This would be amazing if true, but the lack of randomization makes me nervous. What if, like, patients who are about to get Alzheimer's are less aggressive about asking their doctor for semaglutide (which has been in shortage for a while), and that explains the trial results?
Alzheimer (the regular one, not the early onset) is a progressive condition usually not detected early. Moreover, keep in mind it is possible we understand less about Alzheimer than we thought, from the very start
