Motivation: The mechanisms through which gut microbiota alterations influence changes in brain metabolites in inflammatory bowel disease (IBD) remain poorly understood. Goal(s): To investigate the relationship between levels of brain metabolites, specifically GABA and Glx, and gut microbiome alterations, along with clinical symptoms in IBD patients. Approach: Magnetic resonance spectroscopy (MRS) and 16S rRNA sequencing were employed to assess brain metabolite levels and gut microbiota composition, respectively. Results: Altered brain metabolites observed in IBD may be associated with dysbiosis of gut microbiota. These abnormalities are linked to sleep disturbances and pain experienced by IBD patients. Impact: This study establishes a foundation for understanding the interaction mechanisms between gut microbiota and the central nervous system, offering valuable insights into the neural underpinnings of IBD-associated syndromes.
