Thinking is the indirect and generalized reflection of objective things by the human brain. This means that the thinking process is mediated using known knowledge and does not rely on actual objects. At the same time, it reflects the essence of things and the internal connections between things. While normal people’s thinking is subjectively controlled by themselves, some schizophrenic patients feel that their thinking is not under their control, or experience that their thinking no longer belongs to them, but is controlled by an external force. This means that the patient feels that their thinking does not belong to them, that their thinking activity has lost its autonomy, or that they feel controlled by an external force. Examples of such experiences are thought deprivation, thought insertion, and thought diffusion. Thought insertion, thought deprivation, and thought diffusion are common in the early stages of schizophrenia and in the full development of symptoms. What are the causes of abnormal thought control? Thought insertion, thought seizure, and thought spreading are common in the early stages of schizophrenia and during the full development of symptoms. Because the patient does experience this and lacks the ability to recognize their illness, they often feel distressed and cry and complain to their doctor. Pay attention to check to see if there is any abnormal medical history, parental history of heredity, personal emotional problems caused.
