Abstract
Cognitive‐enhancing drugs are prescribed to patients with psychiatric disorders, such as attention deficit hyperactivity disorder (ADHD) and Alzheimer's disease, to treat cognitive deficits. This chapter discusses the use of pharmacological agents to improve the cognition of both those with cognitive impairments and of the general population, as well as some of the benefits, risks, and ethical issues associated with the use of cognitive‐enhancing drugs. The chapter also talks about a survey run by the journal Nature, which was prompted by a commentary by the authors of this chapter, that asked readers for their views on the issues surrounding cognitive enhancement. It can be seen that the ethical issues surrounding the use of cognitive‐enhancing drugs are complex and require discussion among different groups. With the development of new drugs and methods of enhancing cognition, such as brain stimulation, the need for further research and discussion is likely to become more pressing.
