简要总结
Repetitive transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) has been used for the modulation of mild cognitive impairment (MCI) patients' cognitive function by altering the cortical excitability. Recently, more challenging approaches, such as stimulation of two or more sites or use of dual modality have been studied in MCI patients. In this study, simultaneous stimulation using both facilitatory rTMS (10Hz) and anodal or cathodal tDCS (dual-mode stimulation) over bilateral dorsolateral prefrontal cortices (DLPFCs) was investigated to compare its modulatory effects with single facilitatory rTMS stimulation in mild cognitive impairment patients.

研究组 & 干预措施
Experimental 1: Anodal Dual-mode stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of anodal tDCS on the right DLPFC.
Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired.
干预措施: High-frequency rTMS on left DLPFC+anodal tDCS on right DLPFC (Device)
Experimental 2: Cathodal Dual-mode stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of cathodal tDCS on the right DLPFC.
Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired.
干预措施: High-frequency rTMS on left DLPFC+cathodal tDCS on right DLPFC (Device)
Active Comparator: Single sham stimulation
10Hz of rTMS was applied over the left DLPFC for 10 minutes with simultaneous application of tDCS with sham mode (no stimulation) on the right DLPFC.
Each participant's 2-back verbal/nonverbal working memory task and variety cognitive function test are assessed and their resting-state fMRI data at three times: prior to stimulation (pre-stimulation), immediately after stimulation (post-stimulation) and 2 months after stimulation (f/u) are acquired.
干预措施: High-frequency rTMS on left DLPFC+sham tDCS on right DLPFC (Device)
