No results posted yet for this study

Summary

The purpose of this study is to determine if repetitive transcranial magnetic stimulation (rTMS) applied to angular gyrus (AG) will improve negative symptoms and/or other psychosis symptoms in schizophrenia spectrum disorders (SSD) patients compared with prefrontal cortex (PFC) or sham.

Conditions

  • Schizophrenia Spectrum Disorder

Interventions

DEVICE

TMS

A wire coil is held on the scalp. Brief electrical currents are passed through the coil and create one or more magnetic pulses that stimulate the brain. For each TMS session, bursts of 3 pulses at 50 Hz are repeated at 5 Hz as a train for 2seconds. The inter-train interval is 8 seconds. There are 20 trains lasting 192 seconds (600pulses) per session. The intensity of TMS stimulations is set to 80-120% of resting motor threshold(RMT).

DEVICE

sham

Participants will receive total of 2 s of theta burst sham stimulation (TBS) trains repeated every 10 s for a total of 20 cycles (600 pulses). No actual magnetic stimulation will occur, still participant hears the TMS sound and a skin sensation
