Understanding the Difference Between Alzheimer’s and Dementia
Dementia and Alzheimer’s are often confused, but they’re not the same. Understanding the difference helps families find the right support and plan for the future.
What is Dementia?
Dementia is not a single disease. Instead, it’s an umbrella term used to describe a range of symptoms that affect memory, thinking, communication, and daily life.
Common symptoms of dementia include:
Memory loss
Confusion or disorientation
Difficulty with language and communication
Changes in mood or behaviour
Struggles with everyday tasks
There are several types of dementia, and each can affect people in slightly different ways.
What is Alzheimer’s?
Alzheimer’s disease is the most common cause of dementia, accounting for around 60–70% of all cases. It is a specific brain disease that causes the gradual build-up of abnormal proteins in the brain, leading to the death of brain cells over time.
Symptoms of Alzheimer’s often begin with short-term memory problems — forgetting recent conversations or where items have been placed. Over time, it can affect reasoning, communication, recognition of loved ones, and eventually the ability to carry out basic daily tasks.
Key Differences Between Dementia and Alzheimer’s
- Dementia is a general term for symptoms that affect memory, thinking, and daily life.
Alzheimer’s disease is one specific type of dementia — but not the only one. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia.
Not everyone with dementia has Alzheimer’s.
Think of it this way: all Alzheimer’s is dementia, but not all dementia is Alzheimer’s.
Why Understanding the Difference Matters
Knowing the difference between Alzheimer’s and dementia makes a real impact for families. It means being able to seek the right diagnosis and support, and it helps explain why symptoms can vary so much from one person to another.
For example, while Alzheimer’s usually begins with memory problems and gradually worsens, vascular dementia often develops after a stroke or a series of small strokes. Its symptoms can be different — sometimes affecting problem-solving, decision-making, or movement before memory.
With the right understanding, families can access appropriate treatment, explore lifestyle support, and plan care that truly reflects their loved one’s needs.
An early diagnosis is especially important — it gives families the chance to put support in place, learn more about the condition, and help their loved one live well at home for as long as possible.
