Summary

This study aims to better understand the mechanisms of action of antidepressants, but also the neural correlates of motivation deficits. One hundred patients with a moderate to severe major depressive episode will be enrolled in this prospective multicenter study. The objective will be to predict the therapeutic response to two first-line antidepressants on the basis of an early neurocomputational assessment of motivation. Antidepressant treatment will be administered as monotherapy after randomization between two drugs: escitalopram and vortioxetine. Patients will undergo six visits and follow-up for one year. The investigators will combine computer modeling and functional MRI to identify motivational deficits and elucidate their brain correlates before initiation, after 7 days and after 6 months of treatment. 36 healthy volunteers will also be included to allow comparison with patients with depression. They will not receive any treatment.

Conditions

Interventions

OTHER

escitalopram

Patients will receive an antidepressant strategy : escitalopram. The strategy will not be modified for a period of 4 weeks. Dosage adjustment and co-prescriptions will be at the discretion of the refeering psychiatrist. After 4 weeks, the strategy can be adapted by the refeering psychiatrist exactly as if the patient had not been included in the trial.

OTHER

vortioxetine

Patients will receive an antidepressant strategy : vortioxetine. The strategy will not be modified for a period of 4 weeks. Dosage adjustment and co-prescriptions will be at the discretion of the refeering psychiatrist. After 4 weeks, the treatment strategy can be adapted by the refeering psychiatrist exactly as if the patient had not been included in the trial.
