Traditionally, service provision for neurodevelopmental disorders such as attention-deficit hyperactivity disorder, intellectual disability and autism – where this has been available – has focused on the needs of children, but there is now increased understanding of neurodevelopmental disorders as lifelong conditions, often with an ongoing need for health and social care provision. Medical and allied professionals frequently report limited education in neurodevelopmental disorders both during their training and post-qualification. This article gives an overview of theoretical and practical considerations for training of psychiatrists and allied healthcare professionals in relation to neurodevelopmental disorders. Key UK policy drivers and capability frameworks pertaining to this training are discussed. The Royal College of Psychiatrists’ 2022 revised curricula for medical trainees in psychiatry are examined in relation to neurodevelopmental disorders and ongoing CPD requirements in this area for career psychiatrists are considered. A brief overview of multidisciplinary training in neurodevelopmental disorders and the role of the psychiatrist in this is discussed. An international perspective on training in this area is touched on and current challenges in low- and middle-income countries are outlined. Last, the future direction of training in neurodevelopmental disorders is considered.
