Clinical Trial Summary

The overall objective of this project is to examine the effects of non-invasive brain stimulation on episodic memory performance


Clinical Trial Description

A group of 20 cognitively intact younger participants (age 21-35), a group of 20 cognitively intact older participants (age 55+) and an age-matched group of 20 MCI/mild AD participants will be enrolled in the brain stimulation study with behavioral assessments at baseline and post-intervention. All participants will perform a laboratory-based memory task and an autobiographical memory task, followed by the autobiographical interview after the tACS intervention. Each participant will undergo three experimental sessions, applying 20-minute gamma tACS stimulation, theta tACS stimulation or an active sham (control) to the left angular gyrus. Before, during, and after the brain stimulation scalp high-density 257-channels EEG will be recorded to characterize and differentiate brain activity and regional interactions in the three independent groups. ;
