Assessing Psychological Explanations for Jesus’ Post-Resurrection Appearances: A Response to Stephen H. Smith

Abstract In a recent article published in this journal, Stephen Smith acknowledges that bereavement hallucination is an unlikely explanation for Jesus’ post-resurrection appearances, and suggests supplementing it with theories concerning collective delusion, distorted memory, and cognitive dissonance. Our response contributes to the discussion by bringing our expertise in psychology and New Testament studies together to advance interdisciplinary study on this important topic. We show that Smith’s discussion confounds real-life cases and laboratory experiments on memory, and mass psychogenic illness with illusions. Moreover, Smith fails to consider a number of important differences between the case concerning Jesus’ post-resurrection appearances and cases of cognitive dissonance and other psychological theories, which indicate that these theories are not plausible explanations concerning Jesus’ post-resurrection appearances.

Contagion of fear: Investigating the psychology and effects of mass hysteria

Abstract: Mass hysteria, or mass psychogenic illness (MPI), refers to the rapid spread of symptoms or behaviors within a group without an identifiable physical cause, often triggered by psychological and social factors. This case report details an outbreak of MPI, commonly known as mass hysteria, at a girls’ boarding school in central Odisha. The incident was triggered by a 12-year-old student, Miss A, who exhibited physical symptoms such as fainting, shaking, and abdominal pain. These symptoms quickly spread to almost 100 other students. Medical evaluations found no physical cause, confirming the psychogenic origin of the outbreak. Cultural beliefs in malevolent spirits and social contagion were key factors in the spread, especially among the young, impressionable students. This case highlights the psychological and social mechanisms behind MPI outbreaks and emphasizes the importance of addressing mental health and cultural beliefs when managing such incidents.

Advantage of neuroeducation in managing mass psychogenic illness among rural school children in Nepal.

Mass psychogenic illness (MPI), also known as mass hysteria (MH), is a mental health disorder that frequently occurs in Nepal. It primarily affects female students in government high schools and occurs during the course of the school day over a few days without corresponding organic causes. This study set out to evaluate and give neuroeducation with the goal of preventing and/or managing MPI after documenting the existing state of knowledge regarding MPI. A total of 234 female students in grades 6 through 10 who attended MH-affected schools (SMH, n=119) and schools without a mass hysteria history (SNOMH, n=114) participated in this mass hysteria awareness study. Participants received written pre- and posttests formatted as questionnaires before and after receiving neuroeducation by watching a drama, viewing a human brain-spinal cord model demonstration, and attending an instructive lecture on the human neurological system, stress, and mass hysteria. Our neuroeducation awareness study on mass hysteria was found to be effective among all of the participants from both SMH and SNOMH. The results indicated that the aforementioned neuroeducation tools are more effective in improving knowledge about mental stress differently in different grades of SMH and SNOMH students. The basic understanding of the human neurological system was not improved by the neuroeducation tool, according to our findings. Our study suggests that using day-structured neuroeducational tools might be an efficient way to treat mass psychogenic illness in Nepal.

A Systematic Review of Research Developments in Mass Psychogenic Illness

This study explores the development of research on mass psychogenic illness (MPI) over recent decades. The literature review was used as the research methodology for this study, and dozens of published case reports and studies are reviewed in this paper. First, the paper reviews past researchers' general recognition of mass psychogenic illness. The paper includes the two subtypes of mass psychogenic disorders, 'mass anxiety hysteria' and 'mass motor hysteria', as well as the characteristics and common symptoms of the outbreak of mass psychogenic illness and the suspicion of the existence of mass psychogenic illness by some scholars. Secondly, historical cases of mass psychogenic illness outbreaks are reviewed in chronological order, from the Middle Ages through to the 21st century. Thirdly, new trends in the development of mass psychogenic illness and a new type of mass psychogenic illness, MSMI, proposed by researchers are reviewed. Finally, two important studies from the past decade are reviewed. The findings of two studies, the inducibility of mass psychogenic illness and hypnotizability, an important predictor to the emergence of cases of mass psychogenic illness, are also presented. Besides, some implications for future research into mass psychogenic illness are given through the review.

77.1 Contagium of Somatic Psychiatric Symptoms Across History Before Social Media

The objectives are to: 1) define mass hysteria or mass psychogenic illness and functional neurological disorder including presenting the characteristics and factors that lead to this phenomenon throughout history; 2) understand how mental health symptoms spread before social media; 3) discuss prominent historical examples of mass hysteria and their spread; and 4) gain a better understanding of the precipitants that lead to mass hysteria events and their outcomes for individuals and for public health.

Studying cognitive function in patients with a long-standing diagnosis of SWEDD

IntroductionThe cognitive profile of patients with longstanding clinical Parkinsonism possessing scans without evidence of dopaminergic deficit (SWEDD) remains unclear from previous studies. MethodsWe studied 47 patients recruited in the Parkinson's Progression Markers Initiative with SWEDD as baseline diagnosis. They were subdivided by final clinical diagnoses after a 2-year follow-up period into 25 patients with either clinical evidence of Parkinson's Disease (PD) or unclassified parkinsonism and normal SPECT imaging (“true SWEDDs”), 6 patients with a psychogenic illness exhibiting Parkinsonism, 6 patients who had phenoconverted to PD based on reduced striatal dopaminergic activity on imaging, and 10 patients with another tremulous condition. Cognitive symptoms were compared between these subgroups, as well as with 62 PD patients and 195 healthy controls (HCs), at baseline and follow-ups. ResultsA significant difference in working memory was found between true SWEDDs and HCs (P = 0.009), but not true SWEDDs and PD patients (P = 0.432), nor PD patients and HCs (P = 0.154). The prevalence of attentional impairment was also significantly different between the three groups (P < 0.001). SWEDD subgroups possessed similar cognitive symptoms irrespective of their final clinical diagnosis. Psychogenic, phenoconverted and tremulous SWEDDs also possessed stable cognitive symptoms over the 2-year period whilst true SWEDDs, PD patients and HCs experienced significant changes in working memory. ConclusionsOur results, particularly relating to working memory and attention, add to the knowledge of other true SWEDD non-motor symptoms to facilitate earlier diagnosis and improved management strategies for these patients.

The origins of catatonia – Systematic review of historical texts between 1800 and 1900

Since January 1st 2022, catatonia is (again) recognized as an independent diagnostic entity in the 11th revision of the International Classification of Diseases (ICD-11). This is a relevant time to systematically review how the concept of catatonia has evolved within the 19th century and how this concept changed under the influence of a wide variety of events in the history of psychiatry. Here, we systematically reviewed historical and modern German and English texts focusing on catatonic phenomena, published from 1800 to 1900. We searched five different electronical databases (https://archive.org, www.hathitrust.org, www.books.google.de, https://link.springer.com and PubMed) and closely reviewed 60 historical texts on catatonic symptoms. Three main findings emerged: First, catatonic phenomena and their underlying mechanisms were studied decades before Karl Ludwig Kahlbaum's catatonia concept of 1874. Second, Kahlbaum not only introduced catatonia, but, more generally, also called for a new classification of psychiatric disorders based on a comprehensive analysis of the entire clinical picture, including the dynamic course and cross-sectional symptomatology. Third, the literature review shows that between 1800 and 1900 catatonic phenomena were viewed to be ‘located’ right at the interface of motor and psychological symptoms with the respective pathophysiological mechanisms being discussed. In conclusion, catatonia can truly be considered one of the most exciting and controversial entity in both past and present psychiatry and neurology, as it occupies a unique position in the border territory between organic, psychotic and psychogenic illnesses.

Psychogenic epidemic - mass hysteria phenomena in Portugal

IntroductionMass hysteria also called mass psychogenic illness (MPI), defined as a social phenomenon, consists of collective anxiety due to a perceived threat and can culminate in a cascade of symptoms suggestive of organic disease without an identifiable cause. Its history dates back to the 14th century and impacts people from all cultures and regions of the world. Before the 20thcentury, MPI emerged across Europe, often in socially isolated convents, in highly stressful environments.Objectives The aim of this study is to explore the available literature on mass hysteria phenomena in Portugal, historical origins, applications and eventual position in modern psychiatric semiology.MethodsNon-systematic review of literature published in Medline/Pubmed. Search terms included: mass hysteria, nocebo, groupthink, emotional contagion.Results In Portugal two great phenomena of mass hysteria were described. In 1917, the “sun miracle” occurred, where thousands of individuals reported having seen the sun rotating in the sky and changing its size and colours. Years later, more than 300 students from 14 schools described the same symptoms: dizziness, dyspnea and rash, without an identifiable cause. In common these young people had “sugar strawberries”. In May 2006, the young people in the television series were infected with a vírus, and clinical picture was similar to that presented by young people in real life. For the first time, a fictional illness on television triggered an illness in real life.ConclusionsMore studies should be carried out on these phenomena as their early recognition can have a tremendous impact on the ease of identification, diagnosis and treatment.DisclosureNo significant relationships.

Predictors of mass psychogenic illness in a junior secondary school in rural Botswana: A case control study.

BackgroundIn March 2019, students at Lempu Secondary School in Kweneng District, Botswana displayed symptoms including headache, abnormal leg movements and difficulty walking. Within days, 133 students were admitted to Scottish Livingstone Hospital where mass psychogenic illness (MPI) was diagnosed.AimTo identify predictors of this illness.SettingKweneng West District, Botswana.MethodsThis was a case control study using interviewer-administered questionnaires. Cases were students who displayed MPI symptoms from the 2nd of March to the time of the interviews or who were admitted with MPI diagnosis. Analysis was restricted to female students. Logistic regression was used to generate odds ratios. A p value of < 0.05 was considered to demonstrate significant association between variables.ResultsInterviews were conducted with 142 cases and 202 controls. The median age was 15 years. Most of the cases (95.8%) were boarding girls. Residence in school campus (AOR 13.2), history of evaluation by psychologist and/or social worker (AOR 2.6), history of traumatic events (AOR 1.8), contact with sick peers (AOR 2.3) and contact with spiritual healer (AOR 2.0) were independent predictors of MPI. Additionally, perception of adequate security in the dormitories (AOR 0.3) and perception of poor lighting (AOR 6.8) were significant predictors of MPI amongst boarding girls.ConclusionThe outbreak in Lempu Community Junior Secondary School (CJSS) was typical of mass psychogenic illness affecting mainly boarding girls and was associated with psychological and environmental risk factors. Changing the boarding environment and continuous psychological support are key to preventing future outbreaks. Interventions should also target the identified risk factors.

Mass Hysteria among Beneficiary Students of the School-Feeding Program in Addis Ababa, Ethiopia.

Mass hysteria is described as the rapid spread of conversion disorder without organic basis among a group of people. Mass hysteria can occur in work place and commonly in schools. There are usually some factors attributable to the episode; however, the lack of a pathogen upon investigation is a fundamental characteristic. We are reporting an episode of mass hysteria from two schools in Addis Ababa, Ethiopia. Clinical record, laboratory investigation, toxicology study from the food and psychiatric evaluations. On November 25, 2019 a total of 113 students were brought from two schools in Addis to Tikur Anbessa Specialized Hospital. Most were between the ages of 10 and 15 years and were female students. Their school breakfast of bread and marmalade was attributed as the cause of the episode; however only 49% of the students brought in had eaten the food. The majority complained of nausea and vomiting but most had normal physical finding; and their symptoms were resolved without treatment. The laboratory investigation on samples of blood and stool were negative for bacterial growth and food culture and toxicology were non-revealing. Most were reassured and few were given symptomatic treatment. This mass hysteric episode is similar to episodic reports from other school feeding programs in some Asian and African countries. The finding of this report is important for health care practitioners to consider mass psychogenic illness in case they face similar mass presentation without objective finding; and will help to avoid unnecessary costly investigations.

The tic in TikTok and (where) all systems go: Mass social media induced illness and Munchausen's by internet as explanatory models for social media associated abnormal illness behavior.

This paper explores the recent phenomenon of adolescents presenting en masse (both online and in clinical settings) with symptoms seemingly acquired from viewing illness-related content posted by social media influencers. The most frequently reproduced illnesses have included Dissociative Identity Disorder (DID) and Tourette Syndrome. It discusses evidence that the recent spate of new-onset, severe tics are a form of Mass Psychogenic Illness facilitated by social media networks (a phenomenon labeled Mass Social Media Induced Illness). It then suggests that many of those self-diagnosed with DID may be manifesting a similar, technologically-facilitated conversion phenomenon. It then explores another explanatory model: that these simulacra of DID and Tourette Syndrome may also arise via a mechanism more closely resembling social media facilitated Factitious Disorder. Similar presentations, of individuals falsifying cancer, have previously been labeled Munchausen's by Internet. It then proposes an overarching construct, Social Media Associated Abnormal Illness Behavior (SMAAIB), that is agnostic regarding phenomenology. Within this framework, it explores the ways in which de-commodifying attention, connection and care (measured once in appointments and admissions, now in 'likes' and 'shares') and obtaining a full picture of the patient's psychological, sociological and cultural grounding can offer deeper understanding and ultimately a path to wellness.

Turning suffering into side effects: Responses to HPV vaccination in Colombia

How do unpleasant post-vaccination symptoms become recognized as vaccine ‘side effects'? In this paper, we argue that it is not necessarily the logical outcome of scientific verification that it is said to be. The paper draws on an ethnographic study carried out in a small town, El Carmen de Bolivar, on Colombia's Caribbean coast from February through May 2019. In 2014, hundreds of girls in the town reported a range of mysterious symptoms following mass vaccination against the Human Papilloma Virus (HPV). Denying the girls' insistence that their symptoms were due to the vaccine, the official diagnosis was Mass Psychogenic Illness. Comparing these events with studies of controversial responses to other vaccines, we suggest that the pathway from post-vaccination symptoms to ‘side effects’ is cognitively and socially complex. In particular, it is context-dependent. Drawing on research in medical anthropology, sociology and STS, we argue that the official diagnosis was influenced by the subjects' marginal status; by a projection of the region's violent past onto individual inhabitants; by health professionals' commitment to a restricted notion of evidence (devaluing patients' own accounts); and by an institutional inability or unwillingness to stand against ‘global consensus’, which deems HPV safe.

Psychosomatic Pain? The Meanings of Musculoskeletal Affliction in Finnish Medicine, ca. 1950–2000

Abstract In recent decades, pain has received extensive attention from historians. However, the boundary work between organic and psychogenic pain has been less studied. To address the mind–body problem in the history of pain, this article examines how Finnish physicians in the latter half of the twentieth century have applied the psychosomatic framework to three painful conditions: rheumatoid arthritis, chronic backache and fibromyalgia. Through the interrelated case studies, it is argued that the medical discussion on musculoskeletal pain reflected social and economic interests and values that evolved in the course of the twentieth century. The psychogenic illness explanation compelled physicians to step outside the confines of biomedical rationale. Therefore, the descriptions of the ‘mind’ behind the ‘body’ render conspicuous for historians the values, moral norms and social expectations that underlie biomedicine.

The Dilemma, Conversion Disorder or Stiff Person Syndrome, a Case Report

The main objectives of this case study are 1. Clinicians facing symptoms that are difficult to interpret should exercise caution in diagnosing conversion disorder. 2. Increasing awareness about rare neurological conditions may appear as psychogenic illnesses. 3. Clinicians be advocate for their patients. Conversion disorder is a mental condition in which a person present with one or more symptoms of altered voluntary motor or sensory function, or other neurologic symptoms that cannot be explained by medical evaluation. Stiff person syndrome (SPS) is a disabling autoimmune central nervous system disorder characterized by progressive muscle rigidity, gait impairment, with superimposed painful spasms. SPS is commonly associated with high anti-glutamic acid decarboxylase (GAD) antibody titers. The dominant antigen recognized by these antibodies is the GABA-synthesizing enzyme GAD. Patient X, a 17-year-old Hispanic American female who presented to the Child and Adolescent Psychiatry Clinic with the complaint of ataxia & aphasia associated with anxiety. Patient was referred by the neurology clinic after they could not establish any organic cause of her ataxia or aphasia. After thorough evaluation at the child psychiatry clinic she was given the diagnosis of anxiety secondary to ataxia and aphasia and r/o Conversion Disorder. She was initiated treatment with sertraline for her anxiety. Her sertraline dose was increased gradually up to 100 mg daily. From the beginning the patient also received counseling & physical therapy. With these combination of treatments, patient's symptoms did not get any better. Her symptoms actually got worse over time. At this point, the Child Psychiatry Clinic sent a message to the neurology clinic for further evaluation of patient due to her progressive gait and speech impairments. The neurology clinic saw the patient again and did further testing. The patient was positive for high titers of anti-glutamic acid decarboxylase antibodies (Anti-GAD). At this point, the patient was given the diagnosis of Stiff Person Syndrome. Patient was admitted to the hospital for further management. She was treated with benzodiazepines, IV immune globulin, & steroid. Soon after discharge from the hospital, the patient was seen at the Child Psychiatric Clinic. The patient's mother reported, after the in-patient treatment, the patient's symptoms improved. It is essential for clinicians to look for neurologic & other general medical conditions while evaluating a patient with possible conversion disorder. A systematic review of 27 studies found that among 1466 patients initially diagnosed with conversion symptoms, the frequency of misdiagnosis was approximately 4 percent.References. BMJ. 2005;331(7523):989. Epub Oct 13. Childhood onset of stiff-man syndrome. JAMA Neurol. 2013;70(12):1531. J Neurol Neurosurg Psychiatry. 2015 Aug; 86(8):840-8. Epub 2014 Dec 15.

Morgellons Disease: The Spread of a Mass Psychogenic Illness via the Internet and Its Implications in Hand Surgery.

Somatic manifestations of mental illness sometimes occur in patients presenting to hand specialists. These conversion disorders can also occur in groups, a phenomenon known as "mass psychogenic illness." The increasing penetrance of the Internet and social media in modern society has greatly facilitated the interaction of patients with others with similar disorders. One example relevant to hand surgery is "Morgellons disease," a disorder popularized in 2002 and characterized by a firm belief in foreign material extruding from the skin, leading to nonhealing, self-inflicted ulcerations and excoriations. A series of 4 patients collected through an informal survey of hand surgeons regarding experience with Morgellons disease is reviewed and discussed. All patients in the series presented with a chief complaint of foreign material extruding from the hand. In 1 case, the complaint was made by a young patient's mother. In none of the patients were foreign bodies identified, although 2 patients demonstrated significant ulcerations and scars from self-excoriation. Three patients had a somatic condition affecting the hand or upper extremity, 1 directly related to self-excoriation and 2 unrelated. Treatments, workups, and ultimate outcomes varied among patients. Patients presenting with Morgellons disease often undergo multiple unnecessary tests and are at risk of inappropriate procedures. It is therefore important that providers have a compassionate understanding of the involved psychology. Herein, we offer an approach to the recognition of and treatment strategies for these patients.
