How to: Recognise the main types of Dementia

Jul 31, 2024 | Advice

Dementia is a disease that affects millions of people worldwide, including many in the UK. Understanding the different types of dementia is key to providing better care, early diagnosis, and improving the quality of life for those affected. It also helps families to navigate the challenges of caring for loved ones with dementia, so they can provide the care they need.

In this article, we’ll explore the main types of dementia, their symptoms, risk factors, and how they impact the brain.

What is Dementia?

Dementia is not a single disease; it is a term used to describe a set of symptoms that happen when brain cells stop working properly. These symptoms can include memory loss, difficulty thinking and problems with social skills. Dementia affects people differently, with symptoms depending on the type of dementia and the part of the brain affected. Let’s take a look at the main types of dementia in the UK.

Alzheimer’s

Alzheimer’s is the most common type of dementia, accounting for between 60-80% of cases. Common symptoms of Alzheimer’s include memory loss, confusion, and mood changes. As the disease progresses, symptoms worsen, leading to significant impairment in daily activities.

Early symptoms of Alzheimer’s might include difficulty remembering recent events, forgetting the names of everyday objects, or getting lost in familiar places. These symptoms interfere with daily life as the disease advances, making Alzheimer’s the most common form of dementia.

Vascular Dementia

Vascular dementia is the second most common type of dementia in the UK, caused by reduced blood flow to the brain. This is often due to blood vessel disease, such as a stroke or a series of mini-strokes which damage the brain’s blood vessels. Vascular dementia symptoms can come on suddenly or over time and can include memory problems, confusion and physical movement and coordination difficulties.

People with vascular dementia may also experience sleep disturbances, bladder control issues and mood changes. Symptoms vary depending on the part of the brain affected by reduced blood flow.

Frontotemporal Dementia

Frontotemporal dementia (FTD) is a rarer type of dementia that affects the frontal and temporal lobes of the brain. FTD is more likely to happen at a younger age than other types of dementia, with many cases developing in people under 65, a condition known as young onset dementia.

Symptoms depend on which part of the frontal or temporal lobes is affected and can vary greatly from person to person. Unlike Alzheimer’s, memory loss isn’t the first symptom, but language problems or changes in behaviour are.

Dementia with Lewy Bodies

Dementia with Lewy bodies is another common form of dementia in the UK. This type of Dementia is caused by the abnormal accumulation of a protein in the brain, known as Lewy bodies. These deposits disrupt the brain’s normal functioning, causing a range of symptoms including visual hallucinations, fluctuations in attention, and Parkinsonism (symptoms similar to Parkinson’s disease).

People with Lewy body dementia may also experience sleep disturbances such as acting out dreams and movement problems similar to Parkinson’s disease. This type of dementia can be hard to diagnose as its symptoms often overlap with Alzheimer’s and Parkinson’s.

Other Dementia Conditions

There are also other less common types of dementia, such as Huntington’s disease which can lead to dementia. Mixed dementia is another where more than one type of dementia occurs at the same time, most often Alzheimer’s and vascular dementia.

Risk Factors and Prevention

The risk of dementia increases with age but other factors like high blood pressure, too much alcohol and poor diet can also contribute. Some research suggests that a healthy diet, staying mentally active and managing underlying medical conditions may reduce the risk of dementia.

Diagnosis and Treatment

Diagnosing dementia typically involves thoroughly reviewing medical history, physical examination, and cognitive testing. Currently, there is no cure but detecting dementia and early diagnosis can help manage symptoms and slow progression. Treatments may include medication, lifestyle changes and supportive therapies to improve cognitive function and quality of life.

Living with Dementia

Living with dementia requires a supportive environment where individuals can maintain their dignity and independence for as long as possible. It’s important to adapt to their changing needs and provide a calm, comforting space. Encouraging participation in activities that bring pleasure and purpose can significantly improve their well-being.

Frequently Asked Questions

What are the main types of dementia in the UK?

The main types of dementia in the UK include:

  • Alzheimer’s Disease: The most common type, characterised by memory loss, confusion, and cognitive decline.
  • Vascular Dementia: Caused by reduced blood flow to the brain, leading to symptoms like memory problems, confusion, and difficulties with movement.
  • Frontotemporal Dementia (FTD): A rarer form affecting the frontal and temporal lobes, leading to changes in personality, behaviour, and language skills.
  • Dementia with Lewy Bodies: Marked by the buildup of Lewy bodies in the brain, causing visual hallucinations, fluctuations in attention, and Parkinson’s-like symptoms.

How do symptoms vary between different types of dementia?

Symptoms of dementia can vary significantly depending on the type:

  • Alzheimer’s Disease: Typically starts with memory loss and progresses to include confusion, mood changes, and difficulties with thinking and reasoning.
  • Vascular Dementia: Symptoms often relate to the specific areas of the brain affected by reduced blood flow and may include problems with planning, decision-making, and movement.
  • Frontotemporal Dementia: Early symptoms often involve personality changes, inappropriate behaviour, or language difficulties, rather than memory loss.
  • Dementia with Lewy Bodies: Characterised by visual hallucinations, fluctuating alertness, and motor symptoms similar to Parkinson’s disease, such as tremors and stiffness.

Can younger people develop dementia, and if so, what types are most common?

Yes, dementia can affect younger people, typically under the age of 65, which is referred to as young onset dementia or early onset dementia. The types most commonly associated with younger age include:

  • Alzheimer’s Disease: Although more common in older adults, it can also occur in younger individuals.
  • Frontotemporal Dementia: This type is more likely to affect people at a younger age compared to other forms of dementia.
  • Vascular Dementia: It can develop at a younger age, particularly in individuals with a history of stroke or blood vessel disease.
