1. Can alcohol cause seizures? Why? Alcohol is a central nervous system stimulant, which can affect the activity of many transmitter systems and increase the excitability of the brain, inducing seizures; alcohol can also lower blood calcium, causing seizures; seizures are mostly related to the sudden break of alcohol or a sharp increase or decrease in the amount of alcohol, which may be due to the direct effect of alcohol on brain cells and/or a sharp change in the concentration of alcohol in the blood after the break of alcohol, affecting the normal metabolism of brain cells and inducing brain wave abnormalities, resulting in seizures. 2. What are the characteristics of alcoholic seizures? The majority of seizures caused by alcoholic epilepsy (more than 95%) are generalized seizures, only a few patients (5%) have partial seizures, and some patients show persistent status epilepticus. 1/3 of alcoholic epilepsy is accompanied by delirium and gibberish. The majority (about 80%) of alcoholic seizures appear 7-30 hours after the last drink, with some patients having an onset more than 2 weeks after the last drink, and some alcoholic seizures occurring while drinking. 2/5 patients have only one seizure, and 3/5 patients have more than three seizures, usually within a few hours of each other. About 3% of patients develop persistent status epilepticus. 3. What is the relationship between seizures and alcohol? The frequency and severity of alcoholic seizures are closely related to the amount of alcohol consumed and the length of time it is consumed. As the amount of alcohol consumed increases, the risk of seizures increases. With 50-100 grams of alcohol per day, the likelihood of having a seizure increases 2-3 times compared to non-drinkers; with more than 200 grams of alcohol per day, the likelihood of having a seizure increases 10-20 times. With alcoholic epilepsy, more than half come from alcohol withdrawal, 70% occur at the age of 30-60, and 70% of patients have a history of drinking for more than 10 years. 4. How is alcoholic epilepsy treated? Quitting drinking alcohol is an important measure to prevent and treat alcoholic epilepsy. To prevent withdrawal syndrome, you can gradually quit, not abruptly. Patients with a high number of seizures should be treated with appropriate antiepileptic drugs.
