The Benefits of Ozempic Are Multiplying
There’s mounting evidence that GLP-1 drugs have health benefits beyond diabetes and weight loss, for conditions ranging from addiction to Parkinson’s—and scientists are evolving theories of why.
In a UK trial of 200 people with mild Alzheimer’s disease, an older GLP-1 drug called liraglutide appeared to slow shrinking of the parts of the brain that control memory, learning, language, and decisionmaking by as much as 50 percent. Heather Snyder, vice president of medical and scientific relations at the Alzheimer’s Association, says the results are exciting, although larger trials will be needed to confirm this protective effect. Patricia Grigson, a professor of neural and behavioral sciences at Penn State College of Medicine who led the study, says GLP-1 drugs seem to block the signal in the brain that gets released after eating or taking an addictive substance.
