I am grateful that genetics may not determine whether one gets AD or not. I did do dna testing and found I am apoe3/4 and hurried over to a forum on that to learn as much as I could.

Now I am looking into this! “[W]e tracked how amyloid-beta is removed from the [central nervous system (CNS)], showing ~50% is removed across the blood-brain barrier to the blood,” he added. This then led to the discovery that looking at the ratio of amyloid-beta 42 and amyloid-beta 40 could identify whether or not somebody was forming amyloid plaques on their brain.


thank you!
