Primary Outcome Measures

Name	Time	Method
A 50% change of MADRS score	Day 60	The main objective is to demonstrate that dTMS is more efficient than high frequency rTMS with a conventional coil.; Modification of the MADRS score compared to baseline score. MADRS stands for Montgomery-Asberg Depression Rating Scale. It is used to measure the severity of depressive episodes in patients with mood disorders. The questionnaire includes questions on the following symptoms 1. Apparent sadness 2. Reported sadness 3. Inner tension 4. Reduced sleep 5. Reduced appetite 6. Concentration difficulties 7.
