Here is a concise, comprehensive review of mental health problems by the director of the psychiatric clinic for children at the University of Minnesota. In his forward-looking textbook for nurses Dr. Clarke discusses the signs and symptoms of mental disorders in a simple, direct fashion. He stresses the importance of early recognition of mental deviations and charges the community nurse with the responsibility of recognizing the problem and guiding the patient to the proper channels for diagnosis and treatment. A selected group of personal histories of children and adults gives a cross section of the problems the community nurse may encounter, offering a rich filed of discovery for beginners and a valuable supplement to the clinical experience of nurses already engaged in field work.
