|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Primary Purpose: Treatment
|Official Title:||Investigation of Efficacy and Response Speed of a Combination Treatment of Escitalopram and Repetitive Transcranial Magnetic Stimulation|
- Evaluation of efficacy and response speed of an Escitalopram-rTMS-combination in the acute treatment of Major Depression.
- To determine the changes of hippocampal metabolites measured by MRS
- To assess the changes of parameters of motor cortical inhibition measured by MEP
- To assess the changes of NGF and BDNF
- To determine the changes of event related potentials measured by electroencephalography

We intend to test in a randomized, rater blinded, placebo controlled, prospective study the primary hypothesis that an escitalopram-rTMS-combination treatment is more efficacious in the treatment of refractory major depression assessed with the Hamilton Depression Rating Scale compared to placebo.
A second hypothesis is that the treatment of MDE with escitalopram (that means in the "Placebo group") alone lead to typical changes like
- An increase in neurotrophic factors concentration (measured by blood concentrations of nerve growth factor (NGF) and brain derived nerve growth factor (BDNF),
- An increase in hippocampal metabolites (measured with magnetic resonance spectroscopy (MRS
- An increase in motor cortical inhibitory activity (measured with motor evoked potentials (MEP
- An increase in serotonergic activity (measured with EEG parameters, Moreover, it is hypothesized that similar but pronounced changes occur in the group treated with the combination treatment.
