Defective Exosome Production Linked to Alzheimer’s Gene Mutation

New research reveals that a gene mutation tied to Alzheimer’s disease disrupts the production of exosomes, tiny cellular particles essential for communication between brain cells. Cells with a defective SORLA protein produced about 30% fewer exosomes, and those exosomes were up to 50% less effective at supporting cell growth.

Cooler Nights and Brighter Days Boost Sleep in Dementia Patients

A large-scale study shows that indoor environmental changes—such as cooler bedroom temperatures at night and brighter indoor light during the day—can significantly improve sleep in people living with dementia. Researchers analyzed over 26,000 days of data using contactless sensors placed in participants’ homes.

Brain Iron Levels Predict Cognitive Decline Risk

A new study demonstrates that brain iron levels, measured with a special MRI technique, can predict cognitive decline years before symptoms of Alzheimer’s disease appear. Researchers followed 158 cognitively healthy older adults and found that higher iron levels in memory-related regions of the brain were associated with a greater risk of mild cognitive impairment.

Chemotherapy Drug Found to Disrupt Circadian Clock

Nearly half of cancer patients suffer circadian rhythm disruptions during chemotherapy, worsening side effects. A new study using mice shows that paclitaxel, a common breast cancer drug, may disturb the brain’s master clock without directly entering it.

Hidden DNA Loops Linked to Early Spread of Brain Cancer

Scientists have discovered that rogue DNA rings, called extrachromosomal DNA (ecDNA), appear early in glioblastoma and drive its rapid growth and resistance to therapy. By combining patient data, imaging, and computational modeling, researchers found that ecDNA often carries the EGFR cancer gene and its aggressive variants.

Wireless Implant Delivers Drugs Deep in Brain

Researchers have developed a wireless, implantable neural interface that can deliver drugs directly to deep brain regions with precision. The device uses a soft, flexible micro-pump and channel design to ensure controlled, backflow-free infusion without external equipment.

Artificial Sweeteners Tied to Faster Cognitive Decline

A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The effect was particularly strong in people with diabetes and those under 60. Some sweeteners, like aspartame and saccharin, were strongly associated with decline, while tagatose was not.

Air Pollution Linked to Toxic Protein Clumps Driving Lewy Body Dementia

A new study reveals a molecular link between fine particulate air pollution (PM2.5) and Lewy body dementia, a devastating neurodegenerative condition. By combining human epidemiological data and animal experiments, researchers showed that PM2.5 exposure triggers toxic clumps of alpha-synuclein in the brain, similar to those seen in patients.

Dietary Intervention Could Slow Deadly Brain Cancer Growth

A new study reveals that glioblastoma, the most aggressive brain cancer, thrives by using sugar in unique ways that differ from healthy brain cells. While normal brain tissue channels sugar into energy and neurotransmitters, glioblastoma cells divert it into producing DNA and RNA, fueling relentless tumor growth.

3-Minute Brainwave Test Detects Alzheimer’s Years Before Symptoms

A team of researchers has developed a simple three-minute brainwave test called Fastball EEG that can detect early signs of memory impairment linked to Alzheimer’s disease. Unlike traditional memory tests, it is passive and requires no active participation, making it more objective and accessible.

Freezing Brain Molecules Could Halt Deadly Cancer Spread

Scientists have identified a new way to stop glioblastoma — the deadliest form of brain cancer — from spreading by altering its environment rather than targeting the tumor directly. The team showed that cancer cells depend on flexible hyaluronic acid molecules to invade surrounding brain tissue, but when these molecules were "frozen," cells became immobile and dormant.

Alzheimer’s Linked to Epigenomic Breakdown, Not Just Plaques

A new large-scale study shows that Alzheimer’s disease is marked by the erosion of epigenomic control, where brain cells lose the ability to maintain stable gene expression. Using a multi-region atlas of 3.5 million cells, researchers found that vulnerable cells in key memory regions such as the hippocampus suffer breakdowns in nuclear compartmentalization and lose their “epigenomic information.”
