Professor Kerryn Phelps AM, Australia's most trusted GP, reveals how to keep our most important organ at its best throughout our lives. In her standout new book, Professor Phelps addresses what we all fear: losing mental function as we age. While ageing physically is inevitable, ageing mentally is not. In this accessible book, Professor Phelps lays out the basics of the brain and the simple, everyday practices for keeping our brains younger for longer. Through the ongoing science of neuroplasticity, we know that our brains are continually capable of rewiring and relearning. Professor Phelps applies this knowledge to an array of simple, sustainable lifestyle habits, showing how anyone, whether starting at 40 or 80, can age gracefully and keep mentally sharp. How to Keep Your Brain Young details the fundamentals of a healthy brain, from diet and exercise to gut microbiome and mindfulness techniques, and shows us how to feel sharper, kick out the brain fog and retain mental acuity in later life. Drawing on years of clinical experience and the latest research, How to Keep Your Brain Young is the ultimate guide for happy, healthy grey matter.
