First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed trial tested a ketogenic diet (high-fat, low-carb) in 32 people with mild to moderate Alzheimer's disease. Participants followed the diet or a placebo for 26 weeks. Researchers measured changes in cognitive function using a standard test. The goal was to see if the diet is safe and can slow memory decline.
