What Are the Differences Between Delirium and Dementia?
Delirium and dementia are both conditions that affect cognitive function, but they differ in their onset, duration, and underlying causes. The differences between delirium and dementia are the following:
1. Onset of Symptoms
One difference between delirium and dementia is the onset of symptoms. Delirium is known as an acute confusional state. The condition occurs when someone experiences an abrupt change in their ability to remember things. On the other hand, dementia progresses slowly over a more extended time period. It is important to seek medical attention if your loved one is experiencing abrupt symptoms of delirium.
2. Risk Factors
If you are comparing the differences between delirium and dementia, delirium can be caused by conditions such as pneumonia, drug use or withdrawal, and dehydration. Mixing prescription medications can cause delirium as well. Some common risk factors for delirium include old age, severe medical conditions, and the use of certain medications. Dementia usually is caused by health conditions such as Alzheimer’s disease—which is a specific type of dementia. Other types of dementia include vascular dementia, lewy body dementia, and frontotemporal dementia. Some common risk factors for dementia include aging, family history of memory issues, and underlying health conditions.
3. Longevity
Delirium is generally a temporary condition that improves over time—if treated properly. It can last anywhere from a couple of days to a couple of months. Whereas dementia is an incurable, long-term condition that worsens over time.
4. Communication Skills
One of the more difficult giveaways of delirium vs dementia is through communication. Delirium can significantly affect one’s ability to communicate clearly with others. People with dementia also often struggle with finding the right words and expressing themselves.

5. Memory & Concentration Skills
If you are analyzing the distinctive characteristics of delirium vs dementia, it’s important to know that individuals with delirium have functioning memory but deteriorating alertness. However, people with dementia have higher alertness but impaired memory.
6. Responsiveness & Activity
A person with delirium experiences either a significant increase or decrease in activity level. On the other hand, activity levels in people with dementia are typically normal until later stages.
3 Types of Delirium
1. Hyperactive
Hyperactive delirium occurs when an individual experiences a significant increase in daily activity levels. This type of delirium is characterized by restlessness, agitation, mood changes, hallucinations, and a rejection of care from family members, friends, and healthcare professionals.
2. Hypoactive
Hypoactive delirium occurs when an individual experiences a significant decrease in daily activity levels. This type of delirium is characterized by lethargy, sluggishness, drowsiness, and dazed behavior.
3. Mixed
A person with mixed delirium transitions between temporary phases of hyperactive and hypoactive delirium. This type is characterized by the symptoms listed above, but the individual switches back and forth between them.
