Julie, not to spill the beans before you listen, but I had the pleasure of hearing this on the 13th. I have been continually impressed as I listen to these researchers, they have such compassion for everyone who is suffering and answer all questions simple and complex with grace. Makes me really feel like they care, gives me hope and not at all what I thought of, when I thought of researchers.
One thing I heard was that the reason they are using the higher age for this A4 study is because when one is studying amyloid buildup the risk of AB increases with age. 1 in 10, 60-65 has amyloid plaque buildup, Sperling said.
In response to a question regarding what can we do if we are outside of study range, she pointed to Alzheimer Prevention registry and the Diane study (? I am not familiar with this) if you are in your early 50's. She also indicated there would be more studies for younger folk next(read us).
All in all, I encourage you to listen to these as they have made me feel connected to research and give me hope, even if I don't participate right now.
