About

The goal of this cross-sectional study is to use diffusion-weighted imaging based tractography (DWT) to assess white matter (WM) pathways in treatment-refractory bipolar disorder (REF-BD) and treatment responsive bipolar disorder (RSP-BD) subjects compared to healthy controls (HCs). This project will include a prospective controlled trial to include 50 subjects with REF-BD, 50 patients RSP-BD and 50 healthy volunteers.

Enrollment: 26 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers
