Can Alcohol Cause Seizures?

Can alcohol cause seizures? It’s a question that many people ask, especially if they or a loved one suffer from seizures. While there is no definitive answer, there is some evidence that alcohol can trigger seizures in some people.

Seizures are caused by a sudden, brief burst of electrical activity in the brain. Seizures can happen to anyone, but they’re most common in young children and people with certain medical conditions. Alcohol is a central nervous system depressant, which means it slows down the brain’s electrical activity. Drinking too much alcohol can cause seizures.

What is a seizure?

A seizure is a sudden, uncontrolled electrical disturbance in the brain. It can cause changes in your behavior, movements or feelings, and in some cases, loss of consciousness.

There are two main types of seizures: focal and generalized. Focal seizures happen when the abnormal electrical activity is confined to one area of the brain. Generalized seizures are characterized by electrical activity that involves the entire brain.

There are many different types of seizures, and they can vary in severity. Some people only experience a brief period of staring or unresponsiveness, while others may have convulsions and lose consciousness.

In most cases, seizures are caused by an underlying medical condition such as epilepsy. However, it’s also possible to have a seizure without any known cause. This is called an idiopathic seizure.

It’s important to remember that not all seizures are the same, and the treatment will depend on the type of seizure you have. If you think you or someone else is having a seizure, it’s important to seek medical help immediately.

What are the different types of seizures?

There are many different types of seizures, but they can broadly be classified into two main groups:

1. Generalized seizures
These types of seizures affect both sides of the brain and can cause loss of consciousness. There are six main subtypes of generalized seizure, which include:

-Tonic: muscles in the body become stiff
-Atonic: muscles in the body relax
-Clonic: muscles in the body jerk rhythmically
-Myoclonic: brief muscle jerks or twitches
-Absence: staring blankly for a few seconds with no movement at all
-Generalized tonic-clonic (formerly known as grand mal): a combination of tonic and clonic seizure activity, often with a loss of consciousness. These types of seizure are often described as `fit` or `attack`.

2. Focal (partial) seizures

These types of seizure only affect one side of the brain, so consciousness is usually not lost. There are three main subtypes of focal seizure, which include:

-Simple focal seizures: these involve a change in sensation, such as smelling an imaginary odor or experiencing a tingling feeling; sometimes there may be muscle twitching but not enough to cause convulsions
-Complex focal seizures: these involve changes in behavior; for example, someone may stare into space and not respond to anyone around them. Alternatively, they may make repetitive movements, such as hand rubbing, walking in circles or mumbling
-Secondary generalized seizures: these occur when a focal seizure spreads to both sides of the brain; they often cause a loss of consciousness

Alcohol and Seizures

Seizures can be caused by many things, including alcohol. Alcohol can cause seizures by affecting the brain in many ways. Seizures caused by alcohol usually happen when a person drinks too much, too fast. Seizures can also be caused by withdrawal from alcohol.

Can alcohol cause seizures?

It’s well-known that alcohol abuse can cause seizures, but what about social drinking? Can alcohol cause seizures in people who don’t have a history of seizure disorders?

The answer is complicated. Some studies suggest that alcohol may trigger seizures in people who are predisposed to them, but the evidence is far from conclusive. And there are other factors (such as sleep deprivation and stress) that can also increase the risk of seizure activity.

So if you’re wondering whether alcohol can cause seizures, the best answer is: it depends. If you have a seizure disorder, it’s probably best to avoid alcohol altogether. But if you don’t have a history of seizures, moderate drinking is unlikely to trigger one.

According to the Mayo Clinic, alcohol-related seizures generally fall into one of two categories:

Withdrawal seizures: These usually occur in people who drink heavily on a regular basis and then stop or cut back sharply on their alcohol intake. Withdrawal seizures typically occur within six to 48 hours after the last drink, but they can occur up to a week later.

Alcoholic meningitis: This potentially life-threatening condition is characterized by inflammation of the membranes that surround your brain and spinal cord (meninges). Seizures are often one of the first symptoms of alcoholic meningitis. Other symptoms may include confusion, a high fever and severe headache. Alcoholic meningitis is usually caused by bacteria that invade your bloodstream and travel to your brain.

Seizures can occur during alcohol withdrawal for a number of reasons. First, alcohol is a central nervous system depressant, and when it is suddenly removed from the body, the brain is deprived of its normal inhibitory signals. This can lead to over-excitement of the neurons, which can result in seizures. Additionally, alcohol withdrawal can cause changes in electrolyte and blood sugar levels, which can also trigger seizures.


If you have seizures due to alcohol, you will likely need to be treated with medication. There are many different types of seizure medications available, so your doctor will work with you to find the best medication for you. You may also need to make lifestyle changes, such as avoiding alcohol.

There is no specific treatment for alcohol-related seizures. Treatment focuses on stopping the seizure and preventing future seizures. If you have a seizure, you will likely be admitted to the hospital for observation. You may also need to be treated for withdrawal from alcohol.

If you have a seizure, your doctor will likely order a blood test to check your blood alcohol level. If it is high, you may need to be treated for alcohol withdrawal. Treatment for alcohol withdrawal usually involves taking medications to help ease symptoms and prevent seizures. You may also need to be closely monitored during withdrawal to make sure that you do not develop more serious problems such as delirium tremens (DTs).

After you have detoxed from alcohol, your doctor will likely recommend that you stay in treatment for alcoholism. This can involve attending meetings of Alcoholics Anonymous or getting counseling and therapy to help you stay sober. If you have had multiple seizures, your doctor may also prescribe anticonvulsant medications to help prevent future seizures.

If you have had one seizure due to alcohol withdrawal, your chance of having another one is about 50%. If you have had more than one seizure, your chance of having another one is about 70%.
