Popular weight loss drugs may lower the risk of dementia and stroke. New research published in JAMA Network suggests patients with type two diabetes and obesity who are taking semaglutide or tirzepatide showed a lower risk of developing certain diseases compared to those taking other medications. Researchers analyzed the health developments over seven years in 60-thousand adults and the benefits tilted towards women, patients older than 60, and those with a body mass index of 30 to 40. However, researchers acknowledged more clinical trials are needed to understand the benefits better.
