• "Researchers wrote, "Cannabinoids offer a multi-faceted approach for the treatment of Alzheimer's disease by providing neuroprotection and reducing neuroinflammation, whilst simultaneously supporting the brain's intrinsic repair mechanisms by augmenting neurotrophin expression and enhancing neurogenesis (the formation of new brain cells).""
• "But there's also a number of these proteins or molecules called neurotrophins, and some of them are produced in the brain, such as the brain- derived neurotrophin factor or BDNF, and some of them are produced in the periphery, such as IGF1 or insulin-like growth factor 1 produced in the muscles and other regions of the periphery."
• "And IGF1 can cross the blood-brain barrier, go into the brain, and it seems to be an early point in this molecular cascade or pathway which stimulates the next neurotrophin, BDNF, which stimulates in turn neurogenesis and new connections and so forth."
