Cognitive Outcomes of Brain Stimulation As a Later-in-Life Treatment

Brief Summary

This is a pilot study being done to attempt to improve episodic memory problems in persons with mild cognitive impairment (MCI). The pre-supplemental motor area (preSMA) and dorsal anterior cingulate cortex (dACC) have been shown to play a role in episodic memory and language retrieval. Prior studies have suggested that neurostimulation targeting this region can improve episodic memory and word recall. The purpose of this study is to examine the efficacy of high-definition transcranial direct current stimulation (HD-tDCS) to the preSMA/dACC region and its influence on word retrieval and other cognitive functions in patients with MCI. Entraining the preSMA/dACC circuit with 10 sessions of HD-tDCS will allow us to study whether neurostimulation may be an effective treatment.
