Whether a mental disorder requires hospitalization depends on what the specific diagnosis of the mental disorder is and how severe the disorder currently is. If it is one of the six categories of serious mental disorders, such as schizophrenia, bipolar disorder, paranoid psychosis, psychotic disorder due to epilepsy, mental retardation with psychotic disorder, and schizoaffective disorder. If you have one of these six types of disorders, you should be hospitalized. Because these six types of diseases are relatively difficult to treat, and their conditions are prone to fluctuations and relapses, only systematic inpatient treatment can control symptoms better and faster. In addition if it is some mild disease, such as anxiety or adjustment disorder or depressive episode, the severity of the patient’s condition should be assessed at this time. If it is only mild, no medication can be taken, and if it is moderate and relatively the patient is socially intact, hospitalization can be suspended and medication treatment can be adhered to in an outpatient setting. If these types of disorders also reach severe, the patient’s social function is severely impaired and hospitalization is also required. Therefore, the need for hospitalization for mental disorders should be evaluated based on the diagnosis of the disorder suffered by the patient and the severity of the disorder.
