This talk will provide a primer on the microbiome-gut-brain-axis in relation to mental and brain health. We will delve beneath the hype to understand the evidence underpinning claims about things like ‘gut health’, fermented foods and faecal microbiome transplants for mood disorders. Mechanisms underpinning gut-brain interactions will be covered, as well as recent research into some of the relevant conditions that neuropsychologists might encounter. Key topics in clinical translation of the research will be discussed, including direct-to-consumer microbiome tests, pro/pre/symbiotic interventions, and implications for health behavioural advice.

 

 

Learning objectives:

1. To understand the key mechanisms and evidence underlying the microbiome-gut-brain axis and its relevance to neuropsychological practice.

2. To critically evaluate the current state of research on the microbiome's associations with neurodevelopmental, mental health, and neurodegenerative conditions, including limitations and challenges.

3. To discuss practical considerations for translating microbiome research into clinical applications, including dietary/lifestyle recommendations, probiotics/psychobiotics, and direct-to-consumer testing.

 

 

Level: Intermediate. This talk will provide neuropsychologists with an in-depth overview of the current research and clinical implications of the microbiome-gut-brain axis, suitable for those with some existing knowledge in this area who are looking to expand their understanding and consider practical applications.

 

 

Presenter:  Amy Loughman, PhD

Professor Dr Amy Loughman is a Senior Lecturer at Melbourne School of Psychological Sciences and clinical neuropsychologist. From 2018-2023 Amy led the Microbiome Stream at Deakin’s Food & Mood Centre. Amy’s research in the microbiome has aimed to unravel its potential role across the lifespan from neurodevelopment to neurodegeneration and to improve standards of practice in analytic methodology, reporting and dissemination of research findings.
