Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study aims at investigating if tDCS applied to left DLPFC or to right OFC to treatment as usual is effective in reducing severe suicidal ideas in major depressive episode.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Depressive disorders are one of the most frequent pathologies in psychiatry. The lifetime prevalence of the characterized depressive episode is indeed particularly high, between 16.6% in the United States and 24.1% in France. Because of this high prevalence, and because they constitute a pathology with a high risk of suicidal behavior (SC), depressive disorders are a major target of medical strategies for suicide prevention. In addition to suicidal ideation, impulsivity, considered as the tendency to express spontaneous, excessive and/or unplanned behaviors, is recognized as being a major factor precipitating SCs.

With a pilot, prospective, multicenter design, the perspectives of DEPIMPULSE include being able to develop an innovative therapeutic approach in the reduction of risky behaviors, in particular suicidal ideation, associated impulsivity, suicidal risk in patients suffering from depression, while improving our understanding of the behavioral aspects and associated cognitions.

The treatment will be delivered during 5 consecutive days (D1 to D5).

Baseline measures (D0) will be compared to those obtained after the treatment administration (last day of treatment (D5) and 2 weeks (+W2) and 1 month (+W4) after the end of treatment.
