Do Nootropics Really Boost Brain Function?

Nootropics are a broad range of both natural and artificial compounds though to improve cognitive function. Including everything from caffeine to Adderall and Provigil, they are popular among students and working professionals alike for their reputation in boosting focus, memory and creativity. But do they really work? Different kinds of nootropics have different functions, and affect people differently. For example, although Adderall is known to boost the abilities of low-performing individuals in areas such as word recall and abstract reasoning, it is otherwise known to impair already high-performers. In a study looking at the effects of Adderall in healthy high-performing individuals, researchers found that although those who took the drug felt they experienced improvements in their cognitive abilities, tests measuring these found none (Ilieva: 2012). Demonstrating a clear placebo effect for improved cognitive functioning, it is possible that given the drug’s reputation for improving cognitive abilities in low-performing people, healthy individuals on the drug mistake its physical byproducts, such as an increased heart rate and blood pressure, as evidence for a higher level of functioning. Provigil, also known as modafinil, is another nootropic known to produce varied results on cognitive functioning. Although a singular dose has led to significant improvements in both episodic and working memory of those with remitted depression, among healthy individuals, its effects seem to be minimal (Fernandez: 2015). Moreover, another study has shown that usage of Provigil among healthy juveniles and adolescents may in fact reduce brain plasticity in the long run due to its potential to overrun optimal chemical balances for brain development (Urban: 2014). Despite these varying use-cases however, other nootropics seem to have less risk and seemingly more positive effects across the board. L-theanine, the counterpart for caffeine found in tea, is a good example of this. A systematic review of the […]
