Repetitive Transcranial Magnetic Stimulation (rTMS) as a Probe of Episodic Memory (EM) Neurocircuitry in Schizophrenia

Indiana University·interventional·Posted Dec 2, 2019·Updated Jul 28, 2023

In Brief

A clinical study evaluating 1 Hz rTMS Stimulation and Sham rTMS Stimulation for Schizophrenia. Completed, enrolled 25 participants across 2 sites.

Detailed Summary

This will be a single site pilot study. 30 subjects with Early Phase Psychosis (EPP), defined as medical record documentation of the onset of clinically significant psychotic symptoms within the past ten years, will be enrolled. Prior to randomization (Session 1), subjects will undergo Functional Magnetic Resonance Imaging (fMRI) during Episodic Memory (EM) and Resting State (RS) paradigms. This baseline scan will also include a high-resolution structural sequence for neuronavigation purposes. Then on three separate days each occurring one-week apart, subjects will receive one session of inhibitory (1 Hertz \[Hz\]) Repetitive Transcranial Magnetic Stimulation (rTMS), one session of excitatory (20 Hz) rTMS, and one sham stimulation session targeting the precuneus. The order of the three interventions will be randomized. Immediately following each rTMS or sham session, subjects will undergo repeat fMRI during EM and RS paradigms. The investigators will also examine the effect of rTMS on EM performance.

Interventions

1 Hz rTMS Stimulationdevice

rTMS is an electromagnetic device that provides non-invasive stimulation to the cortex or a sham placebo stimulation that mimics properties without stimulation.
