Memory loss after drinking is generally a manifestation of acute alcoholism, and can mostly be improved after rest. Memory in normal people is one of the important functions of the temporal lobe of the brain and the cerebral cortex. Memory loss after drinking alcohol is caused by the fact that after drinking alcohol, alcohol is absorbed into the blood through the mucous membrane of the gastrointestinal tract, and after the alcohol content in the blood reaches a certain concentration, it will have an inhibitory effect on the memory center of the cerebral cortex and the temporal lobe, making memory decline or memory loss, which will lead to memory loss. For the period of time when the concentration of alcohol in the blood rises to a certain level, what happens cannot be recalled normally, but through rest and the metabolism of alcohol by the liver and kidneys, the concentration of alcohol in the blood will gradually decrease and memory will gradually recover. Long-term memory loss after drinking can easily cause a decline in brain function, leading to memory loss, unstable walking and slow reaction, etc. Therefore, it is important to drink in moderation to avoid alcohol poisoning, and patients with cardiovascular and cerebrovascular diseases and diabetes should abstain from drinking.
