Pseudologia fantastica: definition and position in relation to axis I and axis II psychiatric disorders

Pseudologia fantastica, also known as mythomania or pathological lying, is a psychiatric phenomenon that has been recognised for over a hundred years. By analysing two case studies and by searching the literature for relevant articles we aim to define the concept clearly and to ascertain whether pseudologia fantastica should be considered as a symptom of a psychiatric disorder or whether it should be considered as a separate entity.     

A case of factitious homicidal ideation

Homicidal ideation is often fabricated or embellished by psychiatric patients in both the emergency room and inpatient settings. Typically, this symptom is malingered to achieve short-term hospital admission and temporary relief from complications of substance abuse, homelessness, and illicit activities. Very rarely, a patient may feign homicidal intent for the primary purpose of remaining in the role of patient (factitious disorder). Although factitious disorder with psychological symptoms has been described in a variety of circumstances, the psychiatric literature lacks any reports of factitious homicidal ideation. This is a report on the case of a patient who was civilly committed on numerous occasions for protracted periods based solely on his self-professed homicidal ideation. The case raises both forensic and clinical questions and reinforces the authors' belief that further investigation is needed to develop more sophisticated methods of detection, evaluation, and treatment of factitious disorder with psychological symptoms.     

Factitious disorders with psychological symptoms.

BACKGROUND: Factitious disorders with psychological symptoms have been underdiagnosed and hence undertreated. Historically, the literature has focused on factitious disorder with physical symptoms, particularly Munchausen's syndrome. METHOD: The authors report three cases of factitious disorder with psychological symptoms that had diverse clinical presentations. RESULTS: Two of the patients had features of a psychiatric Munchausen's syndrome--being middle-aged, aggressive men who falsified their symptoms, treatments, and backgrounds. The third patient was a younger woman with comorbid substance abuse, dysthymia, and borderline personality disorder. CONCLUSION: The authors feel that there is a need for refinement of diagnostic criteria, greater awareness, and evaluation of treatment approaches for this condition.     

Factitious disorder on an inpatient psychiatry ward

The authors present 6 cases of factitious disorder seen on a general adult inpatient psychiatry unit of a university hospital. They review the clinical features of this disorder and suggest that factitious disorder is much more prevalent among psychiatric inpatients than is commonly recognized. Strategies to assist in the diagnosis and management this disorder are detailed.     

Conversion syndromes in neurology. A psychopathological and psychodynamic differentiation of conversion disorder, somatization disorder and factitious disorder

Conversion syndromes are frequent among medically unexplained somatic symptoms in neurology. A careful differential diagnosis must be carried out in a psychiatric consultation service. In a prospective study lasting for over four years 169 patients with pseudoneurological signs of conversion were included. From a clinical point of view the following conversion syndromes were presented: astasia/abasia: 27.2%, paresis/plegia: 24.3%, aphonia: 1.8%, hyp-/anaesthesia: 21.9%, blindness: 5.3%, non-epileptic seizures: 19.5%. According to the diagnostic criteria of DSM-III-R three subgroups were differentiated: conversion disorder (n = 132), somatisation disorder (n = 28), factitious disorder (n = 9). Intermittent courses of illness were prevailing in conversion disorder, whereas chronic courses predominated in the other two subgroups. High rates of psychiatric comorbidity were typical signs of somatisation disorder. Frequent autodestructive motives (suicidality, deliberate and covert self-harm, chronic pain, high rate of operations) in illness behaviour had to be registered in somatisation and factitious disorder. Both subgroups were characterised by frequent traumatic events during early development. Important socio-economic aspects of illness behaviour above all in somatisation and factitious disorder were underlined. The results are discussed in terms of psychiatric differential diagnosis and psychiatric comorbidity, psychodynamic evaluation, illness behaviour and therapeutic options in a C/L-service.     

Munchausen's syndrome: a reconceptualization of the disorder

The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, third edition (DSM-III) delineates three categories of factitious disorders: chronic with physical symptoms (Munchausen's syndrome); factitious disorder with psychological symptoms; and other factitious disorders with physical symptoms. Munchausen's syndrome served as the prototype for all factitious disorders at the time DSM-III was drafted, partly due to the disproportionate attention given to this variant of the disorder. Clinical experience suggests that existing categories do not adequately provide for commonly seen forms of factitious illness. It is now recognized that factitious disorder is the result of a complex interaction of personality factors and psychosocial stressors that often present with both medical and psychiatric symptomatology. Proposed changes in the revised edition of the diagnostic manual DSM-III-R include separate categories of factitious disorder with psychological, physical, and both psychological and physical symptoms. A case report of a patient for whom extensive records and thorough psychological assessment were available is exemplary of a more common course of the disorder (both psychological and physical symptoms) that by current classification would be considered "atypical." A reconceptualization of the disorder that gives emphasis to course and clinical features is suggested.     

Psychiatric and behavioral correlates of factitious blindness

In factitious disorder, an individual feigns, exaggerates, or actually self-induces physical or psychiatric illness to achieve ends such as mobilizing care and concern, ventilating aggression, diminishing guilty feelings, or gratifying dependency wishes. We present 2 new cases of factitious binocular blindness, which has rarely been reported but readily illustrates the dramatic range of factitious illness behaviors. Psychiatric and behavioral correlates culled from these cases include extravagant claims about the impairment and ludicrous claims for nonvisual sensory abilities. These patients typically refuse psychiatric care, but earlier detection can help abort the illness deceptions and forestall iatrogenic complications.     

Falsifications in the psychiatric history: a differential diagnosis

Several types of falsification may be encountered in the clinical setting, including lies, pseudologia fantastica, delusions and confabulations. I will review these phenomena in the psychopathology literature and propose five criteria to facilitate classification of a falsification. I will then present case histories that illustrate the relationship between the type of falsification and the clinical psychiatric diagnosis.     

Pseudologia fantastica in the borderline patient

An infrequently described clinical feature sometimes associated with borderline personality disorder is pseudologia fantastica, or pathological lying. The author describes four cases of pseudologia fantastica in borderline patients. Clinical, forensic, and treatment implications of this disorder are discussed.     

Factitious disorder as repeated diabetic ketoacidosis: a case report

Factitious disorder is a challenging entity, both in diagnosis and treatment. The clinical presentation is variable in feigned symptoms and spans virtually all organ systems. The diagnostic criteria are simple, yet making the diagnosis is often complicated and can be delayed by focusing on the urgent or readily observable diagnosis. In this article, the authors present a case of factitious diabetic ketoacidosis resulting from the deliberate withholding of exogenous insulin. This particular case is dissected in order to portray the underlying psychopathology. In doing so, the authors illustrate how a patient with factitious disorder might fulfill unmet, presumably unrealized needs. The authors also discuss the diagnostic criteria and treatment strategies of factitious disorder, both of which are of considerable debate within the psychiatric community.     

A case report of comorbid eating disorder and factitious disorder

A review of the literature on comorbid eating disorder and factitious disorder reveals that they are very rare. In this report the authors present the case of a 26-year-old Japanese female, who, in the midst of treatment for eating disorder, was found to be fabricating her physical symptoms, by injecting unclean water into her intravenous bottle. As a result she was diagnosed with factitious disorder.     

Epileptic Munchausen's syndrome: a form of pseudoseizures distinct from hysteria and malingering

A young woman with seizures and status epilepticus sought and obtained hospitalization in at least 25 hospitals in the province of Quebec between 1980 and 1987. She was thought to have uncontrolled epilepsy; her treatment led to intoxication with anticonvulsants and once to anesthesia for three consecutive periods of 7 days each. The nonepileptic nature of her attacks was proven and a diagnosis of Munchausen's syndrome made. She was transferred to a psychiatric center where she committed suicide. We found no documented cases of epileptic chronic factitious disorder in the literature.     

Dual factitious disorder

The DSM-III classification of factitious disorders encourages artificial separation into disorders with physical and those with psychologic symptoms. Despite documented examples of similar patients who present with psychiatric complaints, Munchausen's syndrome is usually considered a form of chronic factitious physical disorder. Three patients with both factitious physical and psychologic symptoms are presented. These patients illustrate the importance of focusing on the fundamental behavior of assuming the patient role, rather than on the specific category of symptoms. We recommend that the category of symptoms be used as a modifying statement, rather than defining separate disorders.     

A case of factitious disorder involving menstrual blood smeared on the face

This article presents a case of factitious disorder in which a female smeared menstrual blood on her face. The patient was admitted to our otolaryngology clinic complaining of bleeding from the mouth, nose, ears and eyes. This event reportedly occurred three to four times on a daily basis. She acknowledged nine prior admissions to different specialists over the last two years. Following psychiatric consultation, we diagnosed factitious disorder with predominantly physical signs and symptoms. She was started on Fluoxetine 20 mg/day and supportive interviews were organized. After diagnosis, we observed that her symptoms decreased over two months. The symptoms did not reoccur three to nine months after treatment. This case report outlines two important features. The first is that a case of this type has not been reported before, and the second feature is that this case demonstrates the effect of cultural factors greatly different from those seen in classical factitious disorder.     

Psychogenic movement disorders

All varieties of movement disorders may be mimicked by a psychogenic disorder, most commonly tremor, dystonia, and myoclonus. Approximately 3% of patients seen in specialty clinics have a psychogenic movement disorder (PMD). The diagnosis of a PMD depends on not just ruling out an organic movement disorder, but moreover, recognizing features from the history and examination that are inconsistent or incongruous with an organic movement disorder. Most PMDs represent a conversion disorder, sometimes as part of a somatoform disorder; less common diagnoses include a factitious disorder or malingering. Co-morbid psychiatric illness is prevalent in patients with PMD including depression, anxiety, and personality disorders. Many PMDs remain chronic, but a multidisciplinary approach centering on psychiatric intervention can be successful. A shorter duration of symptoms and a co-existent treatable psychiatric disorder portend a better prognosis, whereas compensation and pending litigation are associated with a poorer prognosis.     

Factitious AIDS in a psychiatric inpatient

This article reports the case of a 28 year-old female presenting to a psychiatric inpatient unit with depression and a history of acquired immune deficiency syndrome (AIDS). Although medical assessment was negative for AIDS, psychiatric evaluation and psychological testing were consistent with a presentation of factitious disorder. This case illustrates the need to be on the alert for individuals admitted to psychiatric units who report they have AIDS or its related conditions.     

The Munchausen patient in a forensic facility

The many reports in the literature of chronic factitious illness (Munchausen's Syndrome) have emphasized the difficulty of treating these patients because of their propensity to leave medical facilities as soon as the factitious nature of their symptoms is discovered, and because of their disinclination to accept psychiatric help. The authors report on their treatment of such a patient who was incarcerated for over ten years under a criminal commitment, and discuss methods for overcoming resistances to treatment in Munchausen's patients.     

Psychocutaneous disorders

Dermatologic conditions are commonly associated with psychiatric sequella, eg, urticaria, alopecia, psoriasis, or acne. Moreover, the onset and course of dermatologic disorders may be significantly influenced by stress, emotional disturbances, or psychiatric disorder. Compulsions involving the skin, excoriations, or hair pulling (trichotillomania) are the more frequently encountered problems. In some cases, skin conditions are self-induced or reflect signs or symptoms of an underlying psychiatric disorder, including psychosis or obsessive-compulsive disorder. Additionally, skin lesions have been frequently described in case reports of factitious dermatitis. Finally, adverse effects of psychotropic drugs may cause dermatologic side effects, mostly idiosyncratic skin eruptions. These problems are discussed with emphasis on clinical features, comorbidity, and psychiatric management.
