The treatment of bipolar disorder should pay attention to "three principles": \x0d\ comprehensive principle, long-term principle and the principle of joint participation of patients and their families. Taking drugs (including mood stabilizers, antipsychotics and antidepressants) is still the main method to treat bipolar disorder. Mood stabilizer is an internationally recognized main therapeutic drug, and it is the main choice from acute stage to consolidation and maintenance stage. \x0d\ Because the symptoms of depression in bipolar disorder are very similar to depression, it is very easy to be missed or misdiagnosed as depression. In addition, bipolar disorder occurs earlier than depression. Many patients with bipolar disorder get sick before 19 years old, but it usually takes 5 to 10 years to be diagnosed, which is very unfavorable for the healthy growth of patients. Therefore, it is necessary to let the public know more about bipolar disorder. Every year, the birthday of Van Gogh, a bipolar disorder patient and painter, is designated as World Bipolar Disorder Day in the world, during which academic exchanges to promote bipolar disorder and standardized treatment are concentrated. \x0d\ Generally speaking, the onset age of bipolar disorder is earlier than that of depressive disorder. Based on the survey data at home and abroad, most patients are between 20 and 30 years old, and onset is more common before the age of 25. Some patients with bipolar disorder have seasonal changes, that is, depressive episodes occur in early winter (10-1month) and manic episodes occur in summer (May-July). \ x0d \ x0d \ Patients with bipolar disorder are easily misdiagnosed as depression. If they are treated as depression, once they go astray, the follow-up treatment will become quite difficult. Paying attention to and identifying hypomania and manic episodes is the key to early intervention of bipolar disorder, and encouraging young patients to actively treat it.
