The terms dementia and Alzheimer’s are often used interchangeably. However, they are not the same condition. Understanding the difference between the two can help families recognise symptoms, seek the right support and plan appropriate care for a loved one.
Are dementia and Alzheimer’s the same?
No, dementia and Alzheimer’s are not the same. Dementia is an umbrella term used to describe a group of symptoms that affect memory and other cognitive functions. These symptoms are caused by different diseases or conditions that damage the brain. There are over 100 types of dementia, Alzheimer’s being the most prominent one.
Alzheimer’s disease is one specific condition that causes dementia. In the UK, it accounts for around 60-70% of dementia cases. This means that while many people living with dementia have Alzheimer’s, dementia can also be caused by other conditions.
Here’s some more details on dementia and Alzheimer’s disease, to help highlight the differences.
What is dementia?
Dementia refers to a collection of symptoms rather than one specific condition. These symptoms usually worsen over time and can affect many areas of someone’s life.
Common symptoms of dementia include:
- Memory loss that interferes with daily life
- Difficulty concentrating or problem-solving
- Confusion about time or place
- Changes in mood, personality or behaviour
- Difficulties with communication and understanding
- Struggling with familiar tasks.
What causes dementia?
Dementia can be caused by several different conditions, including but not limited to:
- Alzheimer’s disease
- Vascular dementia
- Lewy body dementia
- Frontotemporal dementia
- Mixed dementia (a combination of causes).
Each type can affect the brain in different ways and may progress at different speeds. For example, vascular dementia can occur because of damage to the brain from something like a stroke. Dementia with Lewy bodies is caused by ‘tiny clumps of a protein called alpha-synuclein that can develop inside brain cells. These clumps damage the way the cells work and communicate with each other, and the brain cells eventually die.
What is Alzheimer’s disease?
Alzheimer’s disease is a progressive neurological condition that damages brain cells over time. It is characterised by the build-up of two abnormal proteins called amyloid and tau.
The build-up of these proteins causes deposits known as ‘plaques’ and ‘tangles’ in the brain, which interfere with how brain cells communicate and eventually causes them to die.
Early symptoms of Alzheimer’s often include:
- Short-term memory loss
- Repeating questions or conversations
- Misplacing items
- Difficulty finding words
- Subtle changes in mood or judgement.
As the disease progresses, symptoms typically become more severe. This can result in increased confusion and disorientation, significant memory loss and difficulty recognising loved ones. It can also cause problems with mobility and swallowing and increases the need for support with personal care.
Key differences between dementia and Alzheimer’s
The main difference is that dementia describes a set of symptoms, while Alzheimer’s disease is one specific condition that causes dementia.
Dementia can result from different underlying causes, meaning symptoms, progression and care needs may vary from person to person.
Alzheimer’s follows a more recognisable pattern of gradual and steady cognitive decline, often starting with memory problems before affecting other functions. Other types of dementia, such as vascular dementia, may progress in stages rather than gradually.
Why understanding the difference matters
Knowing whether your loved one has Alzheimer’s disease or another type of dementia can help ensure they receive the correct diagnosis and treatment plan. It will also help set realistic expectations about how their symptoms may change and progress.
Understanding the type of dementia your loved one has also allows for their care and support to be tailored to their specific needs, as well as providing them access to the appropriate specialist services and support networks.
A formal diagnosis is usually made by a GP or specialist through assessments, medical history and brain scans.
Supporting a loved one with dementia or Alzheimer’s
Caring for someone living with dementia or Alzheimer’s can be emotionally and physically challenging. As the condition progresses, your loved one may need increasing support with daily tasks, personal care, medication and emotional reassurance.
