Developing Brain Imaging Analysis Expertise for Personalizing Transcranial Electric Stimulation in Anhedonia Treatment of Patients With Bipolar Depression
The University of Texas Health Science Center, Houston
Start Date
10/6/2022
Completion Date
12/1/2026
Summary
The purpose of this study is to investigate whether transcranial direct-current stimulation (tDCS) will engage reward-related brain circuitry, more specifically the uncinate fasciculus (UF) tract, which connects the orbitofrontal cortex (OFC) and nucleus accumbens (NAcc) regions. Also to evaluate whether the changes in the fractional anisotropy (FA) of the UF tract are associated with changes of clinical symptoms of anhedonia and finally to investigate the moderation role of simulated electric fields (EFs) in an association between FA of the UF and symptoms of anhedonia.
