“Fake” Pill Improved Memory and Physical Performance in Just 3 Weeks

An inactive pill produced measurable changes in memory, physical performance and stress among healthy older adults after only three weeks. More surprisingly, some of the strongest results appeared in participants who knew from the beginning that the tablets contained no active treatment.

The findings come from a small randomised controlled trial, not an approved anti-ageing therapy. They suggest that treatment rituals and expectations may influence certain functions, while leaving important questions about durability, mechanisms and clinical usefulness unanswered.
