Gut health could reverse brain deterioration, 'game changer' study finds 

UCC researchers Katherine Guzzetta, Dr Thomaz Bastiaanssen, Dr. Marcus Boehme and Professor John Cryan at APC Microbiome Ireland, a world-leading SFI Research Centre, has found that ageing-associated changes in the immune system of old mice were reversed by the transfer of gut microbiota from the young mice. The researchers saw improved behaviour of older mice in several cognitive tests for learning, memory and anxiety. Picture: Clare Keogh

Improving your gut health could turn back age-related brain deterioration including dementia, a “game-changer” scientific study from University College Cork has found.

The human body contains trillions of microbes (bacteria, fungi, parasites, and viruses) which are found in large numbers in the intestines and are collectively known as a microbiome.
