Speaking about neuroleptics specifically, they can thin the cerebral cortex with long-term use, lowering the higher nervous functions. The longer a person uses (from 2 months +), the greater this effect.
It should be clarified that psychotropic drugs are very, very different. In a certain situation, even water applied externally is a strong psychotropic agent.
However, on the whole, everything said above by Yuri is true. The only good news is that my profession is not related to the treatment of psychos.
No, not true. At least in the case of antidepressants. A person becomes a vegetable from an incorrectly selected medicine or dosage. Therefore, it is categorically impossible to experiment with psychotropic drugs, and taking it as directed, in case of discomfort, immediately contact your doctor - correct it.
A well-chosen antidepressant is generally more invigorating. Only in the first days after the start of the intake, there may be a slightly square head - chemistry changes, sleep mode - in short, adaptation occurs.
A person risks becoming a vegetable just from untreated depression.
"Vegetables" are made only by preparations with a pronounced sedative effect. This effect is dose-dependent, that is, in small doses of "vegetable" most likely will not be.
Among antidepressants there are drugs, mainly sedative (for example, amitriptyline), but they do not cause this "vegetable" effect.
Antidepressants can only be beneficial, since their effect is to remove a pathological decrease in mood. Why is it important to do this because having depression or anxiety increases the risk of suicide by more than 10 times. But like any drug, antidepressants also have side effects.
If you are prescribed antidepressants, consult your doctor.
To a certain extent - true.
No matter how selective the mechanism of action of psychotropics, they inevitably affect the nervous system as a whole - regardless of the principle of action. Therefore, the physiological characteristics of the entire nervous system change.
In addition, it should be borne in mind that pharmaceuticals do not affect the SENSE of reactions, only trying to control the response of the nervous system to certain signals. Fear never ceases to be fear, psychosis is psychosis, and depression is depression. REASONS for the condition, i.e. the events that cause it do not go away.
Well, and one more thing. A person who has tried psychotropics once very quickly gets the illusion that the pills are helping him. The result can be addiction with all its charms.
And most importantly - I have observed this on various friends of mine. True, this applies not only to pills: a person acquires the conviction that he is really seriously ill. And this can cause a wide variety of deviations: from self-criticism to complete self-justification in anything. "Former psychos", alas, does not exist. Pathopsychology (I mean clinical psychology and psychiatry) of a person CANNOT eliminate the causes of nervous and mental disorders.
