What are nootropics?
The term nootropic was first used in 1972 by Dr. Corneliu Giurgea to describe a substance that positively affected the function of the brain. Although nootropics are often referred to as "intelligent drugs", not all these substances are synthesized chemical drugs. Some nootropics are vitamins, minerals or herbs that increase knowledge.
There are at least four proposed ways in which nootropics can increase the function of the brain. The first way in which these substances can act is to change the amount of neurotransmitters available for brain cells or neurons. Notropics most often affect glutamate or acetylcholine levels, two neurotransmitters that are critical of memory and vigilance, among other things. This class of nootropic substances includes ampacines and racetamas, which are expected to improve memory and ability to concentrate even during severe sleep deprivation due to their ability to change the level of neurotransmitters.
The second way of these substances can positively affect cognitivefunction is preVenci or even reversal of neuron damage. Vitamin B1 is an example of this type of nootropic because it seems that it has the ability to help treat damaged neurons and has memory improvement in people with certain types of brain damage. Antioxidants may also fall into this category because of their proposed ability to prevent neuron oxidative damage.
The third way to increase nootropics increases the function of the brain is to increase the brain oxygen supply. This mechanism is assumed that the popular herb accessory Ginkgo Biloba works. One of the mechanisms of the action of this herb is its obvious ability to increase blood flow to the brain, resulting in the supply of more oxygen to the brain. Although clinical studies have provided mixed results on the effect of Ginkgo bilob on the function of the brain, it is still a popular supplement to improve knowledge.
eventually some nootropics and thought about building new nerve SPsOjening in the brain, which would theoretically allow the brain to function more efficiently. It is believed that racetams cause new nervous connections in addition to their function as modulators at the level of neurotransmitters. Some studies suggest that mechanisms without drugs can also increase the nerve connections in the brain, and some examples of these processes include learning a new language, learning an exercise program that requires agility and coordination, and perhaps even crossing or playing video games.
In several areas of the chosen nootropic substances, they showed positive effects on cognitive function in controlled research studies. This includes improved memory, stronger focus and increased alertness without excessive nervousness. In addition, several of these substances have shown promising people with some cognitive disorders such as Alzheimer's disease or brain damage caused by trauma. However, the ability of nootropics actually increases intelligence is the subject of the ongoing debate.
