Summary

This study is testing a new tool called the CHRONOS battery to measure how people with Alzheimer's disease perceive time. Researchers want to see if this quick, 10-minute test can identify specific problems with time perception, like judging durations or remembering when events happened. The goal is to find early warning signs and improve care for people with Alzheimer's.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to a simple test that helps doctors spot early signs of Alzheimer's and track how the disease changes a person's sense of time.
What could go wrong
This is a small, early-stage study with only 40 participants, so results may not apply to everyone. The tool is still experimental and not yet proven to improve diagnosis or treatment.
