Intellectual Disability (ID) describes a lifelong condition of heterogeneous aetiology, associated with the impairment of intellectual functioning (IQ < 70), significant impairment of adaptive skills, and onset before the age of 18 years. People with ID experience significant physical and mental health problems like associated sensory/motor impairments and epilepsy, some of which are contributed to by underlying primary causes. Psychiatric problems are also three times more common in people with ID in comparison to the general population.

The psychiatry of ID is a core part of training to be a psychiatrist yet there are limited resources on this topic aimed at both trainees and practising clinicians alike. Oxford Textbook of the Psychiatry of Intellectual Disability bridges this gap by providing up-to-date evidence-based content on the assessment, diagnosis, and management of psychiatry in people with ID.

Featuring 28 chapters written by international experts in the field, the Oxford Textbook of the Psychiatry of Intellectual Disability presents fresh global insight and coverage of the subject. Chapters cover key topics from the developmental aspects of ID, mental disorders in childhood, and behaviour phenotypes, through to physical health, dementia and other disorders associated with ageing.

Each chapter provides trustworthy evidence and a wealth of practical advice for clinical situations, including case studies in community and hospital settings, and multiple choice questions for self-evaluation and consolidation of knowledge.
