In this study, patients diagnosed with a depressive syndrome and with a clinical indication for treatment will receive an acute course of transcranial magnetic stimulation (TMS). The treatment consists of 20 TMS sessions administered over a period of four weeks (five sessions per week).
Magnetic resonance imaging (MRI) will be performed at four time points: prior to the start of treatment, after 10 treatment sessions, after completion of all 20 sessions, and at a three-month follow-up after the end of treatment. The MRI data will include different imaging modalities to assess treatment-related neurobiological changes.
The primary objective is to investigate changes in neuroimaging markers over the course of TMS treatment and to examine their associations with clinical response and behavioral as well as clinical outcome measures. Another key goal of the study is the identification of markers allowing for early prediction of treatment response to TMS and, additionally, for the prediction of relapse at follow-up.
