Theta-Burst Stimulation in Major Depressive Episodes With Mixed Characteristics.

Study Overview
=================
Brief Summary
-----------------
The investigators will perform a double-blind, randomized, sham-controlled clinical trial of theta-burst stimulation (TBS) in mixed depressive episodes of both bipolar and major depressive disorders. Will be selected 90 patients aged 18-65 years with diagnosis of TB (I or II) or MDD in moderate or severe major depressive episode with mixed features. The primary endpoint of efficacy will be a continuous outcome of change in Montgomery-Asberg Depression Rating Scale (MADRS) from baseline to week 3.

Detailed Description
-----------------
INTRODUCTION: Mixed-specifier mood disorders are probably a different subgroup in terms of response to treatment, socio-demographic parameters, course and family history. The investigators will perform a clinical trial of theta-burst stimulation (TBS) in mixed depressive episodes of both bipolar (I and II) and major depressive disorders. METHODS: The study is designed as a randomized, sham-controlled, double-blinded clinical trial evaluating TBS for the treatment of moderate or severe major depressive episodes with mixed features of patients receiving at least one first or second line pharmacological treatment for depressive episodes without adequate response. Ninety adult (18 to 65 yo) patients will be enrolled and submitted to 6-week (comprising 5 consecutive days a week sessions for the first 3 weeks and then 2 days a week for a further 3 week) of inhibitory followed by excitatory TBS in dorsolateral prefrontal cortex. Participants will be assessed using clinical and neuropsychological tests before and after the intervention. The primary outcome is change in Montgomery-Asberg Depression Scale (MADRS) score over time and across groups. Cognitive parameters will also be assessed with neuropsychological tests.
