What Is Dementia?

Dementia is not a specific disease — it’s an umbrella term that describes a group of symptoms affecting memory, reasoning, and communication. Think of it like the word "fever" — it tells you something’s wrong but not what the root cause is.

There are many types of dementia, including:

Alzheimer’s disease (the most common form)

Vascular dementia

Lewy body dementia

Frontotemporal dementia

Each has its own causes and patterns of progression, but they all impact cognitive function in significant ways.

What Is Alzheimer’s Disease?

Alzheimer’s is a specific brain disease and the leading cause of dementia, accounting for up to 70% of cases worldwide.

It’s characterized by:

Buildup of amyloid plaques and tau tangles in the brain

Gradual memory loss

Changes in behavior and personality

Difficulty with daily activities

While dementia is a broad category, Alzheimer’s is one particular disease under that umbrella.
