. Analysis of psychological mechanisms related to the pandemic and restrictions is significant for limiting negative influence of global crisis on individual mental well-being. Conclusions: In this case the impact of global anxiety and its integration into the developing psychopathological symptoms is especially significant. The circumstances surrounding an episode of affective disorder may shape its course and thought content.

Are conspiracy theorists psychotic? A comparison between conspiracy theories and paranoid delusions

Introduction: Conspiracy theories are popular during the COVID- 19 pandemic. Conspiratorial thinking is characterised by the strong conviction that a certain situation that one sees as unjust is the result of a deliberate conspiracy of a group of people with bad intentions. Conspiratorial thinking appears to have many similarities with paranoid delusions. Objective(s): To explore the nature, consequences, and socialpsychological dimensions of conspiratorial thinking, and describe similarities and differences with paranoid delusions. Method(s): Critically assessing relevant literature about conspiratorial thinking and paranoid delusions. Result(s): Conspiratorial thinking meets epistemic, existential, and social needs. It provides clarity in uncertain times and connection with an in-group of like-minded people. Both conspiratorial thinking and paranoid delusions involve an unjust, persistent, and sometimes bizarre conviction. Unlike conspiracy theorists, people with a paranoid delusion are almost always the only target of the presumed conspiracy, and they usually stand alone in their conviction. Furthermore, conspiracy theories are not based as much on unusual experiences of their inner self, reality, or interpersonal contacts. Conclusion(s): Conspirational thinking is common in uncertain circumstances. It gives grip, certainty, moral superiority and social support. Extreme conspirational thinking seems to fit current psychiatric definitions of paranoid delusions, but there are also important differences. To make a distinction with regard to conspiratorial thinking, deepening of conventional definitions of delusions is required. Instead of the strong focus on the erroneous content of delusions, more attention should be given to the underlying idiosyncratic, changed way of experiencing reality.

Covid -19 pandemic's impact on the clinical presentation of brief psychotic disorders

Introduction: A major increase in mental health issues was noted since the outbreak of the covid-19 pandemic even in patients with no history of mental health illness, specifically brief psychotic disorders. Objective(s): Establish the covid-19 pandemic circumstances as precipitating factors of psychosis independently from other stressors Methods: This is a cross-sectional and descriptive study carried out in the psychiatric department of the University Hospital of Mahdia including two groups of patients over a period of 15 months: From October 2018 to December 2019 are pre-covid cases, and the second group consists of the ones admitted between June 2020 and August 2021. We have collected the data of patients diagnosed with brief psychotic disorder according to DSM-5. We have focused on two clinical characteristics of the psychotic episodes (theme of delusions, stressors). Result(s): We have collected 19 patients, 12 among them during the pre-covid period. In our pre-covid period, brief psychotic disorder presented mostly with marked stressors (33.3%) whilst in the middle of the pandemic, marked stressors are present in only 14.3% of the cases. Which could suggest that this state of alarm can singlehandedly trigger psychosis. For the theme of delusions, in the pre-covid period, the religious theme appeared to be the most frequent (58.3%), whilst during the pandemic, persecution became the most prevalent (71.4%), showing how living in fear of contracting the virus could manifest itself in delusional content. Conclusion(s): Living in a prolonged state of alarm is, in itself, a marked stressor, theoretically capable of increasing the psychosis rate and altering its characteristics.

The COVID-19 Pandemic and Psychosis: The Unusual Insight

Background: COVID, believed to have emerged in Wuhan, China in Nov, 19 and swiftly spread like wildfire across the continents. It wasn't much of a fantasy that it would become a headache for governments all over the world and would have a devastating impact on every sector alike, ravaging economies, especially medicine and healthcare. It was declared as a global pandemic in March, 2020. Predominantly thought of causing only pulmonary complications, it was soon revealed to be causing multiple neuropsychiatric complications in a few cases. Although it was with limited evidence, it was significant enough much like it's counterparts SARS-CoV-1 and MERS. Neurological problems ranged from a spectrum of anxiety to delusions, to even psychosis in some patients. However, the origin and pathogenesis of a COVID induced psychosis is still very much of a question mark. Since, many of the patient's diagnosis could be traced back to their family roots or some kind of substance abuse. In this review, the aim is to assess various associations which could be leading patients to developing new onset psychosis and the possible complications arising out of COVID-19 pandemic. Objective: The purpose of this review article is to analyse the multiple case reports and their data interpretation reported throughout the world during COVID pandemic and give a summarised view. Methodology: Various articles were searched individually containing significant key words that are in relevance to the mental illnesses comprising words like COVID, psychosis, schizophrenia, pandemic, mental illness across various platforms that is PubMed, Google scholar, BMJ, Medline, Frontiers, Sage journals and various news articles and were summed up so as in an attempt to come to a conclusion which could lead to a certain possible ethology and the risk factors involved.

The impact of the first UK COVID-19 lockdown on presentations with psychosis to mental health services for older adults: An electronic health records study in South London.

OBJECTIVES: Social distancing restrictions in the COVID-19 pandemic may have had adverse effects on older adults' mental health. Whereby the impact on mood is well-described, less is known about psychotic symptoms. The aim of this study was to compare characteristics associated with psychotic symptoms during the first UK lockdown and a pre-pandemic comparison period. METHODS: In this retrospective observational study we analysed anonymised records from patients referred to mental health services for older adults in South London in the 16-week period of the UK lockdown starting in March 2020, and in the comparable pre-pandemic period in 2019. We used logistic regression models to compare the associations of different patient characteristics with increased odds of presenting with any psychotic symptom (defined as hallucinations and/or delusion), hallucinations, or delusions, during lockdown and the corresponding pre-pandemic period. RESULTS: 1991 referrals were identified. There were fewer referrals during lockdown but a higher proportion of presentations with any psychotic symptom (48.7% vs. 42.8%, p = 0.018), particularly hallucinations (41.0% vs. 27.8%, p < 0.001). Patients of non-White ethnicity (adjusted odds ratio (OR): 1.83; 95% confidence interval (CI): 1.13-2.99) and patients with dementia (adjusted OR: 3.09; 95% CI: 1.91-4.99) were more likely to be referred with psychotic symptoms during lockdown. While a weaker association between dementia and psychotic symptoms was found in the pre-COVID period (adjusted OR: 1.55; 95% CI: 1.19-2.03), interaction terms indicated higher odds of patients of non-White ethnicity or dementia to present with psychosis during the lockdown period. CONCLUSIONS: During lockdown, referrals to mental health services for adults decreased, but contained a higher proportion with psychotic symptoms. The stronger association with psychotic symptoms in non-White ethnic groups and patients with dementia during lockdown suggests that barriers in accessing care might have increased during the COVID-19 pandemic.

Prevalence and risk factors of self-reported psychotic experiences among high school and college students: A systematic review, meta-analysis, and meta-regression.

BACKGROUND: Adolescents are at high risk of incident psychopathology. Fleeting psychotic experiences (PEs) that emerge in young people in response to stress may be warning signs that are missed by research that fails to study stressed populations, such as late high school and college/university students. Our aim in this systematic review was to conduct a meta-analysis that estimates prevalence rates of PEs in students, and to assess whether these rates differ by gender, age, culture, and COVID-19 exposure. METHOD: We searched nine electronic databases, from their inception until January 31, 2022 for relevant studies. We pooled the estimates using the DerSimonian-Laird technique and random-effects meta-analysis. Our main outcome was the prevalence of self-reported PEs in high school and college/university students. We subsequently analyzed our data by age, gender, population, country, culture, evaluation tool, and COVID-19 exposure. RESULTS: Out of 486 studies retrieved, a total of 59 independent studies met inclusion criteria reporting 210' 024 students from 21 different countries. Nearly one in four students (23.31%; 95% CI 18.41%-29.05%), reported having experienced PEs (heterogeneity [Q = 22,698.23 (62), p = 0.001] τ2  = 1.4418 [1.0415-2.1391], τ = 1.2007 [1.0205-1.4626], I2  = 99.7%, H = 19.13 [18.59-19.69]). The 95% prediction intervals were 04.01%-68.85%. Subgroup analyses showed that the pooled prevalence differed significantly by population, culture, and COVID-19 exposure. CONCLUSION: This meta-analysis revealed high prevalence rates of self-reported PEs among teen and young adult students, which may have significance for mental health screening in school settings. An important realization is that PEs may have very different mental health meaning in different cultures.

The Prevalence of Psychotic Symptoms, Violent Ideation, and Disruptive Behavior in a Population With SARS-CoV-2 Infection: Preliminary Study.

BACKGROUND: The COVID-19 disease results from infection by the SARS-CoV-2 virus to produce a range of mild to severe physical, neurological, and mental health symptoms. The COVID-19 pandemic has indirectly caused significant emotional distress, triggering the emergence of mental health symptoms in individuals who were not previously affected or exacerbating symptoms in those with existing mental health conditions. Emotional distress and certain mental health conditions can lead to violent ideation and disruptive behavior, including aggression, threatening acts, deliberate harm toward other people or animals, and inattention to or noncompliance with education or workplace rules. Of the many mental health conditions that can be associated with violent ideation and disruptive behavior, psychosis can evidence greater vulnerability to unpredictable changes and being at a greater risk for them. Individuals with psychosis can also be more susceptible to contracting COVID-19 disease. OBJECTIVE: This study aimed to investigate whether violent ideation, disruptive behavior, or psychotic symptoms were more prevalent in a population with COVID-19 and did not precede the pandemic. METHODS: In this preliminary study, we analyzed questionnaire responses from a population sample (N=366), received between the end of February 2021 and the start of March 2021 (1 year into the COVID-19 pandemic), regarding COVID-19 illness, violent ideation, disruptive behavior, and psychotic symptoms. Using the Wilcoxon rank sum test followed by multiple comparisons correction, we compared the self-reported frequency of these variables for 3 time windows related to the past 1 month, past 1 month to 1 year, and >1 year ago among the distributions of people who answered whether they tested positive or were diagnosed with COVID-19 by a clinician. We also used multivariable logistic regression with iterative resampling to investigate the relationship between these variables occurring >1 year ago (ie, before the pandemic) and the likelihood of contracting COVID-19. RESULTS: We observed a significantly higher frequency of self-reported violent ideation, disruptive behavior, and psychotic symptoms, for all 3 time windows of people who tested positive or were diagnosed with COVID-19 by a clinician. Using multivariable logistic regression, we observed 72% to 94% model accuracy for an increased incidence of COVID-19 in participants who reported violent ideation, disruptive behavior, or psychotic symptoms >1 year ago. CONCLUSIONS: This preliminary study found that people who reported a test or clinician diagnosis of COVID-19 also reported higher frequencies of violent ideation, disruptive behavior, or psychotic symptoms across multiple time windows, indicating that they were not likely to be the result of COVID-19. In parallel, participants who reported these behaviors >1 year ago (ie, before the pandemic) were more likely to be diagnosed with COVID-19, suggesting that violent ideation, disruptive behavior, in addition to psychotic symptoms, were associated with COVID-19 with an approximately 70% to 90% likelihood.

Religious Fundamentalism, Delusions, and Conspiracy Beliefs Related to the COVID-19 Pandemic.

The widespread COVID-19 conspiracy theories are a problem in dealing with the pandemic, as their proponents tend not to adhere to public health regulations. The aim of this study was to analyse the relationships between religious fundamentalism, delusions, compliance with public health regulations, and religion-related conspiracy beliefs about the COVID-19 pandemic. The participants were 570 internet users aged 18-60. They responded to questions regarding sociodemographic variables, compliance with public health regulations, conspiracy beliefs concerning COVID-19, as well as the Revised Religious Fundamentalism Scale, and the Delusions Scale. The results indicated that people exhibiting more conspiracy beliefs were less likely to comply with public health regulations concerning the COVID-19 pandemic and showed more religious fundamentalism. Additionally, there was an indirect effect of religious fundamentalism on conspiracy beliefs through delusions. The results suggest that when formulating epidemiological messages, it is worth paying attention to the importance of rational thinking.

[Clinical and immunological correlates in endogenous psychoses developed after COVID-19]. / Kliniko-immunologicheskie korrelyaty pri endogennykh psikhozakh, razvivshikhsya posle perenesennogo COVID-19.

OBJECTIVE: The clinical and immunological study of the potential impact of coronavirus infection on the course of endogenous psychosis. MATERIAL AND METHODS: Thirty-three female patients, aged 16 to 48 years, with depressive-delusional conditions (ICD-10 F20.01, F21, F31) developed after coronavirus infection, of whom 15 people (group 1) had depressive-delusional states 1-2 months after COVID-19 and 18 people (group 2), who developed similar psychoses in later periods (2-6 months). The severity of the psychopathologic symptoms was evaluated with PANSS and HDRS-21 scales. The activity of inflammatory markers - leukocyte elastase (LE) and α1-proteinase inhibitor (α1-PI) in the blood was determined. The absolute neutrophil count, the absolute lymphocyte count and the neutrophil/lymphocyte ratio were calculated. As a control, we used standard values of indicators of age - and sex-matched healthy donors. RESULTS: The endogenous psychosis that developed later after a coronavirus infection (group 2) is associated with a "typical" inflammatory reaction with an increase in the activity of acute phase proteins (according to α1-PI) and degranulation activity of neutrophils (according to LE), which is associated with the development of depressive-delusional states in patients with the dominance of manifestations of positive affectivity (anxiety, melancholy) and the extended nature of delusional disorders, which were predominantly incongruent to affect. On the contrary, the development of endogenous psychosis during the first two months after COVID-19 (group 1) is characterized by a spectrum of inflammatory biomarkers with a decrease in the number of neutrophils and low activity of LE. This immunological profile is associated with the predominance of manifestations of negative affectivity (apathy, asthenia, adynamia) in the structure of depressive-delusional states and the relatively undeveloped nature of delusional disorders, which were predominantly congruent to affect. CONCLUSION: The clinical and biological correlates presumably indicate the modulating effect of the coronavirus infection (COVID-19) on neuroinflammation and the structure of endogenous psychosis.

Delirium and Psychiatric Sequelae Associated to SARS-CoV-2 in Asymptomatic Patients With Psychiatric History and Mild Cognitive Impairment as Risk Factors: Three Case Reports.

Human coronaviruses have neuroinvasive and neurotropic abilities that might explain psychiatric outcomes in affected patients. We hypothesized that delirium might be the sole clinical manifestation or even the prodrome of a psychiatric episode consistent with the mental history of a few infected patients with a preexisting diagnosed cognitive impairment. We examined three patients with preexisting mild cognitive impairment and delirium at admission for suspected SARS-CoV-2 infection. We diagnosed delirium using DSM-5 and Confusion Assessment Method (CAM) and measured consciousness level by the Glasgow Coma Scale. All the patients had no history of fever, respiratory complications, anosmia or ageusia, meningitis, and negative cerebrospinal fluid analysis for SARS-CoV-2. Our first patient had no psychiatric history, the second reported only a depressive episode, and the third had a history of bipolar disorder dated back to 40 years before. In the first patient, delirium resolved 2 days following the admission. The other two patients recovered in 4 and 14 days, and delirium appeared as the prodrome of a new psychiatric episode resembling past events. Clinicians should monitor the possibility that SARS-CoV-2 presence in the brain might clinically manifest in the form of delirium and acute psychiatric sequelae, even without other systemic symptoms. Psychiatric history and preexisting mild cognitive impairment are to be considered as predisposing factors for COVID-19 sequelae in delirium patients.

Investigating predictors contributing to the expression of schizotypy during the COVID-19 pandemic.

The coronavirus (COVID-19) pandemic has caused major disruptions to social and other forms of functioning, which may influence schizotypy expression. The current study aimed to explore possible distal and proximal predictors contributing to schizotypy in a sample of the Australian general population during the COVID-19 pandemic. The COvid-19 and you: mentaL heaLth in AusTralia now survEy (COLLATE) project is an online mental health study aimed at tracking key mental health indicators over the progression of the pandemic. Adults residing in Australia were invited to take part using non-discriminative snowball sampling. Demographic-clinical information was collected for 850 participants in either October 2020 or January 2021. To assess schizotypy facets, the Launay-Slade Hallucinations Scale-Extended (LSHS-E) and Peters Delusions Inventory (PDI-21) were used to measure hallucination and delusion proneness respectively. Generalised linear models (with gamma and negative binomial distributions) were employed. Age, negative emotions and loneliness significantly contributed to both hallucination and delusion proneness; gender, education and religiosity also significantly contributed to delusion proneness, in the final regression models. Our study corroborated the specific contribution of loneliness, amongst other factors, in the prediction of schizotypy facets. Tackling loneliness represents a public health challenge that needs to be urgently addressed, especially in the face of the ongoing COVID-19 pandemic.

Using Telemedicine to Assess and Manage Psychosis Among Outpatients with Neurodegenerative Disease.

The presence of hallucinations and delusions in patients with neurodegenerative disease correlates negatively with function, cognition, quality of life, and survival. When these patients still have insight, the treatment of mild hallucinations may reduce the risk of progression to more severe symptoms, specifically hallucinations without insight or delusions. On October 22, 2020, a multidisciplinary consensus panel comprising United States-based experts in geriatric psychiatry, geriatric medicine, family medicine, movement disorders, and neuropsychology was convened remotely to discuss best practices for using telemedicine to evaluate, diagnose, and treat psychosis in patients with neurodegenerative diseases. This review reflects the opinions and recommendations discussed at this meeting. Despite drawbacks, telemedicine can offer several advantages over in-person care, particularly for older adults, and may be a unique opportunity for care of patients with neuropsychiatric symptoms. While telemedicine may not be suitable for all patients, it allows the involvement of specialists from multiple geographic locations and the extension of care to homebound individuals. Patients with neurodegenerative diseases who are likely to become homebound as the disease advances may benefit greatly from telemedicine as a standard of care. Healthcare provided via telemedicine should be nothing less than what would be offered to the patient in person. Telemedicine may present some difficulties, including technological issues and inherent constraints of remote care, but with proper planning many problems could be diminished. Technical issues associated with telemedicine are inevitable but may be partially offset by providing clear directions ahead of any tele-visit to ensure connectivity and access to the videoconferencing platform. Alternative procedures to communicate should be established in the eventuality of technological issues. Using these strategies, telemedicine can serve as a valuable complement to traditional in-person practices for the diagnosis and management of hallucinations and delusions associated with Parkinson's disease psychosis or dementia-related psychosis.

Weaved around COVID-19: Case series of coronavirus thematic delusions.

Stressful situations such as the COVID-19 pandemic can serve as a niche for developing pathological mental state or influence the symptomatology of patients with psychiatric disorders. Here, we present four such cases. Three cases highlight the onset of psychosis precipitated by the immense stress posed by the pandemic. In the last case, psychopathology of a patient with preexisting mental illness getting influenced by the pandemic is highlighted. In all the four cases, it is interesting to note that delusional work is weaved around the COVID-19.

First psychotic episode, related to COVID-19 pandemic, in a patient with tuberous sclerosis complex.

Clinical symptoms of tuberous sclerosis may occur because of exposure to a stressful event like COVID-19. During pandemics, specific considerations should be deserved to the mental state of people suffering from genetic diseases to prevent mental illness caused by a coronavirus.
