A compound your gut bacteria make from fiber literally changes which genes your brain expresses — and the effect compounds over time.

New research reveals your oral health may predict cognitive decline — through pathways most doctors and dentists never discuss.

The same bacteria behind your gum disease were found in Alzheimer’s brains — and a pharmaceutical company is now developing drugs to block their toxic enzymes.

Your mouth isn’t just where digestion begins — it’s an active signaling hub that talks to your brain through nerves, metabolites, and immune sensors you didn’t know you had.

Your mouth is the starting point of a pathway that reaches your brain — and most people have no idea it exists.

The 3am wake-up isn’t just a cortisol problem — it’s inflammation hijacking your cortisol curve, and the fix starts with what’s driving the inflammation.

Inflammation doesn’t just cause pain — it hijacks your cortisol rhythm and wakes you up at 3am.

Your gut bacteria produce a compound called butyrate that directly affects brain chemistry. Here is how it works and what you can eat to boost it.

A pharmaceutical company is running clinical trials on a drug that blocks toxins from gum disease bacteria found in Alzheimer’s brains — and the implications go far beyond the drug itself.

New evidence suggests gum disease may contribute to Parkinson’s through systemic inflammation and gut-brain axis disruption.

BDNF is the protein that determines whether your brain bounces back or stays stuck. Your gut bacteria control how much you make.

Three pathways connect your gut bacteria to your brain. Understanding the system — not just one piece — is what actually changes your mental health.
