What this course is about
Nootropics are substances or strategies used with the goal of improving mental performance, such as attention, memory, alertness, motivation, or learning. In everyday language, people often use the term to mean supplements or drugs that may help the brain work better. In this course, we will also include non-drug methods like sleep, exercise, and stress control, because they can have major effects on cognition.

Core cognitive functions
How the brain changes performance
Cognition is not one single ability. It is shaped by sleep, stress, mood, nutrition, hormones, neurotransmitters, and the health of brain cells and blood vessels. If one factor is weak, performance can drop even when the rest are fine. That is why a substance may help one person a lot and another person very little.
