Psychosis is not as scary as people think, and most psychiatric disorders can be clinically cured through timely, regular, and systematic treatment. Most patients (60-80%) with first-episode schizophrenia can recover completely with systematic and thorough drug treatment. For patients with first-episode mania and depression, systemic treatment is even more effective. Why do many patients have recurrent episodes, which eventually lead to chronicity of the disease, also known as lifelong failure to heal? The key problem lies in the lack of attention to the follow-up treatment after the cure of mental illness. Many psychiatric disorders 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 receive regular follow-up treatment under the guidance of professional psychiatrists and regular review; at the same time, patients’ families raise their awareness, pay close attention to their medication and behavioral and emotional changes, and maximize the recovery of family functions and social skills, many patients can return to society in good condition and resume a normal life. However, if you stop and reduce the medication at will, and listen to the prescriptions, psychosis may become a terrible incurable disease.
