Who could benefit from this research

Could help

Ideal candidates are people diagnosed with bipolar disorder or major depression who have available brain MRI scans and accompanying clinical information, or who are enrolled at contributing research sites.

Less likely to help

People without MRI scans, those with other psychiatric conditions only, or anyone seeking immediate treatment changes should not expect direct personal benefit from this data-focused project.

What this research studies

Researchers are combining existing brain MRIs and clinical information from thousands of people around the world to look for fine-grained differences in brain structure linked to bipolar disorder and major depression. They will run a standardized voxel-wise mapping pipeline (ENIGMA-VBM) that measures anatomy at each small unit (voxel) instead of averaging over large brain regions, allowing inclusion of often-overlooked areas like the cerebellum. The project plans to analyze roughly 3,500 people with bipolar disorder and 8,500 healthy controls and will compare patterns across bipolar disorder and major depression. The goal is to produce reproducible, generalizable brain maps that researchers and clinicians can use to better understand these conditions.

Why it matters

Potential benefit: If successful, this work could reveal brain-based markers that help improve diagnosis and guide more targeted treatment decisions for people with bipolar disorder or major depression.

How similar studies have gone: Previous ENIGMA studies using region-based measures have yielded replicated findings, but applying voxel-wise whole-brain mapping at this scale is a newer and less-tested approach.
