Kava is able to increase dopamine levels in the nucleus accumbens [2] and desmethoxyyangonin likely contributes to this effect. This, along with several other catecholamines, may be responsible for the purported attention-promoting effects of kava.
Nootropics (/ n oʊ. ə ˈ t r oʊ p ɪ k s / noh-ə-TROHP-iks or / n oʊ. ə ˈ t r ɒ p ɪ k s / noh-ə-TROP-iks), [1] colloquially brain supplements, smart drugs and cognitive enhancers, are natural, semisynthetic or synthetic compounds which purportedly improve cognitive functions, such as executive functions, attention or memory.
Yangonin is one of the six major kavalactones found in the kava plant. [1] It has been shown to possess binding affinity for the cannabinoid receptor CB 1 (K i = 0.72 μM), and selectivity vs. the CB 2 receptor (K i >10 μM) where it behaves as an agonist.
Kava or kava kava (Piper methysticum: Latin 'pepper' and Latinized Greek 'intoxicating') is a plant in the pepper family, native to the Pacific Islands. [1] The name kava is from Tongan and Marquesan, meaning 'bitter.’ [1] Other names for kava include ʻawa (), [2] ʻava (), yaqona or yagona (), [3] sakau (), [4] seka (), [5] and malok or malogu (parts of Vanuatu).

Exposure to psychoactive drugs can cause changes to the brain that counteract or augment some of their effects; these changes may be beneficial or harmful. However, there is a significant amount of evidence that the relapse rate of mental disorders negatively corresponds with the length of properly followed treatment regimens (that is, relapse ...
There are many supposed nootropics, most having only small effect sizes in healthy individuals. The most common pharmacological agents in neuroenhancement include modafinil and methylphenidate (Ritalin). Stimulants in general and various dementia treatments [10] or other neurological therapies [11] may affect cognition.
The human brain requires nutrients obtained from the diet to develop and sustain its physical structure and cognitive functions. [1] [3] [4] Additionally, the brain requires caloric energy predominately derived from the primary macronutrients to operate. [1] [4] The three primary macronutrients include carbohydrates, proteins, and fats.
Regular consumers of caffeine, on the other hand, showed only positive effects when it came to memory tasks. An important factor to consider is that there was fairly wide-range daily caffeine consumption previous to the study, and this could have had a significant effect on performance of the task because not everyone is at the same baseline.
