Delirium tremens (DTs) is a severe medical condition that mostly occurs during alcohol withdrawal. However, alcohol withdrawal is not the only cause of DTs. In some cases, it begins with mild symptoms such as restlessness, anxiety, or tremors. The symptoms then get serious, including confusion, hallucinations, and even fast heartbeats. Without proper medical assistance, the condition may become fatal.
This condition primarily affects people with a history of heavy drinking and usually occurs when they suddenly stop drinking. However, it is not automatic that everyone with alcohol use disorder will develop DTs. We will discuss the various aspects of delirium tremens, its symptoms, risk factors, diagnosis, and how to maintain safety and proper health.
Delirium tremens in cases of alcohol withdrawal is a medical emergency that occurs when you stop drinking alcohol suddenly, despite a history of heavy alcohol use. DTs is the most serious form of alcohol withdrawal, and without proper treatment, it can lead to severe effects, including death. Even though the condition is rare, it usually requires immediate attention when it happens.
Delirium tremens is caused by a sudden drop in alcohol levels in the body after long-term use. Alcohol hinders brain activity, and after long-term use, your brain adjusts to the levels and subsequent impacts. Your brain starts to work extra to stay balanced. Therefore, when you suddenly stop, your brain becomes overstimulated and the symptoms of DTs begin.
The condition is not common, but it is seen more in people who have previously experienced alcohol withdrawal. Older people with other medical conditions may also be at higher risk. According to studies, 3% to 5% of people withdrawing from alcohol develop DTS. Occasional or short-time drinkers may not easily develop delirium tremens. When it is not addressed, the risk of fatalities is as high as 30%. However, with proper medication, the risk of death lowers to 1% to 4%.
Timeline of Symptoms
The initial symptoms of alcohol withdrawal, such as nausea, shaking, sweating, and anxiety, typically begin within six to twelve hours. Hallucinations start within twelve to twenty-four hours, while seizures are experienced within twenty-four to forty-eight hours. Delirium tremens does not occur right after you stop drinking. It appears on the third to fifth day after you stop drinking, and can last for 24 hours to six days.
The most severe symptoms of delirium tremens, such as extremely high heart rate, hallucinations, agitation, and confusion, can last between three and five days and require immediate medical attention.
Recognizing Symptoms of Delirium Tremens
There are physical and psychological signs of delirium tremens. They include:
Physical Symptoms
Severe shaking
Excessive sweating
Fast heart rate
Increased breathing
Increased blood pressure
Fever
Nausea or vomit
Loss of appetite
Seizures
Psychological and Neurological Symptoms
Confusion
Hallucinations
Fear
Disorientation
Restlessness
Risk Factors for Developing Delirium Tremens (DTs)
You do not automatically experience delirium tremens if you suddenly stop heavy drinking. However, various factors increase the risk of these conditions. They include:
Severity and Duration of Alcohol Use
The amount of alcohol and the frequency of drinking matter a lot. If you regularly drink, say 20 – 30 standard drinks or more than 240g of alcohol in a day, you are highly at risk of DTs. This is especially true if you drink strong spirits. Long-term heavy drinking severely impacts your brain functioning, forcing your brain to adapt to the constant alcohol. The system, therefore, becomes overactive when you stop suddenly, potentially leading to DTs symptoms.
Repeated unsuccessful attempts to detox may also intensify withdrawal. Every episode pushes your brain to act stronger, a condition known as “kindling”.
Previous History of Withdrawal
Your medical history also determines if you are at a higher risk of experiencing delirium tremens. If you have previously experienced delirium tremens or withdrawal seizures, you are likely to develop DTs again. Similarly, if you have previously been hospitalized for severe withdrawal or required medical attention in prior detox, you are at a much higher risk.
Other Important Risk Factors
Age: Older people are at a greater risk because their brains and bodies recover more slowly. As a result, they may suffer from weak resilience during withdrawal.
Underlying Health Issue: If you have a head injury, heart disease, or liver condition, your body may be unable to handle stress well. As a result, if you develop DTs, which is likely, you may experience worse effects.
Electrolyte Imbalance: Low levels of magnesium or potassium in the body also increase the risk of DTs and seizures. Normal-range low levels of potassium have been associated with higher risks of death in delirium tremens.
Poor Health/Nutrition: If an illness weakens your body or you are malnourished, your risks increase.
Complications Associated with Delirium Tremens
Delirium tremens has both short and long-term effects, some of which can be fatal. Recognizing the health risks is a crucial step to seeking help and promoting safety. Here are the common health risks associated with DTs:
Short-term Health Risks
Seizures are the most common short-term risks that potentially occur within 24 to 48 hours after you stop drinking. They may be clustered or prolonged, with increased risk of trauma or brain injury if left unaddressed.
You may also develop a harmful high body temperature. The fever is often accompanied by high blood pressure and rapid heart rate, which strain your heart. This can lead to cardiovascular collapse or abnormal cardiac rhythms and an increased risk of death.
Additionally, you may suffer from dehydration linked to excessive vomiting, sweating, or loss of appetite. With less fluid in your body, blood pressure and kidney function may drop drastically. This intensifies existing heart problems and risks organ failure.
Bed sores or inhaling vomit are also possible, which can lead to infections. Pneumonia is also possible, and when all these factors combine with DTs, the risk of mortality goes up.
The risk of injury is high because of agitation and confusion. You may even remove medical devices. Sometimes restraints are used for those with severe delirium tremens. However, restraints present higher risks of injury and even death when they are misused.
Long-term Implications
One long-term health risk linked to delirium tremens is lasting thinking and memory challenges. DTs causes chronic memory loss, learning problems, and confusion. Some survivors also develop Wernicke‑Korsakoff syndrome. Constant withdrawal may also destroy neuron pathways, which may further contribute to cognitive decline. Even mild brain damage may increase the risk of dementia.
People with delirium tremens may also relapse to heavy drinking, suffer organ damage, or develop other health problems. The risks of death are also higher. As one study reports, 1% to 15% mortality within a few years was seen in people with DTS. Moreover, you may suffer from ongoing health issues such as persistent insomnia, anxiety, malnutrition, liver damage, or heart disease, which will further worsen your health.
Diagnosing Delirium Tremens (DTs)
Diagnosis of delirium tremens is a very comprehensive process since alcohol withdrawal is not the only cause. The diagnosis includes assessments, observation, and tests.
Medical Assessment Procedures
The doctors begin by gathering information about your medical history. They typically record how much alcohol and how long you have been drinking. They may ask the last time you were drunk and note any withdrawal episodes or symptoms of DTs. Since alcohol withdrawal is not the only cause of DTs, the doctors will also check for any other health issues to assess your risk level.
After assessments, physical exams follow to check for any vital signs. The doctor may inspect you for fever, tremors, or dehydration. They will also listen to your lungs and heart. Depending on the circumstances, the doctors may assess your focus, orientation, hallucinations, and alertness.
Additionally, the doctors will use standard scales to evaluate the severity of withdrawal. The Richmond Agitation Sedation Scale (RASS) and 4AT tests help to detect fluctuating awareness and agitation linked to delirium. The Clinical Institute Withdrawal Assessment (CIWA-Ar) is used to track symptoms like hallucinations, anxiety, nausea, and tremors. High scores suggest a greater likelihood of delirium tremens.
The diagnosis also includes laboratory tests to rule out any other potential cause of delirium. The doctors will check alcohol and blood levels in your body. They will also test your glucose, blood count, liver function, and electrolytes. Sometimes, a lumbar puncture or urine test may be necessary to exclude meningitis. Similarly, MRI or CT scans may be done to rule out brain injury or stroke if the symptoms suggest their existence.
Treatment and Management of Delirium Tremens
Delirium tremens is a severe condition that can be life-threatening. As a result, after diagnosis, the next stage is proper treatment and management. This includes:
Hospitalization
Delirium tremens is a medical emergency that usually requires immediate attention in an intensive care unit (ICU). The potential symptoms and risks, such as cardiac arrhythmias, confusion, autonomic instability, and seizures, require constant monitoring and care. Inpatient care, therefore, allows professionals to manage the symptoms correctly and prevent further harm.
Medication
Benzodiazepines are the primary medication for delirium tremens. Particularly, lorazepam and diazepam are preferred based on the clinical context and treatment regimen. Benzodiazepines reduce the risk of seizures and manage several symptoms of alcohol withdrawal, including DTs. This is because they increase the effect of gamma-aminobutyric acid (GABA), which is reduced during alcohol withdrawal. When these drugs alone do not work, barbiturates may be used as well.
Similarly, antipsychotics such as Haldol (haloperidol) are used to reduce agitation and manage hallucinations. This helps you think clearly and maintain proper focus.
Since delirium tremens also comes with dehydration and mineral deficiencies, the doctors may infuse you with a substance containing B9 (folate), B1 (thiamine), electrolyte solution, a multivitamin, etc. These will help restore fluid balance in your body.
Recovery and Rehabilitation
Once you stabilize, a structured post-acute care becomes necessary. In most cases, this begins with detox in a medically supervised program, then potentially a transfer to a rehabilitation center. The doctors will then continue monitoring your situation for any psychiatric or cognitive impairment symptoms.
Rehabilitation, on the other hand, can be outpatient or inpatient depending on individual needs and the severity of dependence. Most rehabilitation programs adopt a holistic approach composed of cognitive behavioral therapy (CBT), group therapy, motivational interviewing, intensive outpatient programs, or 12-step programs like Alcoholics Anonymous (AA).
Aftercare is also crucial for sustained recovery without further episodes of DTs or relapse. A good program for long-term recovery will consist of mental health care for any co-occurring disorders, pharmacotherapy such as disulfiram, acamprosate, or naltrexone, and social support from friends, family, community programs, or peers. Ensure you maintain regular contact with your healthcare providers to remain on track with recovery.
It is very much possible to prevent delirium tremens. The key lies in recognizing alcohol dependence, carefully planning for withdrawal, and maintaining sobriety. Here are crucial tips:
Controlled and Supervised Withdrawal
A medically supervised detox program is perhaps one of the most effective ways to prevent delirium tremens. This is particularly true if you have a history of heavy and long-term alcohol use. In such a setting, professionals will help you manage withdrawal gradually using medication that reduces the central nervous system’s hyperactivity and prevents severe agitation and seizures.
Accredited detox facilities also monitor electrolyte levels, fluid balance, and crucial signs to prevent complications.
Lifestyle Change and Support Systems
Long-term abstinence goes beyond medical detox. It begins with you identifying the need to reduce or avoid drinking alcohol. This also means adhering to the recommended guidelines in the 2020-2025 Dietary Guidelines. These include two standard drinks a day for men, and a single standard drink a day for women. If you are a teenager, it may be well to completely avoid alcohol even if you have attained the legal age for alcohol consumption in your country.
Adopting a healthy lifestyle also includes healthy routines, avoiding alcohol environments, and embracing stress reduction techniques. Teach yourself mindfulness techniques to help you manage stress.
It is also vital to consider individual counseling to identify and address the root causes of alcohol use, and support groups for peer support, accountability, insights, and encouragement. Family therapy also enhances communication and rebuilds bonds that may have been damaged by alcohol dependence or delirium tremens. A strong support system encourages lasting recovery and prevents relapse.
