Schizophrenia is a chronic, high-relapse mental illness. The more relapses of schizophrenia there are, the greater the impact on the patient, until finally affecting the patient’s cognitive and social functions. Families should learn about the precursors of schizophrenia relapse, and should actively treat the disease once it has relapsed. There are signs of schizophrenia relapse: 1. Self-knowledge falters Once patients who were able to take their medication consciously and on time do not admit to having the disease, or even refuse to take their medication, they should be highly alert to disease relapse. 2, sleep disorders Sleep is a “barometer” reflecting the psychiatric condition, when the patient has unexplained insomnia or excessive bed rest during the day, be highly alert to the relapse of the disease. Patients become lazy and do not care about personal hygiene, or they become overly sophisticated and busy dressing up all day long. 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 are also greatly reduced. 5.Social adjustment disorder Such as irritable, impulsive, unreasonable or sensitive and suspicious, distracted, indifferent, withdrawn, suddenly become talkative or overly enthusiastic to people, etc. 6.Somatic discomfort Such as headache, dizziness, weakness, panic, poor appetite, etc., but these complaints are often variable and vague. 7. The manifestation of the previous onset of the disease may appear as fragmentary hallucinations, delusions and other mental symptoms, but not as typical and fixed as the symptoms at the onset of the disease. Prevention is better than cure. While it is good to treat relapses at the early stage of relapse, it is better to prevent relapse of schizophrenia if you can avoid factors that can cause relapse in your life, and if you have already had a relapse before, continue to use medication to prevent it, etc.
