Why do GLP-1 agonists improve brain biomarkers but not cognitive scores in neurodegeneration?

OPEN

The abstract reports improvements in hippocampal connections, cerebral glucose metabolism, and fMRI activation without corresponding cognitive score improvements. This mechanistic disconnect undermines the therapeutic rationale and suggests missing links between neurobiological changes and functional outcomes. Gap type: unexplained_observation Source paper: GLP-1 receptor agonists effect on cognitive function in patients with and without type 2 diabetes. (2023, Diabetes & metabolism, PMID:37657738)
