Obesity in early adulthood may shape long-term brain health, new research shows.

Researchers at Concordia University have discovered a key brain-marker linking Coronary Artery Disease (CAD) to cognitive decline. Using MRI scans and a novel 12-metric model, they found that older adults with CAD show widespread changes in brain white-matter—particularly in regions fed by the middle and anterior cerebral arteries. These alterations reflect reduced myelin integrity, which correlates with slower processing speed—even when overall cognitive scores are still normal. The findings suggest that myelin-loss may serve as an early biomarker for brain health risks in cardiovascular disease, opening pathways for preventive interventions.

Researchers at the University of Gothenburg have discovered that milk from grey seals in the Atlantic Ocean may be more potent than breast milk. An analysis of seal milk found approximately 33 per cent more sugar molecules than in breast milk. Many of these sugars are unique and may pave the way for even better infant formula for babies.   

Researchers at the Case Western Reserve School of Medicine found that treatment within a week of a brain injury significantly reduced the risk of Alzheimer’s and other cognitive disorders.

A new paper from the University of Kansas overturns the idea that a “risk gene” carried by millions of people worldwide influences production of Type 1 interferon, a workhorse of the immune system.

A new research paper was published in Volume 17, Issue 10 of Aging-US on Oct. 13, 2025, titled “Hospitalization with infections and risk of Dementia: a systematic review and meta-analysis.”
