Clinical Trial Summary

Can brain MRI at entry of cocaine inpatient cessation attempt predict relapse during a three month follow-up ? Hypothesis : White matter losses in the prefrontal cortex are associated with relapse to cocaine use.

Description:

A multivariate model using MRI parameters, craving score, impulsivity score, and neuropsychological testing results will be tested to predict relapse or continuous abstinence three month after cocaine inpatient cessation attempt.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	mean difference of fractional anisotropy of the prefrontal cortex (PFC) in patients abstinent from cocaine 3 months after inpatient detoxification compared to relapsers		at 3 months
Secondary	Comparisons between patients who remain abstinent from cocaine 3 months after inpatient detoxification and those who relapse	Differences in grey and white matter volumes : voxel-based morphometry (VBM) and in resting-state whole-brain activity default mode network (DMN)	at baseline
Secondary	Comparisons between patients who remain abstinent from cocaine 3 months after inpatient detoxification and those who relapse	Differences in scores of craving (visual scale and Obsessive compusilve craving scale (OCCS) questionnaire) and impulsivity (UPPS)	at baseline
Secondary	Comparisons between patients who remain abstinent from cocaine 3 months after inpatient detoxification and those who relapse	Differences in performance at the stroop test and in mental flexibility during an implicit set shifting task	at baseline
Secondary	Among abstinent patients who remain abstinent at three months only :Differences between baseline and 3 months measures of Diffusion Tensor Imagery (DTI), VBM and DMN		at 3 months
Secondary	Among abstinent patients who remain abstinent at three months only: Differences in scores of craving (visual scale and OCCS questionnaire) and impulsivity (UPPS)		at 3 months
Secondary	Among abstinent patients who remain abstinent at three months only: Differences in performance at the stroop test and in mental flexibility during an implicit set shifting task compared to baseline results		at 3 months
