Noninvasive Dual-mode Stimulation Therapy for Neurorehabilitation in Mild Cognitive Impairment

September 19, 2019 updated by: Samsung Medical Center

Investigation for Individualized Noninvasive Neuromodulation in Mild Cognitive Impairment

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: 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.
Device: High-frequency rTMS on left DLPFC+anodal tDCS on right DLPFC
10Hz rTMS over the left DLPFC and anodal tDCS over the right DLPFC are simultaneously stimulated.
EXPERIMENTAL: 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.
Device: High-frequency rTMS on left DLPFC+cathodal tDCS on right DLPFC
10Hz rTMS over the left DLPFC and cathodal tDCS over the right DLPFC are simultaneously stimulated.
ACTIVE_COMPARATOR: 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.
Device: High-frequency rTMS on left DLPFC+sham tDCS on right DLPFC
10Hz rTMS over the left DLPFC and sham tDCS (no stimulation) over the right DLPFC are simultaneously stimulated.
