Brief Summary

This research investigates the effect of active versus sham tACS paired with cognitive exercises in a regimen protocol of weeks, everyday. The study design is a one-time crossing over design in which participants are randomized into two groups: One group will receive active treatment for 4 weeks, then 8 weeks of no treatment followed by another 4 weeks of treatment but with sham. The other group will start with sham and end up with active treatment. The study is double-blind; thus, neither participants, nor the assessors know the group assignment. The Intervention is applying tACS either active or sham paired with cognitive exercises (MindTriggers app games). Note: The above study will run at both University of Manitoba (U of M) and Aster Gardens residence. However, at Aster Gardens Residence only questionnaire type of assessments will be run, while in U of M, the investigators will have three other major assessments as well. In addition, the investigators will run the assessments at the Aster Gardens Residence through online sessions.

Study Arms (2)

Group 1 (G1)

EXPERIMENTAL

Participants will receive active tACS simultaneously with cognitive exercises.

Device: transcranial alternative current stimulation (tACS)Other: cognitive exercises

Group 2 (G2)

SHAM COMPARATOR

Participants will receive sham tACS simultaneously with cognitive exercises.

Other: cognitive exercises

Interventions

A light electrical current will be applied to the scalp of the participants via 2 electrodes, while the participants performs cognitive exercises with the guidance of a trained research assistant.

Group 1 (G1)

Participant will perform memory and learning games/tasks through "Mind Triggers" app on an IPad. Participants will be guided by a highly trained research assistant.

Group 1 (G1)Group 2 (G2)

Masking Details
The group assignment is known only by the study coordinator and the PI. Group assignment will be randomized into either Group 1 or Group 2 using PROC PLAN procedure of SAS randomization. The group assignment of a participant could potentially be unblinded on compassionate ground (e.g., if a participant comes from a different city for the duration of the study) or request of the participant or any emergency situation (although very rare). In that case the participant's data may be excluded from the analysis totally or depending on when this unblinding occur, half of the data might be usable for analysis (if unblinding occur during the waiting period before crossing over). The unblinding decision will be made by the PI.

Intervention Model
CROSSOVER
Model Details: This human research study is a crossover, placebo controlled and double-blind study. It will have two groups of subjects matched in age, and sex and cognitive level (measured by Montreal Cognitive Assessment: MoCA). Group 1 (G1) participants will receive active tACS simultaneously with cognitive exercises. Group 2 (G2) participants will receive sham tACS simultaneously with cognitive exercises. The volunteers who cannot tolerate application of tACS and focus on the cognitive exercises at the same time, will be enrolled in a third group (G3); they will receive only cognitive exercises with the same protocol as in G1 and G2. We will use only two periods design (one time crossing over).
