Schizophrenia is a disease of the brain, and hypertension, stomach problems, etc. are all dysfunctions of the human body, rather than patients “pretending to be crazy”, not “demonic possession”, and not “past life retribution “The definition of schizophrenia is Schizophrenia is defined as a disorder of thought, emotion, and volitional behavior that is incongruent with the environment or even absurd and bizarre, but of which the patient is not aware. Psychiatrists often say that a normal human brain is like a normal working telephone exchange, while a schizophrenic patient’s telephone exchange system is malfunctioning, either delayed or connected to the wrong line, and his or her speech and behavior is confused. Of course, not every patient is “crazy and frenzied”; many are silent and lazy, emotionally indifferent, and avoid social interaction. It is not always the case that the onset of the disorder is due to a strong stimulus; more people have a slow onset, with insidious symptoms and no obvious cause. Schizophrenia is the most serious mental illness, accounting for 80% of patients between the ages of 16-35. One out of every 100 people may have the disease in their lifetime, with over 8 million in China alone. Schizophrenia has a high relapse and disability rate, a long course of illness, and places a heavy financial and psychological burden on families. The causes of schizophrenia are not fully understood, but genetic factors, external stimuli and personality are all known to play a role, especially in people who are withdrawn and introverted, sensitive and fanciful. Schizophrenia differs from simple psychological problems, which are emotionally unstable but still coordinated in speech and behavior, and in which the patient feels distressed and has a desire to seek treatment, and can be cured and not relapse after psychotherapy. Patients with schizophrenia, on the other hand, lack the desire for treatment and must rely on medication for a long time, making it difficult to achieve recovery through psychological counseling or self-regulation.
