When the first edition of Pediatric Psychopharmacology published in 2002, it filled a void in child and adolescent psychiatry and quickly establishing itself as the definitive text-reference in pediatric psychopharmacology. While numerous short, clinically focused paperbacks have been published since then, no competitors with the scholarly breadth, depth, and luster of this volume have emerged. In the second edition, Christopher Kratochvil, MD, a highly respected expert in pediatric psychopharmacology, joins the outstanding editorial team led by Dr. Martin and Dr. Scahill. In the new edition, the editors streamline the flow of information to reflect the growth in scientific data since the first edition appeared. The overall structure of the book remains the same, with major sections on underlying biology; somatic interventions; assessment and treatment; and special considerations.
