In social psychology, hysterical contagion occurs when people in a group show signs of a physical problem or illness, when in reality there are psychological and social forces at work.
Hysterical contagion is a strong form of social contagion; the symptoms can include those associated with clinical hysteria.
In 1977 Frieda L. Gehlen offered a revised theory of hysterical contagion that argues that what is actually contagious is the belief that showing certain characteristics will "entitle one to the secondary benefits of the sick role." [1] It may be an unconscious decision on the part of the individual. This approach posited by Gehlen is believed[ by whom? ] to be more consistent with the existing knowledge of the contagion process and the theoretical approaches to collective behavior.
The June bug epidemic serves as a classic example of hysterical contagion. In 1962 a mysterious disease broke out in a dressmaking department of a US textile factory. The symptoms included numbness, nausea, dizziness, and vomiting. Word of a bug in the factory that would bite its victims and cause them to develop the above symptoms quickly spread. [2]
Soon sixty-two employees developed this mysterious illness, some of whom were hospitalized. The news media reported on the case. After research by company physicians and experts from the US Public Health Service Communicable Disease Center, it was concluded that the case was one of mass hysteria.
While the researchers believed some workers were bitten by the bug, anxiety was probably the cause of the symptoms. No evidence was ever found for a bug which could cause the above flu-like symptoms, nor did all workers demonstrate bites.
Workers concluded that the environment was quite stressful; the plant had recently opened, was quite busy and organization was poor. Further, most of the victims reported high levels of stress in their lives. Social forces seemed at work too.
Of the 62 employees that reported symptoms, 59 worked on the first shift, 58 worked in the same area, and 50 of the 62 cases occurred in the two consecutive days after the media supposedly “sensationalized” the event. Most of the employees who became sick took time off to recuperate.
A disease is a particular abnormal condition that negatively affects the structure or function of all or part of an organism, and that is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies and autoimmune disorders.
Histrionic personality disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive attention-seeking behaviors, usually beginning in early childhood, including inappropriate seduction and an excessive desire for approval. People diagnosed with the disorder are said to be lively, dramatic, vivacious, enthusiastic, extroverted and flirtatious.
Hysteria is a term used colloquially to mean ungovernable emotional excess and can refer to a temporary state of mind or emotion. In the 19th century, hysteria was considered a diagnosable physical illness in women. It is assumed that the basis for diagnosis operated under the belief that women are predisposed to mental and behavioral conditions; an interpretation of sex-related differences in stress responses. In the 20th century, it shifted to being considered a mental illness. Many influential people such as Sigmund Freud and Jean-Martin Charcot dedicated research to hysteria patients.
Sick building syndrome (SBS) is a condition in which people in a building suffer from symptoms of illness or become infected with chronic disease from the building in which they work or reside. The outbreaks may or may not be a direct result of inadequate cleaning or inappropriate cleaning methods. SBS has also been used to describe staff concerns in post-war brutalist-style buildings with misplanned building aerodynamics, defects in the construction materials or assembly process and-or inadequate maintenance. Certain symptoms tend to increase in severity with the time people spend in the building; often improving over time or even disappearing when people are away from the building. SBS is also used interchangeably with "building-related symptoms", which orients the name of the condition around patients' symptoms rather than a "sick" building. A 1984 World Health Organization (WHO) report suggested up to 30% of new and remodeled buildings worldwide may be subject of complaints related to poor indoor air quality. Other causes have been attributed to contaminants produced by outgassing of some types of building materials, volatile organic compounds (VOC), improper exhaust ventilation of ozone, light industrial chemicals used within, or lack of adequate fresh-air intake/air filtration.
Conversion disorder (CD), or functional neurologic symptom disorder, is a diagnostic category used in some psychiatric classification systems. It is sometimes applied to patients who present with neurological symptoms, such as numbness, blindness, paralysis, or fits, which are not consistent with a well-established organic cause, which cause significant distress, and can be traced back to a psychological trigger. It is thought that these symptoms arise in response to stressful situations affecting a patient's mental health or an ongoing mental health condition such as depression. Conversion disorder was retained in DSM-5, but given the subtitle functional neurological symptom disorder. The new criteria cover the same range of symptoms, but remove the requirements for a psychological stressor to be present and for feigning to be disproved. ICD-10 classifies conversion disorder as a dissociative disorder while DSM-IV classifies it as a somatoform disorder.
A factitious disorder is a condition in which a person, without a malingering motive, acts as if they have an illness by deliberately producing, feigning, or exaggerating symptoms, purely to attain a patient's role. People with a factitious disorder may produce symptoms by contaminating urine samples, taking hallucinogens, injecting fecal material to produce abscesses, and similar behaviour.
Ganser syndrome is a rare dissociative disorder characterized by nonsensical or wrong answers to questions and other dissociative symptoms such as fugue, amnesia or conversion disorder, often with visual pseudohallucinations and a decreased state of consciousness. The syndrome has also been called nonsense syndrome, balderdash syndrome, syndrome of approximate answers, hysterical pseudodementia or prison psychosis. The term prison psychosis is sometimes used because the syndrome occurs most frequently in prison inmates, where it may be seen as an attempt to gain leniency from prison or court officials. Psychological symptoms generally resemble the patient's sense of mental illness rather than any recognized category. The syndrome may occur in persons with other mental disorders such as schizophrenia, depressive disorders, toxic states, paresis, alcohol use disorders and factitious disorders. Ganser syndrome can sometimes be diagnosed as merely malingering, but it is more often defined as dissociative disorder.
The Mad Gasser of Mattoon was the name given to the person or people believed to be responsible for a series of apparent gas attacks that occurred in Mattoon, Illinois, during the mid-1940s. More than two dozen separate cases of gassings were reported to police over the span of two weeks, in addition to many more reported sightings of the suspected assailant. The gasser's supposed victims reported smelling strange odors in their homes which were soon followed by symptoms such as paralysis of the legs, coughing, nausea and vomiting. No one died or had serious medical consequences.
Dancing mania was a social phenomenon that occurred primarily in mainland Europe between the 14th and 17th centuries. It involved groups of people dancing erratically, sometimes thousands at a time. The mania affected adults and children who danced until they collapsed from exhaustion and injuries. One of the first major outbreaks was in Aachen, in the Holy Roman Empire, in 1374, and it quickly spread throughout Europe; one particularly notable outbreak occurred in Strasbourg in 1518 in Alsace, also in the Holy Roman Empire.
Female hysteria was once a common medical diagnosis for women, which was described as exhibiting a wide array of symptoms, including anxiety, shortness of breath, fainting, nervousness, sexual desire, insomnia, fluid retention, heaviness in the abdomen, irritability, loss of appetite for food or sex, (paradoxically) sexually forward behaviour, and a "tendency to cause trouble for others". It is no longer recognized by medical authorities as a medical disorder. Its diagnosis and treatment were routine for hundreds of years in Western Europe.
Medical explanations of bewitchment, especially as exhibited during the Salem witch trials but in other witch-hunts as well, have emerged because it is not widely believed today that symptoms of those claiming affliction were actually caused by bewitchment. The reported symptoms have been explored by a variety of researchers for possible biological and psychological origins.
Mass psychogenic illness (MPI), also called mass sociogenic illness, mass psychogenic disorder, epidemic hysteria, or mass hysteria, involves the spread of illness symptoms through a population where there is no infectious agent responsible for contagion. It is the rapid spread of illness signs and symptoms affecting members of a cohesive group, originating from a nervous system disturbance involving excitation, loss, or alteration of function, whereby physical complaints that are exhibited unconsciously have no corresponding organic causes.
Folie à deux, also known as shared psychosis or shared delusional disorder (SDD), is a psychiatric syndrome in which symptoms of a delusional belief, and sometimes hallucinations, are transmitted from one individual to another. The same syndrome shared by more than two people may be called folie à... trois ('three') or quatre ('four'); and further, folie en famille or even folie à plusieurs.
Social undermining is the expression of negative emotions directed towards a particular person or negative evaluations of the person as a way to prevent the person from achieving their goals. This behavior can often be attributed to certain feelings, such as dislike or anger. The negative evaluation of the person may involve criticizing their actions, efforts or characteristics. Social undermining is seen in relationships between family members, friends, personal relationships and co-workers. Social undermining can affect a person's mental health, including an increase in depressive symptoms. This behavior is only considered social undermining if the person's perceived action is intended to hinder their target. When social undermining is seen in the work environment the behavior is used to hinder the co-worker's ability to establish and maintain a positive interpersonal relationship, success and a good reputation. Examples of how an employee can use social undermining in the work environment are behaviors that are used to delay the work of co-workers, to make them look bad or slow them down, competing with co-workers to gain status and recognition and giving co-workers incorrect or even misleading information about a particular job.
The 1983 West Bank fainting epidemic occurred in late March and early April 1983. Researchers point to mass hysteria as the most likely explanation. Large numbers of Palestinians complained of fainting and dizziness, the vast majority of whom were teenage girls with a smaller number of female Israeli soldiers in multiple West Bank towns, leading to 943 hospitalizations.
Bourbon virus is an RNA virus in the genus Thogotovirus of the family Orthomyxoviridae, which is similar to Dhori virus and Batken virus. It was first identified in 2014 in a man from Bourbon County, Kansas, United States, who died after being bitten by ticks. The case is the eighth report of human disease associated with a thogotovirus globally, and the first in the Western hemisphere. As of May 2015, a case was discovered in Stillwater, Oklahoma and relatively little is known about the virus. No specific treatment or vaccine is available. The virus is suspected to be transmitted by ticks or insects, and avoidance of bites is recommended to reduce risk of infection. In June 2017 a 58-year-old female Missouri State Park employee died from an infection of the Bourbon virus after it had been misdiagnosed for a significant period of time.
Mad Travelers: Reflections on the Reality of Transient Mental Illnesses (1998) is a book by the Canadian philosopher of science Ian Hacking. The book provides an historical account of a medical condition that used to be known as fugue or mad travel. Fugue emerged as ‘a specific, diagnosable type of insanity’ (p. 8) in late nineteenth century France and then spread to Italy, Germany and Russia. The book was published in London nu: Free Association Books in, 1999. ISBN 9781853434556
Havana syndrome is an alleged set of medical symptoms with unknown causes experienced mostly abroad by U.S. government officials and military personnel. The symptoms range in severity from pain and ringing in the ears to cognitive difficulties and were first reported in 2016 by U.S. and Canadian embassy staff in Havana, Cuba. Beginning in 2017, more people, including U.S. intelligence and military personnel and their families, reported having these symptoms in other places, such as China, New Delhi, India, Europe, and Washington, D.C. The cause and validity of the illness have yet to be determined.
