Psychiatric disorders are clinically known as mental disorders, and bipolar disorder is one of them, and is one of the six categories of serious mental illnesses prescribed by the National Health Planning Commission. However, there is no clear grade grading of mental disorder diseases, because different diseases have different symptoms, some diseases have more serious effects on the organism with depressive symptoms, some diseases have more serious effects on the organism with manic symptoms, etc. Therefore, it is impossible to make a clear grading of bipolar disorder. Bipolar disorder is a kind of mental disorder with both manic symptoms and depressive symptoms in clinical condition. Bipolar disorder can affect the patient’s life, and if the patient has severe symptoms, he or she may also develop certain paranoid behavior, which may affect his or her life and social security. There is a clear risk assessment scale for mental disorders, with Level 0 showing no dangerous behavior, Level 1 showing only verbal shouting or threats, Level 2 usually showing dangerous behavior in the home or in private spaces, Level 3 showing dangerous behavior in public spaces, Level 4 showing persistent injury and destruction, and Level 5 showing serious physical harm. Bipolar disorder needs to be judged by the severity of the symptoms to determine what level of dangerousness it is currently. The more severe symptoms of bipolar disorder may meet the criteria for a determination of psychiatric disability, and there are different levels of psychiatric disability that need to be assessed on a case-by-case basis. For example, patients with Grade 4 mental disability can usually live on their own but are less capable; patients with Grade 3 mental disability can occasionally communicate with the outside world but need outside support for daily living; patients with Grade 2 mental disability have basic difficulty communicating with others and are unable to maintain daily living on their own; and patients with Grade 1 mental disability are unable to communicate with others and have little ability to live physically or psychologically autonomously. If a patient needs to be rated for mental disability, he or she must contact the local agency to clarify the criteria for review in order to accurately rate a patient with bipolar disorder.
