Central Processing of Odour Stimuli in Patients With Functional Somatic Disorder or MCS Compared to Healthy Controls

The aim of this study is to establish biological models of functional somatic disorders using MRI scans of the brain. A well-known MRI method that has shown neurobiological changes in persons with depression and Alzheimer will be used. The results will be compared with various paraclinical parameters, including the sniffing test, pain thresholds, heart rate variability (HRV) and cognitive function. The objective is to identify if biological markers of functional disorders can potentially be used for diagnosing and testing and for monitoring treatment.
