5. Study Description

Brief Summary
The presented project is an open and controlled single-center prospective exploratory study, evaluating the metabolic concentrations in the ventral striatum (VS), the Anterior cingulate cortex (ACC) and the prefrontal cortex (PFC) on the left and on the right of patients in remission of unipolar mood disorder and type II bipolar mood disorder compared to each other and to healthy subjects using NMR spectrometric measurements. We hypothesize that there is a significant difference between the mean glutamate concentrations in the ventral striatum (right and left) of the two groups of unipolar and bipolar type II patients. The average glutamate concentration would be higher for participants in the group of type II bipolar patients.
Detailed Description
Depression meets the same clinical diagnostic criteria whether it is the expression of a bipolar or unipolar mood disorder. It is essential to distinguish between these two disorders because the pharmacological management of this episode and the follow-up of the patient will be different. The risk of iatrogenesis is significant if the diagnosis is incorrect. Currently, there is no biomarker that can help the clinician in his diagnostic approach and to differentiate between bipolar and unipolar mood disorder (Grande et al., 2016; Vieta et al., 2018). Many research, particularly in neuroimaging, explore these mood disorders to identify morphological, functional and metabolic signatures both in the state phase and in the asymptomatic phase. Functional imaging work, carried out at the Cardiff University Brain Research Imaging Center in Wales in collaboration with the team 7280 from Clermont Auvergne University, is part of this research. The object of this work was to study the dopaminergic system, and in particular the meso-cortico-limbic pathway, which is the anatomical and functional substrate of the reward circuit. The activity of this system, when measured on functional MRI in the ventral striatum during an activation paradigm of the "anticipation of a reward during a monetary task" type, shows variations in the disorders of mood, in the state phase as well as in the asymptomatic phase. These activation differences are significantly different between healthy, unipolar and bipolar asymptomatic subjects. The cerebral neurochemical processes involved in the physiopathology of mood disorders being still little studied at the present time and in order to complete these observations, the measurement and comparison of the concentrations of metabolites by NMR spectroscopy in these same regions (the meso -cortico-limbic) and under these same conditions will make it possible to specify the physiopathology of mood disorders. NMR spectroscopy, unlike functional MRI, allows us not only to compare groups, but also to measure concentrations in absolute values. Data from the literature show that these explorations are feasible in humans and meta-analyses suggest that a direct comparison could make it possible to discriminate mood disorders by the clinical dimension "capacity to experience pleasure" - or "hedonic capacity". We hypothesize that there is a significant difference between the mean glutamate concentrations in the ventral striatum (right and left) of the two groups of unipolar and bipolar type II patients. The average glutamate concentration would be higher for participants in the group of type II bipolar patients. This exploratory study will allow a better understanding of the pathophysiological mechanisms involved in the development of mood disorders and in particular in their clinical dimension "hedonic capacity", as well as to test the relevance of this potential biomarker (glutamate) than the current state of Art allows us to consider. The measurements in the control group will allow us to approach the values of the physiological norm. The measurements in the clinical groups will allow us to understand whether the "mood disorder" condition, even in remission, constitutes a sufficient factor of variation in this standard to allow them to be detected. This work would represent a first fundamental step in the understanding of pathophysiological mechanisms and the establishment of this measure as a biomarker for screening mood disorders and for discriminating between a unipolar disorder and a bipolar disorder and could thus guide the clinician in his diagnostic and therapeutic approach. The constraints for the participants will be minimal with only two visits to the CHU. A first for the inclusion of a duration of 60 minutes. A second for the 120-minute measurement visit. The inclusion of patients will be done if possible during their regular follow-up to limit travel. Since MRI is a non-invasive technique used routinely in hospital practice, the risks incurred by patients are almost nil, subject to compliance with the contraindications of MRI

Intervention Description
The MRI protocol will be carried out at 3 Tesla (3T) on a Siemens NMR imaging system (Magnetom Vida, Siemens Healthcare, Erlangen, Germany), the emission of radiofrequency waves and the reception of the signal will be done using a resonator in quadrature head (64-channel phase-array antenna). The MRI protocol will take place in two phases: Realization of a morphological sequence for the identification of the zone of interest. Acquisition of a 1D NMR spectrum in the ventral striatum (right and left). Acquisition of a 1D NMR spectrum in the anterior cingulate cortex (right and left). Acquisition of a 1D NMR spectrum in the prefrontal cortex (right and left).
