Effect of tDCS Timing on Safety Memory in PTSD
In Brief
A clinical study evaluating transcranial direct current stimulation for PTSD. Completed, enrolled 62 participants across 1 site.
Detailed Summary
The primary purpose of this study is to investigate the effects of tDCS timing on extinction memory in PTSD. A total of 90 participants will be randomized equally across one of three groups: 1. One group receiving active stimulation during extinction followed by sham stimulation during consolidation 2. One group receiving sham stimulation during extinction followed by active stimulation during consolidation 3. One group receiving sham stimulation both during extinction and consolidation This study also includes an online sub-study (Aim 2) focused on contextual processing along the PTSD spectrum. The online study tests if there is an association between threat and non-threat learning in contextual and non-contextual situations. A maximum of 500 participants will be recruited using an online, panel-based platform.
Study Details
Timeline
Interventions
Active tDCS will consist of 15 minutes of 2 mA intensity once, either applied during or after extinction learning.
