126-509: A "village psychiatrist", who believed that his words had power. From the 13th century, women with hysteria were exorcised, as it was believed that they were possessed by the devil. It was believed that if doctors could not find the cause of a disease or illness, it must be caused by the devil. At the beginning of the 16th century, women were sexually stimulated by midwives in order to relieve their symptoms. Gerolamo Cardano and Giambattista della Porta believed polluted water and fumes caused

189-470: A conversion diagnosis. Even if there is a clear antecedent trauma or other possible psychological trigger, it is still not clear exactly how this gives rise to the symptoms observed. Patients with medically unexplained neurological symptoms may not have any psychological stressor, hence the use of the term "functional neurologic symptom disorder" in DSM-5 as opposed to "conversion disorder", and DSM-5's removal of

378-545: A highly noted psychologist during the early 20th century, argued that symptoms arose through the power of suggestion, acting on a personality vulnerable to dissociation . In this hypothetical process, the subject's experience of their leg, for example, is split off from the rest of their consciousness, resulting in paralysis or numbness in that leg. Some support for the Freudian model comes from findings of high rates of childhood sexual abuse in conversion patients. Support for

441-416: A lack of appropriate care, and suffering for the patients. Eliot Slater , after studying the condition in the 1950s, stated: "The diagnosis of 'hysteria' is all too often a way of avoiding a confrontation with our own ignorance. This is especially dangerous when there is an underlying organic pathology, not yet recognised. In this penumbra we find patients who know themselves to be ill but, coming up against

504-518: A lack of sex causes complications in the uterus. Many Greeks believed it could be prevented and cured with wine and orgies . Hippocrates argued that a lack of regular sexual intercourse led to the uterus producing toxic fumes, causing it to move in the body. Therefore, he argued, all women should be married and enjoy a satisfactory sexual life. Donald Capps argues that the diseases Jesus allegedly healed , such as paralysis and blindness, were actually forms of conversion disorder. He describes Jesus as

567-566: A limitation in sexual functioning that was included in the DSM-4 was removed in the DSM-5 as well. The ICD-11 classifies conversion disorder as a dissociative disorder with unspecified neurological symptoms. Conversion disorder, originally known as Hysteria and now known as Functional Neurologic Symptom Disorder , presents symptoms following exposure to a certain stressor, typically associated with trauma or psychological distress . Usually,

630-414: A literature review of 121 studies established that this was not true, with publication bias the most likely explanation for this commonly held view. Although agitation is often assumed to be a positive sign of conversion disorder, release of epinephrine is a well-demonstrated cause of paralysis from hypokalemic periodic paralysis . Misdiagnosis does sometimes occur. In a highly influential study from

693-541: A medical explanation for the conditions cannot be found. Symptoms of conversion disorder usually occur suddenly. Conversion disorder is typically seen in people aged 10 to 35, and affects between 0.011% and 0.5% of the general population. Conversion disorder can present with motor or sensory symptoms including any of the following: Motor symptoms or deficits: Sensory symptoms or deficits: Conversion symptoms typically do not conform to known anatomical pathways and physiological mechanisms. It has sometimes been stated that

882-474: A study showing that they also occur in neurological disease. One such symptom, for example, is la belle indifférence , described in DSM-IV as "a relative lack of concern about the nature or implications of the symptoms". In a 2006 study, no evidence was found that patients with functional symptoms are any more likely to exhibit this than patients with a confirmed organic disease. In DSM-V, la belle indifférence

945-471: A traumatic or stressful event. There are certain populations that are considered at risk for conversion disorder, including people with a medical illness or condition, people with personality disorders or dissociative disorders . No biomarkers have yet been found to support the idea that conversion disorder is caused by a psychiatric condition. There has been much recent interest in using functional neuroimaging to study conversion. As researchers identify

Conversion disorder

1260-411: Is not uncommon for patients with neurological disease to also have conversion disorder. In excluding neurological disease, the neurologist has traditionally relied partly on the presence of positive signs of conversion disorder, i.e. certain aspects of the presentation that were thought to be rare in neurological disease but common in conversion. The validity of many of these signs has been questioned by

1323-816: Is often thought that the frequency of conversion may be higher outside of the West, perhaps in relation to cultural and medical attitudes, evidence of this is limited. A 2007 community survey of urban Turkey found a prevalence of 5.6%. Many authors have found occurrence of conversion to be more frequent in rural, lower socio-economic groups, where technological investigation of patients is limited and people may know less about medical and psychological concepts. In recent surveys of conversion disorder, females predominate, with between two and six female patients for every male. Some research suggests however that this gender disparity may be confounded by higher rates of violence against women. Conversion disorder may present at any age, but

1386-549: Is only possible to those who come to their task in a spirit of humility. In the main the diagnosis of 'hysteria' applies to a disorder of the doctor–patient relationship. It is evidence of non-communication, of a mutual misunderstanding   ... We are, often, unwilling to tell the full truth or to admit to ignorance   ... Evasions, even untruths, on the doctor's side are among the most powerful and frequently used methods he has for bringing about an efflorescence of 'hysteria'". The onset of conversion disorder often correlates to

1449-474: Is rare in children younger than ten or in the elderly. Studies suggest a peak onset in the mid-to-late 30s. The first evidence of conversion disorder dates back to 1900 B.C., when the symptoms were blamed on the uterus moving within the female body. The treatment varied "depending on the position of the uterus, which must be forced to return to its natural position. If the uterus had moved upwards, this could be done by placing malodorous and acrid substances near

1512-411: Is that the symptoms may have been evolutionarily advantageous during warfare. A non-combatant with these symptoms signals non-verbally, possibly to someone speaking a different language, that she or he is not dangerous as a combatant and also may be carrying some form of dangerous infectious disease . This can explain that conversion disorder may develop following a threatening situation, that there may be

1575-481: Is the most common treatment, with a 13% improvement rate. Empirical studies have found that the prognosis for conversion disorder varies widely, with some cases resolving in weeks, and others enduring for years or decades. There is also evidence that there is no cure for conversion disorder, and that although patients may go into remission they can relapse at any point. Many patients can get rid of their symptoms with time, treatments and reassurance. Information on

1764-400: Is unclear what proportion of the unexplained symptoms are actually due to the disorder. In 1976, large scale psychiatric registers in the U.S. and Iceland found incidence rates of 22 and 11 newly diagnosed cases per 100,000 person-years, respectively. In 2002, some estimates claim that in the general population, between 0.011% and 0.5% of the population have conversion disorder. Although it

1827-421: The 1960s, Eliot Slater demonstrated that misdiagnoses had occurred in one third of his 112 patients with conversion disorder. Later authors have argued that the paper was flawed. A 2005 meta-analysis has shown that misdiagnosis rates since that paper was published are around four percent, the same as for other neurological diseases.

2646-477: The disorder. Freud's model suggested the emotional charge deriving from painful experiences would be consciously repressed as a way of managing the pain, but that the emotional charge would be somehow "converted" into neurological symptoms. Freud later argued that the repressed experiences were of a sexual nature. As Peter Halligan comments, conversion has "the doubtful distinction among psychiatric diagnoses of still invoking Freudian mechanisms". Pierre Janet ,

2709-616: The dissociation model comes from studies showing heightened suggestibility in patients with conversion disorder. Critics argue that it can be challenging to find organic pathologies for all symptoms, and so the practice of diagnosing patients with such symptoms as having hysteria led to the disorder being meaningless, vague and a sham diagnosis, as it does not refer to any definable disease. Throughout its history, many patients have been misdiagnosed with hysteria or conversion disorder when they had organic disorders such as tumors , epilepsy , or vascular diseases . This has led to patient deaths,

2898-450: The frequency of conversion disorder in the West is limited, in part due to the complexities of the diagnostic process. In neurology clinics, the reported prevalence of unexplained symptoms among new patients is very high, between 30 and 60%. However, diagnosis of conversion disorder typically requires an additional psychiatric evaluation, and since few patients will see a psychiatrist, it

2961-477: The hysteria phenomenon as there was no evidence to prove its existence. Sigmund Freud referred to the condition as both hysteria and conversion disorder throughout his career. He believed those with the condition could not live in a mature relationship, and that those with the condition were unwell in order to achieve a "secondary gain", in that they are able to manipulate their situation to fit their needs or desires. He also found that both men and women could have

3024-500: The mechanisms which underlie conversion symptoms, it is hoped they will enable the development of a neuropsychological model. A number of such studies have been performed, including some which suggest the blood-flow in patients' brains may be abnormal while they are unwell. The studies have all been too small to be confident of the generalisability of their findings, so no neuropsychological model has been clearly established. An evolutionary psychology explanation for conversion disorder

3087-686: The need for a psychological trigger. The change of name in the DSM-5 also came with a change of criteria. there was a removal of connection to sexual functioning as well as relation to any other medical condition. There was also an added connection to social and occupational functioning. While conversion symptoms are not a normal responses to stress, taking measures to better manage psychological stress can help relieve symptoms. Treatments for conversion syndrome include hypnosis, psychotherapy, physical therapy, stress management, and transcranial magnetic stimulation . Treatment plans will consider duration and presentation of symptoms and may include one or multiple of

3150-572: The physical symptoms of the syndrome affect the senses or movement. Common symptoms include blindness , partial or total paralysis , inability to speak , deafness , numbness , difficulty swallowing , incontinence , balance problems , non-epileptic seizures , tremors , and difficulty walking. The symptom of feeling unable to breathe, but where the lips are not turning blue, can indicate conversion disorder or sleep paralysis . Sleep paralysis and narcolepsy can be ruled out with sleep tests . These symptoms are attributed to conversion disorder when

3213-448: The presenting symptoms tend to reflect the patient's own understanding of anatomy and that the less medical knowledge a person has, the more implausible are the presenting symptoms. However, no systematic studies have yet been performed to substantiate this statement.

3528-434: The symptoms of hysteria. Towards the end of the century, the role of the uterus was no longer thought central to the disorder, with Thomas Willis discovering that the brain and central nervous system were the cause of the symptoms. Thomas Sydenham argued that the symptoms of hysteria may have an organic cause. He also proved the uterus is not the cause of symptoms. In 1692, in the U.S. town of Salem, Massachusetts , there

In Greek mythology, hysteria , a similarly described condition, was thought to be caused by a lack of orgasms, uterine melancholy, and not procreating. Plato , Aristotle , and Hippocrates believed that

3780-543: Was a reported outbreak of hysteria. This led to the Salem witch trials , where women who were accused of being witches had symptoms such as sudden movements, staring eyes, and uncontrollable jumping. During the 18th century, there was a move from the idea of hysteria being caused by the uterus to it being caused by the brain. This led to an understanding that it could affect both sexes. Jean-Martin Charcot argued that hysteria

3843-490: Was caused by "a hereditary degeneration of the nervous system, namely a neurological disorder". In the 19th century, hysteria moved from being considered a neurological disorder to being considered a psychological disorder, when Pierre Janet argued that "dissociation appears autonomously for neurotic reasons, and in such a way as to adversely disturb the individual's everyday life". As early as 1874, doctors including W. B. Carpenter and J. A. Omerod began to speak out against

3906-412: Was removed as a diagnostic criterion. Another feature thought to be important was that symptoms tended to be more severe on the non-dominant, usually left side of the body. There have been a number of theories about this, such as the relative involvement of cerebral hemispheres in emotional processing, or more simply, that it was "easier" to live with a functional deficit on the non-dominant side. However,
