Abstract

Emerging evidence highlights a critical relationship between gut microbiota and neurocognitive development. Here we explore whether excessive early life consumption of added sugars negatively impacts neurocognitive development via the gut microbiome. Using a rodent model of sugar-sweetened beverage (SSB) consumption during adolescence, we show that excessive early life sugar intake impairs adult hippocampal-dependent memory function while preserving other neurocognitive domains. Adolescent SSB consumption during adolescence also elevates fecal microbial abundance of Parabacteroides, which negatively correlates with memory task performance. Transferred enrichment of Parabacteroides species P. distasonis and P. johnsonii in adolescent rats impairs memory function during adulthood. Hippocampus transcriptome analyses identify gene expression alterations in neurotransmitter synaptic signaling, intracellular kinase signaling, metabolic function, neurodegenerative disease, and dopaminergic synaptic signaling-associated pathways as potential mechanisms linking bacterial alterations with memory impairment. Collectively these results identify a role for microbiota “dysbiosis” in mediating the negative effects of early life unhealthy dietary factors on neurocognitive outcomes.
