About this study

Official title: Structural-functional Brain Changes in Severely Depressed Patients Before and After Treatment With Electroconvulsive Therapy: an Exploratory Study

Electroconvulsive therapy (ECT) is a non-pharmacological treatment used in resistant depression whose effectiveness has been demonstrated. However, the brain mechanisms underlying this therapeutic effect remain unclear. Many animal studies show a neurotrophic action of ECT on the hippocampus: increased neurogenesis, synaptogenesis, proliferation of glial cells. In addition, functional imaging of "resting state" type have shown, among depressed patients after ECT, increased functional connectivity . These results were reinforced by the recent work of Perrin (2012). In view of this a priori contradictory, it seems appropriate to continue research neuroanatomical correlates subtending neurofunctional processes responsible at the same time improving the clinical depressive. The investigators suggest using an original technique never used in this type of population: Functional magnetic resonance imaging (fMRI) or multimodal structural-functional. This method will allow us to study the impact of ECT on brain structures involved in major depressive disorder: hippocampus.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 3T MRIDevice

    Four visits will be conducted during the prospective follow during which will be carried out a 3T MRI examination, assessment of assessment of depressive symptomatology and anterograde memory: within 7 days prior to the first session of ECT, within 48 hours after the first ECT session, within 48 hours after the first effective ECT session and within 10 days of the last session of ECT.

Study groupRoleWhat they receive
Severly depressed patientsExperimentalRecruitment of twenty depressive subjects will be conducted within the hospital service adult psychiatry.These patients are referred for indication of ECT sessions for severe resistant depression. Four MRI evaluations (3T MRI examination) are programmed in such patients to analyze structural changes in the hippocampus.

    Measured: Within 10 days after remission.

  6. Morphological changes in the hippocampus and hippocampal-related networks related to ECT between baseline and after remission as assessed by

    Measured: Within 10 days after remission.

  7. Functional changes in the hippocampus and hippocampal-related networks related to ECT after remission as assessed by measure of connectivity in multimodal MRI.

    Remission is defined by a score of 7 or less on Hamilton Depression Rating Scale (HDRS).

    Measured: Within 10 days after remission

  8. Evolution of Real Life/Real Impact-16 (RLRI-16) score after the first ECT, after ECT first "effective" and after remission

    RLRI-16 test will be realised during all visits, after ECT.

    Measured: Within 7 days before first ECT, after the first ECT, within 48 hours after the first effective ECT and within 10 days after remission

  9. Changes in the intensity of depressive symptoms score (Hamilton Depression Rating Scale) after the first ECT, ECT first "effective" and after remission

    Hamilton Depression Rating Scale will be realised during all visits, after ECT.

    Measured: Within 7 days before first ECT, after the first ECT, within 48 hours after the first effective ECT and within 10 days after remission

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Morphological changes in the hippocampus between baseline and after the first ECT effective session as assessed by volume measure in multimodal MRI. (time frame: Within 48 hours after the first effective ECT session.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02715986, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2020.
