Cognitive enhancement by drugs in health and disease
Open accessAbstract
Attempts to improve cognitive function in patients with brain disorders have become the focus of intensive research efforts. A recent emerging trend is the use of so-called cognitive enhancers by healthy individuals. Here, we consider some of the effects - positive and negative - that current drugs have in neurological conditions and healthy people. We conclude that, to date, experimental and clinical studies have demonstrated relatively modest overall effects, most probably because of substantial variability in response both across and within individuals. We discuss biological factors that might account for such variability and highlight the need to improve testing methods and to extend our understanding of how drugs modulate specific cognitive processes at the systems or network level.

D-amphetamine has been used to enhance cognitive performance in healthy individuals.
“In addition, another application of these drugs is to enhance cognition in healthy individuals who are engaging in certain vocations, referred to as cognitive enhancers (5).”
From Effects of Lisdexamfetamine, a Prodrug of D-Amphetamine, on Locomotion, Spatial Cognitive Processing and Neurochemical Profiles in Rats: A Comparison With Immediate-Release Amphetamine (2022) · cites this paper as [5]
The “Uses of cognitive enhancement” section says that drugs including methylphenidate and modafinil are used by healthy people, including students and military personnel, to maintain or improve performance. The “Effects of genotype on response to drugs” section reports improved performance after a dose of amphetamine in one genotype group, but deterioration in another; it does not identify the drug as D-amphetamine or establish its use for enhancement in healthy people in particular vocations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
