Aniracetam, and most of the Racetams have had a great deal of research done utilizing them to either help treat some form of Cognitive disorder, or help enhance memory in healthy patients.

I've been taking Piracetam, Pramiracetam, L-Theanine, and Alpha-GPC for the past year to help with my memory conditions.

I've dabbled with a few other Nootropics, like Aniracetam, Sulbutiamine, and Centrophenoxine. If you have any questions feel free to ask me, and I'll try to help to the best of my knowledge/abilities.
