Irish Examiner : declared in Cork scientists link gut bacteria to anxiety disorders

They have discovered that the microbiome, the collective trillions of bacteria within the gastrointestinal tract, regulates fear responses. "We are very excited about this because it is probably one of the first direct links to fear pathways," said Prof Cryan. "We now know that for normal fear responses we need to have appropriate microbes in our gut."Prof Cryan said psychobiotics was a revolutionary new science. It is a very exciting time for us" said Prof Cryan. Researchers at the Science Foundation Ireland-funded APC Microbiome Institute at University College Cork, believe their discovery will lead to novel treatments for a range of anxiety disorders.

Analysis of gut bacteria may guide treatment for IBS patients

They do believe that it should be feasible to screen IBS patients gut bacteria and use that information to help guide treatment in the near future. However, new research could possibly streamline this process to help better predict the most optimal treatment by analyzing patients gut bacteria. Analysis of gut bacteria may guide treatment for IBS patients: StudySuffering from constant diarrhea can be very problematic, as it is not only inconveniencing, but could possibly lead to a decrease in quality of life and even be life threatening in certain situations. Treatment in inflammatory bowel disease patients generally consists of trying one medication and seeing if it works. These well-responding-treatment patients also had a more diverse bacterial community overall in the gut before treatment when compared to those in the study who didn't respond to the treatment.


We may soon be able to control fear by manipulating the mix of bacteria in our gut, new research suggests. It is hoped that scientists will be able to manipulate gut bacteria to control the fear response in humans. "Perhaps most surprising of all is the realisation that gut bacteria influence brain function and behaviour," Dr Clarke said. "What we did not know is that we could target the gut bacteria to control the brain response in a mouse. The role gut bacteria play in our health and wellbeing is increasingly the focus of research.
