The "Hysterical Psychosis" Dilemma: A Narrative Review.

BACKGROUND: Hysteria in its most severe expression may reach psychotic manifestations. Such symptomatology has been occasionally described by various authors starting from the 19th century and defined as "hysterical psychosis" (HP) by Hollender and Hirsch in 1964. Currently, diagnostic psychiatric manuals such as DSM and ICD do not include the diagnosis of HP, although this term is commonly used in clinical practice. This raises a well-known problem with case definition due to an inconsistent use of terminology. SUMMARY: Here, we propose a review of the literature that aims to highlight the clinical features of HP endorsed by the majority of authors, such as histrionic premorbid personality, acute reactive onset, short duration, altered state of consciousness, unstable delusions, typical hallucinations, labile mood, lack of flat affect. In the discussion, we focus on the differential diagnosis between HP and other diagnoses such as brief psychosis and schizophrenia, trying to point out aspects of distinction and continuity. KEY MESSAGES: The debate about this nosographic entity still remains a huge dilemma and needs further contributions.

Possible unusual presentation of opioid side effect in a child: a case report.

Atypical presentations are commonly encountered in the Pediatric intensive care unit (PICU) but having a high index of suspicion is crucial to prevent or treat severe and life-threatening conditions. This case describes the clinical presentation and course of a 14-month-old girl with congenital heart disease who was admitted to the PICU after cardiac repair and remained agitated, irritable, in hysteria and delirium despite adequate sedation. Different measures to relieve her condition were attempted but to no avail. All the common causes of this atypical presentation including pain, ventilator induced agitation, low cardiac output syndrome (LCOS), opioid side effects, toxicity, opioid induced neurotoxicity (OIN) as well as withdrawal syndrome were ruled out. However, the use of naloxone as a last resort after exhausting all the other options has led to immediate and successful reversal of her symptoms.

Hypnosis and suggestion as interventions for functional neurological disorder: A systematic review.

OBJECTIVE: Functional neurological disorder (FND) involves the presence of neurological symptoms that cannot be explained by neurological disease. FND has long been linked to hypnosis and suggestion, both of which have been used as treatments. Given ongoing interest, this review examined evidence for the efficacy of hypnosis and suggestion as treatment interventions for FND. METHOD: A systematic search of bibliographic databases was conducted to identify group studies published over the last hundred years. No restrictions were placed on study design, language, or clinical setting. Two reviewers independently assessed papers for inclusion, extracted data, and rated study quality. RESULTS: The search identified 35 studies, including 5 randomised controlled trials, 2 non-randomised trials, and 28 pre-post studies. Of 1584 patients receiving either intervention, 1379 (87%) showed significant improvements, including many who demonstrated resolution of their symptoms in the short-term. Given the heterogeneity of interventions and limitations in study quality overall, more formal quantitative synthesis was not possible. CONCLUSIONS: The findings highlight longstanding and ongoing interest in using hypnosis and suggestion as interventions for FND. While the findings appear promising, limitations in the evidence base, reflecting limitations in FND research more broadly, prevent definitive recommendations. Further research seems warranted given these supportive findings.

Affective Permeability: On Hysteria and Atmospheres.

BACKGROUND: Phenomenological literature has recently given much attention to the concept of atmosphere, which is the pre-individual affective tonality of the intersubjective space. The importance of atmospheres in psychopathology has been described for various disorders, but little is known about the interaction with hysteria. The aim of the present paper was to describe the psychopathology of hysteria from the angle of the phenomenon of atmosphere, focussing on the hysterical person's peculiar "affective permeability". SUMMARY: Hysterical people have difficulty defining themselves autonomously. As compensation, they adopt models transposed from the external environment such as social gender stereotypes or are influenced by the gaze and desire of others. They also possess a special sensitivity in perceiving the affectivity present in a given social situation, by which they are easily impressed and influenced. Their sensibility to environmental affectivity may allow them to take centre stage, assuming the postures and behaviours that others desire and that they sense by "sniffing" the atmosphere in which the encounter is immersed. Thus, a paradox may take place: sensibility is not mere passivity in hysteria but may become a tool for "riding" the emotional atmosphere and manipulating it. KEY MESSAGES: Affective permeability to environmental atmospheres and manipulation of the environment are the two sides of the same coin. This overlap of passive impressionability and active manoeuvring is necessary to be grasped in the clinical encounter with hysterical persons not to be submerged by their theatricality, that is, by the hyper-intensive expressivity of their feelings and behaviours.

The Most Hysterical Psychoanalyst.

This paper is an investigation into the prominence of hysteria in Lacan's work and the enduring significance of the diagnosis for contemporary practice. Beginning with Lacan's theory of neurosis, the importance of language, and symbolic functions, we will begin to understand why the hysterical symptom is the symptomatic structure par excellence. Lacan lauds hysteria as the neurosis in direct dialogue with a given historical moment, teaching the psychoanalyst where we are in the unfolding struggle between neurosis and civilization. He returned to the case of Dora throughout his twenty-eight years of teaching to refine his work. He even saw psychoanalysis as the progressive "hystericization" of the patient and depicted himself as an hysteric walking around on a stage, not knowing what he was saying, while attempting to teach the psychoanalysts. Lacan's reading of Dora seems to mark important shifts in his own life, from his beginning to write as a psychoanalyst, to being thrown out of the IPA, to struggling with his own school and the ensuing political eruptions in France in 1968. By tracking his elaboration of Dora we can witness the evolution of Lacan's work and how he uniquely positions the analyst in the transference.

Medicalizing disabled people's emotions-Symptom of a dis/ableist society.

The theoretical-conceptual article at hand explores how emotional discourses shape social relations by specifically focusing on the medicalization of disabled- and chronically ill-people's emotions. Medicalization is a concept from medical sociology that describes medicine's expansion into non-medical life areas, for instance into the realm of emotions, sometimes in order to challenge this expansion. The emotions of disabled people are often presented as a medicalized problem, rather than recognizing their embeddedness in a dis/ableist socio-cultural context. Such discourses instrumentalize feelings in order to individualize the responsibility for disability. For a contextualized and emancipatory approach, this study reviews papers on medicalized emotions from Disability Studies-a research program that can provide a rich archive of experiential accounts yet to be theorized through a comprehensive emotional perspective. The medicalization of disabled people's emotions can manifest in different ways: (1) In a dis/ableist society, able-mindedness is compulsory; i.e., we fail to question that a healthy mind is the norm and something to strive for unconditionally. This is also true on an emotional level; after all, some medical diagnoses are based on the wrong degree or temporality of emotionality. (2) Unpleasant feelings such as sadness are misunderstood as symptoms of impairment rather than effects of discrimination. (3) The expression of hurt feelings, e.g., related to discrimination, can easily be dismissed as hysterical. This assumption epistemologically disables patients. (4) Love and desire are delegitimized as fetish, for example, the desire for a disabled lover or the wish to start a family despite a chronic illness. The medicalization of disabled people's emotions individualizes and delegitimizes unpleasant emotions that emerge in a dis/ableist society. Different facets of medicalization enforce medical treatment instead, albeit in different ways. Disabled and sick people are cast as not feeling and desiring the right way, while hegemonic discourse prescribes psychological treatment against the effects of discrimination and bodily symptoms it cannot explain. Beyond the dismissal of disabled people's experience, adverse effects on healthcare delivery and health outcomes can be expected.

Phenomenon of Nightclub Shots: Mass Psychogenic Disease?

BACKGROUND: This article examines the possibility that the "nightclub shots" epidemic is a "mass psychogenic disease" phenomenon, by comparing the various cases of "mass sociogenic diseases" reported in the literature. We carried out a literature review on PubMed. The keywords used were "mass hysteria", "mass sociogenic disease", "mass psychogenic disease" and "epidemic of multiple unexplained symptoms". RESULTS: Our review of the literature revealed several elements common to the various "mass hysterias" we identified. These phenomena generally appear in a climate of anxiety specific to the era in which they occur, in this case the fear of bioterrorism in the 21st century. Symptoms are generally benign and transient, appearing and resolving easily without the identification of an organic cause. They usually occur in a small group of individuals, and more frequently in young people and women. The media can exacerbate the phenomenon. CONCLUSION: The phenomenon of epidemics of nightclub shots seems to fit into the common framework of "mass psychogenic diseases" identified in the literature. This diagnosis could therefore be evoked, in the absence of any other objective somatic explanation.

Myths and facts about functional neurological disorders: a cross-sectional study of knowledge and awareness among medical students and healthcare professionals in Iraq.

Background: Functional neurological disorder (FND) is a complex condition with neurological symptoms but no clear structural or biochemical explanation. Myths and misconceptions about FND can lead to misdiagnosis and inappropriate treatment. This study aimed to assess knowledge and common myths about FND among medical students and practitioners. Methods: Data were collected from 324 participants using a structured questionnaire. The questionnaire included demographics, general information about FND and myths about FND. Data were analysed using non-parametric tests and Spearman's r for correlations. Results: The majority of participants were clinical-years medical students (65.1%) and female (59.6%). Overall, knowledge about FND was limited, with a mean score of 42.3% of correct answers. Common myths included the belief that FND is a psychological disorder and that patients feign symptoms. Knowledge scores differed significantly among different grades/experience levels, with postgraduate practitioners having the highest scores. There was a positive correlation between knowledge scores and confidence in managing FND. Conclusion: This study highlights the prevalence of myths and misconceptions about FND among medical students and practitioners, emphasising the need for accurate education to improve diagnosis and management. Healthcare professionals should take a biopsychosocial approach to FND, considering the complex interplay between biological, psychological and social factors. Efforts to increase awareness and reduce stigma associated with FND are crucial for promoting better care. Targeted educational interventions may be beneficial to improve the understanding and management of FND among medical professionals.

[Validated care programs for patients with functional neurological disorders]. / Modèles de soins validés pour les patients souffrant de troubles neurologiques fonctionnels.

Functional neurological disorder (FND) is a common cause of persistent and disabling neurological symptoms. Diagnostic delay may lead to no treatment, inappropriate treatment or even iatrogenic symptoms. Yet, several treatments significantly reduce physical symptoms and improve functioning in FND patients even though not all patients respond to the currently available treatments. This review aims to describe the range of evidence-based rehabilitative and/or psychological therapeutic approaches available for FND patients. The most effective treatments are multidisciplinary and coordinated; using an outpatient or inpatient setting. Building a network of FND-trained healthcare professionals around the patient is an essential aspect of optimal patient management. Indeed, a supportive environment coupled with a collaborative therapeutic relationship improves understanding of FND and appears to help patients engage in appropriate treatments. Patients need to be invested in their own care and have to understand that recovery may depend on their commitment. The conventional treatment combines psychoeducation, physical rehabilitation and psychotherapy (cognitive and behavioral therapy, hypnosis, psychodynamic interpersonal therapy). Early referral of patients to physical therapy is recommended; however, the optimal parameters of treatment, duration and intensity are unknown and seem to vary with the severity and chronicity of symptoms. The goal is to minimize self-awareness by diverting attention or by stimulating automatically generated movements with non-specific and gradual exercises. The use of compensatory technical aids should be avoided as much as possible. Psychotherapeutic management should encourage self-evaluation of cognitive distortions, emotional reactions and maladaptive behaviors while empowering the patient in managing symptoms. Symptom management can use anchoring strategies to fight against dissociation. The aim is to connect to the immediate environment and to enrich one's sensoriality. The psychological interventions should then be adapted to the individual psychopathology, cognitive style and personality functioning of each patient. There is currently no known curative pharmacological treatment for FND. The pharmacological approach rather consists of progressively discontinuing medication that was introduced by default and that could lead to undesirable side effects. Finally, neurostimulation (transcranial magnetic stimulation, transcranial direct current stimulation) can be effective on motor FND.

[Overview of care management principles in functional neurological disorders]. / Synthèse des principes et schémas de prise en charge dans les troubles neurologiques fonctionnels.

After more than twenty years of academic research on functional neurological disorders (FND) throughout the world, a standardized care management strategy has emerged to allow a more adapted care offer to patients with FND, as close as possible to their experience and their needs. With regard to this special issue on FND in collaboration with L'Encéphale and at the initiative of the Neuropsychiatry section of the AFPBN (French Association of Biological Psychiatry and Neuropsychopharmacology), we would like to suggest a summary of all topics discussed in more detail in each article of this special issue, in order to facilitate its reading. We therefore cover the following themes: the initial contact with a patient with FND, the diagnostic process in favor of a positive diagnosis, the physiological, neural and psychological basis of FND, the diagnostic announcement (and its intangibles), the therapeutic patient education in FND, the general principles of therapeutic management through a personalized and multidisciplinary care program, and the validated therapeutic tools available according to the symptoms identified. This article is designed to be of broad interest on FND, supported by tables and figures showing the key points of all these steps, to keep an educational purpose at most. We hope that through this special issue, each health professional will be able to grasp this knowledge and this framework of care as easily and quickly as possible, in order to participate in the standardization of the care offer.

Dismissal informs the priorities of endometriosis patients in New Zealand.

Introduction: Endometriosis is a common condition with average delays to diagnosis in New Zealand of almost 9 years. Methods: In total, 50 endometriosis patients participated in anonymous, asynchronous, online group discussions about their priorities, and their experiences with the development of symptoms, seeking a diagnosis, and receiving appropriate treatment. Results: Higher subsidy of care was the top change endometriosis patients wanted, followed by more research funding. When asked to choose whether research should be focused on improving diagnosis or improving treatment methods, the results were evenly split. Within this cohort, patients highlighted that they did not know the difference between normal menstrual discomfort and pathological endometriotic pain. If, upon seeking help, medical practitioners classified their symptoms as "normal," these dismissals could instill doubt in patients, which made it more difficult for them to continue to seek a diagnosis and effective treatments. Patients who did not express dismissal had a significantly shorter delay from symptom onset to diagnosis of 4.6 ± 3.4 years vs. 9.0 ± 5.2 years. Conclusion: Doubt is a frequent experience for endometriosis patients in New Zealand, which was reinforced by some medical practitioners who were dismissive of their pain and thus prolonged the patient's delay to diagnosis.

From hysteria to gait dementia: History of the concept of astasia-abasia.

Paul Blocq (1860-1896) and his teacher Jean-Martin Charcot (1825-1893) introduced the expression "astasia-abasia" into medical terminology in 1888 to designate a pathology they believed to be caused by hysteria. This condition makes it impossible to remain erect and to walk, whereas the ability to move the legs while lying down remains normal. At the turn of the 20th century, and now almost exclusively, this motor disturbance is recognised as a syndrome with multiple possible organic causes, and now described as "higher-level gait disorder". After briefly mentioning earlier descriptions by other authors, I will review Charcot's Tuesday lessons in 1889 that covered astasia-abasia and elucidated the beginnings of the breakdown into organic aetiologies: medial-frontal and corpus callosum tumors, damage to the cerebellar vermis, lacunar state as described by Pierre Marie (1853-1940), Parkinson's disease, and Parkinson-plus syndrome. The long history of astasia-abasia reveals a cluster of neurologists, often emerging from oblivion herein and all of whom, through the precision of their clinical examinations and their pathophysiological findings, helped advance the understanding of the mechanisms by which human beings are the only erect, constantly bipedal mammals, whether immobile or walking.

The Body in Question in the Existence of Hysteric Persons: A Phenomenological Perspective.

The concept of hysteria, although apparently surpassed by contemporary nosographic classifications, continues to be talked about. Following Charbonneau's attempt to de-feminize and de-sexualize hysteria, clinical phenomenology can offer a perspective which, freed from stigma and prejudices through the suspension of judgement, allows us to understand hysteria not as a diagnostic category but as an existential position. In this sense, hysteria would be based on a hypo-sufficiency of the embodied self, which is not perceived as solid and continuous and needs external confirmations of its adequacy. According to the optical-coenaesthetic disproportion hypothesis, the hypo-sufficiency of the embodied self originates from the difficulty of experiencing one's body from the first-person perspective and from the consequent use of the gaze of others as a prosthesis to achieve a sense of selfhood and identity. Hysteric persons develop a mode of access to their corporeality mediated by visual representations - hence the theatricalization, centrality, and seductiveness of hysteric persons' behaviour. We suggest to call "figural body" the visual apprehension of one's body which tries to compensate for the weakness of coenaesthetic apprehension of the lived body. Over time, the figural body ends up superimposing itself on the immediate experience of the lived body. Placing itself on a representative register, this image conveys not only individual ghosts but also cultural aspects, social prejudices, gender stereotypes. Thus, the attempt to experience one's own body with the mediation of the other's gaze becomes an involuntary and unaware throwing of oneself into the meshes of representation that are necessarily alienating for the person. Hysterical persons remain stuck in their inability to access an experience of their body that is not figurative, alienating themselves in representations which always come from outside.

Functional Neurologic Disorders, disorders to be managed by neurologists, or are neurologists wandering in a dangerous field with inadequate resources?

In recent years, some neurologists reconsidered their approach to Medically Unexplained Symptoms and proposed Functional Neurologic Disorders (FND) as a new entity, claiming that neurology could offer alternative treatment options to the psychotherapies provided in psychiatry settings. FNDs, for this purpose, should include only the disorders listed as Conversion from the Somatic Symptom and Related Disorders (SSRD) group. The present review analyzes the rationale of this position and challenges the arguments provided for its support. The review also discusses the systematization of these disorders as provided by public health systems. It outlines risks stemming from economic support and public funding uncertainty, given their negligible epidemiological dimensions resulting from the parcellation of SSRD. The review underlines the unresolved issue of Factitious Disorders, which are in the same SSRD category of the international classification but are, nonetheless, overlooked by the theoretical proponents of the FND entity. Comorbidity with other psychiatric disorders is also analyzed. We propose a model that supports the continuum between different SSRD conditions, including Factitious Disorders. The model is based on the emergence of feigned death reflex and deception from frontal lobe dysfunction. Finally, the paper summarizes the wealth of historical psychiatric and psychodynamic approaches and critical reviews. The study also puts in context the categorization and interpretation efforts provided by the most eminent researchers of the past century.

A cross-sectional study on the personality traits of episodic and chronic migraine patients.

BACKGROUND: Migraine, is a common neurological disorder that may be associated with certain personality traits. This study aims to identify and compare the personality traits accompanying the clinical and sociodemographic profiles in migraine groups. METHODS: The study included a cohort of chronic, episodic migraine (CM - EM) and healthy controls (HC). Migraine was diagnosed according to the International Classification of Headache Disorders-3ß criteria. Age, gender, migraine-related disease duration, number of days with a headache each month, and headache intensity of the patients were recorded. The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was used to determine personality traits. RESULTS: The study groups were similar in terms of sociodemographic characteristics (70 CM, 70 EM, and 70 HC). The visual analog scale (VAS) score was significantly higher in CM (p < 0.05). No statistically significant difference was found between the groups concerning symptoms of migraine such as osmophobia, photophobia, phonophobia, and nausea (p > 0.05). When the personality traits were examined, the mean scores of the MMPI test results of migraine patients were found to be higher than healthy controls in line personality disorders (p < 0.05 for all personality traits). In CM patients, the 'hysteria' score was found to be higher in subgroup evaluation (p < 0.05). CONCLUSION: EM and CM patients had more evidence of personality disorders than healthy controls. CM patients had higher hysteria scores than EM patients. In addition to pain treatment, determining personality traits and providing appropriate management with a multidisciplinary approach can benefit both in terms of treatment, cost, and time.

[Borderline regions between neurology and psychiatry, focusing particularly on the functional neurological disorders].

Neurology in Japan did not develop from the separation of neuropsychiatry into neurology and psychiatry, which casts a shadow on the present situation of Japanese neurology. Functional neurological disorder (FND; hysteria) is a typical link between neurology and psychiatry. FND is a common disorder, which has been described from the ancient times and has also been the headstream of neurology. FND is not diagnosed by exclusion or by psychiatric causes, but should be actively diagnosed based on the neurological signs themselves (= positive signs of FND) as early as possible, with minimal ancillary tests. This opinion has been supported by the newest Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). Many positive signs have been described. Assessment by a neurologist also becomes a treatment.

What are the neural correlates of dissociative amnesia? A systematic review of the functional neuroimaging literature.

Aim: Dissociative amnesia is an emblematic psychiatric condition in which patients experience massive memory loss ranging from focal to global amnesia. This condition remains poorly understood and this review aims to investigate the neuroanatomical feature of this disease. Methods: We conducted a systematic review of the scientific literature available on PubMed, up to December 1, 2022, using a combination of keywords referring to dissociative amnesia. We included every scientific report involving patients undergoing a functional imaging procedure. Results: Twenty-two studies met our inclusion criteria (gathering 49 patients). Only one was a controlled study with a large sample. The other 21 were case reports and case series. In resting state, neuroimaging studies mostly showed a hypo-activated right inferolateral prefrontal cortex, associated with limbic hypoactivity and lesser activation of the hippocampal and para-hippocampal structures. The patients also presented abnormal patterns of cerebral activation when performing memory tasks. When testing recognition of memories from the amnestic period, patients showed increased activation across temporal areas (hippocampal and para-hippocampal gyri) and the limbic network. When trying to recollect memories from an amnestic period compared to a non-amnestic period, patients failed to activate these structures efficiently. Most of these patterns tended to return to normal when symptoms resolved. Conclusion: This review identified a paucity of controlled studies in the field of dissociative amnesia neuroimaging, which restricts the extrapolation of results. Patients with dissociative amnesia present a broad prefronto-temporo-limbic network dysfunction. Some of the brain areas implicated in this network might represent potential targets for innovative treatments.
