The patient’s mood is always uncontrolled in the “mania” and “depression” between the switch, swing, like a roller coaster ride like high and low, and like sitting on the warp board suddenly up and down, the patient is often in the abnormal manic agitation, or lethargy, or decrepitude, depression. In fact, they are suffering from a form of serious mental disorder —- bipolar disorder, commonly known as “bipolar disorder”. “When I’m hyper, I feel like I’m Apollo, the sun god, and I can shine on the earth; when I’m depressed, I feel like I’m being smothered, like a rat living in a sewer ……” “When I have an attack, my mind is full of negative thoughts, my body is restless, I can’t tell how uncomfortable I feel, like I’m about to explode, and then I have thoughts of dying. This state is like hell, I don’t want to go on like this ……” The above are the personal feelings of two online users who suffer from bipolar disorder when describing their attacks. It is borrowed here just to give readers a preliminary impression of the manifestation of bipolar disorder. What exactly is bipolar disorder? Bipolar disorder is a type of mood disorder that has both manic or hypomanic episodes and depressive episodes. It is a kind of mental disorder characterized by abnormally high or low emotion, usually onset at the age of 15 to 24, and its etiology is still unclear. The clinical symptoms of bipolar disorder are complex, with a variety of episodes and two main manifestations of manic state and depressive state, which can be repeated in the same patient intermittently, or one state can be the main repeated episodes, with periodicity and remission, and the mental activity of the patient is completely normal in the interval, and generally does not show personality deficit. Bipolar disorder is not a rare disease, but our knowledge and understanding of it is still too little. epidemiological survey data in Hong Kong, China and Taiwan in the 1990s showed that the lifetime prevalence of bipolar disorder was 1.6%. Bipolar disorder is a lifelong disease like hypertension and diabetes, and in 1996, the World Health Organization listed bipolar disorder (bipolar disorder) as the sixth most disabling disease. Bipolar disorder patients are in different mood swings in 19% of their lives, the relapse rate is high, almost 90% of patients will relapse in their lives, the suicide rate is high, and eventually 10%-20% of patients die by suicide. What to do with bipolar disorder Early identification and early diagnosis is the key to treating bipolar disorder. Since bipolar patients have high emotion, high energy and good self-perception when they have a mild manic episode, they generally do not actively seek medical treatment; and when they seek medical treatment for depressive episodes, they tend to ignore the previous manic symptoms, so these patients are often missed or misdiagnosed. The complexity and insidiousness of bipolar disorder make it often misdiagnosed as monophasic depression, anxiety disorder, schizophrenia, personality disorder, substance abuse, etc. before it finally gets a definite diagnosis. One-third of the patients with bipolar disorder experience about 10 years from the onset to the final diagnosis, and the average in the United States is 8.8 years. Bipolar disorder mainly adopts comprehensive treatment, including medication, physical therapy, psychosocial intervention and crisis intervention, in order to improve the efficacy, improve treatment compliance, prevent self-injury and suicide, and improve social function. In view of the characteristics of recurrent episodes of bipolar disorder, adequate amount and full course of medication can reduce the acute pain and improve the long-term prognosis. It is clinically advocated that patients should be treated with long-term mood stabilizers, regardless of the manic and depressive episodes phase or the remission phase. On the basis of pharmacological treatment, health education and psychotherapy can improve patients’ awareness of their disease, understand the necessity of pharmacological treatment, and strengthen the cooperation between doctors and patients, thus improving patients’ treatment compliance and achieving better therapeutic effect. Without effective treatment and maintenance therapy, high relapse rate, long-term recurrent episodes cause increasingly frequent disease attacks, shortened normal intervals, rapid cycling, difficulty in treatment, residual symptoms, chronic state, personality changes, and impairment of social functioning, which can seriously affect patients’ families and work and cause various social problems, such as alcoholism, substance abuse, and suicide. Therefore, the concept of long-term treatment and comprehensive treatment needs to be established to prevent relapse of the disease.
