Schizophrenia is a common mental disorder of undetermined etiology, mostly starting in young adults, often with disorders of perception, thinking, emotion and behavior in many aspects and uncoordinated mental activities. Changes require consultation with a psychiatrist, and medication is the primary treatment. After active treatment, some patients can improve their symptoms and remain cured or basically cured, while some patients are prone to relapse or have ineffective treatment, and are refractory to schizophrenia. Early detection, early diagnosis and early start of the whole treatment of schizophrenia can improve the cure rate, and attention to relapse prevention and strengthening of rehabilitation can reduce the relapse rate.
