CJD not an issue - they use cerebrolysin (in some jurisdictions

) to treat asphyxia related brain damage in newborns, and it has been studied since the 70s if I recall correctly.
I said that it was the only safe drug (IMO) which I should clarify - there are other drugs/'things' that aid/cause neurogenesis. These are (from memory, I may miss one or two):
anti-depressants
exercise
blueberries (yep!)
a challenging mental environment/learning
caloric restriction
meditation
There's a few other drugs and supplements that could be placed on the list that I'm less certain of but have reported benefits (such as psilocybin, ketamine, various BDNF triggers, omega 3 fatty acids) and then also things that are important for brain health but don't cause neurogenesis (vitamin B complexes and choline and many others).
