Schizophrenia Clinical Trial
Official title:
Optimizing Treatment Protocol of High Frequency Repetitive Transcranial Magnetic Stimulation for Cognitive Deficits and Negative Symptoms in Schizophrenia: an Exploratory Study
Negative symptoms and cognition decline are major challenges in clinical management of schizophrenia. Dorsomedial prefrontal cortex (DLPFC) has been highly involved in the mechanisms of negative symptoms and cognitive symptoms of schizophrenia. However, the effect of repetitive transcranial magnetic stimulation (rTMS) over left or bilateral DLPFC has not yet been well studied. The aim of this study is to describe how the effectiveness of rTMS over different targets for cognitive deficits and negative symptoms in schizophrenia will be evaluated. The study will provide evidence to determine whether a bilateral DLPFC rTMS and is more effective than a left DLPFC rTMS alone to optimize treatment protocol in schizophrenia.
The study will be a randomized, double-blind trial comparing active rTMS over bilateral DLPFC vs. active rTMS over left DLPFC vs. sham rTMS delivered over DLPFC an 4-week treatment period. After assessment and inclusion into the study, participants will be randomized to receive up to 20 sessions of either active rTMS over left DLPFC or bilateral DLPFC or placebo treatments. ;
