Collinge, M. R. "The relationship between childhood abuse and delusions : an investigation based on delusional content." Thesis, University College London (University of London), 2006. http://discovery.ucl.ac.uk/1445390/.

Abstract:
Psychotic illness is associated in the literature with abuse in childhood (Read, van Os, Morrison, & Ross, 2005). This literature is reviewed, focussing on the relationship between childhood abuse and delusions. The review looks to the abuse literature to suggest ways that psychological sequelae of abuse might fit with existing theories of delusions to offer a more comprehensive understanding of their origins. It is argued that current psychological models of delusions do not deal adequately with the impact of childhood abuse. A greater appreciation of this relationship is theoretically import

Abstract:
A research method for investigating delusional beliefs is outlined by adopting the delusional belief that one is dead (the Cotard delusion) as a model delusion. Detailed analyses of published case reports of the Cotard delusion demonstrate that the term 'syndrome' as it is currently applied to the belief that one is dead is not helpful in terms of our understanding of the delusion. Four new case studies of the Cotard delusion suggest that preoccupation with belief may play a role in the formation and maintenance of delusions.

Abstract:
We know little about the formation and maintenance of delusional beliefs. Two main approaches have dominated the scant literature. These seek to account for delusions as primarily disturbances of perception (Maher, 1988) or as differences in reasoning (Garety, 1991). The concern here is with reasoning biases. Garety and Hemsley (1994) have proposed a model in which delusions’ are caused by a "failure to utilise previously acquired information". This leads to people with delusions exhibiting characteristic information processing biases in reasoning (i.e. hastiness and overconfidence). The aim o

Abstract:
Delusions can be reliably identified in clinical populations. However their definition has been a matter of controversy. Attributes that are commonly used to characterise delusions, such as falsity and excessive conviction, do not generally distinguish them from more ordinary beliefs. The convention that considers delusions as forms of belief obscures many of the important points of distinction from more ordinary beliefs. Conceptual review of the concept of bizarre delusions suggests that delusions are distinguishable from other forms of belief by virtue of their individual bizarreness. That

There is a considerable body of research demonstrating that childhood sexual abuse (CSA) is associated with widespread short- and long-term psychopathology, and moreover, is connected with the most severe, chronic and life-threatening consequences of a wide range of psychiatric disorders. More specifically, there is a growing body of evidence reporting that CSA is related to psychotic symptoms and diagnoses of schizophrenia, and some authors have found thematic links between the nature of abuse and the content of psychotic symptoms.

Visual well-formed hallucinations, fluctuations in the level of cognition, and alertness and extrapyramidal signs are core features of dementia with Lewy bodies. Some patients realize that what they are seeing or hearing are just hallucinations and learn to accept them. Others, however experience these hallucinations as quite real and cannot be dissuaded from the firm belief that they are. In fact, efforts to dissuade them often serve only to confirm the often associated paranoid delusions and this may lead to a catastrophic ending. Hence, it is best not to contradict the patient.

In Chapter 1, I examine and criticise standard attempts to answer the question “What is delusion?” In particular, I claim that such attempts are misguided because they misunderstand the kind of term that “delusion” is. In Chapter 2, I look at the nature of explanation in psychology and apply it to delusions. In particular I look at the constraints on a successful explanation of a person’s psychological state in ter

There is no accepted definition of belief and it is likely that the everyday use of the term does not represent a single neuropsychological entity. Nevertheless, cognitive neuropsychiatry is likely to be useful in understanding belief-related phenomena, as it does not necessarily require the focus of study to be a unitary construct. The label 'delusion' is likely to be an umbrella term for a variety of pathologies that lead a person to make an unlikely belief-claim or to have an unlikely belief attributed to them on the basis of their behaviour, in tandem with the person experiencing significa

This thesis attempts to recover the voice of those termed ‘delusional’ and gives reasons why they should have a place in the ‘conversation of humanity’.

I argue that it is the poverty of this picture that leads to the idea that delusions are empty speech acts, incomprehensible, or irrational and incorrigible false beliefs.
