Probiotics and mood: The ‘gut-brain’ axis

Generally safe and palatable, probiotics have garnered significant attention in recent years for their purported role in bi-directional signalling between the brain and the gut. Mood states may alter gut function while gut health may influence mood and brain function. Ng’s team, comprising of researchers from the National University of Singapore and the University of Nottingham, has undertaken a systematic review and meta-analysis of this subject, which found that probiotics can deliver positive benefits for people suffering from depression. In his presentation he reveals the details of the research, what it might mean for the treatment of depression, and the next steps to developing treatments.
