Nootropics
This category covers medicines that promote wakefulness or support attention. They are licensed for specific conditions rather than as general study or productivity aids. The distinction that matters here is between a licensed medicine for a diagnosed condition and a supplement sold for general alertness.
Key points
- These are licensed for specific medical conditions, not as general study or productivity aids.
- Modafinil is licensed for excessive sleepiness and is a controlled medicine in many countries.
- Supplements marketed for memory are a separate class of product with weaker evidence behind them.
Classes and ingredients in this category
- Wakefulness is promoted by modafinil, licensed for excessive sleepiness.
- Attention is supported by atomoxetine, and piracetam is used in specific neurological settings.
Conditions it covers
These medicines are used for narcolepsy and attention deficit hyperactivity disorder. Sleepiness and attention problems have diagnosable causes, and identifying them comes before any medicine.
