Design outcomes

Primary

MeasureTime frame
Main Objective: The main objective is to assess the changes in DMN connectivity and in fMRI BOLD response in patients with ADHD compared to healthy controls during a 2 week treatment with atomoxetine. Atomoxetine is proven to normalize the brain activity of patients with ADHD and improves their cognitive performance. One of the main aims of our study is to improve our knowledge about ADHD and its underlying neurophysiological mechanisms of functioning. Furthermore, we are planning to examine the meaning of normalized DMN activity and reward processing of patients with ADHD for an improved cognitive performance. Moreover, we are confident that the results of our study will enable us to make new interferences for future psychotherapeutic treatment. ;Secondary Objective: not applicable ;Primary end point(s): To examine the influence of atomoxetine related changes in brain activity on cognitive performance in patients with ADHD compared to controls. ;Timepoint(s) of evaluation of this end point: end of the second fMRI session
