Effect of tDCS Timing on Safety Memory in PTSD
NCT04152772 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04152772
The ClinicalTrials.gov registry entry for NCT04152772 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 62 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Butler Hospital, which has 58 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with PTSD appearing as the primary indexed condition, and to 1 intervention — of which transcranial direct current stimulation is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04152772 reports 1 study location spanning 1 distinct geographic area — top geographies include Rhode Island. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
