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.
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.
Researchers identify distinct signatures in the gut microbiome that were associated with either healthy and unhealthy aging trajectories.
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.
Researchers identified specific genetic variants and families of gut microbes associated with anxiety-like behavior, including host genes that influence anxiety indirectly.
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.
Researchers have identified a strain of E.coli in the guts of female mice that cause them to neglect their offspring. The study shows a direct link between the microbiome and maternal behavior.
While gut microbes may be associated with an increased risk of Parkinson's disease, gut fungi are not, a new study reports. The study refutes the speculation gut anti-fungal treatments are helpful for Parkinson's patients.
