5. Study Description
Brief Summary
The overarching goals of this study are to employ cognitive testing to understand how transcranial direct current stimulation (tDCS), when used concurrently with cognitive training tasks, can affect cognitive impairment symptoms in individuals with long COVID, or post-acute sequelae SARS-CoV-2 infection (PASC), and to examine variability in response between active and sham tDCS treatment groups.
