What Causes Alcohol Withdrawal Seizures
Content
Researchers say there are two main reasons people drink – they turn to alcohol to cope with stress, or because of influences from their social circle. When the alcohol level suddenly drops, your brain stays in this keyed up state. Over time, your central nervous system adjusts to having alcohol around all the time.
A first-time “withdrawal” seizure must be evaluated as any first-time seizure, even in alcoholics who claim to have had seizures in the past but for whom no documentation of previous seizures or evaluation is available. Other conditions need to be ruled out by history, physical examination, and diagnostic testing, including electrolytes, glucose, and brain CT scan. There are many potential triggers for someone who is prone to seizures.
Because drinking impacts the brain, it can have an impact on chemicals in the brain that control seizures. This is especially true if you drink heavily because small or moderate amounts of alcohol are not linked to seizure. If you or a loved one has a history of seizures or alcohol withdrawal, learning about the link between drinking and seizures is important. Although there are many benzos available, diazepam , lorazepam , and chlordiazepoxide are the most frequently used. They’re sedatives that work by stimulating gamma-aminobutyric acid , a chemical in the brain that is involved in setting off alcohol withdrawal symptoms. Some patients achieve dramatic results by joining 12-step groups such as Alcoholics Anonymous and Narcotics Anonymous. Other patients benefit from stays in comprehensive treatment facilities, which offer a combination of a 12-step model, cognitive-behavior therapy, and family therapy.
Epilepsy Medication
Benzodiazepines are the most evidence-based treatment for alcohol withdrawal in the ED. Pharmacotherapies that have demonstrated benefit for treatment of alcohol withdrawal in other inpatient and outpatient settings should be evaluated in the ED setting before routine use. Most treatment options may include the administration of long-acting benzodiazepines.
We excluded review articles and case reports, studies published prior to 1980, non-English publications, and non-human studies. In line with our goal of producing this evidence summary expeditiously, we did not publish a review protocol or register this review prior to study initiation.
Patients undergoing preoperative evaluation also should be screened, because alcohol withdrawal can complicate recovery from surgery.29 Elective surgery should be postponed until the dependent patient has not had alcohol for seven to 10 days. Alcohol withdrawal syndrome can be confused with other conditions. Thyrotoxicosis, anticholinergic drug poisoning, and amphetamine or cocaine use can result in signs of increased sympathetic activity and altered mental status. Central nervous system infection or hemorrhage can cause seizures and mental status changes.
- The periaqueductal gray is thought to trigger clonic seizures, whereas the pontine reticular formation is implicated in the generation of the tonic phase of audiogenic seizures .
- For most drinkers, the frequency and amount of alcohol consumption does not impair physical or mental health or the ability to safely carry out daily activities.
- Here at Landmark Recovery, we aim to help as many people as possible overcome addiction and go on to enjoy fulfilling lives.
- Newborn neurons in both the olfactory bulb and DG continuously remodel local neural circuits.
When a person ceases their consumption of alcohol, their CNS becomes overexcited, causing symptoms that have associations with alcohol withdrawal. Luckily, there’s little to fear as long as you pursue recovery options under close medical supervision. As stated earlier, deaths linked to alcohol withdrawal are extremely rare and are almost completely preventable. During delirium tremens, patients are suggestible to many sensory stimuli, particularly to objects seen in dim light. Vestibular disturbances may cause them to believe that the floor is moving, the walls are falling, or the room is rotating. As the delirium progresses, resting tremor of the hand develops, sometimes extending to the head and trunk.
Faqs About Alcohol & Seizures
Within a time window of four to six weeks, adult-born DGCs mature and form the characteristic tri-synaptic circuits connecting the entorhinal cortex to the DG, and the DG to the CA3. These four- to six-week-old neurons show reduced induction threshold and increased LTP amplitude in response to a physiological stimulation . Thus, adult neurogenesis represents an ongoing developmental process during which the nervous system is continuously remodeled. This provides an expanded capacity of plasticity in response to experience . Further studies are needed to evaluate symptom-triggered benzodiazepine protocols in the ED. Pharmacotherapies that have demonstrated benefit for treatment of alcohol withdrawal in other settings need to be evaluated in the ED setting before routine use. This review is limited by the overall poor quality of included studies, most of which were at high/serious risk of bias.
- Tolerance to alcohol develops rapidly; similar amounts cause less intoxication.
- Phenytoin does not have evidence of effectiveness at preventing withdrawal seizures in the ED.
- Timothy J. Legg, PhD, PsyD, CAADC, CARN-AP, MACAnswers represent the opinions of our medical experts.
- Patients with AWS may also present with concomitant diseases that require treatment (e.g., alcoholic hepatitis, complicated cirrhosis) or develop AWS during periods of hospitalization for unrelated comorbidities.

How Is Alcohol Withdrawal Syndrome Diagnosed?
Seizures, while scary on their own, can also be a warning sign of the DTs. Someone who does have a seizure during detox will likely be transferred to a hospital setting, as seizures tend to repeat.
This article deals only with seizures occurring during alcohol withdrawal in adults. Alcohol enhances the effect of GABA on GABA-A neuroreceptors, resulting in decreased overall brain excitability. Chronic exposure to alcohol results in a compensatory decrease of GABA-A neuroreceptor response to GABA, evidenced by increasing tolerance of the effects of alcohol. Both binge drinking and alcohol use disorder can have health consequences.
The nurse also documents the patient's vital signs, looking for an upward trend indicating increased withdrawal symptoms. On a scale of 0 to 3 , the nurse then rates key signs and symptoms such as nausea/vomiting; tremors; diaphoresis; anxiety; agitation; tactile, auditory, and visual disturbances; headache; and orientation. For example, a patient whose arms or body are visibly shaking while in bed rates a score of 3 for tremors. A patient who has tremors only when extending the arms would rate a score of 2. A patient who has fingertip tremors that are not visible but can be felt by the nurse rates a score of 1.
A nasogastric tube was placed, with immediate return of 400 ml of dark-brown and “coffee grounds” material. Intravenous normal saline, vancomycin, cefepime, and metronidazole were administered.

Chance JF. Emergency department treatment of alcohol withdrawal seizures with phenytoin. The patient was homeless but had recently been enrolled in an addiction treatment program in a residential clinical stabilization service. He reportedly left the program 4 days before admission to this hospital and then “blacked out” daily in tandem with drinking 0.5 to 1 gallon of vodka throughout the day. On the evening before admission, he decided to stop drinking alcohol. Approximately 10 hours later, he awoke on the ground without recollection of lying down; he had had vivid dreams and tremulousness and was worried that he may have had a seizure.

Substances Impairing Recovery
Because close monitoring is not available in ambulatory treatment, a fixed-schedule regimen should be used. Alcohol withdrawal syndrome https://ecosoberhouse.com/ is mediated by a variety of mechanisms. The brain maintains neurochemical balance through inhibitory and excitatory neurotransmitters.
It is hypothesized that seizure activity propagates from the IC to deep layers of the superior colliculus to trigger the wild running phase of the audiogenic seizure. The deep layers of the superior colliculus send projections directly to the spinal cord via the pontine reticular formation and the periaqueductal gray. The periaqueductal gray is thought to trigger clonic seizures, whereas the pontine reticular formation is implicated in the generation of the tonic phase of audiogenic seizures . Some evidence suggests that the IC plays a role in alcohol withdrawal seizures in humans, as it does in rodents.
How Alcohol Causes Seizures
As with almost all things, when used in moderation alcohol is pretty harmless. Having a bottle of beer or a glass of wine on occasion isn’t likely to cause any problems, and it’s almost certain that it won’t lead to a seizure.
Is a useful tool to assess alcohol withdrawal severity that can help guide management and prevent complications in patients diagnosed with AWS. Our use of rapid review methodology may increase the chance of inaccuracies in our study assessments vis-à-vis a formal systematic review.
Symptoms may also include auditory illusions and hallucinations that frequently are accusatory and threatening; patients are usually apprehensive and may be terrified by the hallucinations and by vivid, frightening dreams. Tolerance to alcohol develops rapidly; similar amounts cause less intoxication. Tolerance is caused by adaptational changes of central nervous system cells and by induction of metabolic enzymes. People who develop tolerance may reach an incredibly high blood alcohol content . However, ethanol tolerance is incomplete, and considerable intoxication and impairment occur with a large enough amount.
When it comes to alcohol addiction, many people have simply lost control. Also, alcohol tends to act like gamma-aminobutyric acid in the brain.
Different risk scores are used in clinical practice due to varying advantages and limitations. In patients with a slow metabolism (e.g., the elderly, those with liver failure).
Pharmacologic Treatment Of Withdrawal
Adjunctive treatment with a beta blocker should be considered in patients with coronary artery disease, who may not tolerate the strain that alcohol withdrawal can place on the cardiovascular system. Clonidine also has been shown to improve the autonomic symptoms of withdrawal.10 Although phenytoin does not treat withdrawal seizures, it is an appropriate adjunct in patients with an underlying seizure disorder. Several medications may be helpful adjuncts to benzodiazepines in the treatment of alcohol withdrawal syndrome.
Alcohol-related seizures are generalized seizures, meaning they tend to affect the whole brain. These are the seizures you see on TV where the person falls to the ground in convulsions. As you can imagine, falling can result in injury – anything from a scraped knee to a severe concussion. Also, people can experience Wernicke-Korsakoff Syndrome which causes encephalopathy as well as mental psychosis.
