What is the difference between nootropics and cognitive enhancers?
The terms nootropic and cognitive enhancer are often used interchangeably, but nootropic actually has a much more restrictive definition. All nootropics are cognitive enhancers, but the opposite is not true.
Cognitive enhancers include any substance that enhance cognitive function, including concentration, learning, memory, and mood. Nootropics must also be neuroprotective and relatively non-toxic.
