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

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * diagnosis of Bipolar Disorder and clinically significant anhedonia
  • * mild symptoms of depression
  • * substance abuse/dependence and any use of drugs (except alcohol or nicotine) in the previous month of the baseline assessment
