Sniff your way to better memory? new trial tests smell training for Alzheimer's risk

This study tests whether a simple smell training program can improve memory, thinking, and daily function in people with mild cognitive impairment (MCI), a condition that often precedes Alzheimer's disease. Thirty participants will either do smell exercises or visual memory exercises at home for 10 minutes a day over 3 months. Researchers will measure changes in smell ability, cognitive tests, and everyday activities to see if this approach could be a helpful early intervention.
