Scientists at Northern Arizona University are developing a non-invasive blood test that could help detect Alzheimer’s disease before symptoms appear by examining how the brain uses glucose through tiny blood-borne microvesicles. Led by assistant professor Travis Gibbons and supported in part by the Arizona Alzheimer’s Association, the project aims to enable earlier diagnosis and intervention, similar to how doctors manage cardiovascular disease.
New research from the University of California San Diego shows that several common dementia risk factors affect women's cognitive performance more strongly than men's. The findings help explain why women account for nearly two thirds of Alzheimer's cases in the United States.

Researchers from the Institute for Bioengineering of Catalonia and collaborating institutions report that engineered “supramolecular” nanoparticles restored aspects of blood-brain barrier function in Alzheimer’s-model mice, rapidly lowering brain amyloid-β and producing improvements on behavioral and memory tests.
Researchers have linked brain degeneration in stranded bottlenose dolphins to toxins from ocean blooms, mirroring Alzheimer’s disease in humans. The study, focusing on dolphins from Florida’s Indian River Lagoon, highlights the role of climate change and pollution in worsening these blooms. This discovery raises concerns for both marine life and human health.
