A Novel Neurorehabilitation Approach for Cognitive Aging With HIV
A study testing transcranial direct current stimulation (tDCS) in people with HIV and Aging, run by University of Alabama at Birmingham at 1 site in United States.
Trial 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… Read more about this study

About this study
Official title: Speed of Processing Training With Transcranial Direct Current Stimulation in Older HIV+ Adults (HtDCS)
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
transcranial direct current stimulation (tDCS)Device
Also called transcranial electrical stimulation (tES)
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.
| Study group | Role | What they receive |
|---|---|---|
| Sham tDCS + Cognitive Remediation | Active comparator | Subjects in the sham arm will be administered sham transcranial direct current stimulation (tDCS) (i.e., tDCS will be administered for 30 seconds and then will automatically turn off). Sham group will have identical intervention of engagement in 10 1-hour computerized cognitive remediation therapy sessions during sham tDCS as with the active tDCS condition. Receives: Device: transcranial direct current stimulation (tDCS) |
| Active tDCS + Cognitive Remediation | Experimental | Subjects in the active arm will be administered active transcranial direct current stimulation (tDCS) (i.e., 2.0 mA tDCS will be administered for 20 minutes and then will automatically turn off). Active group will have identical intervention engagement in 10 1-hour computerized cognitive remediation therapy sessions during active tDCS as with the sham tDCS condition. Receives: Device: transcranial direct current stimulation (tDCS) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the Processing of Speed
Computerized and paper \& pencil processing speed measures were used to evaluate this outcome. The Letter and Pattern Comparison Tasks are traditional paper and pencil (SOP) measures. Specifically, they assess perceptual speed. In Letter Comparison subjects are shown three sets of 32 pairs of letters containing 3, 6, or 9 segments. The participants are instructed to decide whether the patterns between the pairs are the same or different within each set, with a time limit of 20 sec per set. Pattern Comparison also presents three sets of 32 pairs of patterns with 3, 6, or 9 line segments. Similarly, participants are instructed to decide whether the patterns are the same or different within the 20 sec time limit. For each measure, the total score is the number of correct answers from all three sets. Larger scores indicate better reasoning and cognitive functioning. In this study scores from Letter and Pattern Comparison were combined for a total Letter/Pattern Score.
Measured: baseline, 6 week posttest
Secondary outcomes (1)
Change in Driving Simulator Performance
Driving Simulator Performance: Center lane crossings (a count of how many times an individual crosses the centerline during the entire simulator drive). A difference score was taken between time 2 and time 1 and compared between treatment groups (sham condition and tDCS condition). A negative difference score indicates that fewer center line crossings were made at time 2 than time 1, while positive difference scores indicate the opposite direction, and scores of 0 represent no change.
Measured: baseline, 6 week posttest

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.
