Schizophrenia: Mechanisms and Neurotransmitters

Schizophrenia has existed throughout history, as ancient Greek physicians have described it with different symptoms, but it was not seriously studied until the second half of the nineteenth century, and from the second half of the nineteenth century the classifications related to Schizophrenia developed, which of course was very personal and tasteful. Arnold pick was the first to use the term Dementia praecox to describe the apparently Hebephrenic type of psychiatric disorder. Schizophrenia is a mental disorder characterized by persistent or recurrent forms of psychosis. The main symptoms include hallucinations, delusions, and disordered thinking. Schizophrenia is a chronic and severe brain disease that affects a person's thoughts, feelings, and behaviors, as well as impairing a person's realism. The onset of the disease is between the ages of ۱۶ and ۳۰, but in rare cases it is also seen in childhood. The prevalence is equal in men and women, but the onset age is earlier in men than women. The age of onset in women is two peaks. The age of onset is ۱۰ to ۲۵ years for men and ۲۵ to ۳۵ years for women. The onset of the disease before the age of ۱۰ and after the age of ۶۰ is rare. In cases that start after the age of ۴۵, it is called schizophrenia with a late onset.
