Clinical Trial Summary

Stress reduction methods based on mindfulness meditation have been experiencing significant growth in various fields of society over the past twenty years. In the case of students, scientific work has shown that mindfulness training has a positive effect on their mental health and possibly on their academic performance through improved attention and memory. The effect of metamemory ("knowing what you know and what you don't know"), which plays an important part in students memorization and academic success, has not yet been explored.

Changes in brain structure have been noted by MRI in some regions after several weeks of mindfulness training, but very few studies have yet looked at changes in brain metabolism that can be observed by the spectrocopy technique.

The investigators will conduct a prospective randomized study with overall 30 female speech therapists student that will be enrolled and assigned randomly to two groups, in a 1:1 ratio : one groupe that will benefit from mindfulness training and the other group that will benefit from another method of stress reduction based on muscular relaxation.

The programs will extend over 6 weeks with session of 2h30 per week in groups having personnal daily exercices (30-40' per day). During the 3 weeks leading up to and the 2 weeks following the program, students will take tests exploring memory and metamemory, complete mental health questionnaires, and have a magnetic resonance imaging with spectroscopic analysis.

Clinical Trial Description

The main objective of this study is to investigate the effects of a mindfulness based stress reduction (MBSR) program on the metabolism of regions involved in memorization (several limbic regions : hippocampus, amygdala, anterior and posterior cingulate)

The study also aims to :

1. Study the effects of MBSR program on memory and metamemory.

2. Study correlations between MBSR program effects on metamemory and scores on mental health scales (anxiety, depression, perceived stress, burnout)

3. Study the correlations between MBSR program effects on memory and metamemory with those on attentional capacities, working memory, executive functions and emotion regulation

4. Investigate the relationship between brain metabolites variations and the effect of the MBSR program on episodic memory and metamemory capacities, attention and emotions

5. Investigate the relationship between metabolite concentrations variations and variations in volume and thickness of the cortex. ;
