Schizophrenia symptoms include positive symptoms, negative symptoms, and other symptoms. Specifically, moderate schizophrenia is rich in symptoms such as hallucinations, delusions, and thinking problems, as well as negative symptoms such as emotional withdrawal or emotional depression, sluggishness, social withdrawal, and other negative symptoms, as well as sleep problems and self-control problems. Psychiatry emphasizes that self-control is primarily a function of how well the patient understands the illness, whether the patient acknowledges that he or she is ill, and whether he or she accepts treatment. For moderate schizophrenia there may be a willingness to take medication, but sometimes the patient’s self-control is incomplete, such as regular review at the hospital or ongoing medication, but with the doctor’s guidance, the patient can accept his or her situation. Overall, moderate schizophrenia symptoms are more abundant.
