Gut feelings: Is the microbiome linked to our personality?
A new study links the microbiome to personality traits and social behaviors. Those with a larger social network tend to have a more diverse gut microbiome.... Read More...
Probiotic could guard against Parkinson’s
Building on previous research that links gut bacteria to the development of Parkinson's disease, researchers identified a probiotic which prevents the formation of alpha-synuclein.... Read More...
Gut microbes may improve stroke recovery
Microbiota-derived short-chain fatty acids (SCFA) modulate stroke recovery. The effect was mediated by circulating lymphocytes on microglia activation. The study reports SCFAs could be a potential therapeutic to improve post-stroke recovery.... Read More...
Harnessing the microbiome to improve stroke recovery
Short-chain fatty acid supplementation improves stroke recovery in mouse models.... Read More...
Increased use of antibiotics may predispose to Parkinson’s disease
Excessive exposure to certain antibiotics can predispose a person to Parkinson's disease, with a delay of onset of up to 15 years.... Read More...
Fecal transplantation to treat patients with Parkinson’s disease: Hope or hype?
Study reflects on the possible use of fecal microbiome transplants and pre/probiotics to help with the treatment of Parkinson's disease. Findings reveal fecal transplants have not yet been proven to be effective for motor symptoms associated with the condition, and probiotics have only been shown to assist with constipation....

Inflammatory bowel disease appears to impact risk of Parkinson’s disease
Study provides new insights into how the immune system and inflammation play a role in the development and progression of Parkinson's disease.... Read More...
Bacteria in the gut may alter aging process
Transplanting gut microbiota from older mice to younger germ-free mice increased hippocampal neurogenesis and intestinal growth.... Read More...
What do we know about the gut microbiota in Parkinson’s disease?
Researchers propose future gut microbiome studies related to Parkinson's disease should address questions relevant to patient care.... Read More...
Gut instincts: Researchers discover first clues on how gut health influences brain health
Mice bred to be germ-free, and those treated with antibiotics showed a significant reduction in the ability to learn that a threatening danger was no longer present. Sequencing the RNA of microglia in the brains of the animals reveals altered gene expression in the immune cells, which play a role in remodeling how neurons connect during the learning process. Restoring the gut microbiota reverse the learning problems.... Read More...
A possible gut-brain connection to ‘chemo brain’
Manipulating gut bacteria in mice before chemotherapy reduces the mental fog of "chemo brain."... Read More...
