Alzheimer’s vs Dementia – What’s the Difference?

It’s very common to hear the words Alzheimer’s and dementia used interchangeably. In fact, many families we support at Homelium tell us they didn’t realise there was a difference.

While the two terms are closely connected, they’re not the same thing. Understanding how they differ can help families feel more informed, more confident and better prepared to support their loved one.

What is Dementia?

Dementia is not a disease in itself. Instead, it’s an umbrella term used to describe a collection of symptoms that affect the brain. These symptoms are usually severe enough to interfere with daily life and independence.

Common signs of dementia include:

• Memory loss that disrupts everyday life

• Difficulty with problem-solving or planning

• Challenges with language and communication

• Changes in behaviour, mood, or judgement

It’s important to know that there are different types of dementia, each with its own causes, symptoms and patterns. These include vascular dementia, Lewy body dementia and frontotemporal dementia, among others.

What is Alzheimer’s?

Alzheimer’s disease is the most common type of dementia, responsible for around 60–70% of all cases.

Unlike the broader term “dementia,” Alzheimer’s is a specific, progressive brain disease. It causes brain cells to shrink and die, leading to:

• Gradual memory loss

• Increasing confusion

• Difficulties with daily tasks

• Behavioural and personality changes

Alzheimer’s usually develops slowly, with symptoms worsening over time. While there is currently no cure, support and care can make a huge difference to quality of life.

Alzheimer’s vs Dementia: The Key Difference

Think of it this way:

• Dementia = the condition (a group of symptoms)

• Alzheimer’s = one of the causes of dementia

In other words, all Alzheimer’s is dementia, but not all dementia is Alzheimer’s.

Why This Matters for Families

Understanding these terms isn’t just about language, it’s about support. Knowing whether a loved one has Alzheimer’s or another type of dementia helps families:

• Access the right information and resources

• Plan care that’s tailored to their needs

• Feel more confident in making decisions together
