ABSTRACT
The present study consists of the application of 1 ma anodal HD tDCS over the preSMA for 20 minutes a session for 10 sessions over a two week period. The treatment is hypothesized to lead to improvement in verbal retrieval, detectable in both performance measures of verbal retrieval tasks and in ERP markers of verbal retrieval processing. Our objective is to determine if 10 sessions of 1 ma anodal HD tDCS to the preSMA for 20 minutes a session are an effective treatment for verbal retrieval deficits in GWI. We have established the research team, laboratory setting, obtained approval of all regulatory documents for the study, and established recruiting procedures. In the first half of the year, we screened 8 veterans and enrolled 5 in the baseline testing and treatment phase of the study. We were required to halt in person human subject research for the second half of the year due to the Covid-19 pandemic.
