Brief summary

Washington University Early Recognition Center is conducting a research study to examine brain functional connectivity and network patterns in participants with bipolar disorder and schizophrenia.

Detailed description

This study extends the assessment of brain connectivity and function, being conducted in the Human Connectome Project (HCP), to psychiatrically ill populations. The HCP consortium has made significant improvements in MRI instrumentation, data acquisition, preprocessing, and analysis. These improvements are currently providing publicly available data on the structure, function, and connectivity of young adult human (age 22-35) brains at unprecedented spatial resolution, temporal resolution, and accuracy. This study will focus on individuals aged 18-40 years who have a diagnosis of either schizophrenia/schizoaffective disorder or bipolar disorder, or are healthy controls. Additionally, similar to the HCP, the investigator will study the effect of genetics on the patterns of brain connectivity in various psychiatric populations. DNA will be collected non-invasively from saliva. Furthermore, this investigator will study cortisol levels in hair samples as an additional assessment to help characterize brain imagining findings.

Design outcomes

Primary

MeasureTime frameDescription
MRI Brain Imagingwithin one month of study enrollmentThe current project aims to uncover latent, homogenous, connectivity phenotypes using neuroimaging tools, which are free from the limitations of traditional diagnostic boundaries, and which correlate with clinical characteristics. The investigator will use resting state functional connectivity MRI (rs-fcMRI), diffusion MRI (dMRI) and tract-based spatial statistics (TBSS) to identify brain signatures that cut across schizophrenia (SZ) and bipolar (BP).

Secondary

MeasureTime frameDescription
DNA testing through salivawithin one month of study enrollmentSaliva samples will be collected from participants for DNA extraction and the development of lymphoblastoid cell lines. DNA is used for research purposes only, for studies assessing brain connectivity in schizophrenia, bipolar disorder and control subjects.
