The current evidence favors symptom-triggered treatment, as it reduces the average length of stay, the total dosage of administered benzodiazepines, and the level of patient sedation. CIWA-Ar can be used to guide the need for symptom-triggered medication and ancillary rescue medication if a patient is on a fixed-dose schedule. Alcohol withdrawal is one of the most common causes of adult-onset seizures.

Similarly, in humans, epileptiform activity is rarely observed in the EEG between episodes of alcohol withdrawal–related tonic–clonic seizures (12,13). Thus, alcohol withdrawal seizures are unlikely to be triggered in the neocortex. Indeed, electrophysiological studies have demonstrated a critical role for the inferior colliculus (IC) in the initiation of audiogenic seizures in rodents. The IC external cortex is believed to amplify and propagate neuronal activity originating in the IC central nucleus. Neurons within the deep layers of the superior colliculus (16) and the periaqueductal gray (17) also may play a role in the initiation of audiogenic seizures. It is hypothesized that seizure activity propagates from the IC to deep layers of the superior colliculus (a major output of the IC) to trigger the wild running phase of the audiogenic seizure.
How Is Alcohol Withdrawal Treated?
Alcohol (ethanol) depresses (slows down) your central nervous system (CNS). If you consistently consume significant amounts of alcohol, your CNS gets used to this effect. Your CNS must work harder to overcome the depressant effects of alcohol to keep your body functioning.
Alcohol Withdrawal Syndrome: Symptoms, Causes, Treatment, and More
However, because high doses may cause respiratory depression, vital signs must be carefully monitored with each loading dose to avoid benzodiazepine toxicity, especially in patients with liver disease. In the second approach repeated fixed doses at regular intervals are administered; this strategy can be particularly useful when it is difficult to assess and monitor progression of withdrawal signs. After the patient is stable for 2 to 3 days, are alcohol withdrawal seizures dangerous the benzodiazepine can be slowly tapered over 7 to 10 days. In elderly patients or those with liver disease, repeated administration of shorter-acting benzodiazepines such as oxazepam or lorazepam may be safer. A third approach is symptom-guided by monitoring instruments such as the revised Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar), which is a 10-item scale that can be administered at the bedside within 5 minutes.
Introduction ‐ Medical Burden of Alcohol Abuse
Chemical dependence is one of the most significant factors in your risk of experiencing dangerous withdrawal symptoms when you quit drinking. Alcohol dependence occurs after a period of consistent drinking or frequent binge drinking. Drinking every once in a while and even heavy drinking on the weekends may not lead to chemical dependence on alcohol, although it could lead to other dangerous consequences.
- This review provides an overview of the current understanding of the cellular and molecular events that lead to alcohol withdrawal seizures.
- Alcohol and other central nervous system depressants keep that channel open, causing more intense sedating effects.
- This may be accompanied by a groan or cry as air is forced through the vocal cords.
- Barbiturates such as phenobarbital can be used to treat alcohol withdrawal but are far less commonly employed than benzodiazepines because of their narrow therapeutic index.
- They can also suffer from extreme fatigue and a migraine-like headache once the muscle contractions have stopped.
- In fact, people suffering from chronic alcohol abuse increase their risk of developing seizures when they suddenly stop drinking.
- When that person cuts out alcohol, there is a period when their brain hasn’t yet received the message and still overproduces the stimulating chemicals.
- These seizures are mediated largely in the brainstem, although the hippocampus may be invaded after seizure initiation (10).
- Patients who have had prior complicated withdrawals should not attempt to decrease their alcohol intake without consultation with their healthcare team.
