Alzheimer’s Dementia: What Is This New Term?
Per the 2017 Alzheimer's Disease Facts and Figures [PDF] report published by the Alzheimer’s Association, there is now a distinction made between Alzheimer’s disease and Alzheimer’s dementia.

This change in language comes at a time when researchers, scientists, and physicians seek to diagnose and treat this irreversible neurodegenerative condition long before cognitive impairment manifests.
 

What Is Alzheimer’s Disease?


The term Alzheimer’s disease refers to the entire process of neurodegeneration. The disease process spans many years where a person is living with biological markers that are indicative of risk factors of the disease and may have no symptoms, to the stage where functional cognitive impairment is evident, to the end stage of the disease process.
