High relapse rate and easy to decline; seriously affect the social function of patients, bringing great harm and heavy burden to patients themselves, their families and society; acute symptoms, especially positive symptoms have been more satisfactory; new generation of antipsychotic drugs also have certain efficacy on negative symptoms and cognitive function; but the prognosis and outcome are still unsatisfactory Currently, the treatment model of mental disorders has been greatly improved from the past The current treatment paradigm for mental disorders has evolved considerably from the past. Prior to the 1960s, treatment for schizophrenia focused on reducing aggression and avoiding victimization and self-injury. By the 1960s and 1970s, patients were able to receive treatment outside the hospital with the help of their families. In the 1980s, doctors tended to focus more on controlling positive symptoms, and in the 1990s, they began to focus on delaying relapses and improving negative and cognitive symptoms. In the 21st century, the traditional treatment paradigm has been replaced by a new “whole course of treatment” and the goal of treatment has evolved to facilitate a successful return to society. The traditional treatment model tends to overemphasize positive symptom control, focus on the acute phase of treatment, and pay insufficient attention to potentially serious somatic adverse effects, resulting in poor patient compliance with traditional treatment. In contrast, the whole-course treatment concept emphasizes the treatment of the patient, taking into account both the acute and maintenance phases, with the aim of reducing relapse and maintaining normal social function, and places greater emphasis on reducing and preventing adverse effects of treatment, thereby improving patient compliance. Thus, the treatment paradigm is now shifting to the principle of equal emphasis on treatment and rehabilitation. Rehabilitation refers to the integrated and coordinated application of medical, social, educational, vocational, and other measures to train and retrain persons with disabilities in order to reduce the consequences of disabling factors, to improve their social functioning as much as possible, to improve their abilities, to restore or maximize their level of functioning, to participate in social life with equal rights, and to fully accomplish normal roles appropriate to their age, gender, social and cultural factors. The goal of psychiatric rehabilitation is: ① Rehabilitation of the disabled person The goals of psychiatric rehabilitation are: (1) rehabilitation; (2) community integration; and (3) quality of life. To restore as much function as possible and return to society, and to restore the highest level of independence psychologically, socially, physically and economically. The significance of schizophrenia rehabilitation: to reduce their relapse rate, to stop their decline, to improve their life and social skills, to reduce the burden on families and society, and to improve the quality of life of the patients themselves and their families. Rehabilitation goals of the traditional rehabilitation system: To reduce the degree of disability. Rehabilitation begins after the onset of disability. The rehabilitation goal of the current rehabilitation system: to reduce functional loss and interrupt the onset of disability. Rehabilitation begins before the onset of disability. Rehabilitation goals of the ideal rehabilitation system: Reduce morbidity and interrupt functional impairment. Rehabilitation begins before the onset of disability.
