Inflammatory bowel disease (IBD) is a chronic and painful inflammatory-mediated disease of the gastrointestinal system. Recent animal model evidence suggests that cognitive deficits and mood changes experienced by IBD patients are not merely emotional reactions, but result from structural and functional changes in the brain. We used dual-regression analysis of resting-state fMRI data to identify alterations in functional connectivity in IBD patients compared to controls. Connectivity was altered with auditory and pain perception networks, which may help explain behavioural symptoms (hearing loss, pain) commonly experienced by IBD patients.
