Bipolar disorder is also known as “bipolar disorder” in medical science, which is a kind of mood disorder and mainly refers to a disease in which manic and depressive episodes occur alternately. The initial judgment can be made through the symptom performance. Manic episodes are often characterized by high emotion, increased verbal activity and high energy, while depressive episodes are often characterized by low mood, loss of pleasure, reduced activity, fatigue and sluggishness. In addition, the bipolar disorder screening scale (MDQ) or the Minnesota Multiple Personality Inventory (MMPI) is commonly used clinically for self-diagnostic testing: 1. Bipolar disorder screening scale: In this table, there are mainly 13 questions containing bipolar disorder, and it takes about 5 minutes to complete MDQ. MDQ is delineated as 7 points, and the higher the score, the more serious bipolar disorder is indicated. The higher the score, the more serious the bipolar disorder and the greater the probability of getting bipolar disorder; 2. Minnesota Multiple Personality Test: This test is currently the most authoritative and meticulous test in the field of psychological assessment, which can detect depression, mania, dysthymia, delusional disorder, schizophrenia and other mental illnesses. If the depression scale D and the mania scale Ma are found to be elevated at the same time, the test indicates bipolar disorder. If the test indicates the possibility of bipolar disorder, you should seek medical attention and regularly use the scale for self-testing to find out the problem and solve it in time. Exercise more, divert your attention and stop thinking about things. When you encounter problems, you should talk to your friends and relatives in time to relieve your pressure and solve problems in time.
