It is important to identify early signs of schizophrenia so that early detection and treatment can be achieved. If family members observe and analyze the early signs, they can usually find some early signs: Sleep changes: gradually or suddenly becoming difficult to fall asleep, easily waking up or not sleeping deeply, having nightmares throughout the night, or sleeping too much. Emotional changes: Emotional indifference, loss of previous enthusiasm, lack of concern for relatives, lack of proper emotional communication, and alienation from friends. Behavior abnormalities: behavior gradually becomes strange, secretive or incomprehensible, preferring to be alone, talking and laughing to oneself, living a lazy life, dazed and dazed, sleeping in the dark, wandering out, not returning home at night, etc. Sensitive and suspicious: very sensitive to everything, linking some ordinary things around him to him, thinking they are directed at him. For example, if others are talking, they think they are talking about him; if others occasionally look at him, they think it is not good intention. Some even think that the contents of the radio, TV and newspaper are related to him, and they watch what they say and pay attention to others’ every move; some think that someone is trying to harm him and are afraid to drink, eat and sleep. Personality change: the original lively, cheerful and hospitable person becomes silent, sits alone and seems to be thinking about problems, does not interact with others; the person who was always clean and neat becomes unkempt and lazy; the original person who followed the rules becomes often late, early, unexplained absenteeism, sloppy work, etc. Abnormal language expression: not much talk with the topic, simple statements, monotonous content, the content of the conversation lacks the center or in the conversation to say something unrelated to the conversation, so that people can not understand, feel that the conversation is laborious or inexplicable, etc.
