Bilateral Repetitive Transcranial Magnetic Stimulation for Auditory Hallucinations Original Study

NCT00567281 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Last updated 2020-09-17

No results posted yet for this study

Summary

This trial is designed to determine if administering repetitive transcranial magnetic stimulation (rTMS) simultaneously to two sites in the temporal lobes, one on the left and one on the right, produces greater improvements in "voices" and other symptoms of schizophrenia compared to rTMS given to just one site in the temporal lobes.

Conditions

Interventions

DEVICE

Magstim Rapid 2 system triggering Magstim Super Rapid system

Week 1 treatment includes rTMS for 5 sessions to either to left or right Wernicke's area (BA22) synchronous with rTMS to opposite hemisphere middle temporal cortex (BA21). Week 2 treatment includes rTMS given for 5 sessions with positions reversed (e.g., if Wernicke's stimulation was on the left during Week 1, position of rTMS will switch to the right side during Week 2 and vice-versa). As in Week 1, active rTMS will also be given synchronously to the opposite hemisphere middle temporal cortex. Weeks 3 and 4 include 10 stimulation sessions to the configuration of sites producing greater improvement in comparing results of Week 1 and Week 2. rTMS for each stimulation session will be given at 1-Hertz (once per second) for 16 minutes without interruption.

DEVICE

Magstim Rapid-2 system triggering Magstim Super Rapid system

Week 1 includes repetitive rTMS for 5 sessions to either to left or right Wernicke's area (BA22) synchronous with sham rTMS to opposite hemisphere middle temporal cortex (BA21). Week 2 includes rTMS given for 5 sessions with positions reversed (e.g., if Wernicke's stimulation was on the left during Week 1, position of rTMS will switch to the right side during Week 2 and vice-versa). As in Week 1, sham rTMS will also be given synchronously to the opposite hemisphere middle temporal cortex. Weeks 3 and 4 include 10 stimulation sessions to the configuration of sites producing greater improvement in comparing results of Week 1 and Week 2. rTMS for each stimulation session will be given at 1-Hertz (once per second) for 16 minutes without interruption.
