Researchers compared young and old rats fed a diet with 60% of calories from fat and found that only the older rats showed cognitive decline.Read More

Researchers found that participants who disagreed with the majority view avoided fully expressing their stance and engaged in behaviors that aligned with the majority. This self-silencing reduced cognitive engagement, making them less likely to reflect deeply on the conversation.Read More

Researchers followed 11,745 adults over 14.5 years and found that those who used NSAIDs long-term had a 12% reduced dementia risk.Read More
