This page helps you read through the study before you talk to your doctor.
PrevenTRON is a research study. It tests whether treating brain changes before symptoms start can protect memory later. It's for people who feel completely fine right now.
The medication isn't approved yet. The study is finding out if it's safe and if it works.
Alzheimer's-related brain changes often start years before any symptoms show up. A lot has usually already happened by the time of diagnosis.
PrevenTRON tests whether a blood test or brain scan can catch that early signal. It also tests whether treating that signal early changes the outcome.
This works the same way as checking cholesterol before a heart problem happens. PrevenTRON applies that logic to the brain.
Your doctor and the study team will confirm the details. This section gives you a general sense first.
This may be worth a conversation if you're between 60 and 80 years old. It may also apply if you have no Alzheimer's or dementia diagnosis, and you haven't noticed changes in your memory or thinking. You don't need a family history of Alzheimer's to qualify.
The process starts with a conversation. Testing comes next, usually a blood test or brain scan, to check whether you qualify.
Visits are outpatient if you qualify and join. The site determines how often you'd visit and for how long. The study team explains these specifics before you decide anything.
The medication has already gone through earlier testing phases. Researchers are still studying some of its side effects. The study team reviews everything known about these risks with you before you decide.
Blood draws and brain scans carry the same risks as routine medical tests.
You can leave the study at any point, before or after joining. Your regular medical care stays the same either way. You have no obligation at any stage of the process.
