In the tradition of EUNETHYDIS meetings, our primary focus will be on ADHD and associated conditions. The ultimate objective of our work is always focused on improving the lives of those with ADHD and of those around them. In order to do this we need to conduct basic scientific work to help us better understand the nature of ADHD and its causes in order to stimulate therapeutic innovation and hopefully in the longer term develop ways to base diagnosis and treatment on a strong theoretical foundation. From a clinical perspective we need to not only develop our understanding of what works and for whom but also to roll this evidence out into day to day clinical practice.
