What are antidepressants
Antidepressants are a very necessary thing when a person is on the verge of life and death due to mood disorder. The word “antidepressants” is alarming. We do not know much about mood disorders, especially if we are not interested in it on purpose. Around mental disorders – if not a halo of romanticism and mystery, then frightening stories. There are also those who consider antidepressants to be dangerous drugs that change personality and cause addiction and terrible consequences. Because of this, sometimes those who need treatment refuse it. After all, suddenly all these stories are true?
So what are antidepressants?
Antidepressants – substances that affect the functioning of the central nervous system, and, as the name implies, are mainly used in the treatment of depression. You can buy reliable antidepressants here . These drugs relieve feelings of sadness, apathy, anxiety, anxiety, irritability, tension, increase mental activity, and normalize appetite and sleep. To understand how antidepressants work, you need to understand how the nervous system is organized.
How does the central nervous system work?
The central nervous system (CNS) guides everything. It includes the spinal cord and brain, and it is responsible for simple and complex reflexes – standard responses to any impact. All this works with the help of nerve signals – impulses. The nervous system consists of many nerve cells – neurons. In order for neurons to conduct nerve impulses, they must be connected to a network that will transmit impulses from one cell to another. Imagine children passing the ball to each other in PE class. Children are nerve cells that are connected to the system and the ball is a nerve impulse. But, the hands that children use to pass the ball are synapses, the place of contact.
In synapses, the nerve impulse is transmitted from one cell to another. This happens with the help of neurotransmitters – these are intermediary substances. Accordingly, if there are not enough neurotransmitters, the impulses will pass badly. This means that the work of the whole organism will be disturbed: the nervous system controls everything.
In addition, there is another nuance. Neuromediators are substances of different nature, in particular, among them are noradrenaline, serotonin and dopamine. These substances are hormones. Therefore, in addition to the transmission of nerve impulses, they perform many other functions as hormones. They affect the work of individual organs and systems, the contractility of muscles and blood vessels, and partly – on the mood and inner feelings. And in case of depression, the level of these hormones-neuromediators is often reduced. That’s why patients have such a difficult time: feelings of anxiety, apathy and own worthlessness are caused by lack of serotonin, dopamine and noradrenaline. And since the hormones affect many other body functions, this explains the physical manifestations of depression – weakness, fatigue, unstable appetite. Antidepressants affect the level of these hormones-neuromediators: they block their decay or capture by neurons. This increases their level.
When antidepressants are prescribed
Antidepressants, despite their name, are used not only in the treatment of depression. In case of depression and other mental disorders, antidepressants are also not always used. Scientists still do not know exactly all the features and causes of depression.
