"Provides an excellent update to the general psychiatrist and many others, highlighting how far the field of intellectual disabilities has come and how rapidly it is now moving into the future. ...The nature of the book, divided into discrete chapters addressing specific topics, allows the reader to pick and choose topics to their own specific needs. This makes the text an ideal starting point for the clinician who wants to update their knowledge and consider what further reading would be appropriate for them." - Journal of Applied Research in Intellectual Disabilities"This book is worth reading and in most areas is a valuable reference guide." - The British Journal of Psychiatry (BJPsych)
