Consuming high levels of sugar-sweetened beverages early in life may lead to memory problems during adulthood. Researchers found, compared to rats who consumed only water, those who drank sugar-sweetened beverages had difficulties in memory recall associated with the hippocampus. The study also found a link between specific changes in gut bacteria in rats who drank sugary drinks and impaired brain function. Read More
Both wisdom and loneliness appear to be influenced by microbial diversity within the gut, a new study reports. Read More
Immune cells in the uterus and placenta of stressed pregnant mice were not activated, but researchers found increased levels of inflammation in the developing fetal brain. Additionally, prenatal stress led to reductions in gut microbial strains and functions, especially in those linked to inflammation. Read More
A meta-analysis study reveals alterations in the gut microbiome may trigger gastrointestinal problems associated with Parkinson's disease. Additionally, the gastrointestinal problems may occur years before other Parkinson's symptoms develop. Read More
In mouse models of neurodevelopmental disorders, researchers found social deficits were mediated by microbes in the gut. By contrast, hyperactivity is controlled by genetics. Treatment with a specific microbe helped improve social behavior. Read More
Researchers have identified a genetic link between depression and an increased risk of developing stomach ulcers. Read More
Study reveals a correlation between the composition of the gut microbiome and behavioral and cognitive performance in mice with Alzheimer's related genes. Read More
Researchers identify distinct signatures in the gut microbiome that were associated with either healthy and unhealthy aging trajectories. Read More
Over 60s with poor appetite were found to have less variety of gut bacteria than those with healthier appetites. Additionally, those with good appetites had more microbes associated with diets rich in fruits and vegetables. Read More
Researchers identified specific genetic variants and families of gut microbes associated with anxiety-like behavior, including host genes that influence anxiety indirectly. Read More
Researchers found significant differences in samples from the appendix of people with Parkinson's disease, specifically in microbial composition correlating with higher levels of toxic bile acids. Read More
A new "organ on a chip" system helps researchers uncover how bacteria in the human digestive tract can impact neurological diseases. Read More
