Tiny Brain Region Orchestrates How We Segment and Remember Life Events

Our memories don’t flow like a continuous stream—they’re divided into meaningful events, thanks to a tiny brain region called the locus coeruleus. New research shows this region acts like a “reset button,” activating at event boundaries to signal the hippocampus to store distinct memories.

Dogs Can Sniff Out Parkinson’s Disease

Trained detection dogs can identify Parkinson’s disease (PD) with remarkable accuracy by sniffing skin swabs, according to a new study. In double-blind trials, the dogs achieved up to 80% sensitivity and 98% specificity, even when samples came from patients with other health conditions.

Middle-Age Clues: Blood Biomarkers Signal Alzheimer’s Risk Early

New research shows that signs of Alzheimer’s disease can already be detected in the blood of people as young as their 40s. Finnish scientists found elevated Alzheimer’s-related biomarkers in middle-aged adults, especially among those with maternal history or kidney disease.

Common Sweetener May Raise Stroke Risk by Altering Brain Cells

A common sugar substitute, erythritol, widely used in “sugar-free” and low-carb products, may increase stroke risk by damaging brain blood vessel cells. A new study found that erythritol exposure reduced nitric oxide, increased vessel constrictors, impaired clot-busting abilities, and boosted free radical production in these cells.

Why Women Face Higher Alzheimer’s Risk

Women are nearly twice as likely as men to develop Alzheimer’s disease, a disparity that can’t be fully explained by longevity alone. Researchers are exploring biological differences, focusing on X chromosome-linked genes and hormonal shifts like menopause.

Weekly Injection Could Revolutionize Parkinson’s Treatment

Researchers have developed a long-acting weekly injection that delivers steady doses of levodopa and carbidopa, potentially transforming care for Parkinson’s disease. The biodegradable injectable maintains consistent drug levels, reducing the need for multiple daily pills and improving patient adherence.

Gene Key to MS Immune Regulation Discovered

New research has identified the gene Egr-1 as a critical regulator of immune balance, offering hope for autoimmune disease therapies. In a mouse model of multiple sclerosis, loss of Egr-1 led to reduced regulatory T cell activity and heightened inflammation. T

Study Challenges Link Between Football and Brain Protein Buildup

A new study questions whether playing youth football leads to harmful protein buildup in the brain. Researchers examined 174 donated brains, including former high school and college players, and found no link between contact sports and excess tau protein in a key memory region.

Common Pain Medication Linked to Cognitive Decline Risk

A large U.S. medical records study has found that adults prescribed gabapentin six or more times for chronic low back pain face significantly higher risks of dementia (29%) and mild cognitive impairment (85%) within 10 years. The risks were especially pronounced in younger adults aged 35–64, where rates of cognitive decline more than doubled or tripled compared to those not on the drug.

Cancer Pathway Found to Weaken Brain and Eye Barriers

Researchers have uncovered a surprising connection between a cancer-related signaling pathway and the blood-brain and blood-retina barriers. The study shows that the tumor-suppressing protein p53 weakens the Norrin/Frizzled4 pathway, which is crucial for maintaining these protective barriers.

Brain Pathway Reveals How Pain Feels Emotionally

Pain is more than a physical signal — it also carries emotional weight that shapes our response and memory of discomfort. A new study identifies a group of neurons in the thalamus that directly links pain signals to the brain’s emotional center.

Genes and Brain Wiring Team Up in Alzheimer’s Spread

A new study reveals how genes influence where and how Alzheimer’s-related tau protein spreads in the brain. By combining imaging, gene data, and advanced modeling, researchers uncovered four gene pathways that either amplify or resist tau buildup, depending on brain connectivity.
