Why do people get schizophrenia in life? The occurrence of schizophrenia causes serious adverse consequences for patients and their families. Some behaviors of schizophrenia patients often affect the lives of their families and can also cause huge economic losses to society. In fact, it is the lack of understanding of the causes of schizophrenia and the failure to prevent the disease in advance that leads to its occurrence. People with schizophrenia are often called “neurotic, crazy, sick” and other hurtful words, but have you ever thought that maybe this person was not like this, he should be the same as a normal person, what makes a normal person who should have the same emotions as us become like this? 1. Physiological etiology: The dopamine hypothesis is the most widely accepted hypothesis for the cause of schizophrenia. The effect of anti-psychotic drugs on dopamine (DA) neurotransmitters to improve schizophrenia symptoms supports this hypothesis. 2, genetic factors: In the general population, the expected lifetime prevalence of schizophrenia is 0.80%, but the expected lifetime prevalence of relatives of schizophrenia patients is much higher than the general population, the lifetime prevalence of children with schizophrenia in both parents is 46.3%, the lifetime prevalence of children with one parent is 16.7%, and the expected risk of siblings of schizophrenia patients is 10.1%. 3. Mental stimulation: What role do stimulating life events play in the development of the disease? Some scholars believe that stimulating life events trigger the symptoms of people with schizophrenia and make them appear more explicit. Unlike other diseases, schizophrenia is not only physically damaging, but also psychologically devastating, casting a shadow over a person’s otherwise perfect life. Therefore, suffering from schizophrenia should be treated actively and should not be broken. It is like a mirror, if you smile at it, it will smile at you just the same.
