Semaglutide (Ozempic) has potential therapeutic effects in neurodegenerative disorders through "modulation of neuroinflammation, enhancement of mitochondrial function, and promotion of neurogenesis". It has shown benefits in animal models of Alzheimer's and Parkinson's. So they're not just testing a random drug, but something that could work.

For details, see: https://pubmed.ncbi.nlm.nih.gov/38921025

This diagram shows how Ozempic can produce these results, the various pathways from the GLP-1 receptor to reduce inflammation, protect neurons, and affect mitochondria: https://cdn.ncbi.nlm.nih.gov/pmc/blobs/87c0/11202139/72234dd...

Thank you, I really appreciate it, as I'm not educated in biochem at all.
