What are the implications of increasing the amount of human Nerve Growth Factor in the brain? Does it repair and/or creates new neurons within the brain? Idebenone is one such drug that seems to increase the NGF and it's stated benefits are essentially for those who've incurred any kind of brain damage but what kind of benefits does it have for a healthy brain? Does a long term increase in NGF correspond with a long term increase in overall intelligence (as vague and disconnected as that sounds)?
This fascinates me because it would seem to present a way of permanently increasing one's intelligence. Creating more neurons with more connections to one another would seem like a good way to increase intelligence and comprehension. Of course I cannot make the logical jump from increased NGF to increased brain size/neurons without some corroboration. This could very well prove ineffective for healthy users to increase the natural amount of NGF found in the brain, either way though I'd like to know. Thanks.
