Clinical Trial Summary

The main objective of this study is to demonstrate that 15 transcranial direct current stimulation (tDCS) sessions of 30 minutes at 2 mA intensity are effective to reduce suicidal ideation

Description:

After being informed about the study and potential risks, all patients giving written informed consent will undergo a screening visit to determine eligibility for study entry. Patient who meet the eligibility requirements be able to start the 15 tDCS sessions at the rate of one session per day. After the last session, patients will perform three follow-up visits on D19, D49 and D79

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from Baseline in suicidal ideation on the Scale for Suicide Ideation (SSI) at "Day 19"	The main judgment criterion is the evolution of suicidal ideation which is evaluated by the Beck Scale for Suicide Ideation (SSI) between Baseline and "Day 19"	Baseline and "Day 19"
Secondary	Change from Baseline of clinical response defined by the MADRS (Montgomery and Asberg depression scale) at "Day 19" post-tDCS sessions	The Montgomery-Åsberg Depression Rating Scale (MADRS) was developed to provide an assay of depressive symptom severity for use in the investigation of treatment response to antidepressant medication. The MADRS takes 20-60 minutes to be completed by interview. MADRS-S has 9 items , and each item is scored between 0 (minimum) and 6 (maximum). The scores for all 9 items were added, and cutoff scores for the MADRS-S were defined for level of depression (depression: 0-12 = minimal, 13-19 = mild, 20-34 = moderate, = 35 = severe).	Baseline and "Day 19"
Secondary	Change from Baseline of clinical response defined by the MADRS (Montgomery and Asberg depression scale) at "Day 49" post-tDCS sessions	The Montgomery-Åsberg Depression Rating Scale (MADRS) was developed to provide an assay of depressive symptom severity for use in the investigation of treatment response to antidepressant medication. The MADRS takes 20-60 minutes to be completed by interview. MADRS-S has 9 items , and each item is scored between 0 (minimum) and 6 (maximum). The scores for all 9 items were added, and cutoff scores for the MADRS-S were defined for level of depression (depression: 0-12 = minimal, 13-19 = mild, 20-34 = moderate, = 35 = severe).

Secondary	Change from Baseline of clinical response defined by the MADRS (Montgomery and Asberg depression scale) at "Day 79" post-tDCS sessions	The Montgomery-Åsberg Depression Rating Scale (MADRS) was developed to provide an assay of depressive symptom severity for use in the investigation of treatment response to antidepressant medication. The MADRS takes 20-60 minutes to be completed by interview. MADRS-S has 9 items , and each item is scored between 0 (minimum) and 6 (maximum). The scores for all 9 items were added, and cutoff scores for the MADRS-S were defined for level of depression (depression: 0-12 = minimal, 13-19 = mild, 20-34 = moderate, = 35 = severe).	Baseline and "Day 79"
Secondary	Change from Baseline in suicidal ideation assessed by the implicit association test at "Day 19" post-tDCS sessions	The Implicit Association Test (IAT) is a computer-based test measuring implicit mental associations between two concepts. The IAT uses reaction times to categorize stimuli that appear in the middle of the screen into two target categories, in our study: "Death" (suicide, dies, funeral, lifeless, deceased) and "Life". (survive, grow, breathe, alive, live) and/or in two attribute categories "Me" (me, myself, my, mine, I) and "Not Me" (them, they, their, his, others) . and subjects rapidly classify them by pressing one of two keys (the category of right (by pressing the I key) or left (by pressing the E key). According to the logic of the IAT, "D positive" scores represent a strong implicit association between "Me" and "Death". We will use Greenwald's improved algorithm to analyze responses.

Secondary	Change from Baseline in quality-of-life assessed by the SF36 (Short Form (36) Health Survey) at "Day 19" post-tDCS sessions	The Medical Outcomes Study Questionnaire Short Form 36 Health Survey (SF-36) is an indicator of overall health status. The SF-36 is validated and has eight scaled scores; the scores are weighted sums of the questions in each section. Scores range from 0 - 100, so that the lowest and highest possible scores are 0 and 100, respectively. Lower scores = more disability, higher scores = less disability. Sections : vitality, physical functioning, bodily pain, general health, perceptions, physical role functioning, emotional role functioning, social role functioning, mental health.
