What are the symptoms of delirium?
Delirium indicates a widespread disruption in brain activity. That means there are many possible symptoms of delirium. It’s also important to remember the symptoms may look different from one person to the next. It can also fluctuate. Delirium can often get better during the day and worse as nighttime approaches, which is why this condition sometimes gets the incorrect name of “sundowning.” The main symptom of delirium is confusion. That means you have trouble with: Focusing or shifting your attention when necessary. Thinking and concentrating. Remembering facts, events, people, etc. Staying aware of your surroundings. Answering correctly when asked what time it is, the date and where you are. Trouble speaking clearly, answering questions or understanding what others are saying. Trouble processing what you see, including identifying objects or where you are. Feeling more emotional, scared or angry. Symptom patterns of delirium tend to fall into one of three categories: Hyperactive. Hypoactive. Mixed.
What causes delirium?
Available research indicates that delirium is a complex condition that doesn’t happen for a single reason. Instead, delirium occurs when the “balancing act” between your functional capacity, your functional limitations and other stressors gets pushed too far. On one side is your functional capacity. That’s how much you can handle and recover from without being overwhelmed. On the other side are stressors. That’s anything that makes it harder for your body to work as it should. Functional capacity (+) Functional limitations (-) Stressors that can cause or contribute to delirium (-) Physical health. Chronic health conditions. Acute (sudden) illnesses. Mental health. Mental health conditions. New or chronic injuries. Energy level. Increasing age. Medical procedures, surgeries or hospital stays. Diet. Poor diet. Stress. Trouble hearing or seeing what’s happening around you. Lack of sleep. Lack of mobility. Lack of social interaction. Lack of natural light to help you tell day from night.

Functional limitations (-) Stressors that can cause or contribute to delirium (-) Lack of natural light to help you tell day from night. Your body and mind can keep working or recover from problems as long as you have enough functional capacity. But risk factors reduce your functional reserve. The more stressors and risk factors you have, the easier it is for delirium to happen. When stressors outweigh your functional reserve capacity — either on their own or because risk factors make you more vulnerable — you can develop delirium.
What are the complications of delirium?
Delirium involves widespread disruption in brain activity, which can lead to many complications. They range from minor and short-lived to severe and permanent. Complications to know about include: New-onset dementia or worsening of existing dementia. Falls and traumatic injuries. Long-term or permanent brain function problems (cognitive impairment). Inability to care for yourself, leading to a loss of independence. Depression, post-traumatic stress disorder (PTSD) and other mental health conditions. Loss of physical abilities. Advertisement
How is it diagnosed?
A healthcare provider diagnoses delirium based on a combination of methods. These include: A physical exam. A neurological exam. Observing your behavior and any symptoms you show. Talking to you and asking questions. A review of your medical history. Lab testing.
How is delirium treated, and is there a cure?
There’s no specific treatment or medication for delirium. Instead, healthcare providers will treat causes and contributing factors they can identify. Helping people with mobility and activity or removing tethers can help delirium get better. Monitoring and adjusting medications can also help improve delirium while you undergo treatment for the underlying causes.
Is delirium preventable?
Delirium is often preventable, but most preventive measures are things only clinical personnel should do. However, family, friends and loved ones can play a very important role in reducing the risk of delirium. Don’t try to help a loved one with delirium unless a healthcare provider (especially your loved one’s physician or nurse) tells you it’s OK to do so. Following the guidance of trained healthcare providers is key to keeping both you and your loved one safe from harm.
What can I expect if I have delirium?
If you have delirium, the disruption in your brain function means you won’t be truly aware of or able to understand what’s happening to you. It also affects your memory, judgment and control over what you say and do. While delirium is temporary, the effects and symptoms can sometimes linger. This is especially true when delirium is severe or goes untreated. However, even with treatment, the effects can be long-lasting. Because of that, the best way to manage delirium is to prevent it from ever happening (or at least to limit the effects).
What’s the outlook for delirium?
The outlook for delirium can vary widely. In general, the outlook tends to be worse when delirium goes undiagnosed for long periods, or when it’s particularly severe. Delirium can affect your physical and mental health, quality of life and your overall sense of well-being, especially when it’s severe. In more severe or long-lasting cases, delirium can cause you to develop dementia or make existing dementia worse. In the most severe cases, delirium can cause disability or significantly increase your risk of death. Because the outlook can vary widely, your healthcare provider (or your loved one’s provider) is the best person to tell you what the outlook is for your specific situation. They can tailor that information to reflect all the positive and negative factors that play a role.
How do I take care of myself?
If you have delirium, it severely disrupts how your brain works. Having delirium means you can’t take care of yourself and have to rely on others for help. When delirium is more severe, you need higher levels of care, typically in a medical setting. If your loved one has delirium in a medical setting, they need regular medical care. Once their delirium subsides, they may still have lingering effects. Your loved one’s healthcare provider can tell you more about those effects, what they mean, how long they’re likely to last and what kind of care or assistance your loved one will need.
What is delirium tremens, and is it the same as delirium?
Delirium tremens (sometimes informally known as “DT” or the plural “DTs”) is a symptom of withdrawal from alcohol misuse and alcohol use disorder. It’s also known as “alcohol withdrawal delirium.” The condition gets its name because it causes the confusion-related symptoms that make up delirium, and it also causes tremors or shakes, particularly in your hands. Delirium tremens is a dangerous symptom of alcohol withdrawal, and people who have this symptom need emergency medical care. A note from Cleveland Clinic If you have a loved one with delirium, it can feel scary or overwhelming to see them act confused or not like themselves. Delirium is a condition that healthcare providers are better prepared to recognize and manage. They also have a wide range of techniques they can use to try to prevent it. More importantly, you can also help prevent delirium in a loved one. If you have questions about delirium, your healthcare provider or your loved one’s provider can give you information and guidance. They can tell you more about this condition, including what you can do to reduce the chances of developing it yourself. They can also tell you what you should and shouldn’t do to help prevent delirium in a loved one. Medically Reviewed Last reviewed by a Cleveland Clinic medical professional on 02/22/2023.
