With an increasing global ageing population, the psychiatry of old age has become increasingly important. This revised second edition remains a succinct manual on the practice of psychiatry of old age, providing an up-to-date summary of existing knowledge, best practice and future challenges for the specialty, from a global perspective. Written by four leading clinicians, teachers and researchers, the book offers a much-needed international focus and is designed for use in a wide variety of countries and settings. Chapters are presented in a clear and practical way, enhanced by current and comprehensive further reading sections as well as tables and diagrams for quick assimilation and reference. The new edition is updated to incorporate new developments in assessment, investigation, classification, treatment and care since the publication of the first edition, including the ICD-11 and DSM-5. Essential reading for practising psychiatrists and geriatricians, as well as trainees, nurses and medical students.
