Oral microbiota: the hidden key to brain health
Keywords:
Dysbiosis, microbiota, neurodegenerationAbstract
The human oral microbiota harbours a great diversity of microorganisms that can interact with each other and with the host to maintain a symbiotic balance. However, various factors can alter its composition, leading to dysbiosis, a process in which potentially pathogenic species proliferate and affect oral health, triggering a variety of oral diseases. In addition, dysbiosis has been linked to the development of neurodegenerative diseases due to proinflammatory mechanisms caused by the colonization of the brain by oral bacteria through various pathways. It is therefore essential to maintain good oral hygiene and monitor oral health.
