This book offers a comprehensive and scientifically grounded exploration of major clinical disorders, dominant models, rehabilitation approaches, and ethical considerations shaping the landscape of mental health and mental illness among older adults. The authors provide unique insights into fundamental issues in geriatric mental health by drawing on extensive clinical practice, research, and policy expertise. As the importance of geriatric mental health continues to grow, this book addresses the timely resource that bridges theory, practice and policy. With its clear organisation and accessible presentation, it will be an invaluable resource for newcomers in the field and those seeking to deepen their understanding of geriatric mental health rehabilitation. By offering a broad perspective on various interventions and developments, this book equips readers with the knowledge and tools necessary to navigate the complexities of geriatric mental health care. Designed to serve as both a reference and a guide, this volume will be helpful to students, researchers, and educators in occupational therapy, physical therapy, clinical psychology, medical sciences, psychiatry, public health, sociology, and social work. It is an equally valuable resource for nurses, paramedics, NGOs working in the health care, and policymakers committed to advancing mental health services for ageing populations.
