Key points from article :
New study shows age-related changes to microbiome contribute to cognitive decline in aged rats.
To demonstrate, fecal microbiota transplantation (FMT) from aged to young rats done.
This shifted young rats' microbiome towards that of aged rats.
Young rats then experienced impaired cognition as a result.
FMT increased levels of pro-inflammatory cytokines and oxidative stress in young rats.
Indicates that inflammation, oxidative stress cause gut-related cognitive decline in ageing.
Also of note is the increased presence of advanced glycation end products (AGEs).
Some researchers propose that the accumulation of AGEs is a reason we age.
Study suggests cognitive impairment is the result of the age-related changes to microbiome.
And that this is mediated by chronic inflammation.
FMT is a reasonably low-tech and translatable approach to promote longevity.
