Outcome Measures

Primary Outcomes (2)

  • Repeatable Battery for the Assessment of Neuropsychological Status for cognition

    cognitive performance

    8 weeks

  • Positive and Negative Syndrome Scale for clinical symptoms

    clinical symptoms

    8 weeks

Secondary Outcomes (1)

  • Treatment Emergent Symptoms Scale for side effects

Study Arms (3)

10 Hz treatment group

EXPERIMENTAL

In active rTMS, 10 Hz stimulations over left DLPFC occurred at a power of 110% of MT for 27-s intervals with 20s inter-train interval. 20 minutes were administered each day (Monday-Friday) for 8 consecutive weeks.

Device: 10 Hz treatment group

20 Hz treatment group

EXPERIMENTAL

In active rTMS, 20 Hz stimulations over left DLPFC occurred at a power of 110% of MT for 20 intervals with 28s inter-train interval. 20 minutes were administered each day (Monday-Friday) for 8 consecutive weeks.

Device: 20 Hz treatment group

Control Group

SHAM COMPARATOR

In sham rTMS, all procedures were identical to 10Hz group except they were the non-magnetized steel cylinders, instead of cylindrical magnets, that were rotated.

Device: Control Group
