How to Prevent Dementia begins with the principle that the more we know about dementia, the easier it is to prevent or delay it. A better foundation of knowledge also helps people to understand and interact thoughtfully with loved ones living with the condition.

The book shows that dementias exist on a spectrum, starting with perfectly normal performance and ending at the extremes of mental dysfunction. Dr Restak also provides practical advice on how to reduce your risk of developing the condition, and sheds light on both the positive and more challenging consequences of pioneering new dementia medications that will soon be available.

At the end of the book, the reader will understand what practical steps can be taken each day to lessen the odds of dementia, and how to take advantage of new medications, all while gaining a better understanding of thinking, and what it is like to have it falter.
