NCT03606850

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.

Outcome Measures

Primary Outcomes (1)

  • Variation of the CSP between day 1 and day 28

    The difference in variation of the cortical silent period (CSP) between day 1 and day 28 in responders compared to non-responders. A decrease by at least 50% on Hamilton Depression rating Scale (HAMD-21) define response to citalopram.The HAMD-21 assesses the intensity of the depressive symptoms with 21 items. Its score is between 0 (no depression) and 73 (the maximum of intensity).

    28 days

Secondary Outcomes (8)

  • Variation of the RMT between day 1 and day 28

    28 days

  • Variation of the MEP between day 1 and day 28

    28 days

  • Variation of the ICI between day 1 and day 28

    28 days

  • Variation of the ICF between day 1 and day 28

    28 days

  • Variation of the markers of cortical excitability at other times

    14 days

  • +3 more secondary outcomes

Study Arms (1)

Treatment by citalopram

EXPERIMENTAL

The patients will receive a treatment by citalopram at 20mg/day. If patients respond by at least 20% on the HAMD-21 scale at day 14 : continuation at 20 mg/day. If patients do not respond by at least 20% at day 14 : increase the dose at 40 mg/day. The patients who will not respond by at least 50% on the HAMD-21 scale at day 28 will be excluded of the study and will undergo a new treatment plan. The patients who will respond by at least 50% on HAMD-21 at day 28 will continue citalopram at the same dose and will be reappraised at day 60. The patients will be assessed for the markers of neuroexcitability at day 1, day 3, day 7, day 14, day 28 and day 60.

Device: Measurements of markers of cortical excitability by TMS

Interventions

In the arm experimental "treatment by citalopram", measurements of markers of cortical excitability by Transcranial Magnetic Stimulation will be applied. These measurements were: the cortical silent period CSP, the evoked potential MEP, the intra-cortical inhibition ICI and the intra-cortical facilitation ICF). Electromagnetic coil is placed upon the vertex, according to the International 10-20 EEG system. Gathering of the peripheral signal by a surface EMG electrode (non invasive device) placed regarding one of the first dorsal interosseous muscle.
