This research study is testing whether a smell test called the AROMHA Brain Health Test can detect early signs of brain diseases like Alzheimer's. Researchers believe that changes in our ability to smell might be an early warning sign before memory problems develop. By having participants complete this 45-minute smell test, the study aims to see if smell testing could become a simple, affordable way to identify people at risk.
Many people show early warning signs of memory and brain problems years before they get diagnosed. If doctors could find a simple, noninvasive test that catches these problems early, they might be able to help people sooner. This study explores whether smell testing could be that early warning tool.

You will complete one visit lasting about 45 minutes where you'll peel and sniff specially labeled smell cards and answer questions about what you smell using a web-based app on a computer or tablet. You'll be tested on how well you can detect smell intensity, identify different smells, tell similar smells apart, and remember smells. You won't receive your individual test results, but your participation will help researchers understand whether smell testing could predict future brain health problems.
