Nootropics, also referred to as smart drugs, memory enhancers, neuro enhancers, cognitive enhancers, and intelligence enhancers, are drugs, supplements, nutraceuticals and functional foods that improve mental functions such as cognition, memory, intelligence, motivation, attention and concentration.
The definition of nootropic has been blurred by some over the years, at times including substances that are merely cognitive enhancers. However, to be a true nootropic, a substance must have minimal side effects, very little tolerance buildup, enhance a cognitive process and be extremely non-toxic or neuroprotective.
Piracetam was one of the first nootropics created.
Over the years, researchers have improved upon the structure of piracetam. Newer nootropics have been able to more selectively target receptor sub-groups and provide improved effects. As we develop new substances, we discover more about our neurological processes that we did not know before. New receptors and receptor sub-types are found. New binding characteristics are observed and targeted. We advance our knowledge of how we gather, process, interpret, store, and recall information.
