Oral Bacteria May Drive Multiple Sclerosis

Scientists have found that people with multiple sclerosis (MS) have a distinctly imbalanced oral microbiome—marked by a loss of beneficial bacteria and a rise in inflammation-linked microbes. Using advanced genetic and metabolic profiling, researchers revealed that saliva from MS patients also had lower levels of hypotaurine, a molecule that supports antioxidant defense and nerve health.

New AI Tool Reveals Genetic Link Between Memory Cells and Alzheimer’s

A new computational tool developed by researchers has uncovered genetic evidence directly linking Alzheimer’s disease to the loss of memory-making neurons, helping to resolve a decades-long mystery in dementia research. The algorithm, called seismic, matches genetic data to individual cell types, outperforming previous methods and highlighting how specific brain cells—not just immune cells—are implicated in Alzheimer’s.

Long-Term Keto Diet May Damage Your Body

A new study reveals that while the ketogenic diet can prevent weight gain, it may cause severe long-term metabolic problems. Researchers found that mice on a long-term keto diet developed fatty liver disease and impaired blood sugar regulation due to stressed pancreatic cells.

First Signs of Multiple Sclerosis Found Years Before Symptoms

Researchers have traced the earliest stages of multiple sclerosis (MS), showing that the immune system begins attacking the brain up to seven years before diagnosis. By analyzing over 5,000 blood proteins, they identified molecular signs of damage to myelin—the protective sheath around nerve fibers—long before symptoms emerge.

Can a Disconnected Brain Be Conscious?

A new study reveals that sleep-like slow-wave brain activity can persist for years in surgically disconnected brain hemispheres of awake epilepsy patients. Using EEG recordings, researchers found that the isolated cortex exhibits patterns similar to deep sleep, anesthesia, or vegetative states—suggesting absent or reduced awareness.

New Alzheimer’s Mutation Weakens Brain’s Immune Defense

A new study has identified a mutation in the TREM2 gene that disrupts the brain’s ability to clear toxic amyloid plaques, increasing Alzheimer’s disease risk. The mutation, called T96K, keeps the TREM2 gene in an overactive state that paradoxically weakens microglial “cleanup” activity, especially in females.

Where You Live Could Shape Your Brain and Dementia Risk

New research shows that neighborhood conditions — from pollution and housing to economic opportunity — may directly affect brain health and dementia risk. Analyzing brain scans and biomarkers from 679 adults, scientists found that people living in areas with higher social and environmental disadvantages showed signs of reduced brain thickness, altered blood flow, and white matter changes.

Pregnancy Hormones Show Promise in Treating Progressive MS

Researchers have identified two forms of estrogen, estradiol and estriol, that may reduce inflammation and protect nerve fibers in progressive multiple sclerosis (MS). Using a virus model of the disease, the study found that both hormones lowered spinal cord inflammation, while estradiol significantly preserved the myelin sheath that protects nerve cells.

Triggered Hypothermia Protects the Brain After Injury

Scientists have discovered a way to induce a hibernation-like state that protects the brain after injury—without using external cooling. By activating a specific population of neurons, researchers created a reversible drop in body temperature that preserved neuron health and improved motor recovery in mice.

Lymphatic Damage Tied to Chemo Brain Fog

New research reveals that chemotherapy may cause “chemo brain” by damaging the brain’s lymphatic system — the network responsible for clearing waste and supporting immune function. Using mouse models and human-engineered tissues, scientists found that common drugs like docetaxel shrink lymphatic vessels and impair drainage, leading to memory deficits and cognitive decline.

Inflammatory Brain Cells Driving Progressive MS Discovered

Researchers have identified a rare type of brain cell that may drive the chronic inflammation and neurodegeneration seen in progressive multiple sclerosis (MS). These cells, called disease-associated radial glia-like (DARG) cells, appear six times more often in patients with progressive MS than in healthy individuals.

Gene Behind Child Brain Disorder Also Tied to Parkinson’s Disease

Scientists have discovered that mutations in the EPG5 gene—known for causing the rare childhood disorder Vici syndrome—also increase the risk of Parkinson’s disease and dementia later in life. The gene plays a crucial role in autophagy, the process by which cells clear out damaged material.
