Transcranial Direct-Current Stimulation for Anhedonia in Bipolar Depression

Principal Investigator: Jair C. Soares, MD, PhD

Study Description:

The purpose of this study is to investigate whether transcranial direct current stimulation (tDCS) therapy will reduce symptoms of depression and anhedonia (lack of pleasure) in people with bipolar disorder. tDCS is an investigational tool for non-invasive brain stimulation. It is a wearable device, similar to a helmet, which delivers low-level electrical signals to the outside of the scalp.

In addition to 14 sessions of tDCS therapy and two magnetic resonance imaging (MRI) scans of your brain, this 6–8-week long study includes clinical and laboratory evaluations assessing topics such as mood, medical and psychiatric diagnoses, and history.

Participants will be compensated for their time, totaling $650 by the end of their participation.

This study is currently looking for people who:

  • Are 22 to 65 years old
  • Have been diagnosed with of bipolar disorder,
  • And are currently in a depressed state
