This observational study analyzed electronic health records of about 1.09 million US patients with type 2 diabetes and found that those prescribed semaglutide (a GLP-1 diabetes/weight-loss drug) were substantially less likely to receive a first-time Alzheimer's diagnosis over 3 years than those on other diabetes medications.

-
One of the five patients with AD treated with LDRT experienced a temporary improvement in SNSB-II.
-
