Recent studies suggest that liraglutide, a GLP-1 receptor agonist used in diabetes and obesity treatment, may also slow cognitive decline in Alzheimer's disease patients. In a clinical trial involving 204 participants, those treated with liraglutide experienced a 50% reduction in brain volume loss and an 18% slower decline in cognitive function compared to a placebo group. Although the primary goal of improving brain metabolism was not met, secondary outcomes indicated significant cognitive benefits. Experts believe that liraglutide may have neuroprotective effects, potentially by reducing inflammation and improving brain cell communication. The findings have sparked interest in the broader application of GLP-1 medications for neurodegenerative diseases, with further trials on semaglutide expected next year. While there is cautious optimism surrounding these drugs, more research is needed to fully understand their impact on Alzheimer's progression.
