NCT06991816 · ACTIVE NOT RECRUITING
The Brain&Senses Study
This is a 5-year observational study — researchers watch what happens, they do not give any treatment. It is tracking whether losing senses like smell, hearing, or balance speeds up cognitive decline and affects quality of life in people over 60. Specialists will test all three senses at the start and follow participants over time. It is not a drug or intervention trial, so there is nothing proven or approved being tested here.
