The Aging Brain: Proven Steps to Prevent Dementia and Sharpen Your Mind talks about ways to fight against dementia. The book discusses a wide range of topics and how they relate to aging, such as epigenetics, diet and obesity, tobacco and alcohol, exercise, sleep, rest, and mental stress. One of the most helpful sections was Chapter 16, which talks about risk factors for dementia and how to reduce the risk.

The Aging Brain is a very relevant book, since according to the World Health Organization, around 50 million people have dementia, and there are nearly 10 million new cases each year. Though dementia is a mysterious disease – and many people with healthy lifestyles still get it – the healthy lifestyle modeled in this book not only decreases dementia risk factors, but also decreases risk factors of other diseases. I like how the book includes action plans for combating dementia that mention specific things people can do to prevent dementia. The book not only explores health factors related to dementia, but also examines how mental and spiritual well-being may play a role in warding off dementia.
