About the book
Psychosis is not only a type of inevitable failure of brain functions, but also a valuable phenomenon through which the structure of human psychic system can be understood. On psychopathology of psychosis, phenomenological approach introduced by Karl Jaspers has been generally used for description and characterization of psychosis, although the methodology has occasionally been criticized. On diagnosis of psychosis, the question has been raised recurrently, as to which of the symptoms, auditory hallucination, delusion, thought disorder or personality change should be thought as essential for psychosis. On classification of psychosis, operationalism on which DSM is based is to be critically reconsidered and other possibilities like the unitary psychosis theory should be revisited. In regard to pathophysiology of psychosis, there are various promising approaches of research at present, for example, the neural mechanism of self-disorder, theory of dual consciousness, aberrant salience hypothesis, and autoimmunity hypothesis. Social and cultural aspects of psychosis should also be addressed. The concept of psychosis should be analyzed as a social construction, and the fundamental question would be posed on when and why psychosis has appeared in the history of human kind.
This book intends to show the reader the broad, abundant and intriguing expanse of problems on psychosis.
