Summary

Dementia Prevention Strategies

A study involving over a million individuals shows targeting cholesterol-lowering drug pathways may lower dementia risk via non-high-density lipoprotein cholesterol (non-HDL-C).
Researchers at the University of Missouri examine the ketogenic diet's cognitive effects, especially for APOE4 carriers.
A McGill University trial finds online brain training can enhance cholinergic function in older adults, improving memory.
Together, these findings suggest dietary and lifestyle interventions may play a crucial role in dementia prevention.

Summary

Vaccine Reduces Dementia

The shingles vaccine is associated with a 50% lower risk of vascular dementia and a 25% lower risk of heart attack or stroke in adults over 50, compared with recipients of a pneumococcal vaccine.
The study involved more than 174,000 patients.
The findings were presented at IDWeek 2025 and suggest that preventing shingles may reduce inflammation contributing to these conditions.
Experts emphasize vaccination, especially for individuals at higher risk.
