Brief Summary
The overall aim is to examine the impact of trauma and critical illness on the brain, peripheral immune system and cognition. This is a prospective study where a study group exposed to trauma and intensive care will be be examined with consecutive PET imaging, EEG, biomarkers and cognitive testing within 3 weeks of the trauma, after 3 months and finally after 12 months. The study group will consist of twenty trauma patients treated in the intensive care unit.

Outcome Measures
Primary Outcomes (2)
Neuroinflammation
The trajectory of neuroinflammation as measured by repeated PET-examinations. More specifically, the probe targeting the translocator protein indicates microglia-activation as a sign of inflammatory activation. The change in binding capacity of the probe will be measured, generating a difference in signal in the regions of interest.
3 weeks-12 months post trauma
Cognitive dysfunction
Cognitive function will be evaluated with Cambridge Neuropsychological Automated Battery (CANTAB) with five different tests at three timepoints. A z-score will be calcualted for each test and then aggregated into a total z-score for the entire test.
3 weeks-12 months post trauma
Study Arms (1)
Trauma patients
Trauma patients 20-60 years of age
Interventions
Patients will be tested with PET-examination at 3 weeks, 3 months and 1 year after the trauma
