According to 2010 data from the Chinese Center for Disease Control and Prevention, China’s serious mental illness has reached more than 16 million people, and about 25% of the city’s people have varying degrees of psychological crisis. This reporter learned from the Inner Mongolia Mental Health Center that the autonomous region currently has 37,000 registered patients with severe mental illness, with schizophrenia being the majority, and the high prevalence group of schizophrenia is dominated by young adults. Psychosis shows some symptoms at an early stage, such as lazy life, emotional indifference, self-talk and self-laughter, suspicious and suspicious, inexplicable feeling of physical discomfort, emotional instability, and unreasonable behavior. Psychiatric patients often believe in hallucinations and delusions caused by symptoms and do things regardless of the consequences. In recent years, reports of psychiatric patients injuring people and destroying things have been in the press. So, why do these conditions occur? Recently, the reporter went into the Inner Mongolia Mental Health Center and interviewed several experts from the hospital about the common symptoms of mental illness and the identification of mental illness. According to the report, most patients with schizophrenia have symptoms of hallucinations and delusions. So what are hallucinations? Yin Zhaohui introduced that hallucinations are a common symptom of perceptual disorders in psychiatric patients, including hallucinations of hearing, vision, smell, taste, touch, and visceral hallucinations, etc. The most common of these is hallucinations, where patients manifest themselves as dazed, listening sideways, and talking out of thin air. They often hear someone talking in their ears or even scolding them, feeling “annoyed” and interfering with their normal life, and they may become angry and scold the “voice”, and some patients do something against their will under the domination of command hallucinations. Hallucinations are not hearing errors, but auditory experiences that are perceived by the patient without sound stimulation. The patient surnamed Wang in our psychiatric intensive care ward, at the beginning of his illness, often heard someone say to him: “You are too lazy, you go hoe! You go cook! You’re an invalid!” Yin Zhaohui said, as a result, he often get up in the middle of the night to hoe and cook. And what is delusion? Yin Zhaohui said that delusion is also a common psychiatric symptom, is based on pathological thinking, the emergence of the self has a personal relationship with the firm beliefs, do not accept the facts and rational correction. Delusions include delusions of victimization, relationship delusions, jealousy delusions, possession experiences, exaggerated delusions, self-criminal delusions, and delusions of physical influence, with delusions of victimization and relationship delusions being the most common. A schizophrenic patient was afraid to drink water because he thought his neighbor was trying to harm him by poisoning the well in his house. He believes that his neighbor is targeting him by throwing water, and that the smoke from his neighbor’s chimney deliberately drifts to his house in order to poison him. He thought that all the people on the street were sent by his neighbors to follow him, so he carried a knife on his body every day for fear of being “killed” until one day, he stabbed a passerby with a knife and said he was “defending himself” and wanted to “strike first. The first day, the knife stabbed a passerby and said it was “self-defense” and to “strike first. Yin Zhaohui said that patients with hallucinations and delusions do not have the ability to test reality, do not recognize the truth of their illusory perceptions, or convinced of false beliefs, do things regardless of the consequences, so that people are caught off guard, which is why most people feel fear, fear, and even avoid the mention of psychiatric patients. Some patients have a slow onset and are often not easily understood as psychiatric patients in the early stages. In fact, psychosis can show some symptoms in the early stages: laziness, emotional indifference, self-talk, suspicion, suspicion, inexplicable physical discomfort, speculum symptoms, emotional instability, and uncharacteristic behavior.
