Professor Jan Haavik will reveal biological mechanisms that can cause ADHD symptoms.

In 2004, Haavik started the extensive research project "ADHD: from clinical characterization to molecular mechanisms" that will study adults with ADHD. The project has great national and international impact and has already been very important for practical diagnostics and treatment of patients with ADHD in Norway.

He is a member of the KG Jebsen Center for Neuropsychiatric Disorders, and partner in the EU project CoCA. CoCA stands for "Comorbid Conditions of Attention Deficit / Hyperactivity Disorder" and will study cohabitation of ADHD from multiple angles.

Haavik received the Helse Vest research award in 2016 and became a member of the Norwegian Academy of Sciences in 2018.

Jan Haavik completed his medical education at the University of Bergen in 1983. As a student, he started his research career in biochemistry, biophysics and molecular biology. He conducted a tour of Bergen and the municipalities of Agder, graduated from the University of Bergen in 1989, and was employed as a professor, 34, at the present Institute of Biomedicine in 1993. In the period 1986-2014 he had nine shorter and longer research stays at outstanding research institutions in Sweden, Scotland, Germany, France, the United States and the Netherlands. From 2002 he has had a 20% position as a general practitioner in psychiatry, first at Øyane DPS and later at Kronstad DPS, both affiliated with Helse Bergen.
