Summary

As we age, a number of factors can reduce our cognitive (or thinking) abilities. This study will evaluate whether transcranial electrical stimulation (TES), which uses small amounts of electricity to modulate brain functioning, can improve cognitive abilities. Here, the effects of TES on working memory, learning, and memory, will be evaluated in a group of healthy older adults.

Detailed description

The primary objective is to investigate the cognitive effects of high definition anodal tDCS (HD-tDCS; anode at center electrode) at 3 mA (for 20 minutes) on learning, memory, and working memory. Participants will be randomized to active or sham stimulation and will complete a series of cognitive tests both during and after stimulation. Tolerability and blinding will also be evaluated using standard side effect questionnaires.
