The main symptoms include ophthalmoplegia, nystagmus, ataxia, impaired consciousness and peripheral neuropathy, etc. The EEG is mostly diffuse slow waves, and the cranial CT shows brain atrophy and ventricular enlargement, which cannot be recovered because the nerve cell damage is irreversible. The symptoms can be improved and prevented from further aggravation by abstaining from alcohol or reducing the amount of alcohol consumed. A small amount of alcohol has a softening effect on the cerebral blood vessels and is good for the body, but long-term heavy drinking not only hurts the brain, but also leads to liver and kidney function damage, induces gastrointestinal cancer and even death. You must develop good habits and drink as little alcohol as possible. Before drinking, you can eat easy-to-digest food to prevent alcohol from stimulating the gastrointestinal tract and stimulating other organs by absorbing alcohol too quickly.
