If you are a reader of neuroscience and, in particular, brain biology, you will likely encounter familiar topics in Drew Ramsey’s wonderfully readable book, Healing the Modern Brain: Nine Tenets to Build Mental Fitness and Revitalize Your Mind. Ramsey’s crystal-clear prose in explaining complex neuroscientific concepts will not leave you glaze-eyed and struggling. On the contrary, readers are in safe hands as he takes them through what the phenomenal human brain does, and positions them to develop a plan for building mental fitness.
Before getting to “the nine tenets,” Ramsey briefly describes obstacles to mental fitness, which include, not surprisingly: devices, vices and substances, pollutants and toxins, ultra-processed foods, and chronic stress. Each of these obstacles have the potential to affect brain health and mental fitness. He also debunks the notion that humans are “born with a set of about one hundred billion brain cells and that was that.” However, says Ramsey, the brain has the ability “to change and grow as we age.”
The flip side of the obstacles coin include “the big three brain protectants: increased neuroplasticity, decreased inflammation, and a more diverse microbiome,” all of which facilitate the cultivation of mental fitness and a more resilient brain. Neuroplasticity, for example, is conducive to “brain growth.” A diverse, healthy microbiome relates to (as ugly as it may sound) gut-dwelling bacteria. As well as bad bugs, there are good bugs which “act as chemical messengers, providing the brain with key updates about the world around us.” Lastly, the blessing-and-curse nature of inflammation is well-known. The immune system relies on “good inflammation” to protect the body from unwanted viral and bacterial invaders, and also to repair cells damaged by injury. “Bad inflammation,” especially when it reaches chronic levels and is found in the brain, “can lead to depressive and anxiety symptoms, as well as sleep problems.”
Having established this much context, Ramsey takes a deep dive into each of the nine tenets, namely, Self-awareness, Nutrition, Movement, Sleep, Connection, Engagement, Grounding, Unburdening, and Purpose. Most of these single-word descriptors have self-evident explanations (although perhaps Grounding and Unburdening could benefit from better labeling!).
Nevertheless, author Ramsey (board-certified psychiatrist and leading voice in nutritional psychiatry and integrative mental health) does an excellent job of packaging the theory and practice of the nine tenets, bringing readers to a comfortable sense of something very do-able in striving for mental fitness and building brain resilience. “Pick a tenet, any tenet,” says Ramsey. “Decide to make a change. See it through. You’ll be surprised where it may take you—and the kind of resilience that will follow.”
