Cognitive enhancers, also known as nootropics, are substances that aim to improve mental functions such as memory, attention, and creativity. These can include prescription medications like Adderall and Ritalin, which are often used to treat conditions like ADHD, as well as over-the-counter supplements like ginkgo biloba and omega-3 fatty acids. While some people report benefits from using cognitive enhancers, their effectiveness can vary widely among individuals. Additionally, the long-term safety and ethical implications of using these substances for cognitive enhancement are still subjects of ongoing research and debate in the medical community.
