Alcohol addiction disorder, also known as alcohol dependence, is a very common drinking behavior in people’s daily lives, with only 5% of adults not drinking a drop of alcohol in their lifetime, and any level of alcohol consumption is considered a potential population for alcohol dependence, with the exception of those who are completely abstinent. There is a growing number of addiction sufferers worldwide, and in 2011, there was one drug addiction-related death every five minutes in the United States. Addiction is an increasingly common phenomenon, so finding effective and lasting ways to overcome these will be a long-term endeavor. Alcohol addiction tests include: 1. laboratory tests: after drinking alcohol, the patient’s ethanol concentration needs to be checked, in addition, some supportive tests can be done, such as liver function, blood tests, etc.; 2. imaging tests: the patient’s nervous system can be checked by MRI to see if the brain parenchyma has signs of shrinkage, etc.; 3. scale tests: the AUDIT scale, Michigan Drinking Questionnaire and withdrawal symptoms scale can be used etc. to determine the degree of alcohol addiction, usually patients through the AUDIT scale can be self-examination.
