Mild schizophrenia means that the patient meets the diagnosis of schizophrenia, while the patient’s self-awareness and social functioning are preserved relatively intact and basically unaffected. The main manifestations are: 1. Psychotic symptoms, such as hallucinations, hallucinations, relational delusions, and delusions of victimization, and also disorders of speech and behavior, such as preverbal and intermittent speech, or strange and silly behavior, and patients may also experience anxiety, depression, and fear, which may be related to the patient’s hallucinations or delusions. 2. The patient’s self-knowledge is relatively intact, which means that he or she knows that his or her psychotic symptoms are abnormal and wrong, patients often have a certain desire to seek treatment, will take the initiative to seek medical attention, and actively cooperate with doctors for treatment.3. Patients’ social functions are also not seriously impaired, and can cope with normal life, study, work, and socialization, but may be affected, resulting in decreased efficiency.
