This is an updated edition incorporating the scientific underpinnings of newer theories of neurodevelopment, developmental psychopathology and neurobiology informing the childhood psychiatric disorders and their management, introduces the latest classification systems like ICD 11 and DSM 5, newer treatment approaches, and some contemporary clinical issues, i.e. psychiatric disorders of infancy, substance abuse and child sexual abuse. The book provides an insightful account of clinical approach and theoretical substructure of the process of assessment and management of psychiatric disorders seen in children and adolescents. It gives the rationale for the scheme, the system to be followed and step-by-step guidance into comprehensive evaluation of children and adolescents seen in psychiatric clinics. The book is written in a simple and readable style and derives value from over five decades of experience and vast expertise of the author and clinical insights obtained from the treatment of thousands of children and their families. An essential textbook for all postgraduate (MD) students of psychiatry and pediatrics, postdoctoral (DM and PDF) students of child and adolescent psychiatry and clinical child psychologists, this book also has tremendous value for practicing psychiatrists and pediatricians who are routinely called upon to treat child and adolescent psychiatric disorders. In addition to clinical guidance for assessment, the book also gives practical advice on how to plan and initiate treatment. A brief account of psychopharmacology for child and adolescent psychiatric disorders with detailed guidelines for its usage and monitoring would help the clinician undertake drug treatment with greater clarity and confidence. Non-pharmacological methods which constitute the most essential forms of treatment recommended for all children with psychiatric disorders have been introduced and briefly described in a simplified manner for most clinicians to use with ease. Inclusion of diagnostic and treatment algorithms, scales commonly used for measurement of general or specific psychopathologies, details of psychometric assessments, and inclusion of some well-known Indian scales/instruments makes the book a useful resource for most researchers and academicians
