Alzheimer’s Disease And Dementia: What Is The Difference
November 22, 2017
People are sometimes confused as to which term to use – Alzheimer’s disease or dementia – and what they mean. In some cases, these two terms can be used interchangeably, but there’s a clear distinction between their definitions. Below is the explanation on how Alzheimer’s disease and dementia are different and what they have in common.
What is dementia?
Dementia is an umbrella term used to describe diseases marked by cognitive decline. Alzheimer’s disease is the most common form of dementia; according to WebMD, about 60% to 80% of people with dementia have Alzheimer’s. Other types of dementia include vascular dementia, dementia with Lewy bodies, mixed dementia (has multiple causes), frontotemporal dementia, Creutzfeldt-Jakob disease, Huntington’s disease, and normal pressure hydrocephalus. People who have Parkinson’s disease also develop dementia. Other factors that may lead to dementia symptoms include infections (such as HIV), stroke, depression, and drug abuse.
