Thank you Michael for the really interesting article. I have completed recently my PhD on ADHD drug holidays and published October last year (2014) a Review on the practice of drug holidays from ADHD medication in children and adolescents and found out (confirming your views) that they can be a useful multiple tool: identify the continuing need for ADHD medication and the ability of the CHILD to cope without the medication, manage the physical and psychological side-effects of medication, manage or avoid development of drug tolerance (the need to increase the dose continually to achieve the same effectiveness), and prevent drug-induced growth retardation. if interested please check my article: http://www.ncbi.nlm.nih.gov/pubmed/25253684 interestingly, although drug holidays could be helpful and carry no harm with its practice, many parents and practitioners seem to be not in favour of trying to stop the medication for a variety of reasons. Drugging children continues despite the fact that many of them experience really unpleasant and serious side-effects. Sadly improvement at school performance and behaviour is the main driver for keep medicating children.
