SPAD-IRM: Brain Markers of Suicide Risk and Psychological Pain in Elderly Depressed Patients
Study Details
Study Description
Brief Summary
The main objective of this study is to show MRI functional and structural differences between depressed elderly patients with a history of attempted suicide compared to depressed elderly patients with no history of attempted suicide and to elderly subjects with no personal history of depression or attempted suicide (healthy controls).

Outcome Measures
Primary Outcome Measures
- Brain functional activity during unfairness [Day 0]
Contrast in BOLD signal measured by 3T-Magnetic Resonance Imaging (MRI) during the fair vs unfair trials of the Ultimatum Game
Secondary Outcome Measures
- Brain structural volumes [Day 0]
T1 sequence measured by MRI in each participant
- Brain structural connectivity [Day 0]
Diffusion Tensor Imaging measured by MRI in each participant
- Brain functional connectivity [Day 0]
Resting state activity measured by MRI in each participant
- Correlation of MRI measures with psychological pain measures [Day 0]
Psychological pain will be measured by the Visual Analog Scale (Olié et al. 2010) in each participant
