Intervention type: DIAGNOSTIC_TEST
Intervention: Magnetic Resonance Imaging
Description: The MRI sequence protocol includes resting state fMRI before and after the participants do an established 20 min long reaction time measurement paradigm (E-prime). During the paradigm a pseudo-continious arterial spin labeling sequence (pCASL) is acquired for continuous measurement of brain perfusion. Following the functional sequences the imaging protocol also includes a high resolution 3D T1weighted sequence Magnetization Prepared Rapid Gradient Echo (MPRAGE) for brain structure, a high resolution 3D T2-weighted sequence Fluid-Attenuated Inversion Recovery (FLAIR) for pathology and a 3D susceptibility weighted image (SWI) for microvascular abnormalities.

Intervention type: DIAGNOSTIC_TEST
Intervention: Immunological biomarkers
Description: Venous blood samples (10-20 ml) are taken from the elbow crease. They are drawn in the morning, and the participants are asked to fast for 12 hours prior to sampling. They are also asked to avoid physical activity prior to blood sampling. The samples are drawn into citrated tubes.
