APOE4: Should You Join a Prevention Trial? | Jessica Langbaum, PhD
Thinking about joining an Alzheimer's prevention trial as a healthy APOE4 carrier? Here's what it asks of you, and what to ask back.
Jessica Langbaum, PhD, of Banner Alzheimer's Institute has spent her career recruiting people into Alzheimer's prevention studies. Our members asked the questions: would I have to stop my supplements, is placebo fair, what about ARIA with two copies?

WHAT WE COVER
• The three things to weigh before you say yes: time, the results you'll learn, the risk
• How to find a trial, and how long it takes to get in
• What trials usually cover: travel, parking, hotels
• Why a prevention trial can ask you to stop supplements
• What you still get on placebo, and why placebo exists
• ARIA with two copies of APOE4: what she'd check first
• Blood tests like p-tau217, and joining from far away
• Which prevention trials are coming next
• Why two copies is a risk, not a sentence
WANT YOUR QUESTION IN THE NEXT INTERVIEW?
Members can submit questions before future interviews. Not every question fits. Phoenix also helps you build your personal protocol, review your own blood tests and find support from other carriers.

A NOTE ON WHAT THIS IS
I'm Dr. Kevin Tran, a Doctor of Pharmacy. I carry two copies of APOE4.
Education, not medical advice. Every trial is different: the study team and the informed consent are your source for a specific study. APOE4 is a risk factor, not a diagnosis.
