Brain Function After Cardiac Arrest (Measured With FMRI and Cognitive Tests)

The aim of this longitudinal study is to determine whether brain function is affected after a cardiac arrest. The primary question is whether cognitive function is affected after cardiac arrest and whether it changes over time (during the first year after the event), compared with a healthy control group. Brain function during cognitive tasks and emotion processing will also be studied using functional MRI (fMRI). Another aim is to study whether clinical outcomes such as PTSD, anxiety and depression can be correlated with cognitive function and whether health- related quality of life is affected after a cardiac arrest. The results from the cardiac arrest patient group will be compared with a healthy control group.
