These mechanisms present a natural organization for this article.ДЄ list of drugs in each category and then elaboration on their mechanism of effect would be more elegant than the currently indiscriminate list.

Each of these drugs princibly influences a biological mechanism through which their effects are experienced. We should also strive towards a mechanism based description of the effect of the drug's biological mechanism on cognition.Дrug class -> Description of mechanism of drug class -> Effect of mechanism on cognition and memory.Дrug class -> Drug Class Instances -> Studies on cognitive or memory effects of drug class instancesДЄlthough many drugs belong in multiple categories the majority of these drugs have only one or two dominant mechanisms of actions. Although increased cAMP levels are experienced as 'stimulatory' they have also been implicated in impairment on some memory and learning tasks.ДЄlso, It is not enough to say that 'Dopamine reuptake inhibitors such as methylphenidate increase basal dopamine levels by blocking the reuptake of dopamine'. Decreased cAMP levels hae been implicated in improvement of learning and attentional processes in guanfacine trials. Also some drugs are not monotonously nootropic although caffeine is a adenosine receptor antagonist and hence improves attentional processes, it also impairs certain aspects of cognition via its action as a cyclic adenosine monophosphate (cAMP) phosphodiesterase inhibitor. Mechanisms for choline, piracetam, methylphenidate, guanfacine and dextro-amphetamine are well known and should be mentioned. It is not enough to claim that a substance is nootropic if possible a biological mechanism for performance enhancement should be listed, where available.
