The authors discuss the case of a 36 year old woman who, for several years, has been delirious and who has shown signs of an affective disorder, alternatively suffering from hypomanic and depressive episodes. What is most interesting is that she expresses erotomaniac delusions while she is elated and persecutory delusions while she is depressed. The authors propose an psychopathological explanation for her disorder. 相似文献

BACKGROUND: Persecutory delusions are common in dementia. This study was undertaken to investigate the prevalence, associated factors, and characteristics of persecutory delusions in demented patients. METHOD: The sample population included 167 demented patients (DSM-III-R criteria) admitted to a geropsychiatric ward. Patients were assessed for the occurrence of any persecutory delusions since the onset of dementia. The content of persecutory delusions, the patients' response to the delusions, and any concomitant psychiatric symptoms were also explored. RESULTS: Of the 167 demented patients, 45 (26.9%) showed symptoms of persecutory delusions. Patients with persecutory delusions had a higher prevalence of other delusions, hallucinations, and physically aggressive behaviors. The deluded patients often thought that their caregivers were their persecutors and had a wide range of responses to their delusions. After they were hospitalized, many of these patients attacked medical staff and were uncooperative with treatment. CONCLUSION: Persecutory delusions are common in dementia of various types. Deluded patients often have vigorous responses to their delusions including physically aggressive behaviors and suicide attempts. Careful evaluation is needed to assess the potential for violent and suicidal behaviors in these patients. Medical staff should be alert to clinical strategies for handling the treatment of such patients when they become violent or uncooperative. 相似文献

BACKGROUND: Epidemiological studies have found that individuals who live in urban areas are at increased risk of developing psychosis. However it is unknown whether exposure to urban environments exacerbates psychotic symptoms in people who have a diagnosed psychotic disorder. The aim of the study was to examine the psychological and clinical effects of exposure to one specific deprived urban environment on individuals with persecutory delusions. It was predicted that the urban environment would affect emotional and reasoning processes highlighted in a cognitive model of persecutory delusions and would increase paranoia. METHOD: Thirty patients with persecutory delusions were randomised to exposure to a deprived urban environment or to a brief mindfulness relaxation task. After exposure, assessments of symptoms, reasoning, and affective processes were taken. Thirty matched non-clinical participants also completed the study measures to enable interpretation of the test scores. RESULTS: In individuals with persecutory delusions, exposure to the urban environment, rather than participation in a mindfulness task, increased levels of anxiety, negative beliefs about others and jumping to conclusions. It also increased paranoia. The individuals with persecutory delusions scored significantly differently from the non-clinical group on all measures. CONCLUSIONS: For individuals with psychosis, spending time in an urban environment makes them think more negatively about other people and increases anxiety and the jumping to conclusions reasoning bias. Their paranoia is also increased. A number of processes hypothesised in cognitive models to lead to paranoid thoughts are exacerbated by a deprived urban environment. Further research is needed to clarify which aspects of urban environments cause the negative effects. Methodological challenges in the research area are raised. 相似文献

The content and structure of delusions were compared in 30 women and 30 age-matched men with Schizophrenic Disorder. Men showed an excess of homosexual persecutory delusions and of grandiose delusions involving social status and personal power. Women showed an excess of delusions of fertility and of jealousy, and were more often than men objects rather than subjects in their grandiose delusions. There was an excess of women who reported co-objects of persecution, and who personally knew their persecutors, nearly always men. These differences mirrored aspects of the social environment, especially with regard to sex-role stereotyping. 相似文献

Purpose
Persecutory delusions are a central psychotic experience, at the severe end of a paranoia spectrum in the general population. The aim of the review is to provide an introduction to the understanding of persecutory delusions, highlight key putative causal factors that have the potential to be translated into efficacious treatment, and indicate future research directions.Methods
A narrative literature review was undertaken to highlight the main recent areas of empirical study concerning non-clinical and clinical paranoia.Results
Six main proximal causal factors are identified: a worry thinking style, negative beliefs about the self, interpersonal sensitivity, sleep disturbance, anomalous internal experience, and reasoning biases. Each has plausible mechanistic links to the occurrence of paranoia. These causal factors may be influenced by a number of social circumstances, including adverse events, illicit drug use, and urban environments.Conclusions
There have been numerous replicated empirical findings leading to a significant advance in the understanding of persecutory delusions, now beginning to be translated into cognitive treatments. The first trials specifically focussed on patients who have persecutory delusions in the context of psychotic diagnoses are occurring. Initial evidence of efficacy is very promising. 相似文献7.
A patient who showed Ekbom's syndrome, i.e. delusions of parasitosis, and also lilliputian hallucination is described. She was diagnosed as senile dementia based on the diagnostic criteria of DSM-III-R and cerebral imaging techniques. When she was 74 years, she felt a mowworm-like wriggle in her stomach and their travels all over her body. When she was 78 years, she saw dressed-up dwarfs dance or march on her abdomen. Since the case showed simultaneously delusions of parasitosis and lilliputian hallucinations, it cannot be denied that she has undetected lesions in the brainstem. In this case, the delusions and hallucinations seem to have occurred as a part of psychopathological signs of senile dementia. 相似文献

To illustrate the dilemma in evaluating and treating patients who deny their illness, the authors present the case of a woman with paranoia who denied she was ill and refused medication. They focus specifically on the issue of whether a patient who denies his or her illness is truly legally competent to refuse or consent to treatment. They conclude that the assessment of such competency requires a consideration of the accuracy of the patient's "appreciation of the nature of his or her situation" and that safeguards have to be built into a system for evaluating competency along these lines to prevent abuse. 相似文献

This paper deals with the cultural elements of the delusions of a sample of Egyptian psychiatric patients. After examination of clinical records, interviewing psychiatrists and reviewing literature, the author reaches the conclusion that the content of the patient's delusion varies directly in relation to his social class. For most of the low class men and women, the delusional symptoms, either megalomaniac or persecutory were fantasied in terms of the cultural religious institutions. Middle and upper class patients, however, much more frequently "secularized" their restitutive narcissistic and self esteem delusions in terms of science and class conception of power. 相似文献

OBJECTIVE: The major cognitive theories of persecutory delusion formation and maintenance are critically examined in this article. METHOD: The authors present a comprehensive review of the literature, citing results of relevant functional neuroimaging and neural network studies. RESULTS: People with persecutory delusions selectively attend to threatening information, jump to conclusions on the basis of insufficient information, attribute negative events to external personal causes, and have difficulty in envisaging others' intentions, motivations, or states of mind. Presence of the "reality distortion" cluster of psychotic symptoms correlates with cerebral blood flow in the left lateral prefrontal cortex, ventral striatum, superior temporal gyrus, and parahippocampal region. Social cognitive processing (selective attention to threat, attribution of causation or mental states) in normal subjects involves similar areas. Neural network models of persecutory delusions highlight the importance of disordered neuromodulation in their formation and of disordered neuroplasticity in their maintenance. CONCLUSIONS: Further studies examining the interaction of these cognitive processes, cross-sectionally and longitudinally, at cognitive psychological, neural network, and functional neuroanatomical levels are warranted to establish a comprehensive cognitive neuropsychiatric model of the persecutory delusion. 相似文献

Genital self-amputation and the Klingsor syndrome 总被引:1,自引:0,他引:1
I Schweitzer 《The Australian and New Zealand journal of psychiatry》1990,24(4):566-569
Two psychotic individuals, who performed acts of genital self-amputation, are presented. One of the patients had self-mutilated with the intention of suicide and had also in the past amputated his hand. Psychotic patients with delusions (often religious), sexual conflict associated with guilt, past suicide attempts or other self-destructive behaviour and depression, severe childhood deprivation, and major premorbid personality disorder, are the group at risk for genital self-amputation. It has been proposed that the eponym, the "Klingsor" syndrome, be applied only to acts of genital self-mutation, involving religious delusions. The author suggests that this syndrome should be expanded to include all cases of genital self-mutation resulting from a psychotic illness. 相似文献

Background and Objectives
Insomnia is a putative causal factor for persecutory thinking. Recent epidemiological studies show a strong association of insomnia and paranoia. The clinical implication is that reducing insomnia will reduce paranoid delusions. This study, evaluating for the first time the treatment of insomnia in individuals with persecutory delusions, provides a test of this hypothesis. It was predicted that a brief cognitive behavioural intervention for insomnia (CBT-I) for individuals with persistent persecutory delusions and sleep difficulties would not only reduce the insomnia but that it would also reduce the paranoia.Methods
Fifteen patients with persistent persecutory delusions and insomnia in the context of a psychotic disorder were each individually given a standard-format, four-session CBT-I intervention. Outcome assessments were conducted at pre-treatment, post-treatment and one-month follow-up.Results
There were no missing data. Following the intervention, significant reductions were found in levels of insomnia and the persecutory delusions. The effect sizes were large, and the changes were maintained at the follow-up. At least two-thirds of participants made substantial improvements in insomnia and approximately half showed substantial reductions in the persecutory delusions. There were also reductions in levels of anomalies of experience, anxiety and depression.Limitations
The main limitations are the absence of a control group and unblinded assessments. A more methodologically rigorous evaluation of this intervention is now warranted.Conclusions
These preliminary findings suggest that CBT-I can be used to treat insomnia in individuals with persecutory delusions and that, consistent with the hypothesised causal role, it also lessens the delusions. 相似文献13.

Persecutory delusions are proposed to be a defence against low self-esteem reaching conscious awareness (Bentall, Corcoran, Howard, Blackwood, & Kinderman, 2001). Key predictions of this proposal are that individuals with persecutory delusions will have lower implicit self-esteem and equivalent levels of explicit self-esteem compared to healthy controls. This study aims to test the predictions regarding implicit and explicit self-esteem in people with persecutory delusions. Of 22 people screened for persecutory delusions, 16 were recruited to the study. 20 healthy control participants were recruited. The Implicit Association Test was used to measure implicit self-esteem and the Rosenberg self-esteem scale was used to assess explicit self-esteem. Positive and negative self and other schemas were also assessed using the Brief Core Schema Scales. People with persecutory delusions had positive implicit self-esteem, comparable to that of the control group. Explicit self-esteem was lower for the persecutory delusion group, but was associated with increased depression and anxiety. Negative self and other schemas were higher in the clinical group. The results do not support the contention that persecutory delusions defend against negative self-representations and low self-esteem reaching conscious awareness. Non-defensive cognitive models are discussed as an alternative way of understanding persecutory delusions. 相似文献

The authors interviewed hemodialysis patients, their families, and medical staff and found that some patients preferred dialysis at a medical facility, which allowed them to appear more "normal" before their children. Patients with more social support involved their children in dialysis at home. The author suggests that social support is of primary importance to the outcome of home dialysis and should be considered by physicians in the assessment of patient's suitability for home dialysis. 相似文献

Chronic mental illness results in the patient becoming adhered to a DSM-IV diagnostic label. Over time, this diagnosis can expand and become a "mask" that invisibly covers over the true person of the patient. Most commonly, two things then occur. First, the outside world forgets that the patient is a person and family, friends, staff, and doctors begin to treat the patient according to the superficial aspects of what the mask of the diagnosis connotes, rather than connecting with the person struggling with the illness. Second and, perhaps, more insidious, is that the patient, who has been vulnerable and shattered by his or her experience and battle with the illness, adopts the mask as a kind of invisible protective shield. The task of making contact with the patient behind the mask of the diagnosis is therefore a formidable one for psychoanalysts and therapists and staff who work with seriously ill patients. Treatment must focus on the dual process of interfering with the patient's use of the diagnostic mask while, at the same time, making safe contact with the person of the patient behind the mask. A focus on affect can help achieve these dual goals. By utilizing Semrad's (Semrad and van Buskirk, 1969) method of noticing and asking about "feelings" as conveyed by hallucinations, delusions, or bodily sensations, a reliable relationship can evolve and the clinician can come to have an important "selfobject" (Kohut, 1971) meaning for the patient. By attuning to the patient's "vitality" affects (Stern, 1985), great stability and a new sense of "aliveness" is made possible to help the patient emerge from the deadening effects of the illness and the mask of the diagnosis. 相似文献

Previous research has found that reduced self-reassurance and heightened verbal ‘self-attacking’ of a sadistic and persecutory nature are both associated with greater subclinical paranoia. Whether these processes are also linked to clinical paranoia remains unclear. To investigate this further, we asked 15 people with persecutory delusions, 15 people with depression and 19 non-psychiatric controls to complete several self-report questionnaires assessing their forms and functions of self-attacking. We found that people with persecutory delusions engaged in more self-attacking of a hateful nature and less self-reassurance than non-psychiatric controls, but not people with depression. Participants with persecutory delusions were also less likely than both healthy and depressed participants to report criticising themselves for self-corrective reasons. Hateful self-attacking, reduced self-reassurance and reduced self-corrective self-criticism may be involved in the development or maintenance of persecutory delusions. Limitations, clinical implications and directions for future research are discussed. 相似文献

Paranoia, persecutory delusions and attributional biases 总被引:3,自引:0,他引:3
An influential model of persecutory delusions put forward by Bentall and colleagues hypothesizes that persecutory-deluded patients avoid the activation of negative self-beliefs by making externalising, personalising attributions for negative events. The first study reported here used a new instrument for the measurement of persecutory ideation, the Paranoid, Persecutory and Delusion-Proneness Questionnaire, to investigate whether attributional biases are associated with subclinical persecutory ideation. The second study extended this investigation by re-examining associations between attributional biases and persecutory delusions. Both studies used the Internal, Personal and Situational Attributions Questionnaire to measure attributional style. No evidence was found for a connection between attributional biases and subclinical persecutory ideation. Furthermore, there was no support for an association between persecutory delusions and an externalising bias, and only marginal support for the hypothesized relationship between persecutory delusions and a personalising bias. These results suggest that the putative link between persecutory ideation and attributional biases only manifests (if at all) when persecutory ideation is of delusional intensity, and that it is confined to a personalising bias. 相似文献

Many studies have found that people experiencing persecutory delusions have a marked tendency to use external-personal attributions when establishing the causes of negative events. Although nonclinical populations also tend to attribute negative events to external causes, those causes are typically believed to be universal in nature, rather than personal. The central goal of the present study was to investigate whether individuals with remitted persecutory delusions would display this external-personal bias regarding negative events, in comparison to remitted patients whose delusions were not paranoid in nature and to nonpsychiatric controls. Results indicate that currently paranoid patients were significantly more likely than all other groups, including the remitted paranoid group, to use external-personal attributions in negative events. Interestingly, all patient groups also were found to be significantly more likely than the controls to use internal-personal and internal-universal attributions when explaining negative events. 相似文献

The hypothesis that persecutory delusions function to enhance self-esteem implies that patients will show normal explicit, but low implicit self-esteem. As evidence for this has been inconsistent, our study assessed delusional state, explicit and implicit self-esteem and depression in a large sample (n=139) of schizophrenia patients with acute persecutory delusions (n=28), patients with remitted persecutory delusions (n=31), healthy controls (n=59), and depressed controls (n=21). Patients with delusions and patients with depression both showed decreased levels of explicit, but normal levels of implicit self-esteem when compared to healthy controls. The direct comparison of levels of explicit and implicit self-esteem within each group revealed that healthy controls had higher explicit than implicit self-esteem, while the converse pattern was found for depressed controls. No discrepancy between explicit and implicit self-esteem was found for acute deluded or remitted patients with schizophrenia. Although these findings do not support the hypothesis that delusions serve to enhance self-esteem, they underline the relevance of low self-esteem in patients with persecutory delusions and point to the necessity of enhancing self-esteem in therapy. 相似文献
