Written to encourage defensive action, Levine's book is meant both as a guide and a reference to understanding and preventing dementia. It is intended for lay people interested in learning about dementia and the measures that can be taken to repel its onslaught, as well as for caregivers and family members of impaired patients.Defying Dementia is presented in two sections. First, Levine explains the various types of dementia, its increasing incidence and current treatments, and the treatments being tested and on the horizon. The role of physiology and fresh insights from the field of genetics are included. The second section focuses on methods that can be incorporated into a healthy lifestyle to help avoid dementia.How do we motivate individuals to take action or change behavior in response to a possible threat that has not yet materialized? When the threat is dementia, argues longtime neurologist Robert Levine, it is an issue of considerable importance. The earlier the campaign is initiated to defeat this lurking foe, the greater the chances the combatant will emerge victorious.Written to encourage such defensive action, Levine's book is meant both as a guide and a reference to understanding and preventing dementia.

Vignettes illustrate how dementia in its many forms can be recognized as it emerges.With proper actions on our part, we can achieve mastery, Levine writes. The transformation may not be easy, but recognizing the scourge that dementia is, and the way it devours the humanity of its victims, may inspire us to move ahead. Preparation is the key word; building solid defenses over time. And while any moment is worthwhile to begin this task, the earlier the better.
