Drinking alcohol is damaging to the brain. First of all, alcohol is an absolute stimulant to the brain, and as long as alcohol is in the body it will always stimulate the nerves, thus making the brain tissue overexcited and not getting enough rest. Just like a person who stands forever and is not able to lie down, there will also be a series of clinical reactions such as fatigue, thus causing a decline in the cognitive function of the brain. Secondly, it can also cause damage to other organs, such as the liver and kidneys, gastrointestinal tract, etc. A person’s organism is a cyclical process, the liver has sufficient detoxification. If once you drink the liver bad, it may cause toxic substances to collect in the brain tissue, such as ammonia toxic encephalopathy. Because the liver’s detoxification of ammonia is lost, it allows ammonia to collect in the brain, thus causing a variety of intracranial neurological symptoms.
