There is no mild or severe schizophrenia, only early versus late, i.e. the duration of the episode. As long as schizophrenia is relatively serious, it is one of the most serious mental disorders. The common folk term mild schizophrenia may refer to the time when it is just discovered, when the mental symptoms are not so typical, and when it may have a relatively small impact on the patient’s life. Generally, medical science advocates early detection, early diagnosis, and early treatment. Because schizophrenia is a relatively serious mental disorder that signals a serious impact on a person’s thinking, emotions, and behavior, and episodes are definitely neurological disorders of the brain, and each episode causes serious damage to neurological functions of the brain, a continuous and progressive development, early diagnosis and early treatment must be advocated. There are many symptoms of schizophrenia, which are manifested in thinking symptoms, such as disorder in thinking, disorganized speech, hallucinations, and perceptual disorders, such as the ability to see things that others cannot see and hear sounds that others cannot hear, that is, hallucinations. In addition, patients with schizophrenia also have delusional symptoms, such as suspicion that someone is harming them, feeling that they are very capable, that they can become the president of the country or that they are a millionaire or billionaire, and have many delusional symptoms. There is a lack of motivation and no clear intention for the future. Therefore, once schizophrenia is present, it is a very serious mental disorder and must be treated promptly.
