Is Your Oral Bacteria Influencing Multiple Sclerosis?

High levels of the periodontal bacterium Fusobacterium nucleatum may be associated with more severe disability in people with multiple sclerosis. Researchers analyzed tongue-coating samples and found that MS patients with the highest abundance of this bacteria had significantly worse scores on a standard disability scale.

Tiny Gut Imposters Could Be Driving Multiple Sclerosis

New research reveals that when gut bacteria closely resemble the myelin sheath that protects nerve fibers, the immune system can become confused and attack both — accelerating multiple sclerosis. In mouse experiments, bacteria engineered to mimic myelin triggered faster disease progression by activating aggressive immune cells that infiltrated the nervous system.

Strong Marriages May Rewire Brain–Gut Signals

Strong emotional support within marriage may help protect against obesity by altering how the brain and gut communicate. People in highly supportive marriages showed better control of food cravings, healthier gut metabolism, and higher levels of oxytocin, a hormone linked to bonding and appetite regulation.

No Evidence the Gut Microbiome Causes Autism

Experts reviewing decades of research conclude there is no scientific evidence that the gut microbiome causes autism. They highlight major flaws in observational studies, mouse experiments, and clinical trials, including inadequate sample sizes and contradictory findings.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Toddler Gut Bacteria Linked to Childhood Anxiety and Depression

A new study suggests that a child’s gut microbiome at age 2 may influence their emotional health years later. Researchers found that higher levels of bacteria from the Clostridiales order and Lachnospiraceae family were linked to stronger connectivity across emotion-related brain networks and a higher risk of anxiety and depression symptoms by age 7½.

Gut Fungus Found to Disrupt Brain’s Alcohol Reward Pathway

A new study reveals that an overgrowth of Candida albicans, a common gut fungus, may alter the brain’s dopamine reward circuitry and influence alcohol consumption. Researchers found that as fungal populations increased, they triggered production of inflammatory molecules called PGE2, which crossed into the brain and changed dopamine signaling in the dorsal striatum.

Gut Microbes May Shape Brain and Behavior Through Hidden Mutations

In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior. By sequencing over 5,000 microbial genomes—including 3,500 never before reported—they linked single nucleotide variations (SNVs) in microbes to neurobehavioral traits and plasma metabolites tied to brain function.

Reelin Shows Promise for Healing Both Gut and Depression

A new study reveals that the protein Reelin may hold the key to treating both “leaky gut” and major depressive disorder. Chronic stress lowers Reelin levels in the gut, weakening the intestinal barrier and allowing toxins to trigger inflammation that worsens depression.

Sugary Drinks Linked to Depression Through Gut Microbiome

A new study shows that sugary drinks don’t just affect physical health—they may also raise the risk of depression in women by disrupting the gut microbiome. Researchers found that high consumption of soft drinks was linked to both a greater likelihood of major depressive disorder and more severe symptoms, particularly among women.

Gut Microbes May Hold the Hidden Key to Why We Sleep

A new study shows that bacterial cell wall molecules, specifically peptidoglycan, are present in the brain and fluctuate with sleep cycles. This finding supports a hypothesis that sleep is not solely brain-regulated but arises from the interplay between the body and its microbiome.

Oral Bacteria May Trigger Parkinson’s Disease

Scientists have uncovered a direct link between oral bacteria and Parkinson’s disease. They found that Streptococcus mutans, best known for causing cavities, can settle in the gut and release metabolites that reach the brain.
