There is a curious parallel between the philosophy of science and psychiatric theory. The so-called demarcation question, which has exercised philosophers of science over the last decades, posed the problem of distinguishing science proper from non-science - in par ticular, from metaphysics, from pseudo-science, from the non rational or irrational, or from the untestable or the empirically meaningless. In psychiatric theory, the demarcation question appears as a problem of distinguishing the sane from the insane, the well from the mentally ill. The parallelism is interesting when the criteria for what fails to be scientific are seen to be congruent with the criteria which define those psychoses which are marked by cognitive failure. In this book Dr Yehuda Fried and Professor Joseph Agassi - a practicing psychiatrist and a philosopher of science, respectivel- focus on an extreme case of psychosis - paranoia - as an essentially intellectual disorder: that is, as one in which there is a systematic and chronic delusion which is sustained by logical means. They write: "Paranoia is an extreme case by the very fact that paranoia is by definition a quirk of the intellectual apparatus, a logical delusion. " (p. 2.

Delusional disorder, once termed paranoia, was an important diagnosis in the late nineteenth and early twentieth centuries, and only in 1987 was it reintroduced into modern psychiatric diagnosis after being subsumed with schizophrenia. This book provides a comprehensive review of delusional disorder for psychiatrists and other clinicians. Beginning with the emergence of the concept of delusional disorder, the book goes on to detail its manifold presentations, differential diagnosis and treatment. Many instructive case histories are provided, illustrating manifestations of the various subtypes of delusional disorder, and related conditions in the paranoid spectrum. This is the most wide-ranging and authoritative text on the subject to have appeared for many years, and the first to suggest, based on the author's extensive experience, that the category of delusional disorder should contain not one but several conditions. It also emphasizes that, contrary to traditional belief, delusional disorder is a treatable illness.

An international team of leading researchers and clinicians provides the first comprehensive, epidemiological overview of this multi-faceted and still-perplexing disorder. Controversial issues such as the validity of discrete or dimensional classifications of schizophrenia and the continuum between psychosis and 'normality' are explored in depth. Separate chapters are devoted to topics of particular relevance to schizophrenia such as suicide, violence and substance abuse. Finally, new prospects for treatment and prevention are considered.

Do you often suspect the worst of others? Mild to moderate paranoia, or mistrust of other people, is on the increase, and although it may feel justifiable at the time, unfounded suspicions of this kind can make life a misery. Research says between 20 and 30 per cent of people in the UK frequently have suspicious or paranoid thoughts. This is the first self-help guide to coping with what can be a debilitating condition.
