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.

Scientists Identify New Gene Behind Hereditary Vision Loss

Researchers have identified a new genetic cause of hereditary optic atrophy—a condition that leads to gradual vision loss—by discovering a previously unknown mutation in the PPIB gene. This gene helps proteins fold properly and ensures healthy mitochondrial function, both of which are disrupted in affected individuals.

Child Abuse Leaves Lasting Biological Scars on the Brain and DNA

New research reveals that child maltreatment leaves measurable biological “scars” on DNA, altering brain structure and function. Using a genome-wide epigenetic analysis, scientists identified four key methylation sites—ATE1, SERPINB9P1, CHST11, and FOXP1—linked to maltreatment.

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.

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.

Skin Problems Signal Depression and Suicide Risk

New research reveals that mental health patients experiencing their first episode of psychosis are more likely to have skin conditions, and that these patients face significantly higher risks of depression and suicidality. In a study of 481 individuals, those with dermatological symptoms such as rashes or itching were over three times more likely to report suicidal thoughts.

What Happens After a Near-Death Experience?

New research reveals that people who have near-death experiences often undergo profound shifts in perspective, purpose, and priorities, but many struggle to integrate these changes into daily life. In a study of 167 individuals, over half sought counseling or support afterward, and those who received validation and understanding found the help most beneficial.

Genes Linked to Cannabis Use Reveal Ties to Mental Health

Researchers analyzing data from over 130,000 participants have identified specific genes associated with cannabis use and its frequency, revealing strong links to psychiatric, cognitive, and physical health traits. The genes CADM2 and GRM3, already known for roles in brain communication and impulsivity, appear central to how individuals initiate and sustain cannabis use.

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.
