Trial Outcomes & Findings for Bilateral Repetitive Transcranial Magnetic Stimulation for Auditory Hallucinations Results (NCT NCT04548622)

NCT ID: NCT04548622

Last Updated: 2020-10-30

Results Overview

The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.The PANSS positive symptoms hallucinication score has a range of 1-7. Higher scores indicate more severe positive symptoms in patients with schizophrenia.

Measure
Non-randomized Bilateral rTMS
Active bilateral rTMS to left/right Wernicke's area and opposite side middle temporal gyrus Magstim Rapid 2 system triggering Magstim Super Rapid system: Week 1 treatment includes rTMS for 5 sessions to both the left and 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.

PRIMARY outcome

Timeframe: baseline to 4 weeks

The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia.The PANSS negative scale has 7 Items, with a minimum score of 7 and a maximum score of 49. Higher scores indicate more severe negative symptoms in patients with schizophrenia.
