It is important to recognize the early symptoms of schizophrenia to allow for early detection and treatment. Acute onset patients are difficult to detect or have no early symptoms at all. Most patients have a slow onset of the disease with no obvious cause, and the following early psychiatric symptoms can be observed and analyzed: Sleep changes: Gradual or sudden difficulty falling asleep, waking up easily or not sleeping deeply, having nightmares throughout the night, or sleeping excessively. Emotional changes: emotions become indifferent, lose previous enthusiasm, do not care about relatives, lack of proper emotional communication, distant from friends, not interested in surrounding things, or lose temper over the slightest thing, inexplicably sad and in tears or elated, etc. Abnormal behavior: behavior gradually becomes strange, secretive or incomprehensible, preferring to be alone, uncomfortably chasing the opposite sex, not knowing shame, 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 they have bad intentions. Some even think that the contents of the radio, TV and newspapers are related to him, and they watch what people say and pay attention to their every move; some think that someone is trying to harm him and dare not drink, eat or sleep; some think that their lover is unfaithful to them and thus carry out stalking, etc. Personality change: the original lively and cheerful, hospitable people, become silent, sitting alone seems to be thinking about the problem, do not interact with others; always clean and sharp people become unkempt, lazy life, lax discipline, do not focus; the original rules of the people become often late, leave early, unexplained absenteeism, sloppy work, do not care about criticism; the original frugal people, become wasteful, wasteful. The person who was frugal becomes wasteful and wasteful, and is not interested in things that were of great interest. Abnormal language expression: the person does not have many topics to talk with, simple statements, monotonous content, the content of the conversation lacks a center or says something unrelated to the conversation, making it impossible to understand, feeling that the conversation is laborious or inexplicable, or talking to oneself, repeating the same content over and over again, etc.
