What is Delirium?

Delirium is a sudden change in mental status that leads to confusion and difficulty focusing. It’s usually caused by an underlying issue like infection, medication, or disrupted sleep. 

There are three types:

  • Hyperactive – Restlessness, rapid mood changes, hallucinations. 

  • Hypoactive – Sluggishness, fatigue, lack of response. 

  • Mixed – Symptoms from both types that can change quickly. 

Who is Most at Risk?

How the Care Team Can Help

The hospital team uses daily screening tools and strategies to prevent or reduce delirium: 

  • Encouraging movement and walking (when cleared) 

  • Promoting daytime wakefulness and nighttime rest 

  • Managing pain appropriately 

  • Limiting or adjusting medications that can cause confusion 

  • Treating infections and correcting imbalances 

  • Reducing nighttime interruptions 

What You Can Do to Help

Family and caregivers play an important role: 

  • Share your loved one’s normal routines and behaviors with staff 

  • Help reorient the patient using photos or favorite belongings 

  • Keep lights on during the day and quiet/dark at night 

  • Minimize visitors and noise during rest times 

  • Avoid arguing—offer reassurance instead 

  • Use simple, clear instructions and give time to respond 

  • Bring hearing aids and glasses to improve connection with surroundings 

Does Delirium Go Away?

In most cases, yes—delirium improves once the cause is treated. However, some patients may continue to have mild memory or thinking problems even after discharge. 

Possible Long-Term Effects

While delirium is usually temporary, it can have lingering effects: 

  • Some burn patients show signs of cognitive difficulty after rehab 

  • Longer duration of delirium may lead to greater challenges with memory, decision-making, or daily tasks
