Exposing a developing embryo or fetus to alcohol can produce life long brain damage with neurological, cognitive and behavioural consequences. The implications of fetal alcohol spectrum disorder for the affected individual and the family are devastating. The social and economic burden to society is enormous with formidable expenditures in health care, mental health care, education, social services and possibly correctional services. Prevention has been a goal since the condition was medically described and defined forty years ago, but has remained elusive but feasible. This book reviews the evidence for effective strategies. It lays out what needs to be done. The book should be of great value to policy makers, clinicians, researchers and others advocating for action against this condition that is reducing the potential of our society and sapping its resources.
