For those unfamiliar, nootropics are drugs taken to enhance cognitive performance, the most popular of which are generally regarded as safe, nonaddictive, and sustainable.

Pretty much any aspect of cognition you're seeking to target - memory, focus, fatigue, emotional intelligence, social capability, abstract thinking, creativity, etc. there are generally a bunch of drugs hundreds of people attest to being effective, many with impressive scientific research to back them up.
A lot of the drugs are used to treat disorders of cognitive impairment - Alzheimer's, ADHD, etc. which have subsequently been discovered to be just as effective in healthy people.

I've seen some people discuss their usefulness in various mental illnesses, disorders, etc. but for the most part the anecdotal reports of success with these kinds of drugs are from healthy people. I was just hoping to know if anyone here had given them a shot and if they've been of any use!

Drugs I'm particularly interested in hearing about are those which are known to promote production of new neurons and synapses (neurogenic and synaptogenic drugs), as logically (though perhaps simplistically) they sound like they could be of use in TBI and PCS.

All the drugs I've heard of along these lines are fairly new and experimental (names like NSI-189, Dihexa, 7,8-dihydroxyflavone, etc.), though "cerebrolysin" is one I've heard of which is currently on the market... Has anyone tried it?
