Dementia vs. Alzheimer's: What's the Difference?

Dementia is a general term that refers to a decline in cognitive function that affects daily life. Alzheimer's disease is the most common type of dementia, accounting for 60-80% of cases. However, there are several other types of dementia, and the symptoms and causes can vary.

The main difference between dementia and Alzheimer's disease is that dementia is a broader term that encompasses a range of symptoms, while Alzheimer's disease is a specific type of dementia with its own set of symptoms and causes.

Dementia can be caused by a variety of factors, including Alzheimer's disease, Parkinson's disease, Huntington's disease, and vascular dementia, among others. The symptoms of dementia can include memory loss, difficulty communicating, changes in mood or personality, and difficulty with daily tasks.

Alzheimer's disease, on the other hand, is characterized by the accumulation of beta-amyloid plaques and tau protein tangles in the brain, which leads to the death of brain cells and a decline in cognitive function. The symptoms of Alzheimer's disease can include memory loss, difficulty with language and communication, difficulty with problem-solving and decision-making, and changes in mood and behavior.

While Alzheimer's disease is a type of dementia, not all dementia is caused by Alzheimer's disease. Other types of dementia may have different causes and symptoms, and may require different treatments. It's important to speak with a healthcare professional if you or a loved one is experiencing symptoms of dementia or Alzheimer's disease, in order to get an accurate diagnosis and appropriate treatment.
