How Dementia and Alzheimer’s Are Different

Many people use the terms “dementia” and “Alzheimer’s” interchangeably. That’s understandable, because they both refer to conditions people associate with memory loss, confusion and old age. But Alzheimer’s disease is just one type of dementia. There are many other types of dementia that cause problems with memory and thinking. Read on to learn more about the difference between dementia and Alzheimer’s disease.
What is Dementia?
Think of dementia as a general category of symptoms that affect the brain. Different groups of symptoms suggest specific types of dementia. Alzheimer’s is the most common type of dementia, affecting one in 10 Americans 65 and older. Next to Alzheimer’s, there are three types of dementia that are most common. All have different symptoms.- Vascular dementia is the second most common form of dementia. It usually results from a stroke. Symptoms include difficulties with problem-solving, slowed thinking, focus and organization.
- Lewy body dementia causes symptoms similar to Alzheimer’s. Other symptoms include hallucinations and fearfulness. This type of dementia occurs when abnormal clumps of protein develop inside nerve cells in the brain.
- Frontotemporal dementia often makes it difficult to understand or produce language and/or causes changes in behavior and personality. This type of dementia damages nerve cells in the frontal lobe of the brain.
