Noninvasive Cortical Stimulation to Improve Memory in Mild Cognitive Impairment
In Brief
A clinical study evaluating Active rTMS (Bilateral DLPFC), Active rTMS (Bilateral LPC), and 1 other intervention for Mild Cognitive Impairment and 7 related conditions. Completed, enrolled 69 participants across 1 site.
Detailed Summary
The goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one of three treatment groups: Group 1: Active Dorsolateral Prefrontal Cortex (DLPFC) rTMS; Group 2: Active Lateral Parietal Cortex (LPC) rTMS; and Group 3: Inactive rTMS (Placebo) control (evenly split between each coil location). Participation in the study takes approximately 7 ½ months-including a 2-to 4-week treatment phase (20 rTMS sessions) and a 6-month follow-up phase.

Timeline
Interventions
TMS Stimulation Parameters for the active DLPFC rTMS intervention group will be: 10 Hz, 4-second train duration and 11-second inter-train interval. During each session, 2,000 pulses will be applied for each hemisphere (for a total of 4,000 pulses per session). Participants will receive 20 sessions (1 or 2 sessions per day, M-F).
TMS Stimulation Parameters for the active LPC rTMS intervention group will be: 10 Hz, 4-second train duration and 11-second inter-train interval. During each session, 2,000 pulses will be applied for each hemisphere (for a total of 4,000 pulses per session). Participants will receive 20 sessions (1 or 2 sessions per day, M-F).
For the Placebo rTMS (Inactive) group, the participant will wear scalp electrodes through which a low voltage, low electric current (2-20mA at no more than 100V) is passed to mimic the sensation of receiving actual rTMS. Participants will receive 20 sessions (1 or 2 sessions per day, M-F).
