Today’s era is unarguably an era of science and technology. In the last 100 or even 50 years, the world has progressed dynamically and to some extent unimaginably. If today, a person who died 100 years before from now would wake up, he would die by surprise. No person of that time could have imagined in their wildest dreams that the world would be something like it is today. This is all due to science. Science has helped the world to become this advanced. Every day we see that new additions are being made in science for example everyday more advanced, more efficient and better drugs and medicines are being invented. I believe some could have imagined of the invention of painkillers but I don’t think anyone could’ve thought of drugs that enhance the brain. It seems crazy but it is the reality. Drugs thought to be brain enhancers have been invented. These are known as Nootropics.
Nootropics are smart drugs that are thought to enhance mental functions. These brain supplements are by definition cognitive enhancers. The particular term, “Nootropic” was first used by a Roman doctor in 1972. It is believed that nootropics work by positively increasing the availability of the brain’s supply of neuro-chemicals, by enhancing the supply of oxygen to brain and by nourishing the growth of nerve cells. There are many sub-headings to the word Nootropic. Nootropics are divided into different groups performing different functions. The first category is racetams. Racetams are thought to increase the activity of a receptor by activation of an allosteric site on the protein. Another category of Nootropics is stimulants such as methylphenidate and amphetamines.
Stimulants are also referred to as productivity enhancers. This brain supplement is thought to enhance cognition, improve your concentration level and may also enhance memory. Dopaminergics are also a form of Nootropics that are thought to affect components of the nervous system that use dopamine. They are thought to enhance attention and alertness.
Cholinergics, GABA blockers, Glutamate activators and cAMP are all brain supplements that may improve concentration and enhance memory. Another form of Nootropics is Serotonergics which have various affects on the mood of a person. The mood of a person also has an effect on the brain as if a person is depressed; it can slow down the thinking speed of the brain and thus reduce the efficiency. However, there are anti-stress and anti-depression Nootropics which may counter the negative effects of depression and stress and allow the brain to function properly. These include Beta blockers, lemon balm and passion flower.
An important factor in the proper functioning of the brain is the blood flow and the metabolic functions going on in the brain. Nootropics such as creatine and lipoic acid may improve blood flow and alter the metabolic functions which results in the increase of the efficiency of the brain. Nerves and brain cells are both very important components of the brain. Nootropics such as idebenone and melatonin may stimulate nerve growth and protect the brain cells so the brain can work properly. Some direct hormones such as orexin which may act as a wakefulness promoter are also Nootropics.
One question that rises is that do these Nootropics, which act as a brain supplement, have any negative effects. It is said that they have very few negative effects if any. One example is that stimulants may cause psychosis in some cases but this is very rare. Moreover, these brain enhancers are non-toxic and most of them have been labeled pharmaceutically safe. So these smart drugs are very effective and with little side-effects.
