Dementia rising across Latino populations, multidecade study finds
Dementia rates are climbing sharply across Latin America and the Caribbean, according to a multidecade study from Washington University and Newcastle University — bucking the downward trend seen in the United States and other high-income countries. The findings mark the first direct evidence that some regions of Latin America are moving in the wrong direction. Researchers say the divergence likely reflects gaps in education, healthcare access, and cardiovascular disease management that wealthy nations have made progress addressing.

Emergency doctors are stressed out—and patient irritation plays a significant role
Emergency physicians face mounting burnout, and a new study highlights an underappreciated culprit: difficult interactions with frustrated patients. The findings add nuance to existing research on ER stress, which has largely focused on workload and systemic pressures. As shows like HBO's "The Pitt" bring the human cost of emergency medicine into public view, the data makes clear that the emotional labor of managing patient irritation carries real professional consequences.

Four children with terminal brain cancer saved by new cell therapy
A groundbreaking experimental immunotherapy has successfully treated four children with terminal brain cancer, a disease that historically offers little hope for survival. The therapy works by harnessing the immune system to target and destroy aggressive tumours that conventional treatments cannot defeat. A personalised version of the treatment is now entering broader trials, raising cautious optimism for a disease long considered untreatable.

Game that reduces dementia risk clears amyloid from men’s brains
A cognitive speed-training game has shown the ability to clear amyloid — a protein closely associated with Alzheimer's disease — from the brains of male participants, offering a rare non-pharmaceutical approach to reducing dementia risk. The findings suggest the intervention works through different biological mechanisms in women, pointing to meaningful sex-based differences in how the brain responds to cognitive training. The research adds weight to the case that targeted mental exercise could be a practical, scalable tool in the fight against Alzheimer's.

Body's own cell-to-cell messaging packets studied as the basis for next-generation medicines
Researchers are exploring extracellular vesicles — tiny nanoparticles that cells naturally use to communicate — as the foundation for a new class of medicines. The Blood and Tissue Bank is leading efforts to develop methods for therapeutically manufacturing and deploying these biological packages, which carry rich molecular information between cells. Their subcellular origin and innate compatibility with the body make them a compelling alternative to current gene and cell therapies targeting cancer and other complex diseases.
