Developing Brain Imaging Analysis Expertise for Personalizing Transcranial Electric Stimulation in Anhedonia Treatment of Patients With Bipolar Depression

Sponsored by The University of Texas Health Science Center, Houston

About this study

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.

Only the research team can confirm whether you qualify. The intake questionnaire is the best way to find out.

Completing a questionnaire on Clinably does not enroll you in a clinical trial or confirm your eligibility. Only the research team can determine whether you qualify to participate. These results are based on the information you provide and are intended to help you start a conversation with the research team.
