Brief Summary:
Depression is a common issue but there is no marker of response to an antidepressant treatment.The measurement of variation of the cortical excitability in responders to a selective serotonin reuptake inhibitor (SSRI) (compared to no-responders) had never been done before. In the study of Robol et al. (2004) concerning the acute effects of citalopram on markers of cortical excitability, the authors have pointed out an increase on the cortical silent period (CSP) after administration of citalopram (2.5 hours). The investigators hypothesize that this effect remains later and that the diminution of cortical excitability could be a biomarker of antidepressant response. In this case, they expect that the variation of CSP between day 1 and day 28 is higher in responders to a SSRI (citalopram) compared to non-responders. the investigators lead a pilot, prospective, multicentric study in drug-naive patients to compare the variation of the markers of cortical excitability (the CSP but to the resting motor threshold RMT, the motor evoked potential MEP, the intra-cortical inhibition ICI and the intra-cortical facilitation ICF) between day 1 and day 28 in responders to citalopram, compared to non-responders.
