Understanding Delirium: A Comprehensive Guide
1. Overview
Delirium is a serious medical condition characterized by sudden confusion, changes in behavior, and altered consciousness. It is often a sign of an underlying medical issue and requires prompt attention. In the U.S., delirium is relatively common among hospitalized patients, affecting approximately 15-26% of older adults during their hospital stay. While delirium can occur at any age, it is more prevalent in older adults. Delirium can be acute, meaning it comes on suddenly and lasts for a short period, or it can be chronic, lasting for weeks or even months.
2. Symptoms

Symptoms of delirium can progress rapidly over a period of hours or days. Early warning signs may include sleep disturbances, irritability, and memory problems.
3. Causes & Risk Factors
Delirium can be caused by a variety of factors, including underlying medical conditions, infections, medications, and substance abuse. Risk factors for delirium include advanced age, underlying dementia, immobility, sensory impairment, and recent surgery or hospitalization.
4. Diagnosis
Diagnosing delirium involves a thorough medical evaluation, including blood tests, imaging studies, and sometimes a neurological examination. Primary care doctors may initially diagnose delirium, but a specialist, such as a neurologist or psychiatrist, may be consulted for further evaluation.

7. Complications & When to See a Doctor
Complications of delirium can be severe and may include long-term cognitive impairment or functional decline. Seek urgent medical care if delirium is accompanied by seizures, severe agitation, or a sudden change in mental status.
8. Living with the Condition
Managing delirium may involve ongoing medical treatment, support from caregivers, and participation in support groups. In the U.S., resources such as the Alzheimer’s Association and local hospitals may offer support for individuals with delirium. Workplace considerations may include disability benefits and rights under the Americans with Disabilities Act (ADA).
9. FAQs
