Approximately 2% of the population meets criteria for intellectual disability (ID), and these individuals will be encountered in virtually every clinical setting. There is a 3–6 times increased rate of psychiatric and behavior problems in individuals with ID compared to the general population. Progress has been made for the provision of high-quality medical and mental health treatment of individuals with co-occurring intellectual disability and mental illness. There remains a lack of universal training among most disciplines in this area, and stigmatization of both conditions continues to varying degrees. Current assessment and diagnostic classifications are available, including adapted criterion sets suitable for individuals with intellectual disability.
