Clinical Trial Summary

Suicidal behaviors (SB) are a major health problem in France : 10 000 suicides and 220 000 suicide attempts every year. SB management is therefore a major public health issue. Evidence associated dysregulation of the serotonergic system and the hypothalamic-pituitary-adrenal axis to vulnerability to SB. Recent data point to linke these abnormalities with neuroinflammatory clues, glutamatergic function and neuronal plasticity. There is a need to better understand the physiopathology and develop diagnostic and therapeutic tools in SB. The investigators hypothesize that increased peripheral biomarkers of inflammation would correlate to a disturbance of the cerebral metabolites, such as glutamate and NAA, especially in suicidal patients. Our aim is to compare rates of cerebral metabolites, in particular the complex glutamine/glutamate, in cerebral areas involved in suicidal vulnerability (the anterior cingulate cortex and the orbito-frontal cortex) between person with unipolar disorder with and without suicidal attempt.


Clinical Trial Description
