This volume in the book series Healthy Ageing and Longevity focuses on the interaction and co-dependence of the brain and mental health during ageing. A wide-range of topics discussed here include conceptual and historical understanding, descriptive analyses, and evidence-based interventions for the maintenance, enhancement and recovery of the brain and mental health, especially in old age. The emphasis is on the effective biological and psycho-social lifestyle factors, and complementary medicine and traditional cultural practices that could be health beneficial. Potential readership includes the early stage- and experienced researchers in biogerontology and cognitive sciences, and college/university teachers, medical practitioners, health care personnel, and public educationists. .
