This new edition introduces two new co-editors, Robert Stewart, Professor of Psychiatric Epidemiology & Clinical Informatics at King’s College London (and a Co-Editor of Practical Psychiatric Epidemiology), and John-Paul Taylor, Professor of Translational Dementia Research at Newcastle University.Part of the authoritative Oxford Textbooks in Psychiatry series, this comprehensive resource is an essential reference for old age psychiatrists, geriatricians, and other clinicians who are interested in the mental health care of older people.
