Bad Boys, Bad Men examines antisocial personality disorder, or ASP, the mysterious mental condition that underlies a lifelong penchant for bad behavior. Donald W. Black, MD, draws on case studies, scientific data, and current events to explore antisocial behavior in men and to chart the history, nature, and treatment of a misunderstood disorder affecting nearly seven million Americans. Citing new evidence from genetics and neuroscience, Black argues that this condition is tied to biological causes, and that some people are simply born bad. Examining compelling cases that read like medical detective stories, he separates the lies these men tell from the facts their lives reveal. His book not only describes the warning signs that predict which troubled children are more likely to become dangerous adults, but also details the progress toward treatment for ASP.
