NCT03026036

Brief Summary

This study investigates stress-related signaling of glutamate and dopamine within the reward-processing circuit in Major Depressive Disorder (MDD), and whether they can be used to predict depressive symptoms in the future. This will be achieved through various neuroimaging tools (MRS, fMRI, PET), behavioral tasks, and a naturalistic follow-up design.

Outcome Measures

Primary Outcomes (7)

  • Behavioral Performance on the Probabilistic Stimulus Selection Task

    The Probablilistic Reward Task operationalizes positive reinforcement learning

    Screening visit (Day 0)

  • MRI Data

    MRI scans for a total of 90 minutes take place within 30 days of Screening Visit

  • PET scan with raclopride

    a total of 90 minutes take place after the MRI data collection

  • Salivary Cortisol

    6 times during MRI visit (on or before Day 30), and 4 times during PET visit (on or before Day 30)

  • Four Blood Samples (6ml)

    During the MRI visit (on or before Day 30)

  • Follow-up Clinical Interviews

    6 months and 12 months after the MRI scanning visit

  • Behavioral Performance on the Instrumental Learning Task

    The instrumental learning task is designed to measure participant learning from reward and punishment.

    Administered during MRI scan (on or before Day 30)
