The human brain is a magnificent structure that can function to maximize our ability to lead a very long and satisfying life. Brain health and optimal engagement in older adulthood focuses on the brain as the single most important human organ as we adapt to the many challenges of the aging process. This book links brain health and family, friendship and professional relationships in older adulthood with maintaining a high quality of life well beyond the seventh and eighth decade of life. Pragmatic suggestions based upon the most recent scientific evidence are provided to help each of us maintain brain health. The importance of maintaining a balanced interactive network into older adulthood is not only dependent upon brain health but is shown to be a direct result of brain health. The three authors of this book from three distinct scientific backgrounds: life span development; clinical neuropsychology; and public health, blend their diverse perspectives into a unique understanding of successful aging that offers each reader insight in how to maximize their potential to lead a high quality of life throughout the entirety of the life span.
