This book provides a bi-national portrait of dementia in the rapidly aging Mexican-origin population in Mexico and the United States. It provides a comprehensive overview of critical conceptual and methodological issues in the study of cognitive aging and related mental and physical conditions. The book examines the sources of vulnerability and their consequences for Mexican-origin and for “aging in place�. By providing a combination of new knowledge, empirical evidence, and fresh approaches of dementia support in later life, this book will contribute to moving the field of Mexican-origin aging and health forward. By focusing on the serious challenges in old-age support for older people with dementia and neurocognitive disorders in two different contexts, this book will deepen academics, researchers, students and young investigators understanding of what is necessary to achieve optional care.
