NCT04478032

Brief Summary

Based on the hypothesis that low-frequency deep transcranial magnetic stimulation(dTMS) on anterior cingulate cortex (ACC) could down-regulate the glutamate level of ACC and regulate the acc-related functional network in patients with treatment resistance schizophrenia,this research plan to utilise multimodal functional magnetic imaging method(including structural MRI,resting-state functional magnetic resonance imaging and 1H-MRS) to investigate therapeutic efficacy of low-frequency deep transcranial magnetic stimulation on SZ patients symptoms,as well as to elucidate the correlation between treatment effects and glutamate level of ACC
