This book reviews our knowledge of the incoherent speech which can
present as a symptom of schizophrenia. This is one of the most
researched symptoms in the disorder. The content covers clinical
presentation, differential diagnosis and the theories proposed to
account for the symptom in these 'thought disordered' patients,
ranging from the psychoanalytic to there being a form of aphasia
involved. The book is unique in its ability to apply linguistic and
neuropsychological approaches to the understanding of this condition,
and is the first book to cover comprehensively the range of clinical
studies that followed the introduction of Andreasen's rating scale
for what was then called thought, language and communication
disorder. This book is essential reading for all those working in the
field of schizophrenia and also for those interested in language and
disorders of speech.
