AI-supported scans measuring heart fat could better predict cardiovascular risk

Researchers have shown that AI can analyze routine coronary artery calcium scans to measure fat surrounding the heart—an overlooked but important risk factor—and significantly improve the prediction of future cardiovascular disease. This AI-derived metric works independently of traditional risk factors like cholesterol or blood pressure and is especially useful for identifying hidden risk in patients previously classified as low or intermediate risk. By unlocking more value from existing scans without additional tests, this approach could enable earlier, more precise preventive interventions and reshape how clinicians assess cardiovascular risk.

High-quality plant diets protect against Alzheimer’s, even when started late at life

A large long-term study reveals that simply following a plant-based diet is not enough to protect brain health—what matters most is the quality of the foods consumed. Diets rich in whole, minimally processed plant foods like vegetables, fruits, and legumes were associated with lower dementia risk, while plant-based diets high in processed, sugary, or fried foods actually increased the risk. Importantly, the study also found that improving diet quality later in life can still reduce dementia risk, highlighting that dietary choices remain a powerful and modifiable factor for cognitive health even with aging.

Enriched environments improve stroke recovery and reduce brain inflammation

New research demonstrates that recovery after stroke is not determined by medical treatment alone, but also by the surrounding environment. In animal studies, enriched environments—featuring increased physical activity, social interaction, and sensory stimulation—led to significantly better motor recovery and reduced brain inflammation compared to standard conditions. These environments appeared to protect brain tissue, limit long-term damage, and enhance repair processes through mechanisms like improved microglial response and white matter preservation. The findings suggest that designing more stimulating and supportive rehabilitation settings could play a crucial role in improving long-term outcomes for stroke patients.
