Eighty-two percent of patients with schizophrenia relapse within 5 years of their first episode and cure, and with each relapse, the condition worsens further and treatment becomes more difficult. Therefore, the number of relapses should be minimized. Common relapse precursors are as follows: 1. Self-awareness is shaken Once a patient who was able to take medication consciously does not admit that he or she is ill, or even refuses to take medication, be on high alert for relapse. 2, sleep disorders sleep is a “barometer” reflecting the psychiatric condition, when the patient appears unexplained insomnia or excessive bed rest during the day, be highly alert to the relapse of the disease. 3, the ability to live reduced patients become lazy life, do not care about personal hygiene, but also become overly sophisticated, busy all day to dress themselves. 4.Decrease in work or study efficiency Decrease in work ability, loose discipline, irresponsibility, or distracted at work or study, it is difficult to focus, performance and efficiency is also much less than before. 5.Social adjustment disorders such as irritability, impulsiveness, unreasonable or sensitive and suspicious, distracted, indifferent, withdrawn, suddenly becoming talkative or overly enthusiastic towards people, etc. 6.Somatic discomfort such as headache, dizziness, weakness, panic, poor appetite, etc., but these complaints are often variable and vague. 7. The appearance of previous manifestations at the onset of the disease manifests as a fragmentary reproduction of symptoms, unlike the symptoms at the onset of the disease, which are typical and fixed. Once one of the above conditions occurs, the medication dose should be adjusted and psychological intervention should be given as soon as possible under the guidance of a physician, or a psychiatric outpatient clinic should be visited to control the relapse in the nascent stage.
