Understanding Delirium: More Than Just Confusion
Delirium is a serious and sudden change in mental function, characterized by confused thinking and reduced awareness of the environment. Unlike dementia, which develops slowly, delirium appears acutely over hours or days. It's a medical emergency that is often a sign of an underlying illness. The prevalence of delirium in hospitalized older adults can be as high as 56%, and it occurs in up to 87% of those in intensive care, making it a significant concern in senior care.
The Crucial First Step: Identify and Treat the Underlying Cause
The first and most important step in the treatment of delirium is to identify its underlying cause and address that trigger directly. Delirium itself is a syndrome, not a disease, and it is almost always precipitated by another medical issue. Treating the symptoms of delirium without addressing the root cause will not resolve the condition. Healthcare providers will conduct a thorough assessment to pinpoint the trigger, which may involve:
- Medical History Review: Examining recent illnesses, injuries, or new medications.
- Physical and Neurological Exams: Checking for signs of infection, pain, or neurological problems like a stroke.
- Lab Tests: Ordering blood and urine tests to check for infections, dehydration, or electrolyte imbalances.
Common underlying causes that must be investigated include:
- Infections (e.g., urinary tract infections, pneumonia)
- Medication side effects or withdrawal
- Dehydration and electrolyte imbalances
- Recent surgery
- Severe pain
- Constipation or urinary retention
- Low oxygen levels
Supportive Care: Creating a Healing Environment
While the underlying cause is being treated, supportive care is essential to manage symptoms and prevent complications. This is a non-pharmacological approach that focuses on creating a safe and calming environment. These interventions are a cornerstone of delirium management.
Key Non-Pharmacological Strategies:
- Promote Orientation: Regularly remind the person of the time, date, and where they are. Use clocks, calendars, and family photos to provide familiar cues.
- Ensure Proper Sleep-Wake Cycles: Keep the room well-lit during the day and dark and quiet at night. Minimize nighttime interruptions for vitals or medication if possible.
- Encourage Mobility: Help the person get out of bed and move around as soon as it's safe. Early mobilization can significantly reduce delirium duration.
- Manage Sensory Needs: Ensure the individual has their glasses and hearing aids to reduce sensory deprivation, which can worsen confusion.
- Maintain Hydration and Nutrition: Encourage regular intake of fluids and healthy meals.
- Avoid Restraints: Physical restraints can increase agitation and should be avoided. Instead, have a family member or sitter stay with the person if they are at risk of harming themselves.
Pharmacological vs. Non-Pharmacological Approaches
While non-pharmacological interventions are the primary strategy, medication may be used in specific situations. Here’s a comparison:
| Feature | Non-Pharmacological Approach | Pharmacological Approach |
|---|---|---|
| Primary Goal | Create a safe, healing environment and manage symptoms through support. | Control severe agitation or psychotic symptoms that pose a danger. |
| When to Use | Always. This is the first-line treatment for all cases of delirium. | Used as a last resort when behaviors are dangerous to the patient or others. |
| Common Methods | Re-orientation, mobility, sleep hygiene, hydration, family presence. | Low-dose antipsychotics (e.g., haloperidol, quetiapine). |
| Risks | Minimal; generally very safe. | Significant side effects, can prolong delirium, increased mortality risk in elderly. |
Medications like antipsychotics do not treat delirium itself. They are used sparingly to manage severe symptoms, such as hallucinations or aggression, that prevent necessary medical care or endanger the patient or staff. Benzodiazepines are generally avoided as they can worsen delirium, except in cases of alcohol or sedative withdrawal.
The Road to Recovery
Recovery from delirium can take time, ranging from a few days to several weeks or even months after the underlying cause is resolved. For some, especially those with pre-existing cognitive impairment like dementia, the recovery may be incomplete. Consistent supportive care and rehabilitation are key to helping the person return to their baseline level of function.

Conclusion
In summary, when faced with the question, what is the first step in the treatment of delirium?, the answer is unequivocally to identify and treat the underlying medical condition. This diagnostic detective work, combined with a robust framework of non-pharmacological supportive care, offers the best path to recovery and helps mitigate the serious complications associated with this acute confusional state. Prioritizing this approach ensures that the person is treated holistically, addressing both the immediate symptoms and the root of the problem.
