Brain Markers of Suicide Risk and Psychological Pain in Elderly Depressed Patients

Completed

• Conditions: Depressive Disorder; Suicide, Attempted
• Interventions: Other: MRI

• Registration Number: NCT03287986
• Lead Sponsor: Centre Hospitalier Universitaire de Nīmes

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).

Arm && Interventions

Group	Intervention	Description
Patient controls	MRI	depressed patients over 60 years of age without a personal history of suicide attempt scanned with MRI
Healthy Controls	MRI	Healthy subjects over 60 years, not depressed and without personal history of severe mental illness or suicide attempts, scanned with MRI
Suicide attempters	MRI	Depressed patients over 60 years of age with a personal history of suicide attempts scanned with MRI

Primary Outcome Measures

Name	Time	Method
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

Name	Time	Method
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
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
