Dementia Vs Delirium: Top 6 Differences & Symptoms

Do you have a loved one suffering from delirium or dementia? It’s important to know the differences, causes, and symptoms of these two conditions so you’re prepared to take care of your loved one. If you are researching the differences between delirium vs. dementia, we have compiled a list of the symptoms and signs you need to be familiar with.

What Are the Differences Between Delirium and Dementia?

1. Onset Of the 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 diseases such as Alzheimer’s—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

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.
