Drinking too much to hold up and stand unsteadily is usually considered clinically as a symptom of ataxia caused by excessive alcohol consumption, and such persons need to be observed to avoid alcohol poisoning. Alcohol is basically composed of ethanol, a chemical that has the ability to cross the blood-brain barrier, and if ingested in large quantities, will result in an elevated blood alcohol concentration. When the blood alcohol concentration is high, it enters the brain and inhibits the activity of the cerebral cortex and cerebellar function, which can lead to abnormalities in language function and abnormal walking posture. If the concentration of alcohol in the blood is too high, it may cause paralysis of the central nervous system, which is clinically manifested as a disorder of the central nervous system, and in severe cases, shock may occur. Therefore, it is necessary to observe the drunken member and seek medical treatment in case of emergency.
