Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Phenotyping will occur according to the procedures of the previous measurement and includes questionnaires and a semi-structured interview to determine the presence and severity of ADHD and comorbid disorders. These will be the primary outcome measures in most analyses. The main predictors are: 1) Various MRI measures. The MRI scan consists of a 90-minute session (structural MRI, resting state, DTI, and fMRI (stop-task, reward-task, and a spatial working memory task)). Furthermore, an MRS session is included to measure levels of glutamate in the prefrontal cortex. 2) Outside the scanner, various additional cognitive tasks are administered (cognitive flexibility, verbal and visuo-spatial working memory, time reproduction, motor timing, motor control, intelligence, and positive and negative reward). 3) A blood sample will be acquired via a venipuncture to investigate biomarkers, gene expression and epigenetics. | — |
