Brief summary
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.
Interventions
10Hz rTMS over the left DLPFC and anodal tDCS over the right DLPFC are simultaneously stimulated.
10Hz rTMS over the left DLPFC and cathodal tDCS over the right DLPFC are simultaneously stimulated.
10Hz rTMS over the left DLPFC and sham tDCS (no stimulation) over the right DLPFC are simultaneously stimulated.
