Dementia is an umbrella term. An individual may have dementia, but not necessarily have Alzheimer’s. Alzheimer’s tends to be a catch all term for those older adults living with memory loss, but this disease requires a medical diagnosis, which is not always 100% accurate.
There are over 80 different types of Dementia, with Alzheimer’s being only one. A few examples of Dementia include: Lewy Body, Frontotemporal, and Parkinson’s. It is typically a challenge for doctors to determine exactly what type of dementia an individual has without doing a brain autopsy after the individual passes away.
