Psychosis is not as terrible as people think, and most psychoses can be clinically cured through timely, regular and systematic treatment. With systematic and thorough medication, 75% of first-episode schizophrenia patients can recover, and the complete cure rate is up to 10% or more. For patients with first-episode mania and depression, systematic treatment is even more effective. Why do many patients have recurrent illnesses that eventually lead to chronicity? It is due to the lack of attention to the follow-up treatment after the cure of mental illness. Many psychiatric diseases have a tendency to relapse, and the random reduction and discontinuation of medication and the irregular and unsystematic follow-up treatment become important factors for relapse. Therefore, if psychiatric patients can continue to take medication under the guidance of a professional psychiatrist to consolidate the efficacy and prevent relapse, regular follow-up treatment, regular review, and at the same time raise the awareness of the patient’s family, pay close attention to the patient’s medication and behavioral and emotional changes, and maximize the recovery of family functions and social skills, many patients can return to society and resume a normal life. However, if you stop and reduce the medication at will, believe in the prescriptions, and do not pay attention to the follow-up treatment, resulting in recurrent episodes of psychosis and chronicity, psychosis may become a terrible incurable disease.
