Resting-state fMRI patterns that look older than a person’s years were linked with weaker working memory, poorer executive function, and more depressive symptoms. A separate stool-sample analysis tied some of those brain-age differences to specific gut microbes and metabolites.
In a separate group of 344 participants, certain gut microbes and metabolites (including ceramides and 24-hydroxycholesterol) were associated with differences in the BAI.
# What the study measured
# Who was included and what else was tested
# Main findings on cognition and mood
# Gut connections to brain aging
# Biological pathways implicated The study connected brain-age–associated features to processes involved in:
These pathways are mechanistically plausible for affecting connectivity patterns and cognition.
# What this means for people wanting to support cognition
# Practical takeaways
# Next steps for readers and clinicians The study highlights areas to follow in future research: longitudinal imaging to determine directionality, intervention trials targeting gut or metabolic pathways, and replication in diverse populations. For individuals, the findings emphasize that brain-health differences can appear earlier than expected and that multiple physiological systems contribute to cognitive performance.
And how to support cognition at any age.
A massive MRI study found that Alzheimer’s disease, mild cognitive impairment, psychiatric disorders, and addiction are associated with distinct patterns of accelerated brain aging. The strongest effects appeared in Alzheimer’s and mild cognitive impairment, while ADHD and autism showed no significant overall differenc
A study from the University of Oslo in Norway found that MRI scans may be able to identify a key brain change earlier than previously thought.
Researchers analyzed thousands of brain scans to see how different conditions influenced someone’s predictive age difference.
Your brain may have more than one way to stay sharp as the years go by.
Randox Health The average person spends 20 years of their life in poor health. Let that sink in. But what if you could avoid that? While there are plenty of zeitgeisty ‘ solutions’ to better health floating around in the ether right now, many of them don’t come with a guarantee. It goes without saying that we’d go out
