The emerging field of psychobiotics (Part 3)

The emerging field of psychobiotics (Part 3)

  Today in Part 3 of our series on the gut-brain axis, Drs Amy Reichelt and Sarah McKay discuss mind-altering microbes and the emerging field of psychobiotics. The gut microbiome is a key node in the gut-brain axis. Scientists are only just uncovering how microbes in the gut influence physical, brain and even mental health. In 2004, a pivotal… Continue Reading

How does the microbiome influence our health? (Part 2)

  This is the second post in a series exploring the neurobiology of the gut-brain connection published in partnership with neuroscientist Dr Amy Reichelt. Our intestines are home to an ecosystem of trillions of microbes including bacteria, viruses, phages, fungi, protists, and nematodes. Dominant are bacteria from the families Firmicutes and Bacteriodetes. As I talked about in… Continue Reading

  This is the first post in a series exploring the neurobiology of the gut-brain connection published in partnership with neuroscientist Dr Amy Reichelt.

Can you prevent memory loss and brain ageing?

  Here I take a look at some of the evidence linking education and occupation with better cognitive function in older age.   Rich lifetime experiences like higher education or engaging in mentally challenging occupations have a major influence on how you age cognitively. This is because mentally stimulating activities help build cognitive reserve. Cognitive… Continue Reading

Does MEND reverse Alzheimer’s disease?

Does MEND reverse Alzheimer’s disease?

    In June 2016 a team from the Buck Institute of Ageing published the results of a small case series that used a technique called Metabolic Enhancement for NeuroDegeneration (MEND) to treat people with various stages of Alzheimer’s disease. According to the authors of the study, the results are ‘unprecedented‘. But is this description… Continue Reading
