Common Brain Network Disruptions Link Schizophrenia and Bipolar Disorder

A study in Frontiers in Psychiatry compared resting-state fMRI from 89 people with schizophrenia, 57 with bipolar I disorder, and 45 healthy controls, finding reduced coordination among distant brain regions in both patient groups—more widespread changes in schizophrenia. This suggests overlapping patterns of brain-network disruption between the two conditions, though not a single wiring fault; results cannot diagnose individuals yet and highlight the need for larger, longitudinal research.
