One of the most striking developments within the field of paediatrics in the last decade has been the interest in the hyperactive or overactive child. Major differences have been noted in the frequency of the diagnosis between North America and Europe, but there has been a great lack of any pertinent research data. This volume from the famed Maudsley team discusses overactivity/hyperactivity and attention deficit, and considers how much overactivity in childhood can be assigned a pathologic basis and how much represents normal variation. When the syndrome has been redefined, the authors move on and consider how it can be treated. This should be a useful volume for all who work with children who have difficulties in school.
