Alcohol and seizures: a question and an answer

T

HI
My Father is an aolcoholic and last Sept he was admitted to hospital after a fall when drunk – whilst in hospital he had a fit – understandable he was cold turkey whilst there. He was treated and sent home. Since Dec he has reduced his drinking and now generally consistantly drinks 1 bottle red wine a day – yes this is still too much but about 50% what he used to drink – he reduced gradually and has maintained this intake for a few months now.
What I find strange is that all i can find about these alcohol withdrawl fits relates to 2-3 days without alcohol – Dad had a fit a few mornings ago after a normal day and normal alcohol consumption levels. The hospital saw alcohol in his notes and packed him off home again with some Vitamin B tablets.
How many alcoholics normally get fits whilst they are still drinking? How normal is this? He is eating better these days than he was but still could do with eating more. He borderline underweight and 74 years old – he has been dependant for more years than I can imagine but probably the last 12 years have been the worst. He does not drink in the morning but the first drink in the day is normally 3/4pm and last drink 6/7pm before bed. This one bottle of wine is often enough for him to fall when on his way to bed or even a few hours later I have had to carry him back to bed if he falls in the bathroom. His body just doesnt seem to be able to cope with alcohol any more – less alcohol to get drunk – is this why he is having the fits?
My apologies for long winded questions but the question needed some context to make sense I think. Any I am not delusional about his alcohol intake – I monitor it and he has no other way or place to stash any.

Thank you so much in advance

P.S. the fit was 6.30 am Thursday and now Sat pm he is still very unsteady and his memory is worse than before. What is the normal recovery from these fits?

Dear T,
thank you for writing in to me about your father. There is no one set limit above which alcohol can induce a seizure. The limit varies from person to person. Rum fits (seizures which occur at the height of binging) of course occur when one consumes too much alcohol in too short time. Alcohol withdrawal seizures classically occur 24-48 hours after the last drink (they occur in people who are chronic alcoholics/ people who consume heavy alcohol on a daily basis and who then suddenly stop drinking). Again not every chronic heavy drinker gets alcohol withdrawal seizure if he/she stops drinking suddenly. Usually it is the person who is chronically malnourished and dehydrated who is more predisposed to an alcohol withdrawal seizure in the setting of sudden cessation of drinking. These people as you can well imagine are deficient in multiple vitamins and minerals (commonly the B group of vitamins such as Vitamin B1, B2, B6, folic acid and B12). Their electrolytes are also more likely to be off (meaning they serum sodium, potassium, magnesium is low). They may also have alcoholic liver disease (alcoholic steatosis or fatty liver, alcoholic hepatitis and finally cirrhosis). During their prolonged drinking years they may also fallen down and struck their head. So it is a combination of factors (meaning the overall health status) and not just the sudden cessation of drinking which predisposes some alcoholics to alcohol withdrawal seizures.
Finally over the course of years of heavy drinking, some alcoholics develop epilepsy. The reason for this may be any of the above I have listed. My personal feeling is that these patients likely have underlying epilepsy and alcohol (in excess or sudden cessation after years of drinking) just helps to unmask it.
Now let me answer your last question about time frame of recovery. Again if his pre-existing neurological status is compromised (his memory is already bad after years of drinking, his general medical condition is poor or if he has coexisting medical problems such as chronic lung or liver disease, diabetes or congestive heart failure) his recovery from a convulsion shall be slow as compared to a young person with no pre-existing medical problems.
I hope I have addressed some of your concerns. I wish you both my very best.

Personal Regards,

Seizures associated with alcohol intake

In this post I thought I shall discuss the effects of alcohol on the brain especially with respect to seizures. Many people drink socially , a drink or two after work is not only relaxing but also enjoyable. But who is an alcoholic or rather when does one have a drinking problem? We doctors use the CAGE criteria as a rather simple questionaire to determine if someone has a drinking problem.

“CAGE” where each letter has a question attached to it and the person has to answer yes or no. Let me elaborate a little.

C–stands for “cutting down”–have you ever felt the need to cut down on your drinking?

A–stands for “anger”—have you ever felt angry if someone has questioned your drinking habit?

G–stands for “guilt”—have you ever felt guilty about your drinking?

E– stands for “eyeopener”–have you ever taken a drink first thing in the morning?

If the person answers yes to these questions, he or she may have a drinking problem. What though is the effect of heavy alcohol drinking on the brain? Does it actually kill brain cells (neurons)? Does it lead to dementia? Can too many drinks cause a seizure?

Alcohol contrary to popular beliefs is a CNS depressant and not a stimulant. Alcohol is rather rapidly absorbed through the lining of the stomach and enters the blood stream from where it is carried to the brain. In the brain, it acts on the neurons and initially causes a loss of inhibition. You loosen up, your speech flows more smoothly and soon you become the life of the party. Well as you continue to drink, alcohol then starts depressing the central nervous system (CNS) . People usually fall asleep soon after consuming alcohol.

But let us get back to how chronic alcohol intake affects the CNS especially with respect to seizures.

I shall discuss this one by one.

Alcohol induced seizures

 

 Heavy alcohol consumption can induce seizures. Alcohol induced seizures are of different types. One is what is commonly referred to as “rum fits”. Let me explain with an example. You are out with your friends celebrating a promotion. Your drink for the night is beer. Your normal “limit” is say 4 beers. But hey you are celebrating and so you end up binging. Before you know it you are on your 10th beer of the night. Right as you are having your 11th beer, your eyes roll up and you have a big generalized tonic-clonic convulsion (see my posts on epilepsy on my website http://braindiseases.info) . This kind of seizure which occurs at the height of binging is what has been referred to as a “rum” fit. I guess it was first described with respect to rum. Any of us can have a rum fit if we drink too much alcohol. You do not need to be an epileptic to have a rum fit, though I feel these kinds of seizures associated with alcohol binging are more common in patients who have an underlying seizure tendency. Thus if you are an epileptic you are more likely to have a rum fit if you overindulge in alcohol as regards to someone who does not have a seizure tendency. Hence I always advise my seizure patients to drink alcohol in moderation. You can drink and by all means enjoy your occasional drink but do not overindulge in this pleasure. Know when to say no and walk out of the bar.

Another type of seizure associated with alcohol is what is called “Alcohol Withdrawal Seizure”. Here the seizure occurs in a different scenario. Usually the person is one who is a chronic alcohol drinker, one who is dependent on alcohol and feels uneasy and restless if he does not drink everyday. Let us now assume he suddenly stops drinking for whatever reason. Maybe he runs out of money and cannot buy alcohol. Usually 24 to 48 hours after his last drink, this patient may have a generalized tonic clonic convulsion. As this seizure occurs in the setting of a withdrawal from alcohol, it is called alcohol withdrawal seizure. It is important that heavy and chronic alcohol drinkers keep this is mind and do not suddenly stop drinking. If a person does decide to quit alcohol he should do it under medical supervision.

Now for the third setting in which seizures might occur with alcohol. Again we have a person who is an alcoholic (heavy and chronic alcohol user). Again for some reason he suddenly stops drinking. Uusally after 72 hours, he starts becoming delirious (confused), he has autonomic dysfunction and is tachycardic, sweating profusely, his blood pressure is up. Such a patient is said to be in what we refer to as “delirium tremens” (DT) . Patient who are in DT may have a flurry of seizures one after the other. DT is a life threatening condition and a patient may die if not treated in time. Usually patients are admitted to the intensive care unit of the hospital. We hydrate them aggressively, we give them medications to calm them down. Lorazepam (Ativan) or other benzodiazepines like chordiazepoxide (Librium) are given to prevent seizures and treat acute alcohol withdrawal.

Patients who have had a rum fit, an alcohol withdrawal seizure or even DT do not warrant long term treatment with an antiepileptic drug. These patients do not have epilepsy. If they abstain from drinking in the future it is more than likely that they may never have a seizure again in their lifetime. However there are a few patients whom we feel have a high risk for seizure recurrence, in such patients we may prescribe antiepileptic drug therapy for some time (the duration of the therapy varies depending upon the history, examination findings and the results of investigations like EEG and CT scan or MRI brain)

I have tried to give an overview of the kinds of seizures associated with alcohol intake. Like I stated earlier one need not be an epileptic to have seizures associated with alcohol intake. I try to explain this to my patients as follows. The brain has a threshold for the amount of alcohol it can tolerate. This threshold varies from person to person. If you drink above that threshold, the brain does not like it and one way it reacts is by having a seizure. This “threshold” is lower in patients who have an underlying seizure tendency. In these epileptic patients, a small amount of alcohol may induce a seizure. Also if you mix your drinks or combine alcohol consumption with other recreational drugs like cocaine you are creating the ideal grounds to have a seizure. Certain medicines like antibiotics also lower your seizure threshold and hence should not be used along with alcohol.

Patients with epilepsy should discuss about alcohol consumption with their doctors because at times we doctors do not initiate this discussion of our own. If you have seizures my advise to you would be to drink in moderation and not exceed your limits.
