Brief Summary

Major Depressive Disorder (MDD) is one of the most severe and frequently occurring brain disorders worldwide. It has been linked to serotonergic dysfunction, sexual dysfunction, vulnerability to stress and neuro-inflammation. However, at the same time the etiological understanding is limited. Most antidepressants act on the serotonin (5- HT) system, yet between 30-50 % of patients with MDD does not respond successfully to 5-HT acting drugs. Recent experimental models from our group suggest that cerebral 5-HT levels in vivo can be indexed through molecular brain imaging of the 5-HT 4 receptor (5-HT4R) with a novel Positron Emission Tomography (PET) ligand (11C-SB207145). Also, our human studies have confirmed that cerebral synaptic 5-HT is inversely related to 5-HT4R binding and this technique thus can be used to investigate the role of 5-HT tone in the brain in MDD with differential responses to standard antidepressant treatment. By using multimodal neuroimaging technology, we aim to determine the status of the 5-HT system prior to and after either successful or failed neuropharmacological intervention in a non-randomized longitudinal open clinical trial. 100 untreated patients with moderate to severe MDD will be included. Data collection from various neurobiological domains (i.e, 5-HT4R PET imaging, Magnetic Resonance Imaging (MRI), functional MRI (fMRI), electroencephalogram (EEG), psychometrics, neuropsychological tests, and peripheral biomarkers) will be conducted before, during and after 12 weeks of antidepressant treatment. The objective is to identify predictors of pharmacological antidepressant treatment response in depressed individuals before and after 8 weeks of antidepressant treatment.
