Brain Health

The bacteria in your gut teach your brain’s immune cells how to behave. Here’s the microbiome-microglia connection, minus the hype.

Your brain’s immune cells are listening to your blood sugar. Feed them well and they protect your synapses — spike them daily and the damage compounds quietly.

Your brain’s immune cells work the night shift — pruning synapses and clearing waste. Here’s why cutting sleep short breaks both systems.

The brain-booster industry optimizes neurotransmitters while ignoring the immune cells that actually decide whether your synapses survive.

Your brain has its own immune system, and the cells running it are called microglia. What you eat, how you sleep, and whether you move determines if they protect or destroy.

Traditional flossing and water flossers both clean between teeth — but they trigger very different inflammatory responses in an aging mouth. Here’s what the research says.

New research maps exactly how bacteria from gum disease travel to your brain through your bloodstream and your gut — and what you can do about it.

The systemic failure connecting oral health to neurodegeneration — and why no one is testing for it.

Your dentist and your doctor are operating in silos — and the gap between them could be affecting your brain health.

The practical, research-backed toolkit for protecting your brain through oral health — from probiotics to water flossers to what your dentist isn’t telling you.

The bacteria in your mouth may be influencing your brain health — here’s the science behind the oral-brain connection.

How sleeping with your mouth open fuels brain inflammation through the oral-gut-brain axis.
