As people across all nations around the world are beginning to live longer, the World Health Organization estimates the number of older adults will double to 1.5 billion by 2050. This presents visible increases in older adult mental health issues, and it is therefore vital that we understand the cross-cultural impact of social determinants of health in psychiatric illness and care in aging adults.As part of the Oxford Cultural Psychiatry series, Mental Health in Older People Across Cultures provides a detailed overview of the diverse factors, including socioeconomic and systemic factors within and across countries that impact the process of ageing, mental health and illnesses of older adults, and their care. This unique resource provides a necessary clinical understanding of factors on ageing, and the varied roles that families and caregivers have on the ageing process, with an emphasis on highlighting similarities and differences across cultures. The second half of the book then focuses on specific disorders in older adults across the globe affected by these factors, the nuances impacting diagnosis and treatment of these disorders, as well as research and development of healthcare policy.Written by experts in the field from across the world, this comprehensive book will be of great interest to a diversity of readers, from psychiatrists to trainees, general practitioners to social workers, and many other mental health providers. From epidemiology to economics and substance use disorders, and from East Asia, to Africa, and the Americas, this valuable addition to the field of mental health in older adults provides a world of fascinating insight.
