Brief Summary
Sequential left prefrontal Repetitive Transcranial Magnetic Stimulation (rTMS), with high frequency, for Treatment-Resistant Depression have been shown to have antidepressant effects. but doubts remain about the magnitude of previously demonstrated treatment effects.The aim of this study is To test whether daily weekday left prefrontal rTMS safely and effectively treats Resistant Depression disorder compared to sham controls.

Outcome Measures
Primary Outcomes (1)
change (decrease) of depression according to Hamilton, Beck, BPRS questionnaires.
The primary outcome measure for the study was score on the MADRS. The patients were assessed with the MADRS, the 17-item version of the Hamilton Depression Rating Scale (HAM-D), the Beck Depression Inventory (BDI), the Brief Psychiatric Rating Scale (BPRS), the CORE Rating of Psychomotor Disturbance (16), and the Global Assessment of Functioning (GAF) Scale (DSM-IVTR).

Study Arms (2)
Repetitive Transcranial Magnetic Stimulation
ACTIVE COMPARATORWe deliver rTMS to the left prefrontal cortex at 120% motor threshold (10 Hz, 4-second train duration, and 26-second intertrain interval) for 37.5 minutes (3000 pulses per session) using a figure-eight solid-core coil.
Sham rTMS
SHAM COMPARATORSham rTMS using a similar coil with a metal insert blocking the magnetic field and scalp electrodes that delivered matched somatosensory sensations.
