The manifestations of schizophrenia are multifaceted and can have a variety of different manifestations, but each patient’s manifestations are only individual symptoms and not all of them are required. For more information on how to make a diagnosis based on performance, see Disease Diagnosis. Early symptoms of the disease: 1. Thinking and association disorder. The most characteristic symptom of schizophrenia is the lack of coherence and logic in the process of thinking and associating. The patient’s whole conversation or writing content lacks logic, the narrative is not very relevant, cannot clearly express the meaning around the central idea of the conversation, and it is very difficult to talk with him or her, making people feel confused (loose thinking). Lack of connection between the statements, the words are messy (broken thinking). 2, thinking content disorder. Mainly manifested as delusions. Delusion is a pathological distortion of beliefs, such beliefs do not match the objective facts, the level of education, cultural background, and even absurd and bizarre, but the patient is convinced, can not be persuaded, and can not be corrected by personal experience. 3. Hallucinations. Hallucinations are common symptoms of schizophrenia in which the patient perceives the existence of something that does not exist in objective reality. The most common hallucination is hallucinations, where no one is talking around, but the patient hears a voice speaking. Verbal hallucinations are more common, and content of commentary, argumentative, commanding or thinking sounds are hallucinations with characteristic significance, and more persistent verbal hallucinations also have diagnostic value. Other types of hallucinations are visual hallucinations, touch hallucinations, taste hallucinations, smell hallucinations, visceral hallucinations, etc. 4. Emotional disorders. Patients lack of emotional response to the surrounding things, early for the detailed lack of emotion, such as the care and consideration for their relatives (emotional flat), and in severe cases, indifferent to the important matters involving their own interests, the patient does not have the corresponding emotional response to the general people feel annoyed and painful things (emotional indifference). It is also difficult to communicate with the patient emotionally because of the incongruity between the emotions and the surroundings and the unexplained self-smiling. The above symptoms are characteristic symptoms of schizophrenia. 5. Volitional behavior disorder. 6.Self-awareness.
