The role of gut microbiota in chronic restraint stress-induced cognitive deficits in mice

How gut bacteria relate to thinking problems caused by long-term stress in mice

AI simplified

Abstract

Mice with chronic stress and cognitive deficits showed a significant correlation between the gut bacterium Muricomes and cognitive impairment, with a predictive accuracy of 0.96.

  • led to reduced movement distances and recognition indices in mice with cognitive deficits compared to those without.
  • Five gut bacteria genera were found to be significantly different across control, CRS-NCD, and CRS-CD groups.
  • Muricomes were enriched in mice exhibiting cognitive deficits and were associated with lower cognitive performance.
  • The gut microbiota composition may play a role in the cognitive deficits observed following chronic stress.
