This book takes the reader from basic questions like “What is health?” and “What is a psychiatric disorder?”, into the midst of people’s present mental health and enhancement choices. More and more people receive psychiatric diagnoses and the use of psychopharmacological drugs keeps increasing. Concurrently, media report the popularity of “brain doping” or “study drugs” on campuses as well as at the workplace. This open access book tests the hypothesis of whether mental health and enhancement can be seen as two sides of the same coin: that the demands on cognitive and emotional functioning have been increasing and psychoactive substances are used to meet these demands. Whether the increasing number of diagnoses means that really more people are suffering from psychological problems will be discussed just as whether the media accurately describe “brain doping” as a new and rising trend.
