As well as updating key chapters that were included in an earlier edition, this volume includes some new topics that are attracting a great deal of interest and point the way to new and promising directions for future research.

The chapters follow five main themes: Current perspectives on the clinical profile of ADHD and its treatment, common co-occurring conditions, neurobiological studies examining brain function and genetics, animal and in vitro studies, and future directions. This combination of topics emphasises the translational relevance and validity of preclinical research so as to enable a better understanding of ADHD and to highlight the promising strategies for developing new treatments.
