Summary

This study is attempting to improve word finding and memory retrieval problems persons with mild cognitive impairment (MCI) may have.

Detailed description

This study attempts to improve word finding and memory retrieval problems in persons with mild cognitive impairment (MCI). To remember and find words, the brain has to search for the correct memory and MCI can negatively affect this search. Studies have suggested that low level electrical stimulation of the memory retrieval circuit can improve memory recall. The purpose of this study is to find the exact influence of multi-electrode or High Definition transcranial Direct Current Stimulation (HD-tDCS) by targeting a frontal and a parietal brain area, and their roles in memory retrieval/word finding in MCI. By modulating ongoing activity in 6 sessions of HD-tDCS the study investigates whether HD-tDCS may be used as a way to improve memory retrieval/word finding evaluated by cognitive measures and electroencephalography (EEG) measures before the first session and after the last session of HD-tDCS with a follow-up session 1-month after the stimulation procedure.
