Written for the professional and layperson alike, this book looks at mental health, a growing concern amongst the rapidly changing and ever-faster pace of modern society. Each section marked with a colored flag represents a particular mental state or area of the normal mood system, depression, anxiety, addiction and suicide. The author deftly explains the physiology of mental health and helps open a new understanding for sufferers and their families. There is a technical section, and extra appendices at the end of the book including information on self-help groups, and a list of commonly used medicines.
