Semaglutide was associated with significantly reduced risk for first-time AD diagnosis, most strongly compared with insulin (hazard ratio [HR], 0.33 [95% CI: 0.21 to 0.51]) and most weakly compared with other GLP-1RAs (HR, 0.59 [95% CI: 0.37 to 0.95]). Similar results were seen across obesity status, gender, and age groups.
From my reading it seems to be becoming more and more clear that inflammation is the real culprit behind the overwhelming majority of aging-related illnesses. But insurance will probably not pay for these drugs, because fuck you.
