Speed of Processing Training With Transcranial Direct Current Stimulation in Older HIV+ Adults (HtDCS)
In Brief
A clinical study evaluating transcranial direct current stimulation (tDCS) for HIV and Aging. Completed, enrolled 42 participants across 1 site.
Detailed Summary
The goal of this study is to conduct a small, self-contained project to test the hypothesis that tDCS will augment SOP cognitive remediation therapy (CRT) in older HIV+ adults. The investigators will randomly assign 60 HIV+ older adults (i.e., ≥ 50 years old) to 10-hours in either a SOP CRT + sham tDCS condition (n=30) or SOP CRT + active tDCS condition (n=30) and examine neurocognitive functioning at baseline and 6 weeks post-intervention. Hypothesis 1: The SOP CRT + active tDCS condition will show larger proximal (i.e., SOP) gains than the SOP CRT + sham tDCS condition. Hypothesis 2: The active tDCS condition will demonstrate generalization to secondary neurocognitive domains compared to the sham tDCS condition.

Timeline
Interventions
tDCS is a low level electrical stimulation that will be applied to F10. The sham group will receive 2 mA (milliamps) for 30 seconds, while the experimental group will receive 2 mA for 20 minutes. Both groups will have 10, 1 hour sessions of playing cognitive remediation games, while receiving the respective level of tDCS for sham vs experimental conditions.
