High-Definition Transcranial Direct Current Stimulation on Episodic Memory in Individuals With Amnestic Mild Cognitive Impairment and History of TBI

University of Texas Southwestern Medical Center·interventional·Posted Aug 7, 2020·Updated Jan 13, 2026

In Brief

A clinical study evaluating High Definition Transcranial Direct Current Stimulation and Sham HD-tDCS for Amnestic Mild Cognitive Impairment and 2 related conditions. Completed, enrolled 26 participants across 1 site.

Detailed Summary

The study will examine the efficacy of high definition transcranial direct current stimulation (HD-tDCS) and its influence on episodic memory in patients with amnestic mild cognitive impairment and a history of Traumatic brain injury. Ten sessions of HD-tDCS to the dorsal anterior cingulate region is expected to result in improvements in episodic memory measures immediately following the last session and at a 3-month follow-up.

Interventions

High Definition Transcranial Direct Current Stimulationdevice

This wireless device delivers a very low electrical current to focused regions on the scalp in order to modulate underlying brain circuits to promote neuroplasticity. The device will be fitted onto a neoprene EEG cap, with 1 anode electrode placed and surrounded by 4 cathode electrodes in a ring pattern. Electrical stimulation will be applied using a constant voltage cortical stimulator (Model D185, Digitimer Ltd, UK, maximal output 1000 V/1.5 A) with single square-wave 50-μs pulses (0.1 A/μs rise time).
