Bailly's review describes the author's perspectives on the ‘intense controversies' surrounding attention-deficit hyperactivity disorder (ADHD) and its treatment with stimulant medications. Drawing on a range of literature sources, including the UK press, pharmaceutical industry websites and peer-reviewed scientific papers, he questions the validity of ADHD as a concept and disorder, the accuracy and reliability of diagnosis, the use of stimulant medications and the impact of advertising by the pharmaceutical industry. There are, however, additional sources and alternative interpretations.
