Originally published in 1977, this book was written in response to demands for a textbook of psychiatry which was neither too theoretical, nor so simple that it was inaccurate. It was addressed primarily to pupil nurses in hospitals for the mentally ill, and to student nurses in their first months of training. Its style and content ensured that it could be read with profit by all others whose work brought them into close contact with the mentally ill. The early chapters provide a history of care and treatment, an introduction to psychological development and the unconscious mind, and an explanation of mental disorder and its causes. Specific mental disorders are discussed together with an outline of their treatments, and the general management of the patient is described wherever appropriate. Case illustrations are given as specific examples of various mental conditions. The final chapters cover modern psychological and physical treatments, the aims and means of rehabilitation, and the resources available for the care of the patient in the community. Today it can be read in its historical context. This book is a re-issue originally published in 1977. The language used is a reflection of its era and no offence is meant by the Publishers to any reader by this re-publication.
