This unit of study is designed for psychiatrists in training, doctors working in paediatrics and general practice and other health professionals working with children and adolescents with mental health and with their families and carers. The unit will draw on the clinical and research experience of child and adolescent psychiatrists, including those with subspecialty interest (addiction, forensic, consultation-liaison and perinatal included) from a group of professionals who work with children and young people (including paediatricians, psychologists, nurse practitioners and those working in health advocacy). This unit provides an overview of child development and mental health from conception through adolescence, looking at key genetic and environmental factors that contribute to clinical disorder. Major psychopathologies such as mood and anxiety disorders, psychosis and neurodevelopmental disorders will be examined. Particular attention will be given to presentation across contexts, from community care to specialist inpatient and consultation settings. A key objective of this unit is to provide students with the fundamental knowledge required to assess and formulate child, adolescent and youth psychopathology. Students will be provided with an opportunity to develop skills in the assessment of young people and their families and carers and will learn about management options for common psychiatric presentations including psychological and pharmacological treatments as well as approaches to working with families, carers and wider systems including multidisciplinary teams, education and welfare sectors.
