Cerebellar Gray Matter Separated Bipolar From Unipolar Depression
A 2026 structural MRI study found that cerebellar gray-matter patterns helped distinguish first-episode bipolar depression from unipolar depression: a model using significant cerebellar lobules reached 76.3% accuracy and AUC 0.779.1 The result is best read as proof-of-concept neuroimaging evidence, not as a scan-based bipolar diagnostic test. Research Highlights Classifier performance was moderate: cerebellar lobules with …
