What are the molecular mechanisms by which GLP-1RAs provide neuroprotective effects against dementia?
PARTIALLY ADDRESSED
The study demonstrates significant reduction in dementia risk (HR 0.63) with GLP-1RA treatment, but the underlying neuroprotective mechanisms remain unexplained. Understanding these pathways is critical for optimizing therapeutic targeting and developing next-generation neuroprotective agents.
