Dear colleagues,

In the two years since we met in Lisbon, the science and practice of ADHD has continued to develop at a rapid pace. From new findings in genetics and imaging to novel therapeutics, we have much to share at the 8th World Congress of ADHD, which will take place in Prague from 6 – 9 May 2021. Hope you will join us in Prague to learn from world class researchers and clinicians and to share and exchange experiences with your colleagues from around the world.
