[Pharmacological neuroenhancement and brain doping : Chances and risks]

Area of Science:

• Neuroscience
• Pharmacology
• Ethics

Background:

• Pharmacological neuroenhancement involves using psychoactive substances for cognitive improvement in healthy individuals.
• "Brain doping" specifically refers to the illicit use of prescription drugs for cognitive enhancement.
• Substances include psychostimulants, modafinil, antidementia drugs, and antidepressants, often prescribed for conditions like ADHD, Alzheimer's, and depression.

Purpose of the Study:

• To review the efficacy and risks of pharmacological neuroenhancement and "brain doping" in healthy subjects.
• To evaluate specific drug classes for their cognitive-enhancing effects.
• To discuss the ethical and social implications of cognitive enhancement drug use.

Main Methods:

• Literature review of psychoactive substances used for cognitive enhancement.
• Analysis of drug effects on vigilance, concentration, and memory in healthy individuals.
• Examination of safety profiles, side effects, and ethical considerations.

Main Results:

• Psychostimulants and modafinil demonstrate significant improvements in concentration, attentiveness, and vigilance in healthy subjects.
• Antidementia drugs and antidepressants show limited or no significant cognitive enhancement effects in healthy individuals.
• Caffeine is presented as an equally effective and safer alternative for pharmacological neuroenhancement.

Conclusions:

• While certain drugs can enhance cognition, their use by healthy individuals is not recommended due to significant side effects and safety risks.
• "Brain doping" raises substantial ethical and social concerns that necessitate critical discussion and caution.
• The liberalization of cognitive-enhancing drug use should be approached with skepticism, prioritizing safety and ethical considerations.
