Alcohol withdrawal syndrome is a range of symptoms that occur when a person with alcohol use disorder (AUD) stops or significantly reduces their alcohol intake. Symptoms can range from mild to severe, with the most severe cases being life-threatening. Mild symptoms include anxiety, nervousness, irritability, insomnia, upset stomach, and excessive sweating. More severe symptoms include hallucinations, seizures, high blood pressure, fever, and delirium tremens, which can be life-threatening. Withdrawal symptoms typically begin within 6 to 24 hours of the last drink and worsen at 24 to 72 hours, improving by seven days. It is important to seek medical help and support from doctors, friends, and family when going through alcohol withdrawal to manage discomfort and respond to any medical emergencies.

What You'll Learn
Nutritional deficiencies
Alcohol abuse causes a folate deficiency, which is necessary for the production of new cells, especially in the intestine and the blood. A lack of folate devastates digestive function. Alcohol also depletes carotenoids, a major source of vitamin A and E, and can cause a thiamine deficiency, which is linked to brain shrinkage in chronic alcoholics.
Chronic alcoholics often exhibit neurological disorders related to nutritional deficiencies, particularly vitamin deficiencies that are essential for normal brain function. These include deficiencies in thiamine, nicotinic acid, pyridoxine, and vitamin B12. The clinical presentation of brain-damaged alcoholics varies and includes cognitive impairment, amnesia, and dementia.
Mineral deficiencies are also common in alcoholics. For example, alcohol abuse can cause decreased calcium absorption due to fat malabsorption, magnesium deficiency due to poor diet and vomiting, iron deficiency due to gastrointestinal bleeding, and zinc losses related to other nutrient deficiencies.
Overall, nutritional deficiencies caused by alcohol abuse can have severe health consequences, including damage to the liver and brain.

Alcohol hallucinosis
The symptoms of alcohol hallucinosis can be highly distressing and may result in violent suicide. However, they usually subside within 48 to 72 hours after alcohol cessation. Treatment with neuroleptics and benzodiazepines has proven effective in normalising symptoms. Additionally, abstinence from alcohol, along with the use of neuroleptics, has been shown to be an effective management strategy.
It is important to differentiate alcohol hallucinosis from delirium tremens (DTs), a more severe form of alcohol withdrawal syndrome. DTs do not appear suddenly, and they take approximately 48 to 72 hours to appear after alcohol cessation. A tremor develops in the hands and can also affect the head and body, leading to severe uncoordination. Unlike alcohol hallucinosis, untreated DTs can be fatal.
In summary, alcohol hallucinosis is a rare complication of chronic alcohol abuse characterised by auditory hallucinations, paranoia, and fear. It is caused by an interplay of dopamine and NMDA receptor dysfunction, likely triggered in individuals with a genetic predisposition to psychosis. While symptoms usually subside within 48 to 72 hours, effective treatments with neuroleptics and benzodiazepines are available.

Alcohol withdrawal delirium
AWD can occur when a person with a history of heavy alcohol use abruptly stops drinking or significantly reduces their alcohol intake. Heavy drinking is defined as consuming 15 drinks a week for men and eight drinks a week for women, and binge drinking is the most common form of heavy drinking. For women, it is defined as consuming four or more drinks in one sitting, and for men, it is defined as five or more drinks in one sitting.
The risk of developing AWD is higher for those with a history of heavy, long-term drinking. About 50% of people with alcohol addiction will experience withdrawal symptoms if they stop drinking abruptly, and 3 to 5% of those people will experience AWD symptoms. The symptoms of AWD can set in 48 to 72 hours after the last drink and typically peak five days after onset, beginning to decrease about five to seven days later.
The symptoms of AWD can include grand mal seizures, severe confusion, hallucinations, agitation, extreme sweating, and altered mental status. It is important to seek medical help if you or someone you know is experiencing these symptoms, as AWD can be life-threatening and requires urgent intervention. Treatment for AWD often involves pharmacological approaches, such as benzodiazepines, and close monitoring of vital signs and electrolyte imbalances.

Treatment options
Alcohol withdrawal symptoms can range from mild to severe, with the most severe cases being life-threatening. Treatment options will vary depending on the severity of the symptoms. Here are some common treatment strategies for alcohol withdrawal:
Mild Alcohol Withdrawal Treatment
Mild alcohol withdrawal symptoms, such as anxiety, headache, gastrointestinal discomfort, and insomnia, can often be managed without medical intervention. Creating a quiet, supportive environment for the patient is recommended. One-to-one contact and reorientation can also help.
Moderate Alcohol Withdrawal Treatment
For moderate alcohol withdrawal, benzodiazepines or barbiturates are typically the first-line therapy. These medications help reduce the risk of seizures and delirium tremens, a severe form of alcohol withdrawal. Benzodiazepines are effective in treating alcohol withdrawal as they can safely replace the alcohol-depressant effects on the central nervous system (CNS). A "symptom-triggered approach" is recommended, where the patient is frequently assessed, and the dosage is adjusted accordingly. Other medications that may be prescribed include beta-blockers or clonidine for high blood pressure and fast heart rate, and carbamazepine or gabapentin to reduce cravings.
Severe Alcohol Withdrawal Treatment
Severe alcohol withdrawal, such as delirium tremens, can be life-threatening and requires urgent medical intervention. Treatment often occurs in intensive care units (ICUs) or detoxification facilities, where patients are continuously monitored to prevent life-threatening complications. Benzodiazepines are also used in these cases, typically IV diazepam or IV lorazepam. Additionally, treatment for alcohol use disorder (AUD) is encouraged, which may involve a combination of group psychotherapy and medications.
Underlying AUD Treatment
It is important to address the underlying AUD to prevent relapse and manage alcohol withdrawal effectively. There are three FDA-approved medications for AUD: naltrexone, acamprosate, and disulfiram. These medications can be started before discharge to reduce the chances of readmission. Psychiatric or chemical dependence assessments are also recommended after controlling acute withdrawal symptoms.

Underlying causes
Alcohol withdrawal symptoms occur when a person with an alcohol use disorder (AUD) stops or significantly reduces their alcohol intake. AUD is characterised by a loss of control over alcohol consumption and negative emotions when not drinking. It is a chronic relapsing brain disorder, with genetic, environmental, and physiological factors contributing to its development and maintenance.
The underlying cause of alcohol withdrawal symptoms is the physiological dependence on alcohol that develops over time. When alcohol is consumed heavily and regularly, the body's central nervous system (CNS) gets used to the depressant effects of alcohol and adapts to keep the body functioning. This adaptation means the CNS becomes overactive in the absence of alcohol, leading to a range of physical and mental withdrawal symptoms.
The severity of alcohol withdrawal symptoms is influenced by several factors, including the degree of alcohol intake, the duration of alcohol use, and previous history of alcohol withdrawal. Binge drinking and repeated cycles of intoxication and detoxification can increase the severity of withdrawal symptoms and the risk of complications.
Alcohol use can also lead to nutritional deficiencies, particularly a lack of thiamine (vitamin B1), which is important for nervous system health. These deficiencies can contribute to the physical and mental symptoms experienced during withdrawal.
Additionally, alcohol withdrawal symptoms can be influenced by underlying medical or neurological conditions. For example, alcohol-related seizures must be distinguished from those caused by medical issues such as mineral or electrolyte abnormalities, strokes, or brain tumours. Therefore, an accurate diagnosis of alcohol withdrawal syndrome should consider and rule out other potential causes of similar symptoms.
