Research published today in Nature Communications combines brain imaging, behavioral measures and genetics to investigate links between brain structure and mental health. Hu and colleagues developed an analysis framework using UK Biobank data and evaluated its findings in the independent Human Connectome Project cohort.
The analysis identified two reproducible patterns of brain structure: one dominated by cerebellar features and another by cortical features. Genome-wide analyses associated these patterns with 30 and 15 independent significant variants, respectively, without overlapping signals between the two sets.
Follow-up analyses linked the cerebellar pattern to genes involved in chromatin organization and epigenetic regulation, while the cortical pattern implicated neurotransmitter metabolism. The results point to potentially distinct biological contributions to brain–behavior relationships.
These are population-level imaging and genetic findings, not a diagnostic test or treatment. Statistical associations and genetic causal-inference analyses require assumptions and do not establish how an individual person’s mental health will develop. Independent replication supports further investigation but does not demonstrate clinical usefulness.
