Schizophrenia is one of the most common and highly disabling serious mental illnesses in the world, and according to domestic and international surveys and statistics, the prevalence rate of the disease is about 1%. According to the world’s 7 billion people, there are about 70 million schizophrenic patients in the world; that is to say, equivalent to the total population of a medium-sized province in China. The clinical manifestations of schizophrenia are colorful and varied, and there is a great deal of variability in symptoms from patient to patient. When parents of intellectual families bring their children for the first time to psychological counseling or outpatient clinics, they always ask what “schizophrenic symptoms” are. In order to clarify this issue, we need to start with the mental activities of human beings. As we all know, since birth, everyone has to carry out breathing, digestion, excretion and other physiological activities, which are relatively simple. At the same time, it is necessary to carry out spiritual activities such as interacting with others, adapting to society, recognizing the world, and transforming the world, which are much more complex than the former. We usually say, “Who knows what is in the heart of the other?” It shows that each person’s spiritual activities are different. But we can abstract from these seemingly different activities the part that is essentially the same, i.e., the general mental (or spiritual) process. This process is extremely similar to the composition and working principle of an electronic computer, which can be divided into an input part, i.e., the part of the eyes, ears, nose, tongue, and body that feels the information; a central processing part, i.e., the part of the brain that analyzes and synthesizes the information, forms the concepts, produces the inner experience, and guides the behavior; and an output part, i.e., the part of the facial expression and various movements and behaviors that are guided by the second part. If there is a malfunction within or between these three parts, it will inevitably produce disordered speech, peculiar facial expressions and outlandish behaviors that cannot be understood and accepted by normal people, so that the whole mental activity and the outside world appear to be extremely incongruous, which is the so-called “schizophrenia” phenomenon. For example, a patient to foreign business trips, the train will feel the station with a kind of cynical eyes on him, through the brain analysis, judgment, and immediately produce a kind of extreme fear of the performance, cloak hair, running wildly, holding the hand of the “weapon”, see the people cut, and cut themselves into serious injuries. From the above analysis, it is clear that both family members and people who have frequent contact with the patient observe only the external manifestations of the patient’s mental activity (part III). Then, what exactly are the external manifestations of schizophrenia? Simply put, it can be summarized in four words: “dull”, “lazy”, “suspicious” and “chaotic”. “Dull”: This kind of performance is more obvious in the early stage of the disease. A person who was originally very lively and cheerful gradually becomes reticent, stares out of the window or at the blackboard during class, and is indifferent to the teacher’s questions and the small movements of his classmates. After class, he walks alone, does not participate in group activities, and alienates his former close friends. After returning home, he ignored his relatives and shut himself up in his room to concentrate on his “homework”, and after a few hours, he did not write a word on his workbook, and his academic performance gradually declined. In the workshop, staring at the processing drawings, let the machine keep turning, a few hours have not processed a part, the ability to work gradually declined. In serious cases, he refused to continue to read and work, and locked himself up in his room all day long, not allowing anyone to go in; he even sat around all day long, not eating or drinking, and did not wash himself. When walking outside, the eyes are dull and the expression is blank. “Lazy”: this performance in the early stage of the disease need to be carefully observed to be able to find. Originally hard-working, neat, disciplined people, gradually become unwilling to get up in the morning, often late, leave early, unwilling to participate in public service labor, do things without a clue, homework is not neat, test papers scribbled. Following the lack of attention to personal hygiene, do not wash their hands to eat, dirty clothes are not willing to change, do not clean up the room, the desk is messy, dirty, need to be helped by family members to take care of. When the disease is serious, do not wash your face, do not gargle, half a year also do not take a bath, a stink, piles of garbage in the room, quilts piled up with dirt, and ultimately become a cloaked hair, pudgy, irregular diet, daily life can not take care of themselves, eating need to be fed, clothing to be worn, lying in bed all day, never get out of bed activities. “Doubt”: i.e. suspicion. At the beginning of the disease, the performance and classmates, colleagues appear particularly sensitive when interacting, teachers do not name criticism, always think it is to criticize him, we comment on the newspaper news or things that happen around, if other people and their own opinions contradict each other, it is thought that the person intentionally against him, look down on him. When other people are talking together, he always likes to go over to them to find out if they are talking about his behavior. Gradually, he thought that other people’s every move was directed at him, that the contents of the television and newspapers were all related to him, and that even when he was walking outside, other people’s waving of hands and spitting were all directed at him. Sometimes he feels that the Public Security Bureau is following him and monitoring him; that there is some kind of instrument controlling him and directing him; sometimes he is convinced that he has great ability; sometimes he has unfounded suspicions that his partner has abnormal relationships with many people of the opposite sex, etc. He even thinks that every move of others is directed against him on television and in newspapers. Even think that the wind and grass outside, birdsong and flowers are all providing some kind of hints to themselves. The general character is absurd and unsystematic, and it is impossible to convince him by laying down facts and reasoning. So when the disease is not in remission, no psychological counseling will help. This suspicion can sometimes be secondary to some kind of hallucination (e.g., hearing a voice that does not exist). “Disorder”: including speech disorder, strange expression and behavioral disorders. Disorganized speech is manifested in the early stage of the disease when recounting certain things, the words do not make sense, can not stick to the theme, so that people have the feeling of not knowing what is going on after listening to the words. When writing an article, the content is loose and puzzling after reading. With the development of the disease, the answer to the question is not what is asked, and when writing an article, there is a lack of connection between sentences, which is like reading a heavenly book after reading. Such as a female patient once wrote: “Birds fly ah, fly to the sky, like can be seen from both sides, I would like to sing a song, like a monk reciting scripture, I’m all thinking about it, I would like to be four-square face, to be a beautiful girl, I want to study an engineer, don’t analyze my brain here, why do you want to be liberated?” …… weird expression manifested in the environment at the time and the extreme incongruity, such as hearing the bad news of loved ones laughed, other people to do a happy event, he bawled and cried. Sometimes he laughs for no reason, and then cries bitterly. Behavioral disorders can be manifested as head and body full of flowers, wearing dazzling clothes in the street dancing; can also be manifested as undressing and pants, naked, chasing the opposite sex in public, crawling on the ground, play the face, picking up dirt on the ground to eat, eating feces and sputum, etc.; in severe cases, the knife can be hacking at the trees, pedestrians, destroying public facilities, and self-inflicted injuries, suicidal behavior. The above four basic manifestations, specific to each patient may all exist, may only appear in 1-2 of them, must not be denied the existence of the disease because of not having all the manifestations.
