Spanning the fields of paediatric medicine, paediatric neurology, and child and adolescent psychiatry, this resource covers all aspects of paediatric neuropsychiatry. The text provides child and adolescent psychiatrists, neurologists, paediatricians and other clinicians with coverage of the latest developments in research, theory, assessment and diagnosis, treatment and other aspects of clinical practice. This text offers an at-a-glance reference to all fundamental topics in paediatric neuropsychiatry and contains a thorough, exhaustive and current literature review. The "Textbook" is organized into five sections. Section 1 discusses the specialty of paediatric neuropsychiatry, normal and abnormal brain development, cerebral connectivity and normal growth and physical development. It includes an integrative model linking developmental brain biology with behaviour. Section 2 discusses normal behavioural and personality development; bedside, neuropsychological and psychoeducational assessment of the paediatric patient; and the role of advanced brain-imaging technologies in the evaluation of children and adolescents. This section defines the acceptable limits of normal brain development. Sections 3 and 4 provide the clinical core of the "Textbook" and focus on the neuropsychiatric aspects of psychiatric and neurological disorders in children and adolescents. These sections highlight how the developing nervous system influences the pathophysiology, neuropsychiatric manifestations, clinical course, treatment, and prognosis of psychiatric and neurological illness. Section 5 examines the psychopharmacology, electroconvulsive therapy, genetic interventions, psychosocial and family therapies, educational interventions, and residential facilities. The section also includes a chapter on the special legal considerations that impact the provision of care for these patients.
