Delusional Content Research Articles

A description of COVID-19 related delusional content in admissions to an acute psychiatric unit.

The COVID-19 pandemic had a profound global impact, affecting individuals, including those with mental illness, through early and widespread information dissemination. Although the neurobiological basis of delusions remains unclear, external stimuli and historical events are known to influence them. The pandemic provided a unique opportunity to explore this phenomenon. To determine the prevalence of COVID-19-related delusional content, among individuals presenting for treatment of psychosis during the peak of the COVID-19 pandemic and investigate associated clinical and demographic factors. Chris Hani Baragwanath Academic Hospital in-patient psychiatry department. Data were extracted retrospectively from adult psychiatric admissions spanning April to September 2020 on patients whose presenting complaints included delusions. Demographic factors, symptoms, psychiatric, medical and substance use history, and a documented Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) diagnosis by the attending psychiatrist were collected. The prevalence of COVID-19-related delusional content was 25.5%. Significant demographic association was observed with education level of Grade 12 and above (p = 0.000338). The odds of a diagnosis of schizophrenia and related disorders were 2.72 times greater than mood and psychotic disorder due to another medical condition in those with COVID- 19-related delusional content (OR 2.19, 95% CI: [1.4-3.4]). The presence of COVID-19-related delusional content in patients admitted to hospital with psychosis provides further evidence of the role of external stimuli in the formation of delusions. This study underscores the influence of socio-cultural factors on delusions and advocates for interventions and expanded research to address mental health outcomes.

The Development of Non-affective Psychotic Syndromes in the 19th Century: LeGrand du Saulle and His 1871 Monograph "Le Délire De Persécutions" (Persecutory Delusions).

While the origins of two of Kraepelin's three subtypes of dementia praecox (DP), catatonic and hebephrenic, are well understood, no similar clear narrative exists for his concepts of paranoia and paranoid DP, which require a consideration of both German and French sources. An important milestone in the French literature is the massive 524 page monograph entitled "Le Délire Des Persécutions" published in 1871 by Henri Legrand du Saulle which contained extensive, clinically detailed descriptions of a wide range of cases with prominent, organized persecutory delusions. Many of his cases reported auditory hallucinations (AH), and some bizarre, Schneiderian delusions. The delusional content could evolve to include prominent somatic and/or grandiose themes. Using a symptomatic diagnostic framework, Legrand du Saulle proposed that this syndrome represented an independent "species" of mental illness. He sought to give a voice to the affected individuals, including a chapter devoted entirely to their writings. He described several clinically fascinating features of such patients including how often they moved residence to unsuccessfully flee their persecutors and how delusional beliefs could be communicated to spouses and relatives. Unlike Kraepelin, he was little interested in their course of illness or rates of deterioration, except to note that recoveries occurred in 20% of cases. The clinical richness of this work substantially exceeded that in the contemporaneous German literature. Most of the cases described by du Saulle would fit easily into the two major non-affective delusional syndromes articulated 28 years later in Kraepelin's famous 6th edition of his textbook: paranoia and paranoid DP.

Does the COVID-19 pandemic condition the delusional content of patients with psychosis? An observational study

IntroductionThe primary objective is to analyse the impact of the COVID-19 pandemic on the triggers of psychopathology and on the delusional content of patients with psychotic symptoms treated during the first three months of the pandemic in a tertiary hospital in Madrid. MethodsWe conducted a cross-sectional, observational and retrospective study of all patients attending the psychiatric emergency room (ER) between 11th March and 11th June 2020. Sociodemographic and clinical variables were included. The chi-squared test or Fisher's exact test were performed to compare categorical variables. The level of statistical significance was set at P < .05. ResultsIn the first month of the pandemic, COVID-19 conditioned the delirious content of 38.5% of the admitted patients and acted as a direct trigger for 46.2% of consultations. In the second week it affected 100.0% of the patients in both cases. Subsequently, a progressive and significant decrease was observed, with COVID-19 being the triggering factor for 17.6% and 11.5% of consultations in the second and third months of the pandemic respectively. Similarly, it was the main determinant of the delusional content in 13.7% and 3.8% of cases respectively. ConclusionsThe current pandemic affects delirium’s pathoplasty. The delusional content of patients admitted with psychotic symptoms is quickly conditioned, which may be related to the radical change in their life, without transition or prior preparation. The patient’s environmental context and events have a huge impact on the dynamics and characteristics of mental disorders.

Differential Trajectories of Delusional Content and Severity Over 2 Years of Early Intervention for Psychosis: Comparison Between Chennai, India, and Montréal, Canada.

There exist few direct studies of delusional content in psychosis across geo-cultural contexts, especially those in which treatment protocols and measures are comparable. To directly examine an illness outcome that is potentially culturally mediated, this study investigated the baseline presentation and longitudinal trajectory of delusions in first-episode psychosis (FEP) across 2 similar treatment settings in Montréal (Canada) and Chennai (India). Patients entering an early intervention program for FEP in Chennai (N = 168) and Montréal (N = 165) were compared on site-level differences in the presentation of delusions across specific time points over 2 years of treatment. Delusions were measured using the Scale for Assessment of Positive Symptoms. Chi-square and regression analyses were conducted. At baseline, delusions were more frequent in Montréal than in Chennai (93% vs 80%, respectively; X2(1) = 12.36, P < .001). Thematically, delusions of grandiosity, religiosity, and mind reading were more common in Montréal than in Chennai (all P < .001); however, these baseline differences did not persist over time. Regression revealed a significant time-by-site interaction in the longitudinal course of delusions, which differs from the trajectory of other FEP-positive symptom domains. To the best of our knowledge, this is the first direct comparison of delusions in similar programs for FEP across 2 different geo-cultural contexts. Our findings support the notion that delusion themes follow consistent ordinal patterns across continents. Future work is needed to unpack the differences in severity that present at baseline and minor differences in content.

Migration, perceived discrimination and the development of psychosis

IntroductionMigration is a rapidly growing phenomenon in European countries and its association with psychotic disorders is a public health concern. Psychosis is more prevalent among migrants, which suggests that adverse social experiences play an important role in its pathogenesis. Throughout the migration process, migrants are exposed to several social disadvantages, including in the post-immigration context, where perceived discrimination appears to be an important stressor. In fact, the highest incidence rates of psychosis occur in the most discriminated populations, namely migrants with darker skin complexion, particularly when living in low-ethnic-density neighborhoods, where both discrimination and social isolation are more prominent.ObjectivesTo conduct an updated review about the association between migration, perceived discrimination and psychosis, aiming to better understand the mechanisms involved.MethodsNarrative literature review using the keywords “migration”; “psychosis”; “discrimination”; “racism” on PubMed database, in conjunction with presentation of a clinical case concerning a patient from Guinea-Bissau, admitted to our hospital in the context of first-episode psychosis (FEP), with onset months after completing the Mediterranean migration route to Europe.ResultsLiterature suggests that experiences of racism and social exclusion contribute to feelings of imminent danger, fear and general anxiety, which may develop into paranoid ideas of ubiquitous persecution. Furthermore, intense social defeat experiences, common in migrants, are associated with more distressing forms of delusional content, with delusions of psychological persecution being more common. However, there is also evidence that migrants with FEP have better occupational and social functioning profiles compared to natives, suggesting that, in these patients, there is a higher burden of social-environmental risk factors, with the onset of psychosis occurring only when this burden overcomes a higher threshold. Our patient fits this description. After completing his migratory route and while living in an Italian refugee camp, he described suffering experiences of severe discrimination. Real or not, these experiences escalated to become delusional ideas of persecution involving European governments, thought to seek for his humiliation. Despite the presence of psychotic symptoms, this patient was able to maintain a reasonable level of functioning during years, up to his psychiatric admission.ConclusionsGiven the notorious effect of perceived discrimination and racism on the increased risk of psychosis in immigrants, it is urgent to adopt policies that promote the social protection of these vulnerable groups, namely through enhancing their integration in the host countries.Disclosure of InterestNone Declared

Delusional Content in Patients with Schizophrenia- A Case Series

Schizophrenia is a chronic and severe mental disorder that affects more than 21 million people worldwide. It is characterised by distortions in thinking, perception, emotions, language, sense of self, and behaviour. Common experiences include hallucinations, mostly involving hearing voices or seeing things that are not there, and delusions, which involve having fixed, false beliefs. This case series presents three patients with schizophrenia who came to the Department of Psychiatry with peculiar delusions. One patient, a 65-year-old, complained of an inability to walk due to the fear of being electrocuted. The second patient, a 25-year-old female, reported the ability to communicate with people in America without the use of any technology. The third patient, aged 20 years, presented with nihilistic delusions. These patients were managed with psychotropics, along with symptomatic treatment for their physical problems. They improved with the interventions and rehabilitation provided to them.

Do Sex/Gender and Menopause Influence the Psychopathology and Comorbidity Observed in Delusional Disorders?

Background: While sex differences and gonadal hormone levels are taken seriously in the understanding and treatment of schizophrenia, their influence in the psychopathology of delusional disorders (DD) remains unknown. Methods: Our strategy was to conduct a narrative review of the effects of (a) sex/gender difference and (b) menopause on delusional content, affective and anxiety-related comorbidity, substance use disorders, cognition, aggressivity, and suicide risk in DD. Results: Because the literature is scarce, our results are tentative. We found that erotomania was more prevalent in women than in men, and especially in women with premenopausal onset. In contrast, jealous and somatic delusions were more commonly seen in DD women with postmenopausal onset. With respect to depressive comorbidity, women with premenopausal onset appear more vulnerable to depression than those with later onset. Age at menopause is reported to correlate positively with intensity of suicidal ideation. Anxiety symptoms may be related to estrogen levels. Men present with higher rates of substance use disorders, particularly alcohol use. Conclusions: Many male/female differences in DD may be attributable to sociocultural factors but menopause, and, therefore, levels of female hormones, influence symptom expression in women and mediate the expression of psychiatric comorbidities. Further research in this area promises to lead to improved individualized treatment.

'An experience of meaning': A 20-year prospective analysis of delusional realities in schizophrenia and affective psychoses.

Delusions are transdiagnostic and heterogeneous phenomena with varying degrees of intensity, stability, and dimensional attributes where the boundaries between everyday beliefs and delusional beliefs can be experienced as clearly demarcated, fuzzy, or indistinguishable. This highlights the difficulty in defining delusional realities. All individuals in the current study were evaluated at index and at least one of six subsequential follow-ups over 20 years in the Chicago Longitudinal Study. We assessed 16 distinct delusions categorized as thought or thematic delusions. We also examined the probability of recurrence and the relationships between delusions and hallucinations, depression, anxiety, and negative symptoms. The sample consisted of 262 individuals with schizophrenia vs. affective psychosis. Thought delusions were significantly different between groups at all follow-up evaluations except the 20-year timepoint. Thematic delusions were more common than thought delusions and show a significant decreasing pattern. In general, delusional content varied over time. Referential, persecutory, and thought dissemination delusions show the highest probability of recurrence. Hallucinations were the strongest indicator for thought, thematic, and overall delusions. The formation and maintenance of delusions were conceptualized as a multimodal construct consisting of sensory, perceptual, emotional, social, and somatic embodiment of an “experience of meanings”. Given the significant associations between delusions and hallucinations, future work incorporating participatory research is needed to better define and align subjective and objective perspectives. Our research also points to the need for future clinical interventions that specifically evaluate and target the coexistence and entanglement of delusions and hallucinations.

Evolution of Delusional Disorder across the DSM editions

IntroductionStates compatible with “Delusional disorder” have been described since the XIX century. Esquirol mentioned “irrational ideas and actions that would develop via logical and plausible arguments”; Kraepelin referred to the condition as “paranoia” and considered that hallucinations could not be present– unlike Bleuler, who considered them to be a possible feature. The criteria for delusional disorder have suffered several changes in the last centuries.ObjectivesWe aim to review the evolution of the criteria for delusional disorder across the editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM).MethodsReview of DSM editions.ResultsCriteria for the diagnosis of “paranoia” (DSM III) or “delusional disorder” (DSM III-IV.V) underwent several changes. In the first editions hallucinations could not be prominent (DSM-III-IIIR) and in the DSM IV, only tactile or olfactory hallucinations related to delusions could be present. In DSM-V hallucinations of other modalities related to the delusional theme can be present. Regarding delusional themes, the first edition of the DSM III regarded persecutory delusions only – which was changed in the DSM-III-R, with the inclusion of grandiose, jealous, erotomaniac, and somatic. Only in the DSM-V did the occurrence of bizarre delusions become possible in delusional disorder. Across the editions, there is a consensus about the absence of negative symptoms, absence of disorganized speech, and that the behavior is not odd aside from delusional content.ConclusionsThe most debatable symptoms across centuries in the classification of delusional disorders were: presence of hallucinations, the nature of the delusional content, and inclusion of bizarre delusions.DisclosureNo significant relationships.

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

IntroductionA 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.ObjectivesEstablish the covid-19 pandemic circumstances as precipitating factors of psychosis independently from other stressorsMethodsThis 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).ResultsWe 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.ConclusionsLiving in a prolonged state of alarm is, in itself, a marked stressor, theoretically capable of increasing the psychosis rate and altering its characteristics.DisclosureNo significant relationships.

Ekbom’s syndrome in an HIV man: a case report

Introduction Ekbom’s syndrome, also known as delusional parasitosis, is a neuropsychiatric disorder characterized by the delusional belief that the body is infested by parasites, small organisms or materials. Multiple etiologies have been described such as psychiatric and neurological disorders, substance intoxication or other medical conditions. We present a case of Ekbom’s syndrome in an individual infected with the human immunodeficiency virus (HIV).ObjectivesTo report a case of a patient with Ekbom’s syndrome and HIV.MethodsA 33-years-old man assists to the emergency unit in order to excessive drowsiness. During the evaluation an antihistamin overdose is confirmed. The patient justifies taking it by claiming to have parasites all over the skin, a fact that is ruled out. Medical history is reviewed presenting multiple visits to GP for thinking that he has parasites, performing medical examinations without alterations. Toxicological, hemogram, biochemistry, hormonal and vitamin study did not show alterations.ResultsDue to the symptoms presented, it was decided to start antipsychotic therapy. At the beginning, the patient is not aware of needing treatment other than antiparasitic. After optimizing the olanzapine dose to reach 20 mg / day, the patient denied experiencing tactile and visual hallucinations.ConclusionsEkbom’s syndrome is a multifactorial neuropsychiatric disorder, individuals infected with HIV are at increased risk of psychotic disorders. The patient was diagnosed of psychotic disorder due to another medical condition because the history of HIV preceded the history of delusional content.DisclosureNo significant relationships.

Prevalence, clinical features, and risk factors of delusions in patients with delirium.

Delirium may be divided into multiple subtypes with different pathological factors. This study aimed to focus on the delirium subtype in which delusions are conspicuous and explore its prevalence, clinical characteristics, and risk factors. The subjects were 601 delirium cases referred to the department of psychiatry over 5years at a general hospital. The Delirium Rating Scale-Revised-98 was used to assess the delusions in patients with delirium, and the features of delusions (delusional form, object, and content) were examined. Multiple regression analysis was applied to determine whether individual factors were associated with the delusions. A total of 78 patients with delirium experienced delusions (13.0%). Most were classified as delusion of reference, such as persecution or poisoning, and 84.3% of patients believed that the persecutors were medical staff members. Older age (p<0.001), female gender (p<0.001), and living alone (p<0.001) were significantly associated with delusions in patients with delirium. The content of delusions was rooted in the distress caused by the patients' medical situation, and the features and risk factors of the delusions suggested a formal similarity with late paraphrenia and "lack-of-contact paranoia." Psychological interventions that consider the isolation, anxiety, and fear behind delusions may be necessary in the care and treatment of these patients.

First-episode psychotic disorders in the wake of the COVID-19 pandemic: a descriptive review of casereports.

Since the onset of COVID-19 pandemic, many case reports and case series dealt with new-onset psychotic disorders in patients either infected with SARS-CoV-2 or thematically linked to the pandemic, but without an infection. Our aim was to provide a comprehensive collection of these reports to illustrate the nature of these psychoses. We conducted a literature search in MEDLINE, Embase, PsycINFO, using search terms regarding first-episode psychotic disorders in the context of corona. 96 case reports or case series covering 146 patients (62 without and 84 with SARS-CoV-2 infection) were found. Compared to patients without infection, patients with infection showed significantly more often visual hallucinations (28.6% vs 8.1%), confusion (36.9% vs 11.3%), an acute onset of illness (88.5% vs 59.6%) and less often depression (13.1% vs 35.5%) and a delusional content related to the pandemic (29.5% vs 78.3%). Both groups had an equally favourable outcome with a duration of psychosis ≤2 weeks in half and full remission in two-thirds of patients. In patients with infection, signs of inflammation were reported in 78.3% and increased CRP in 58.6%. While reports on patients with infection are continuously published, no report about patients without infection was found after July 2020. Cases without infection were considered reactive and originated all from the first wave of the corona pandemic. In cases with infection, inflammation was considered as the main pathogenetic factor but was not found in all patients. Diagnosis was impeded by the overlap of psychosis with delirium.

Delusions with content related to COVID-19 pandemic, in non-infected psychiatric hospitalized patients: a six-case series.

We briefly present a case series of six patients hospitalized in the Department of Psychiatry, University General Hospital of Ioannina, between the first (starting March 23, 2020) and the second (starting November 7, 2020) lockdown in Greece who presented with COVID-19 - related delusional ideas. All patients had negative PCR prior to admission and no history of COVID-19 infection.The first three of our cases were admitted during the first lockdown, between March 23 and May 4, one involuntary and the other two voluntary. The first one was diagnosed with acute and transient psychosis (F23 - First Episode Psychosis) and the other two with psychotic depression (F32.3). Three additional patients were admitted voluntary after the end of the first lockdown. One was diagnosed with acute and transient psychosis (F23-First Episode Psychosis) and the other two were relapses of a known psychiatric disorder (Bipolar disorder F31.5 and Psychotic depression F32.3). At follow-up six months after discharge all patients were in remission following antipsychotic medication, among other medicines. These cases reveal that COVID-19 pandemic may have an impact on the delusional content of new or preexisting psychotic disorders during the COVID-19 pandemic.

The Socio-Cultural and Confessional Dimension of Delusional Ideas Content in the Spectrum of Non-Organic Psychotic Disorders

In the last decade, population clinical trials support the disabling nature of most globally diagnosed psychotic disorders. As a defining integral part of this pathology, the delusional idea considered to be the result of the inaccurate and abnormal interpretation of an external reality is individualized, despite the contrary evidence. This ideation’s clinical expression variability is influenced by a heterogeneous spectrum of biological and psychosocial factors, predisposing and/or favouring. This review’s main objective is to identify a series of relational patterns of the content of delusional ideation with socio-familial and cultural/confessional parameters to obtain a holistic approach to patients. Careful decipherment of these conditions can be the basis for developing new interventions that are much more effective in establishing a long-term diagnostic and therapeutic strategy.

Delusions of Possession and Religious Coping in Schizophrenia: A Qualitative Study of Four Cases.

The notion of evil spirits influencing human behavior or mental processes is used in many cultures to justify various symptoms or experiences. It is also expressed in psychotic delusions of possession, but there is limited research in this area. This study explores how patients with schizophrenia came to the conclusion that they were possessed, and how this affected help-seeking. Interviews with two men and two women about their experiences and meaning-making were subjected to interpretative phenomenological analysis. Three main themes were identified: (1) Links between traumatic experiences and psychotic symptoms, (2) The emergence of religious themes in delusional contents, and (3) Reluctance to use medical treatment and instead to seek exorcism. In each case, attributing problems to possession was supported by the local environment and media, led to seeking spiritual help, and delayed diagnostic assessment and treatment. However, using religious coping contributed to the sense of predictability and social support. Clinicians are encouraged to explore the experiences and conflicts expressed by the symptoms which people ascribe to possession and to negotiate alternative explanatory models with their patients.

Delusional beliefs and their characteristics: A comparative study between dissociative identity disorder and schizophrenia spectrum disorders

Firmly held beliefs that have a delusional quality are commonly experienced in those with schizophrenia spectrum disorders (SSD) and have been reported in those with dissociative identity disorder (DID). However, no study to date has compared delusional belief content and characteristics between these diagnostic groups. This study examined delusional content, and the degree of conviction, preoccupation and distress associated with them in 50 participants with DID and 50 with an SSD exploring also dissociation and childhood trauma as predictors of delusional beliefs. Multivariate analysis of variance and linear regressions were conducted to explore differences between beliefs and characteristics and to examine their association with dissociation and childhood trauma. The SSD sample presented more self-referential delusional beliefs and characteristics compared to the DID group. Yet, the DID group had more mistrust delusional beliefs and characteristics in comparison to SSD participants. Mistrust beliefs were predicted by depersonalization/derealization in the DID sample, but did not predict any delusional belief in the SSD sample. The content of fixed beliefs differs between DID and SSD samples and in this study depersonalization/derealization experiences were related to mistrust beliefs but not to other delusional forms, and only in the DID sample.

Delusional content at initial presentation to a catchment-based early intervention service for psychosis.

During a psychotic episode, patients frequently suffer from severe maladaptive beliefs known as delusions. Despite the abundant literature investigating the simple presence or absence of these beliefs, there exists little detailed knowledge regarding their actual content and severity at the onset of illness. This study reports on delusions during the initiation of indicated treatment for first-episode psychosis (FEP). Data were systematically collected from a sample of 636 patients entering a catchment-based early intervention service for FEP. The average severity and frequency of each delusional theme at baseline was reported with the Scale for the Assessment of Positive Symptoms. Delusional severity (globally and per theme) was examined across a number of sociodemographic and clinical variables. Delusions were present in the vast majority of individuals experiencing onset of FEP (94%), with persecutory (77.7%) being the most common theme. Persecutory delusions remained consistent in severity across diagnoses, but were more severe with older age at onset of FEP. No meaningful differences in delusional severity were observed across gender, affective versus non-affective psychosis, or presence/absence of substance use disorder. Globally, delusion severity was associated with anxiety, but not depression. Delusions commonly referred to as passivity experiences were related to hallucinatory experiences. This community sample offers a rare clinical lens into the severity and content of delusions in FEP. Although delusional severity was consistent across certain sociodemographic and clinical variables, this was not always the case. Future research should now consider the course of delusion themes over time.
