All you need to know about Delirium Tremens

The idea of “seeing pink elephants” has been used for decades to describe someone who’s had too much to drink. While not used as much today, if you take a look at old cartoons or films, you may hear the term being used. But the origin of that image isn’t random and comes from a very real and very serious medical condition called delirium tremens.

Delirium tremens is the most severe form of alcohol withdrawal and it’s classified as a medical emergency. If you or someone you love has been drinking heavily for a period of time and are looking to quit for good, delirium tremens is something you need to understand.

What are delirium tremens?

Before we begin this article, it’s important to state that experiencing delirium tremens is classed as rare and most people who go through alcohol withdrawal won’t experience it. Studies note that while more than half of people with alcohol use disorder will have some withdrawal symptoms when they stop drinking, only around 3 to 5% develop symptoms severe enough to reach what is classed as delirium tremens.

But for those who do develop it, the severity is something that has to be addressed in a clinical environment. Without appropriate treatment, the mortality rate can reach as high as 37% but with proper medical care, that number drops significantly.

What causes delirium tremens?

The reason DTs happen comes down to what alcohol does to the brain when it’s present in the system day after day over a long period of time.

Alcohol is a depressant and it works by enhancing the brain’s calming signals and suppressing the excitatory ones, which is why drinking makes you feel relaxed. But heavy drinking over months or years forces the brain to compensate. It dials down its own calming activity, which is managed by a chemical system called GABA and ramps up the excitatory side, which is driven by a chemical called glutamate.

This is almost like a tug of war, with alcohol pulling the brain in one direction and the brain pulling back to stay balanced. The longer the drinking continues, the harder the brain pulls. When the alcohol is suddenly removed, the brain is still pulling with everything it has, but there’s nothing on the other side of the rope anymore. The result is a surge of neurological overactivity that the body wasn’t designed to handle.

At its most extreme, this is what produces delirium tremens.

What are the symptoms of delirium tremens?

Alcohol withdrawal usually follows a recognisable pattern, although the timing can vary depending on how much or how long a person has been drinking. Knowing what to expect at each stage helps to make sense of where DT fits in.

Early withdrawal (6 to 24 hours)

The first signs usually present within a few hours of the last drink. Experts describe the early symptoms as:

• Anxiety
• Insomnia
• Palpitations
• Headache
• Gastrointestinal symptoms

These symptoms are uncomfortable but manageable for most people with the right support around them.

When symptoms escalate into delirium tremens (48 hours onwards)

DTs typically start from around 48 hours after the last drink and can last up to five days. A separate clinical review notes that the risk window can extend as far as eight days after stopping drinking.

The thing that separates DTs from everything that came before it is what is described as profound global confusion and this is the hallmark of the condition. The person becomes severely disoriented and they may not know where they are or be able to communicate clearly.

On top of the confusion, the clinical literature documents the following symptoms:

• Visual hallucinations
• Extreme agitation
• Rapid heart rate
• High blood pressure
• Fever
• Heavy sweating
• Tremors
• Seizures

In standard alcohol withdrawal, a person remains oriented and aware, even if they feel terrible. In DTs, that awareness breaks down entirely. That loss of orientation, combined with severe physical instability, is what makes the condition so dangerous.

Who is most at risk for experiencing delirium tremens?

Not everyone who stops drinking will develop DTs and understanding who is most vulnerable can help you assess your own level of risk. StatPearls identifies several factors that make DTs more likely:

• A previous episode of DTs
• A history of withdrawal seizures
• Concurrent medical illness or infections
• Previous detoxification attempts
• Older age
• Low potassium levels

The common thread running through all of these is heavy, prolonged alcohol use. The longer and more heavily a person has been drinking, the more the brain has adapted to alcohol’s presence and the more severe the rebound tends to be when it’s taken away.

Physical condition at the point of withdrawal matters too. Most people who develop DTs arrive at the hospital with severe dehydration, sometimes with a fluid deficit of up to 10 litres. Poor nutritional status and electrolyte imbalances are common alongside this, which compounds the danger.

Why delirium tremens is a medical emergency

DTs cannot be safely managed at home as the complications that can develop need the kind of monitoring that’s only available in a supervised medical setting.

Research notes that deaths from DTs mostly result from associated medical conditions and cardiac arrhythmias. Seizures, dangerous spikes in body temperature, electrolyte imbalances, respiratory failure and cardiovascular collapse are all documented complications.

The NHS advises that for people with severe alcohol dependency, detox may need to take place in a hospital or in a clinic because the withdrawal symptoms are likely to require specialist treatment.

The NHS also states that stopping drinking suddenly can be very dangerous if you’re dependent on alcohol.

In a hospital setting, the priority is to bring nervous system activity back down to a safe level. This is typically done using sedatives such as benzodiazepines, which work on the same GABA system that alcohol previously stimulated. Alongside this, IV fluids are given to address the severe dehydration that most DTs patients present with and vitamins, including thiamine (B1) are administered to prevent further neurological complications.

The condition is treatable when caught early and managed properly, which is exactly why getting to a medical setting as quickly as possible matters so much.

This is the reality that anyone with an alcohol dependency needs to be aware of. Attempting to detox without medical guidance carries a real risk and for those vulnerable to DTs, medical supervision during alcohol withdrawal can be the difference between a safe detox and a fatal one.
