Brain stimulators were not so safe

 Ritalin (Methylphenidate) - one of the most famous "preparations for the brain." It is a psychostimulant substance. It increases the concentration of neurotransmitters of dopamine and norepinephrine in the brain. Usually it is prescribed for people with the syndrome of hyperactivity and attention deficit disorder. It is popular among students due to the ability to effect on the memory. But there is a point: this drug will help people with poor cognitive indicators, but not those who have high indicators initially. In the second group, the drug generally leads to lower rates due to the weakening of short-term memory.

Modafinil allows you to keep the activity. Originally it was intended for the treatment of sleep disorders such as narcolepsy. The drug increases the level of dopamine in the brain, the person becomes more concentrate. But in general, experts do not really understand how it affects the brain. There are some concerns that modafinil prevent the creativity and flexibility of thinking. As ritalin, modafinil does not help people who do not suffer from lack of attention.

The point is that both drugs affect the concentration of neurotransmitters in the brain. Too high concentration of these compounds is also dangerous as low one. The cerebration is most efficiently at the optimum concentration. Therefore, if a person solves tasks without any problems, most likely, the person has normal concentration. And this balance may not be disturbed. The same happens if a person without any particularly outstanding abilities will start to drink pills with handfuls.
