## **Core Concept**
Nootropic drugs are a class of medications that are purported to enhance cognitive function, particularly in areas such as memory, creativity, and motivation. The term "nootropic" was coined by Corneliu E. Giurgea in 1972 and is derived from the Greek words "nous" (mind) and "tropos" (direction). These substances are often used to improve mental performance, especially in individuals with cognitive impairments.
